    Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentiation, callus proliferation, and regeneration. Because of the infrequent occurrence of such a genotype in sugar beet populations, our protocol includes an in vitro propagation method for germplasm preservation. The starting materials for transgenic experiments are aseptic shoots grown from surface-sterilized seed balls. Callus is induced from leaf explants and subsequently infected with Agrobacterium. Plantlets are regenerated from transgenic callus and vernalized for flowering, if necessary. The efficiency of transformation was quite high; in our laboratory, the culture of only ten leaf explants, on average, generated one transgenic plant. PMID:25300853

    Full Text Available Root rot diseases of sugar beet caused by Rhizoctonia solani (AG 2-2 IIIB and AG 2-2 IV, R. crocorum, Aphanomyces cochlioides, Phoma betae, Macrophomina phaeseolina, Fusarium oxysporum f.sp. radicis-betae, Pythium aphanidermatum Phytophthora drechsleri, Rhizopus stolonifer, R. arrhizus and Sclerotium rolfsii cause significant losses wherever sugar beets are grown. However, not all these soil-borne pathogens have been reported in all sugar beet production areas. Losses include reduced harvestable tonnage and reduced white sugar recovery. Many of these pathogens also cause post harvest losses in storage piles. Control for diseases caused by these pathogens include disease resistant cultivars, avoidance of stresses, cultural practices such as water management and the use of fungicides.

  16. Oxidative enzymatic gelation of sugar beet pectin for emulsion stabilization

    DEFF Research Database (Denmark)

    Abang Zaidel, Dayang Norulfairuz; Meyer, Anne S.

    2013-01-01

    Pectin from sugar beet is derived from the sugar beet pulp residue which results when sugar beets are processed for sucrose extraction. The sugar beet pectin has poor gelationability by the classic divalentcation molecular mechanism because of a relatively high acetylation degree and short...... polygalacturonate backbone chain length. However, due to the feruloyl-substitutions on the side chains, the sugar beet pectic polysaccharides can be cross-linked via enzyme catalyzed oxidation. The enzyme kinetics and functionality of such oxidativelycross-linked sugar beet pectin, in relation to stabilizing...... emulsions has recently been investigated in model food emulsions. This paper reviews the pectin chemistry, enzymatic oxidative gelation mechanisms, interaction mechanisms of the sugar beet pectin with the emulsion droplets and explores how the gelation affects the rheology and stability of emulsion systems...

    2003-02-12

    Geosmin provides the characteristic but sometimes undesirable "earthy" flavor to red table beets. To date, it is not known whether geosmin is a byproduct of beet metabolism or synthesized by soil-borne microorganisms and taken up by the beets during maturation. Analysis of mature beet roots revealed that peels contained 6 times the amount of geosmin compared to the bodies and cores. Sterilized beet seeds were aseptically grown in a basal medium prior to analysis for the presence of geosmin. Using a headspace solid-phase microextraction (HSPME) method, the relative recovery of geosmin from beet seedling extracts was 72.0 +/- 4.2% with (-)-menthone as the internal standard. The presence of geosmin in aseptically grown beet seedlings was confirmed by gas chromatography-mass spectrometry using authentic geosmin as the standard. During aseptic growth, the concentration of geosmin in seedlings remained constant for up to 5 months but increased at 6 months. Geosmin added to the growth medium was not absorbed by the seedlings. These studies support the conclusion that red beets are capable of endogenous synthesis of geosmin. PMID:12568567

    Full Text Available The structure and function of the plant microbiome is driven by plant species and prevailing environmental conditions. Effectuated by breeding efforts, modern crops diverge genetically and phenotypically from their wild relatives but little is known about consequences for the associated microbiota. Therefore, we studied bacterial rhizosphere communities associated with the wild beet B. vulgaris ssp. maritima grown in their natural habitat soil from coastal drift lines (CS and modern sugar beets (Beta vulgaris ssp. vulgaris cultivated in CS and potting soil (PS under greenhouse conditions. Analysis of 16S rRNA gene fingerprints and pyrosequencing-based amplicon libraries revealed plant genotype- and soil-specific microbiomes. Wild beet plants harbor distinct operational taxonomic units (OTUs and a more diverse bacterial community than the domesticated sugar beet plants. Although the rhizospheres of both plant genotypes were dominated by Proteobacteria and Planctomycetes, 47.4% of dominant OTUs were additionally detected in the wild beet rhizosphere. Analysis of the cultivable fraction confirmed these plant genotype-specific differences at functional level. The proportion of isolates displayed in vitro activity against phytopathogens was lower for wild beet (≤45.8% than for sugar beet (≤57.5%. Conversely, active isolates from the wild beet exhibited stronger ability to cope with abiotic stresses. From all samples, active isolates of Stenotrophomonas rhizophila were frequently identified. In addition, soil type-specific impacts on the composition of bacterial communities were found: Acidobacteria, Chloroflexi, and Planctomycetes were only detected in plants cultivated in CS; whereas Bacteroidetes and Proteobacteria dominated in PS. Overall, in comparison to modern sugar beets, wild beets were associated with taxonomically and functionally distinct microbiomes.

  8. BREAK-EVEN POINT IN SUGAR-BEET PRODUCTION

    2015-05-01

    Full Text Available World sugar consumption has been recording a steady growth in the past 70 years and, according to all relevant estimates, it will continue to grow also in the next decade, which puts sugar in the category of the most significant foods and commodities in the world. Of the total world sugar production, around 77% is derived from sugar cane and 23% from sugar beet. Brazil has been the world leader in sugar production for a long period of time, producing white sugar from sugar cane only, whereas the leader in the production of sugar derived from sugar beet is the EU-28. When the Republic of Croatia joined the EU, the Croatian sugar industry became part of the single European sugar market, so the break-even point was used in the research to determine the competitiveness level of the Croatian sugar beet production. Based on the expected selling price of sugar beet amounting to EUR 34 per ton of standard quality sugar beet, and using the break-even method, it was determined that the quantity required to cover total costs in sugar beet production in the Republic of Croatia amounts to 55.26 tons per hectare of payable sugar beet, standard quality, i.e. 8.84 tons of polarized sugar per hectare. As the average sugar beet production in the Republic of Croatia, expressed in the equivalent of polarized sugar, amounts to 7.8 tons per hectare, it is obvious that an average Croatian producer of sugar beet, without income from subsidies, operates at a loss.

  15. γ-irradiation of wild beet translocation lines and monosomic addition lines in sugar beet carrying nematode resistance genes

    International Nuclear Information System (INIS)

    The beet cyst nematode (BCN, Heterodera schachtii Schmidt) is a severe pest in sugar beet (Beta vulgaris L.). The only sources of resistance are distantly related wild beet species such as Beta procumbens. Sugar beet lines, carrying a translocation from B. procumbens chromosome 1, display complete resistance to the BCN. A nematode resistance gene, designated Hs2pro-7, had been cloned from the translocation line A906001. This gene gave complete resistance in a complementation study done with sugar beet hairy roots, however only partial resistance was found in whole sugar beet plants transformed with the same construct. There are strong indications for a second resistance gene on this translocation designated Hs1-1. Unfortunately, the resistance gene cannot be fine mapped due to complete lack of recombination on the wild beet translocation. In order to narrow down to the target region for Hs1-1, a mutant screening among the offspring of γ- irradiated beets was done. 2670 seeds from a translocation line were irradiated with 100 Gy and 578 resistant M1-offspring were analysed with three molecular markers spread around the translocation. Mutants are presently detected by the absence of molecular markers. A second screening at irradiation levels of 200 and 400 Gy was done and the plants are being analysed. Another experiment was started to produce translocations carrying the B. procumbens chromosome 7 which houses the Hs2pro-7 gene for nematode resistance. This resistance has not been broken by virulent pathotypes of H. schachtii as demonstrated with monosomic addition lines. To select resistant plants with a translocation derived from chromosome 7, 2826 seeds of monosomic addition lines of chromosome 7 were irradiated with 400 Gy. The M1-families will be tested for their resistance and the size of the chromosome fragment introduced will be determined by molecular marker analysis. (author)

    In this study, biochemical methane potential (BMP) assay was conducted to investigate the effect of waste mixing and F/M ratio on the co-digestion of wastewater and beet-pulp, in addition to the digestion of the wastes separately. In the studied F/M range (0.51-2.56 g COD/g VSS), observed treatment efficiencies (63.7-87.3% COD removal and 69.6-89.3% VS reduction) were indications of high biodegradability for both wastewater and beet-pulp, which decreased with increasing F/M. It was evident that the extent of biomethanation of wastewater was higher than beet-pulp, owing to the inherent soluble carbohydrates in wastewater. When the co-digestion of the wastes was evaluated, it came up with the result that, major outcome of wastewater addition was to increase methane production rate of beet-pulp, rather than increasing its ultimate biodegradability. Indeed, modeled first-order rate functions indicated that rate constants (k values) differentiated in the ranges between 0.081 and 0.143 day{sup -1} and 0.028-0.050 day{sup -1} respectively for wastewater added and non-added reactors. These results indicated that anaerobic co-digestion of wastewater and beet-pulp is promising since wastewater addition significantly increases the rate of biomethanation of beet-pulp. (author)

    Abolishment of EU sugar quotas will lead to lower sugar and sugar beet prices in the EU, leading to lower margins for farms. At the same time, expansion of sugar beet growing and processing in a quota-free situation can decrease fixed cost per ha of sugar beet and per kg of sugar, making both sugar beet growing and processing more efficient. Besides, lower sugar price levels will make Europe a more attractive continent for investments by sugar-based industries.

    Full Text Available ABSTRACT This study aimed to evaluate the distribution of salts along the soil profile, the biometric parameters and the yield of beet cultivars under different leaching fractions using saline effluent from fish farming, under the conditions of the Sub-middle São Francisco Valley. An experiment was conducted at the Caatinga Experimental Field of the Embrapa Semi-Arid, in 2013. The treatments were arranged in split plots composed of four leaching fractions (0, 5, 10 and 15% in the plots, with saline effluent from fish farming, and three table beet cultivars in the subplots: Scarlet Super, Early Wonder 200 and Fortuna. The analysed parameters were: salt distribution along the soil profile, number of leaves, length and width of leaves and petioles, total and commercial yields. The application of leaching fractions of 10 and 15% promoted better salt distribution along the soil profile. The beet cultivar Fortuna showed the highest commercial yield for a lower leaching fraction.

    Full Text Available In common with the majority of crop species, in sugar beet nutrition nitrogen is an important element due to its role in sucrose utilization and plant growth. Application of precision agriculture, in order to apply the right amount of input at the right time in the right area, is appropriate to decrease chemical use and increase plant growth. Problem statement: More often farmers apply fertilizers with low efficiency, low uniformity and high price such as spinner spreader, boom spreader or application with planting machines simultaneously. Fertigation can reduce labor cost and may improve uniformity, effectiveness and timeliness of application. Approach: The main objective of this study was to determine spatial variability of sugar beet performance affected by urea fertigation as well as established a management strategy based on spatial variability of tubers and soil total N. This study was conducted in Fesaran village, Isfahan Province of Iran and limited to sugar beet (monogerm seed. Urea applied through sprinklers. Soil samples were taken to determine soil total N as well as sugar beet tubers samples to specify yield. Results of soil and crop analysis were used to produce spatial variability maps through GS+ and ArcGIS 9.2 software. Semivariogram results were used to perform an ordinary kriging to obtain interpolated values of selected variables from the sample points through and across the study area. Results: It was found that there was a low spatial variability of soil total N and yield which indicates that the soil has a homogenous total N as well as homogenous yield through and across the field. Yield variability map of sugar beet properties demonstrated that the higher yield was seen in the southern part of the study area where laterals were closer to pump. Conclusion: The results of urea fertigation through sprinklers showed pipeline layout and pump station position impact on variability of sugar beet properties.

    2016-02-01

    Full Text Available In sugar beet (Beta vulgaris weed control is commonly performed by herbicide application applied broadcast at splitting during the cultivation period. Mechanical weeding can be an alternative to chemical weed control. The aim of this experiment was the estimation of weed control efficacy with the use of automatic steering technologies by camera guidance, the use of different intra row weed control implements in conservation tillage systems and the influence of these techniques to the number of uprooted sugar beets. A field experiment with a randomized complete plot design was conducted in 2015 at Ihinger Hof, Germany. Weed density ranged from 0 to 12 plants m-2 with Chenopodium album, Polygonum convolvulus, Polygonum aviculare as the most abundant weed species. Hoeing with the use of automatic steering technologies reduced the weed density by 82%. The use of finger weeders, rotary-harrow and torsion finger weeder reduced the weed density by 29% compared to common hoeing strategies. Differences in the number of uprooted sugar beets were not found across all treatments. We revealed the possibility of a more intense use of mechanical weeding technologies in combination with precision farming technologies in sugar beet.

    In sugar beet (Beta vulgaris altissima), bolting tolerance is an essential agronomic trait reflecting the bolting response of genotypes after vernalization. Genes involved in induction of sugar beet bolting have now been identified, and evidence suggests that epigenetic factors are involved in their control. Indeed, the time course and amplitude of DNA methylation variations in the shoot apical meristem have been shown to be critical in inducing sugar beet bolting, and a few functional targets of DNA methylation during vernalization have been identified. However, molecular mechanisms controlling bolting tolerance levels among genotypes are still poorly understood. Here, gene expression and DNA methylation profiles were compared in shoot apical meristems of three bolting-resistant and three bolting-sensitive genotypes after vernalization. Using Cot fractionation followed by 454 sequencing of the isolated low-copy DNA, 6231 contigs were obtained that were used along with public sugar beet DNA sequences to design custom Agilent microarrays for expression (56k) and methylation (244k) analyses. A total of 169 differentially expressed genes and 111 differentially methylated regions were identified between resistant and sensitive vernalized genotypes. Fourteen sequences were both differentially expressed and differentially methylated, with a negative correlation between their methylation and expression levels. Genes involved in cold perception, phytohormone signalling, and flowering induction were over-represented and collectively represent an integrative gene network from environmental perception to bolting induction. Altogether, the data suggest that the genotype-dependent control of DNA methylation and expression of an integrative gene network participate in bolting tolerance in sugar beet, opening up perspectives for crop improvement.

    Fodder and sugar beet silage as mono-substrate has been studied for their fermentation behaviour in semi-continuous biogas tests according to VDI guideline 4630. Especially the methane formation potential and the maximum loading rate of different beet varieties are in the focus of investigations. It has been shown that sugar beet silage can be used with a lower loading rate in the biogas digester as fodder beet silage. Here, the methane yields of sugar beet silages tend to be higher than the methane yields of the investigated fodder beet silage. The methane yields of the individual beet silage are not depending on the dry matter content of the investigated beets. In the co-fermentation of corn silage and beet silage, the proportion of beet silage at the dry matter content of the feed is crucial for a stable fermentation process. Furthermore sugar beet silage has economic advantages compared to silage from fodder beets due to a higher methane production potential. The deployment costs of sugar beet silage are significantly depending on the variety and choice of silage method and lie at the level of corn silage. In case of a digestion of the beet variety Mosaik as silage the deployment might be underneath the deployment costs of corn silage. (orig.)

    2015-02-01

    The use of sugar beet in anaerobic digestion (AD) during biogas production can lead to process upsets such as excessive foaming in fermenters. In the present study, foam formation in sugar beet-fed digestates was studied in foaming tests. The increasing disintegration grade of sugar beet was observed to have a promoting effect on foaming in the digestate but did not affect the biogas yield. Chemical analysis of foam and digestate from sugar beet silage AD showed high concentrations of pectin, other carbohydrates and N-containing substances in the foam. Both pectin and sucrose showed little foaming in AD. Nevertheless, sucrose and calcium chloride had a promoting effect on foaming for pectin AD. Salts of divalent ions also enhanced the foam intensity in the case of sugar beet silage AD, whereas ammonium chloride and urea had a lessening effect on sugar beet-based foaming. PMID:25446785

    Full Text Available The use of treated wastewater to irrigate the sugar beet (Beta Vulgaris L. var. saccharifera for bioethanol could play a strategic role to contrast the use of natural water resources and increase the productivity of the crop. The 2-year experiment (2013-2014 was performed on sugar beet irrigated with fresh water and wastewater at different steps of the reclamation process (secondary and tertiary treatments. The data obtained showed that the root sugar beet yield and ethanol production under fresh water treatment (52.2 Mg ha–1 and 5446 L ha–1 were lower respect to that obtained from the secondary and tertiary wastewater treatments (66.7 Mg ha–1 and 6785 L ha–1, and 58.7 Mg h–1 and 6164 L ha–1, respectively, with the same irrigation volumes. These results can depend on the higher quantity of nutrient uptake when wastewater is used for irrigation. In particular, the average N applied (as nitrate and ammonium with irrigation during the growing seasons (2013 and 2014 was corresponding to the supply of 4, 28 and 20 kg ha–1, for the fresh water, secondary, and tertiary wastewater treatments, respectively.

  9. The addition of sugar beet to ethanol pathway in GHGenius

    International Nuclear Information System (INIS)

    Developed by Natural Resources Canada, the GHGenius model is used to estimate the life cycle emissions of primary greenhouse gases (GHGs) as well as the criteria pollutants from combustion sources. The model can be used to analyze the emissions from conventional and alternatively fuelled combustion engines and fuel cell powered trucks and vehicles, as well as light duty powered electric vehicles. Over 140 vehicle and fuel combinations can be used. This paper examined the effects of adding energy used to produce materials consumed in the production of alternative fuels in GHGenius energy balance calculations, as well as vehicle emission calculations on a carbon dioxide (CO2) eq/GJ of fuel consumed basis. This paper also examined the addition of sugar beet ethanol pathways to GHGenius. Energy balances were obtained and a number of process improvements to sugar beet ethanol processing were examined as sensitivity cases. GHGenius was used to calculate the energy consumption of each stage in the production cycle. Estimates included the energy required to produce the chemicals used in the ethanol processing procedure. Results were then compared with results obtained from gasoline, corn and wheat ethanols. Results of the study showed that energy balances were lower than corn or wheat ethanol. Feedstock transmission and processing requirements were also higher due to the higher moisture content of the feedstock. The results of several European studies considering the use of sugar beet ethanol were also included. 17 tabs., 9 figs

    2012-12-01

    Full Text Available The survey investigates into equipment of sugar beet farms of the Lublin region, Poland, with machinery – with reference to plantation size and yields. To assess the production potential of the farms, the authors determined the age structure of the machinery owned by the farmers and established the scale of investment in new equipment. The machinery most important for sugar beet production are pre-sowing and post-harvest tillage units, sprayers, seed drills, combine harvesters and self-unloading trailers. In most cases, the surveyed farmers own most of these machines, but they are often obsolete: 37% of them is in operation for more than 15 years. As for the machines dedicated solely to sugar beet growing (harvesters and seeders, their age structure is most unfavourable – 70% of them have been used for over 15 years. A trend towards increasing plantation sizes provides incentives for introducing innovation to cultivation methods. However, the scale of investment in new machinery is small, especially in the case of small and medium-sized farms that dominate in the region. The authors surveyed also the scale of using professional services in the field of tillage processes to determine changes in farming practices.

    Three commercial neem [Azadirachta indica A. Juss (Meliaceae)]-based insecticides, Agroneem, Ecozin, and Neemix, and a non-commercial neem leaf powder,were evaluated for oviposition deterrence, antifeedant effect on larvae, and toxicity to eggs and larvae of the beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae),on cotton leaves in the laboratory. Oviposition deterrence in no-choice, and two- and fivechoice assays, was observed for the neem-based insecticide treatments when compared with a non-treated control. Neem-based insecticides also deterred feeding by beet armyworm larvae. Direct contact with neem-based insecticides decreased the survival of beet armyworm eggs. Survival of beet armyworm larvae fed for 7 days on leaves treated with neembased insecticides was reduced to 27, 33, 60, and 61% for neem leaf powder, Ecozin,Agroneem, and Neemix, respectively. Possibilities for adoption of neem-based insecticides in commercial cotton for beet armyworm control are discussed.

    Hydrogen can be produced through dark anaerobic fermentation using carbohydrate-rich biomass, and through photofermentation using the organic acids produced from dark fermentation. Sugar beet is an ideal energy crop for fermentative production of hydrogen in the EU due to its environmental profile and its potential availability in the area. In this work, various aspects of cultivating sugar beet in the EU for biohydrogen were highlighted, with special focus on The Netherlands and Greece. Moreover, fermentation of sugar beet juice with Caldicellulosiruptor saccharolyticus at sucrose concentration 10 g/l was performed, and was found comparable to the fermentation on pure sucrose except that the hydrogen production was 10% higher on sugar beet juice. A conservative estimate of the annual hydrogen potential in the EU was made (300x10{sup 6} kg hydrogen), considering the utilization of sugar beet pulp in hydrogen production.

    Although poleroviruses are known to infect a broad range of higher plants, carnivorous plants have not yet been reported as hosts. Here, we describe the first polerovirus naturally infecting the pitcher plant Nepenthes mirabilis. The virus was identified through bioinformatic analysis of NGS transcriptome data. The complete viral genome sequence was assembled from overlapping PCR fragments and shown to share 91.1 % nucleotide sequence identity with the US isolate of beet western yellows virus (BWYV). Further analysis of other N. mirabilis plants revealed the presence of additional BWYV isolates differing by several insertion/deletion mutations in ORF5. PMID:27180098

    Presoaked barley seeds were irradiated with 60-500 R of 300 kV X-rays at a dose rate of 600 R/h. The seeds were sown in plastic containers and grown at 200C in a climatic chamber. A significant increase was observed in all investigated parameters except for the plant length till 250 R. Irradiation of presoaked seeds of sugar beet with 1,000-8,000 R resulted in an increase of root weight and sugar yield after 1,000 R. The irradiation of dry seeds, however, did not cause any stimulation. (MG/AK)

    Being a multi-talented crop, sugar beets are increasingly convincing biogas plant owners with their positive properties. In a mixture of substrates, they are a perfect partner for biogas production as they can push gas yield. In breeding, the experts mainly focus on increasing dry matter yield. There is a close correlation with sugar yield. The market already offers a multitude of highly performing sugar beet varieties for most diverse cropping conditions. The beets are harvested and transported from the field to the biogas plant with harvesting and transport technology which has proved its efficiency for many years. Other than harvested for other purposes, sugar beet for biogas production are stripped of their leaves instead of being topped. Stocking sugar beet at the biogas plant is a quite demanding issue. Sugar beets may be stocked as ensiled, whole beet, as pulp, or as crushed beet in mixed silage. There is a whole range of most diverse storage and crushing concepts. When used as a substrate for biogas production, sugar beet mostly need to be cleaned and stones need to be discarded before feeding the beets into the digester. In the meanwhile, the market offers a large choice of cleaning technique to pave the ways for sugar beets as a substrate. (orig.)

Hybrids included in the experiment are owned by four selection houses and represented in wide production. Weather conditions in the years of investigation differed greatly. One was an average, one with increased, and two with small amounts of rainfall in relation to long-term average. Monthly air temperatures during the vegetation were increased in all four years. Root yield and quality of sugar beet varied considerably depending on the year and the hybrid. The best hybrid on the average of the investigation, by the highest root, was Severina (86.66 t ha-1. Three more hybrids: Coyote, Boomerang and Predator are in the same range. There are no significant differences in this indicator. Hybrid Colonia KWS (15.40% had the highest content of sugar in the root and Asketa, Gazeta, Severina and Protecta with no significant differences. Hybrid Colonia KWS was known for the low content of AmN and Na. Sugar yield, significantly higher than other hybrids in the study, has been realized with hybrids Severina (11.05 t ha-1 and Colonia KWS (10.78 t ha-1.

  14. Effect of low gamma ray doses on sugar beet

    International Nuclear Information System (INIS)

    We studied the effect of presowing irradiation simulation on sugar beet seeds in two regions (Deir Elzour and Damascus) and for three successive cropping seasons (1986-1989). Those seeds were irradiated with gamma radiation doses varying from 0.005 to 0.050 kGy in the first region, and from 0.005 to 0.025 kGy in the second region. Results showed that doses varying from 0.005 to 0.05 kGy in Deir Elzour gave a mean yield increase varying from 17.4% to 22.6%. However, doses varying from 0.005 to 0.025 in Damascus gave an increase of the same parameter between 19.5% and 23.8%. The best results for pure sugar yield increase obtained for a dose of 0.015 kGy (27.1% in Deir Elzour and 31.9% in Damascus). Yields on the farm level obtained from presowing irradiated seeds showed an increase in sugar beets when using 0.015 kGy gamma radiation dose. (author)

    Sugar beet pulp is an abundant industrial waste material that holds a great potential for bioethanol production owing to its high content of cellulose, hemicelluloses, and pectin. Its structural and chemical robustness limits the yield of fermentable sugars obtained by hydrolyzation and represents the main bottleneck for bioethanol production. Physical (ultrasound and thermal) pretreatment methods were tested and combined with enzymatic hydrolysis by cellulase and pectinase to evaluate the most efficient strategy. The optimized hydrolysis process was combined with a fermentation step using a Saccharomyces cerevisiae strain for ethanol production in a single-tank bioreactor. Optimal sugar beet pulp conversion was achieved at a concentration of 60 g/l (39% of dry weight) and a bioreactor stirrer speed of 960 rpm. The maximum ethanol yield was 0.1 g ethanol/g of dry weight (0.25 g ethanol/g total sugar content), the efficiency of ethanol production was 49%, and the productivity of the bioprocess was 0.29 g/l·h, respectively.

  16. Co-pyrolysis of lignite and sugar beet pulp

    International Nuclear Information System (INIS)

    Today, worldwide studies have been undertaken on the biomass usage and co-conversion of biomass and coal to seek out alternative fuels for supplying energy in an environmental friendly way. The objective of this work is to study co-pyrolysis of lignite and sugar beet pulp in 50/50 (wt./wt.) ratio of blend pellets, to elucidate their thermal behaviour under pyrolysis conditions and to assess major decomposition products in terms of their yields. A special chamber, which has enabled very fast heating rates, was used in the pyrolysis experiments carried at 600 deg. C. The results were interpreted in the light of liquid, solid and gaseous yields, resulting from thermal decomposition, and kinetics of thermogravimetric analysis. Proximate volatile matter and ash contents of the blends were different compared to those found by using individual values. Sugar beet pulp decomposed faster within a relatively narrow temperature range than lignite and underwent a significant shrinkage during pyrolysis. It was found that the chars left behind after the flash pyrolysis of these pellets at 600 deg. C have substantial amounts of volatile matter that would evolve upon further heating.

    2014-12-01

    Full Text Available The article presents the results of the research on the current state of the beet sugar subcomplex of Ryazan region in the context of the need of improving its efficiency. The study let the author determine that currently the beet sugar subcomplex of Ryazan region does not ensure domestic demand in sand sugar. However, there are reserves of providing more efficient use of soil and climate capacity as well as the productivity potential of the region. When applying the technology of field beet piling, the period of sugar production at sugar factories may be extended up to 200 days. At this, up to 51 thousand tons of sand sugar can be produced. This amount will completely cover the annual demand for sugar in Ryazan region. In order to further study the feasibility of this approach, zoning was carried out and let allocate the zones of beet seeding. As a result, it was determined that a number of areas are far removed from the place of treatment, and in terms of transportation costs minimization the sugar beet cultivation in these areas is not rational. As an alternative, the author proposes to consider the possibility of building a new sugar factory in Ryazhsky district with the processing capacity of 1,000 tons of sugar beet per day. Taking this into account, the recommended acreage of sugar beet by districts and zones of raw material supply were obtained through corresponding calculations.

    Hydrogen production needs to be based on renewable resources in order to be sustainable. Sugar beet is an ideal raw material for fermentative production of hydrogen in the EU and possibly in the USA due to its environmental profile and its potential availability in these areas. In this work, the fermentative production of hydrogen from sucrose of analytical grade and sugar beet extract by pure cultures of Caldicellulosiruptor saccharolyticus was investigated, under uncontrolled and controlled conditions. In the first case, growth of pure cultures of C. saccharolyticus on sucrose derived from sugar beet was compared to growth of the microorganism on sucrose of analytical grade. The production of hydrogen and organic acids (acetate and lactate) from sugar beet was largely equal to or slightly higher than the production of the control. In the second case, fermentation of sugar beet extract at sucrose concentration 10 g/l was comparable to the fermentation on pure sucrose except that the hydrogen yield was slightly higher on sugar beet extract. In particular, hydrogen yields of 2.9 and 3.0 mol/mol hexose were determined in fermentations of sucrose and sugar beet extract, respectively, corresponding to 73% and 75% of the theoretical value of 4 mol hydrogen/mol hexose. Acetic acid was the main product and very low production of lactic acid was observed. (orig.)

    Visible and near-infrared spectra in interactance mode were acquired for intact and sliced beet samples, using two portable spectrometers for the spectral regions of 400-1100 nm and 900-1600 nm, respectively. Sucrose prediction models for intact and sliced beets were developed and then validated. The spectrometer for 400-1100 nm was able to predict the sucrose content with correlations of prediction (rp) of 0.80 and 0.88 and standard errors of prediction (SEPs) of 0.89% and 0.70%, for intact beets and beet slices, respectively. The spectrometer for 900-1600 nm had rp values of 0.74 and 0.88 and SEPs of 1.02% and 0.69% for intact beets and beet slices. These results showed the feasibility of using the portable spectrometer to predict the sucrose content of beet slices. Using simple correlation analysis, the study also identified important wavelengths that had strong correlation with the sucrose content. PMID:25148988

    An improved analytical method for the determination of geosmin in red beets was developed using headspace solid-phase microextraction (HSPME). Volatiles of beet juice were extracted in headspace for 2 h using a polydimethylsiloxane/divinylbenzene fiber, thermally desorbed from the fiber, and analyzed by gas chromatography. The HSPME method was determined to be suitable for geosmin analysis as evidenced by high relative recovery (99.2%), low relative standard deviation (7.48%), and reasonable detection limit (1 microg/kg of beet root tissue). The concentrations of geosmin in four beet cultivars ranged from 9.69 +/- 0.22 to 26.7 +/- 0.27 microg/kg, depending on cultivar. PMID:12568566

  8. Influence of radiation-induced free radicals on biological processes in sugar beets

    International Nuclear Information System (INIS)

    The electron spin resonance (E.S.R.) spectra of free radicals stabilized in the sugar beet seeds nave been investigated. Two types of radicals with different E.S.R. signal width (0.7 and 17.2 mT) have been observed. The yields of radicals increase with increase of the absorbed dose and with decrease of humidity of sugar beet seeds. The changes in dose rates does not affect the yield of radicals. The concentration of free radicals decreases exponentially if seeds have been kept in air atmosphere, but remains the same when seeds have been stored in closed vessels. Radiation stimulations of some new sugar beet seeds causes the increase of sugar amount in beet roots approximately by 4 cnt/ha. The results of microfield experiments indicate, that the best effect of stimulation can be reached by irradiation with dose of 100-200 Gy. (author)

  9. The ultrasound-assisted sugar extraction from sugar beet cossettes

    International Nuclear Information System (INIS)

    The aim of this work was to study the ultrasound-assisted water extraction of sugar from sugar beet cossettes. The ultrasound bath device (25 kHz, 200 W) was used. The sonication accelerated sugar diffusion at both temperatures 18 deg C and 77.6 deg C and gave the higher level of dry matter content SS (4-6 percent) and sugar content CK (7-22 percent) in juice. The SS and CK depended on time of exposition, time and temperature of extraction. In particular, the effects of 5 min ultrasound-assisted extraction were equal to 20 min extraction in traditional conditions. The shorter time, lower temperature, higher efficiency and purity of juice could be the effects of sugar extraction with ultrasound. The change of thickness of diffusion membrane, microflows in tissue as well as it's environment caused by ultrasound was the reason of acceleration of sugar extraction

  17. Sugar beet for bioethanol production: An approach based on environmental agricultural outputs

    International Nuclear Information System (INIS)

    The EU imports both bioethanol and the raw material needed to produce it. Thirty percent of bioethanol is produced from sugar beets in the EU. However, sugar beet cultivated area and yields have fallen due to the 2006 sugar regime reform. Given the potential uncertainty about the future for sugar beet farmers, biofuels may represent an alternative market. This paper analyses potential contribution to the efficiency, in terms of environmental output, of the sugar beet crop both when production is oriented toward bioethanol and regarding the use of input. An empirical application is performed in Spain by Data Envelopment Analysis (DEA). The results show that 4% of farms have full technical efficiency, while the rest have an average efficiency of 55.9%. The figures show that inputs can be reduced over 40%, and also show the low average level of input-use efficiency. In addition, it cannot be said that there is a relationship between efficiency and farm scale. The consideration of aspects such as the environmental advantages of using sugar beet production for bioethanol can open new lines of action to support this crop in the EU. In addition, boosting sugar beet production may reduce potential dependency on importation. - Highlights: ► Analysing environmental outputs from agricultural input use and production orientation to bioethanol. ► DEA is applied to model farms’ efficiency in GHG emission and nitrous oxides emissions. ► A very low level of efficiency is found in sugar beet farms. ► Efficiency increase should be supported to reduce fertilizers and pesticides. ► Environmental advantages of addressing sugar beet to bioethanol open new lines to support crops

  20. Potassium efficiency of wheat and sugar beet evaluated under field conditions

    International Nuclear Information System (INIS)

    This study was conducted to investigate the potassium (K) efficiency of wheat and sugar beet under field conditions and to identify the varying mechanisms or factors behind their efficiency. Data were obtained from a long term fertilizer experiment, on a K (fixing) sandy clay loam in Bavaria, southern Germany, in which K fertilization rates varied from 0 to 1000 kg K ha-1 year -1 with the last K application in 1986. In 2003, sugar beet and spring wheat were sown on March 13th and April 4th respectively. At 4 and 5 harvests for wheat and sugar beet, respectively, random samples of shoots, roots and soil of each species from the unfertilized (-K) and the highest fertilizer level of 1000 kg K ha-1 (+K) treatments were analyzed. Sugar beet and wheat had similar K efficiency producing 76% and 80% beet and grain yield on unfertilized compared with fertilized treatments, respectively. As compared to wheat, sugar beet had a higher internal K requirement, two times higher shoots growth rate (GRs), 34% to 48% of the wheat root length (RL), and consequently a larger GR/RL, that is higher demand for K uptake on the roots. However, sugar beet showed an exceptionally high uptake efficiency of the single roots or influx, which was 5 times higher in unfertilized treatments, as compared with wheat. Wheat K efficiency was attributed to a higher utilization efficiency or lower internal requirement, slow growing shoots and a large root system. Further investigations are necessary to study the mechanism by which sugar beet was able to achieve a higher influx than wheat.(Author)

    Full Text Available High yields with low costs require that sugar beets be kept free of weeds, during critical periods, using labor or chemical treatments. Since the critical periods for this crop in Castilla - La Mancha (Spain are unknown, the first goal of this study was to determine the effect of early and late competition on yield. The second goal was to determine the critical periods, while taking into consideration the semiarid climatic conditions of this region. Two irrigation farms located in the province of Albacete are dedicated to sugar beet cultivation. These two farms were chosen to carry out the tests March (140,000-150,000 seeds ∙ ha-1 and harvested in October. Two simultaneous and complementary experiments were carried out in each year and farm. Two scenarios were considered with eight different treatments each. In the first one (With Weeds Until - WWU, plots were infested by weeds up to a certain date. In the second one (Free of Weeds Until - FWU, plots were kept free of weeds up to a certain date. For each test, a randomised experimental blocked field was designed and there were four repetitions, each of them containing eight elemental plots (12 m2. Each plot was weeded by hand or weeds were left to grow till a definite date.The results indicated that a 1% loss of yield was reached in the early competition after 14 days, while a loss of 5% was reached after a period of 41 days after it was infested. The results also indicated that in late competition, if a crop is kept clean for 124 days and it is infested afterwards, a 1% loss is reached. However, the loss increases to 5% if the plot is kept clean for 111 days. For a 1% loss the critical period is 110 days and 70 days for a 5% loss.

    2014-03-01

    Full Text Available Common lambsquarters, cleavers, ladysthumb and wild buckwheat, chamomile, mercury, foolsparsleey and volunteer rapes are only some of the most important weeds in fooder and sugar beets. For the control of classical weed societies farmers can fall back on a limited number of active ingredients. Generally, Phenmedipham (PMP, Desmedipham (DMP and Ethofumesate are the basis of a spray sequence. They are complemented with other active ingredients depending on the specific weed situation. The newly formulated BELVEDERE® Extra combines the three mentioned active ingredients in an optimal ratio. Hence, the herbicide covers a very broad weed spectrum with an excellent efficacy on Common lambsquarters, cleavers, ladysthumb and wild buckwheat. BELVEDERE® EXTRA is a liquid, selective, and systemic herbicide. It is formulated as suspoemulsion so that a high efficacy is achieved while preserving a very good selectivity. The product allows for flexible control of leaf activity as an additive (e.g. OLEO FC is appended. Ethofumesate, which is mainly effective via the roots of the plant, belongs to a different HRAC group than Phenmedipham and Desmedipham. The high concentration of 200 g/L Ethofumesate leads to an effective resistance management especially regarding Fathen and other important weeds. Since 23rd of September 2013 BELVEDERE® extra is registered for post emergence splitting application (3 applications against annual dicotyledonous weeds. The maximum application rate per treatment is 1,3 L/ha. In combination with GOLTIX® TITAN® (Metamitron + Quinmerac or Goltix® Gold (Metamitron the weed spectrum is broadened. Basically, a timely application whose application rates are adapted to the location is essential for a good efficacy of beet herbicides.

    1994-05-01

    Recombinant genomes derived from the Logan and CFH strains of the geminivirus beet curly top virus (BCTV) have been constructed and analyzed for pathogenicity on Nicotiana benthamiana and sugar beet (Beta vulgaris L.). Infectivity assays indicated that the latent period on N. benthamiana was primarily determined by a DNA fragment bearing the leftward open reading frames (ORFs) L1, L2, L3, and L4. Recombinants bearing leftward ORFs from the CFH strain were characterized as having a short latent period (mean = 6-11 days), while the reciprocal recombinants bearing leftward ORFs from the Logan strain had latent periods defined as long (mean = 16-22 days). Infectivity assays on sugar beet indicated that certain recombinant BCTV genomes exhibited novel pathogenic properties not common to either wild type strain, including the loss of systemic movement and replication competency, or asymptomatic systemic infection of sugar beet. The results indicate that N. benthamiana is a more permissive host than sugar beet with respect to heterologous combinations of BCTV genes, and that pathogenicity and virulence of BCTV in sugar beet requires the interaction of certain viral gene products and/or cis-elements that have coevolved in the same strain.

  8. Life cycle analysis for bioethanol production from sugar beet crops in Greece

    International Nuclear Information System (INIS)

    The main aim of this study is to evaluate whether the potential transformation of the existing sugar plants of Northern Greece to modern bioethanol plants, using the existing cultivations of sugar beet, would be an environmentally sustainable decision. Using Life Cycle Inventory and Impact Assessment, all processes for bioethanol production from sugar beets were analyzed, quantitative data were collected and the environmental loads of the final product (bioethanol) and of each process were estimated. The final results of the environmental impact assessment are encouraging since bioethanol production gives better results than sugar production for the use of the same quantity of sugar beets. If the old sugar plants were transformed into modern bioethanol plants, the total reduction of the environmental load would be, at least, 32.6% and a reduction of more than 2 tons of CO2e/sugar beet of ha cultivation could be reached. Moreover bioethanol production was compared to conventional fuel (gasoline), as well as to other types of biofuels (biodiesel from Greek cultivations). - Highlights: → Bioethanol production gives better results than sugar production from sugar beets. → In most cases, sugar beets, as an already industrialized plant has organizational virtues. → Bioethanol could be a sustainable independent way of energy production, alternative to biodiesel.

  9. Some remarks on evaluation of drying models of red beet particles

    International Nuclear Information System (INIS)

    Drying behaviour of red beet particles was investigated in a laboratory type dryer, at constant air velocity 1 m/s and at constant temperature 60 deg. C. The effect of initial material load, particle shape and size on the dehydration characteristics of red beet was investigated. The drying experiments were conducted at three levels of initial material load of 5.33, 10.67 and 16 kg/m2. The following particle shapes were investigated: slices, cubes, and prisms. Red beet roots were cut into 3, 6 and 9 mm slice thickness, 6, 9 and 12 mm cube thickness, and 3, 6 and 9 mm prisms thickness. Length of square based prisms equalled 50 mm. The results have shown that, the initial material load, particle shape and size influence on the drying behaviour of red beet particles. The experimental dehydration data of red beet particles obtained were fitted to the semi-theoretical, empirical and theoretical models. The accuracies of the models were measured using the correlation coefficient (R), mean bias error (MBE), root mean square error (RMSE), reduced chi-square (χ2), and t-statistic method. All models except that used by Wang and Singh described the drying characteristics of red beet particles satisfactorily. The effect of the characteristic dimension of the particle and initial material load on the drying models parameters were also determined.

    Full Text Available Isuluies of Rhizoctonia cerealis anastomosis group GAG-1 were obtained from sharp eyespot lesions on wheat and on barley culms and from diseased sugar beet seedlings. Isolates of R. cerealis were collected from a fields with crop rotation experiments: sugar beet-spring wheat-winter barley. In pathogenicity tests isolates of R. cerealis from sugar beet seedlings and from sharp eyespot lesions on wheat and barley were pathogenic to these crops. Isolates of R. cerealis from sharp eyespot lesions on wheat and barley caused severe damping-ofTof sugar beet. Isolates of R. cerealis from sugar beet seedlings also caused symptoms of sharp eyespot on wheat and barley. None of the wheat and barley isolates of R. cerealis tested caused root-rot on wheat or barley seedlings. Isolates of R. cerealis obtained from diseased plants of wheat, barley and sugar beet were similar in morphology of cultures and anastomosed with GAG-1 tester isolate. The relatinoship between anastomosis. colony characters, growth rate, hyphal diameter and pathogenicity of AG-4. AG-2-2 and AG-5 isolates obtained together with R. cerealis from diseased plants were also investigated.

    Kimberly M. Webb

    2014-04-01

    Full Text Available Rhizomania, caused by Beet necrotic yellow vein virus (BNYVV, severely impacts sugar beet (Beta vulgaris production throughout the world, and is widely prevalent in most production regions. Initial efforts to characterize proteome changes focused primarily on identifying putative host factors that elicit resistant interactions with BNYVV, but as resistance breaking strains become more prevalent, effective disease control strategies will require the application of novel methods based on better understanding of disease susceptibility and symptom development. Herein, proteomic profiling was conducted on susceptible sugar beet, infected with two strains of BNYVV, to clarify the types of proteins prevalent during compatible virus-host plant interactions. Total protein was extracted from sugar beet leaf tissue infected with BNYVV, quantified, and analyzed by mass spectrometry. A total of 203 proteins were confidently identified, with a predominance of proteins associated with photosynthesis and energy, metabolism, and response to stimulus. Many proteins identified in this study are typically associated with systemic acquired resistance and general plant defense responses. These results expand on relatively limited proteomic data available for sugar beet and provide the ground work for additional studies focused on understanding the interaction of BNYVV with sugar beet.

    Full Text Available Ground cherry (Physalis divaricata L. is one of the most important summer weeds in sugar beet crop in the west of Iran. In order to estimate the damage rate of this weed, field studies were conducted to quantify the effect of ground cherry density on sugar beet yield and to determine relationships among different weed densities (0, 0.5, 1, 2, 4, 8 and 16 plants m-2 and sugar beet yield in 2008. The experiment design was randomized complete blocks with three replications. In addition, the neighborhood effect of ground cherry was assessed in a completely randomized design. Neighborhood effect was surveyed from zero to 125 cm apart from each beet plant to ground cherry. Density of ground cherry was estimated as the systematic method in 30 sugar beet fields that were chosen randomly.Phonology of ground cherry was recorded based on the GDD (Growth Degree Day and date. Results showed that two weed plants m2 of this weed resulted in 34% damage to sugar beet. Ground cherry significantly reduced yield of sugar beet when sown 50 cm apart from crop plant. Crop damage of sugar beet was 41% when ground cherry seeds were sown at zero cm apart from each sugar beet plant. Flowering of ground cherry occurred in the middle of June when it received 61.45-75 GDD and it was distinguished that ground cherry is a neutralized weed to the long day.

  15. The economic feasibility of sugar beet biofuel production in central North Dakota

    International Nuclear Information System (INIS)

    This study examines the financial feasibility of producing ethanol biofuel from sugar beets in central North Dakota. Under the Energy Independence and Security Act (EISA) of 2007, biofuel from sugar beets uniquely qualifies as an 'advanced biofuel'. EISA mandates production of 21 billion gallons of advanced biofuels annually by 2022. A stochastic simulation financial model was calibrated with irrigated sugar beet data from central North Dakota to determine economic feasibility and risks of production for 0.038 hm3y-1 (or 10 MGY (Million Gallon per Year) and 0.076 hm3y-1 (or 20 MGY) ethanol plants. Study results indicate that feedstock costs, which include sugar beets and beet molasses, account for more than 70 percent of total production expenses. The estimated breakeven ethanol price for the 0.076 hm3y-1 plant is $400 m-3 ($1.52 per gallon) and $450 m-3 ($1.71 per gallon) for the 0.038 hm3y-1 plant. Breakeven prices for feedstocks are also estimated and show that the 0.076 hm3y-1 plant can tolerate greater ethanol and feedstock price risks than the 0.038 hm3y-1 plant. Our results also show that one of the most important factors that affect investment success is the price of ethanol. At an ethanol price of $484.21 m-3 ($1.84 per gallon), and assuming other factors remain unchanged, the estimated net present value (NPV) for the 0.076 hm3y-1 plant is $41.54 million. By comparison, the estimated NPV for the 0.038 hm3y-1 plant is only $8.30 million. Other factors such as changes in prices of co-products and utilities have a relatively minor effect on investment viability. -- Highlights: → Sugar beets and beet molasses costs account for more than 70 percent of total production expenses. → The estimated breakeven ethanol prices for the 0.076 hm3y-1 and 0.038 hm3y-1ethanol plants are $400 m-3 and $450 m-3 respectively. → The price of ethanol will be one of the most important factors for determining the future feasibility of a sugar-beet-based ethanol plant in North

    Full Text Available The article presents results of research of quality, safety and content of biologically active substances of food red beet roots of Bordo 237 variety, grown in the Krasnodar region in 2014. On the basis of the research carried out it was established, that there are carbohydrates, proteins, organic acids and mineral substances in the food red beet roots of Bordo 237 variety. Food red beet roots are a source of dietary fibers (pectin, protopectin, hemicelluloses and cellulose, possessing antitoxic, antioxidant, radiation protective, cholesterol-lowering and lipid correcting qualities, and also a source of vitamins C, B9 (folic acid and P-active substances, possessing antioxidant properties. Due to high content in food red beet of a complex of microelements – iron, zinc, manganese and copper, and a complex of macro elements – potassium and magnesium, it can be recommended for prophylaxis and treatment of hypertension, atherosclerosis and other diseases of heart and vascular system, and for prophylaxis of iron-deficiency anemia. Thus, the research of quality, safety and content of biologically active substances showed that food red beet roots of Bordo 237 variety are a high quality component ingredient for creation of food products of specialized and functional purpose

  17. Phloem unloading in developing leaves of sugar beet

    International Nuclear Information System (INIS)

    Physiological and transport data support a symplastic pathway for phloem unloading in developing leaves of sugar beet (Beta vulgaris L. Klein E, multigerm). The sulfhydryl inhibitor parachloromercuribenzene sulfonic acid (PCMBS) inhibited uptake of [14C]-sucrose added to the free space of developing leaves, but did not affect import of [14C]-sucrose during steady-state 14CO2 labeling of a source leaf. The passively-transported xenobiotic sugar, [14C]-L-glucose did not readily enter mesophyll cells when supplied through the cut end of the petiole of a sink leaf as determined by whole leaf autoradiography. In contrast, [14C]-L-glucose translocated through the phloem from a mature leaf, rapidly entered mesophyll cells, and was evenly distributed between mesophyll and veins. Autoradiographs of developing leaves following a pulse of 14CO2 to a source leaf revealed rapid passage of phloem translocated into progressively higher order veins as the leaf developed. Entry into V order veins occurred during the last stage of import through the phloem. Import into developing leaves was inhibited by glyphosate (N-phosphomethylglycine), a herbicide which inhibits the aromatic amino acid pathway and hence protein synthesis. Glyphosate also stopped net starch accumulation in sprayed mature leaves, but did not affect export of carbon from treated leaves during the time period that import into developed leaves was inhibited

    Full Text Available The additive of acceptable sensory, physical and chemical and microbiological characteristics was made from cossettes. Great water binding capacity related to microcrystals of cellulose qualifies this additive as a desired one in bread making process. Bread was baked in the laboratory and patent flour was used. The additive with particles smaller than 95 (m was supplemented in the quantities of 2, 5 and 10%. The data related to the influence of the quantity of additive on white bread quality point that parallel to increasing the amount of the additive in the dough, yield of dough and bread were also increased. Negative effects are detected as volume depression and inferior bread crumb quality and altered crumb color. The decrease in bread quality is small if 2% of additive was applied, but significant with 5 and 10%. The bread freshness was highly graded 48 hours after baking due to the ability of the additive to retain water. On the whole, bread of superior quality supplemented by 5 and 10% of the additive from sugar beet fiber can be easily made by fortifying flour with gluten and by adding appropriate dough conditioner.

    Cane molasses, most of which is imported, is used as a raw material for production of baker's yeast (Saccharomyces cerevisiae) in Japan. On the other hand, beet molasses is scarcely used for this purpose, but it can be of great advantage to cane molasses because it is domestically produced in relatively high amounts as a by-product of beet sugar processing. However, the yield of baker's yeast is sometimes low with Japanese beet molasses compared to imported cane molasses. For the production of baker's yeast with Japanese beet molasses, we evaluated S. cerevisiae strains, including industrial and laboratory strains, to group them according to the growth profile on beet and cane molasses. To discuss the factors affecting growth, we further analyzed the major compounds in both types of molasses. Beet molasses seems to contain compounds that promote the growth of beet molasses-favoring strains rather than inhibit the growth of cane molasses-favoring strains. It was assumed that α-amino acid was one of the growth promotion factors for beet molasses-favoring strains. PMID:24333188

    2005-01-01

    We have carried out comparative studies of double-stranded RNA (dsRNA) of viral nature isolated from sugar beet leaves and from mycelium of microscopic fungi using different methods such as PAAG electrophoresis and by polymerase chain reaction (PCR). It was shown that the fragments of dsRNA from sugar beet leaves and from mycelium microscopic fungi had the identical electrophoretic pattern and the same size (1.8 and 2.0 kbp). Using PCR technique it was shown, that isolated dsRNA have a common template for amplification. Electron microscopy of PCR-positive mycelium allows us to detect the virus particles of the spherical form with diameter 30-40 nm. The obtained data confirm our previous suppositions, concerning the belonging of isolated dsRNAs (size 1.8 and 2.0 kbp) to new mycovirus targeted a microscopic fungus, instead of beet cryptic viruses.

    Full Text Available This study was conducted to identify the optimal method of sugar beet (Beta vulgaris var. saccharifera seed sterilization to "in vitro" cultures initiation, and to found a cultivar that is suitable to growth in specific conditions of vitroculture. The study was necessary because the literature does not refer to the method of initiating vitrocultures from encapsulated beet seeds and to avoid any losses that may occur in a massive micropropagation. The most optimal method for beet encapsulated seeds asepsization, prior inoculation on the vitroculture medium consists in the their dipping in sodium hypochlorite solution for 15 minutes, and the best cultivar which was suited to micropropagation was Evelina, but Diamant too, with 90 - 95% germination rate and a very good ulterior growth.

  9. Selection of sugar-beet calli to obtain plants resistant to Cercospora beticola

    International Nuclear Information System (INIS)

    The classic double-layer technique used in microbiology was tentatively adapted to select sugar-beet calli resistant to different toxins of Cercospora beticola. For this purpose, calli were placed on a culture medium containing benomyl, which was poured on the C. beticola culture. Among the different fungal species studied (C. musae, C. medicaginis, C. carotae and C. beticola), only C. beticola and C. carotae induced a toxic effect, which was unrelated to the ability of the fungal strains to produce the known toxins cercosporin and/or C. beticola toxin. The toxic preparation, which causes the death of beet calli, also induced a loss of electrolytes from sugar-beet leaf discs. (author)

    The omission of malt provides for different values of the viscosity in the wort. Various concentrations of the worts obtained this way were fermented to EtOH, and the important parameters, such as yeast cell count, acidity, EtOH assay, unfermented sugars, etc. were determined. Yeasts cultivated on beet worts under addition of (NH/sub 4/)/sub 2/SO/sub 4/, H/sub 3/PO/sub 4/, K/sub 2/CO/sub 3/, and MgSO/sub 4/, will easily ferment sugar beet worts under technical conditions to acceptable EtOH values of 11.1 dl EtOH/long ton of beets. This method was used in a plant continuously for 3 years, saving 200 long tons malt/year.

    Full Text Available During 2002-2004, field surveys of field dodder (Cuscuta campestris Yunck e r in croplands were done in southwestern Slovakia. From among 150 localities surveyed, 80 were found infested by the field dodder. Within crop plants, C. campestris infested sugar beet (Beta vulgaris, alfalfa (Medicago sativa tobacco (Nicotiana tabacum, potato (Solanum tuberosum, lentil (Lens esculenta, parsley (Pastinaca sativa and onion (Allium cepa. Besides the crops, 18 weed species were also recorded. The species from the genus Polygonum (Polygonaceae were the most important and acted as a significant reservoir of field dodder in cropland. C. campestris was not found in cold climatic regions with altitude higher than 240 m. The impact of field dodder infestation on sugar beet yield was studied during the year of 2004 in two localities (Šalov and Žitavce in southwestern Slovakia. The presence of field dodder markedly reduced both, quantity and quality of sugar beet yield. Weight of heavily infested beets was reduced from 21.6 to 37.4% and sugar content from 12.0 to 15.2%. Such decline of both parameters was also recorded when field dodder was removed together with leaves of sugar beet during growing season at the end of July. The aim of the infested leaves removal was to decrease mass of field dodder seeds. Although the leaf area of sugar beet regenerates, the decrease of quality and quantity was observed. The decline was the same at both localities, no matter whether the fields were irrigated (Šalov or not (Žitavce.

    2013-09-01

    Full Text Available The sugar beet weevil, Lixus incanescens B., is one of the most important pests of sugar beet plant in Iran. The petioles and leaves of sugar beet are attacked by larvae and adults of the sugar beet weevil. Chemical application is currently used for controlling the pest. Digestion in the alimentary canal of the sugar beet weevil is facilitated by some carbohydrases. Results of the in vitro studies indicated the presence of alpha-amylase, beta-glucosidase and beta-galactosidase in the digestive tract of the pest. Highest activities of alpha-amylase, beta-glucosidase and beta-galactosidase were at pH 5, pH 5 and pH 4, respectively. No significant alpha-glucosidase and alpha-galactosidase activity was detected in the pest's digestive system. Optimum temperatures for alpha-amylase, beta-glucosidase and beta-galactosidase activity were determined at 45, 50 and 40 oC, respectively. alpha-amylase was more stable under acidic condition (pH 4 to pH 6 than under highly acidic and alkaline condition. Na+ and K+ increased alpha-amylase activity, but sodium dodecyl sulfate significantly decreased amylase activity. Also, the activity of alpha-amylase was inhibited by the other compounds such as MgCl2, CaCl2 and EDTA. Zymogram analysis using native-PAGE revealed one band of alpha-amylase activity in Lixus incanescens. High activity of carbohydrases in the digestive system of adults was determined and further researches are needed to be applied to design new strategies for controlling the sugar beet weevil based on natural carbohydrase inhibitors.

    International Nuclear Information System (INIS)

    Changes in functional properties of pectin extracted from sugar beet or citrus peel by electron beam in solid state or aqueous solution were investigated. Citrus pectin (CP) was degraded at both solid state and aqueous solution by irradiation with electron beam. Sugar beet pectin (SBP) was degraded at solid state but in aqueous solution at high concentrate was polymerized by irradiation with electron beam. SBP polymerized by electron beam formed hydrogel. This hydrophilic polymer was useful as water absorbent. Moreover, it was confirmed that the emulsification stability and acidified milk beverage stabilization of SBP was enhanced by electron beam.

    2003-12-01

    Full Text Available In Hungary, the sugar beet production suffers from many complex factors, which reflect on a crisis situation. Due to the narrowing markets and a decrease in the demands for sugar all together with the uncertainty and over-production of the processing industry, the sugar beet producers are very defenceless. The special technology of the sugar beet production gives an especial importance to this fact. There is not too much place fo changes for the farmers within the structure of the production costs, which has consequences in terms of both quality and volume. In the European Union, the sugar sector is highly regulated. The accession will lead us to a decades-old and solid state of the sugar production. For all member countries, unique and harmonised prices and export regulations exist. With the accession, the EU countries have the opportunity to target the markets of the newly joining countries, such as Hungary, with their surplus in sugar production. Therefore, it is in their interest to give as low quota as possible to the Hungarian sugar beet production.One key point of the regulations of the sugar production is the quota and its introduction in the production. For this reason and for the functioning CMO.s of the sugar beet sector, it is important to create and maintain an accurate and up-to-date database and the relating institutional background. The statistical and information system should cover - besides the data of the domestic production and processing and the international trade- the monitoring of the foreign markets and the whole of the agribusiness. The effectiveness of the production should improve even if a number of the farmers have to give up beet production. It is in significant the government´s responsibility to ensure these farmers´ safety of existence. By the time of the accession, reaching an average yield of 45 to 55 tons per hectare, the Hungarian sugar beet production will be competitive with the EU farmers. The current

    It is well known that molasses stillage is difficult to dry because of its high hygroscopicity. This investigation was made to try to affect the drying capacity of beet molasses stillage by the addition of gelling agents. Increase in crude protein and essential amino acid content of beet molasses was obtained by growing Brevibacterium flavum and Candida utilis. The results obtained showed that drying performance is probably due to an optimum combination of the chemico-physical properties of the raw material. 7 references.

    Emissions of greenhouse gases such as CO2, CO, CH4 and NOX from fossil fuel use are implicated in climate change. The use of bioethanol is one means to reduce fossil fuel use and emissions of greenhouse gases. This study investigated research to produce ethanol from sugar beet and use as fuel in Turkey. The calculated demand for bioethanol amounted to some 220,000 m3 where a 5% ethanol mix in petrol was used. Turkey has the potential to produce 30 million ton of sugar beet, which is sufficient to meet the bioethanol demand

    In a joined research project of several companies a procedure for conservation of sugar beet was developed. Model experiments were carried out for this purpose. The conception of the procedure tested was the ensiling of whole sugar beets in large plastic bags, after the surface of the individual beets is treated with an antimycotic preservative. Chopping of the beets is done after the storage in the bags. In the course of these experiments, a method was developed and tested which enables the determination of the conservation losses expressed as losses of the methane forming potential. This method is also suitable to evaluate other procedures of sugar beet conservation and storage. (orig.)

  5. Cold-inhibited phloem translocation in sugar beet

    International Nuclear Information System (INIS)

    Experimental studies were undertaken on a simplified single source leaf-single sink leaf, or single source leaf-double sink leaf sugar beet system to investigate the responsive nature of the long-distance phloem translocation system to localized cooling perturbations on the source leaf petiole. Experiments were performed by using a steady state [14C]-labelling system for the source leaf, and translocation into the sink leaf (leaves) was monitored with a Geiger-Mueller system. A specially designed Peltier apparatus enabled cooling of the source petiole to 10C (or other desired temperatures) at various positions on the petiole, over different lengths, and at different rates of cooling. Initial experiment were designed to test the predictions of a mathematical recovery model of translocation inhibited by cold. The results did not support the mathematical model, but did suggest that vascular anastomoses may be involved in the recovery response. Selective petiolar incision/excision experiments showed that anastomoses were capable of re-establishing translocation following a disruption of flow. Studies with two monitored sink levels suggested that the inhibition to slow-coolings was not due to reduced translocation through the cooled source petiole region, but rather, was due to a repartitioning of flow among the terminal sinks (sink leaves and hypocotyl/crown region above the heat-girdled root). This repartitioning occurred via a redirection of flow through the vascular connections in the crown region of the plant, and appeared to be promoted by rapid, physical signals originating from the cooled region of the petiole

    Full Text Available Growing demand for better quality and cheaper products put on the need to industry to balance between the two kinds of needs, which are the reduction of production costs and to ensure a high quality product. This is the case with dried sugar beet pulp as a byproduct of sugar refining process. One of the possibilities to reduce energy consumption is savings in the process of thermal dehydration in the process of the conventional drying of pulp. Pulp drying is one third of total energy consumption in the sugar factory. Acidification of water extraction result in pulp that could be pressed better and in other hand in the juice with less non-sucrose compounds. Keeping the extraction process under certain conditions, directly affects on the quality of the extracted pulp and on effects of their further processing. This paper examines the impact of the extraction parameters of sugar from sugar beet and agents of acidification for water extraction (sulphurous acid, hydrogen peroxide on the quality of dried sugar beet pulp. Extraction of sugar from sugar beet cossettes by hydrogen peroxide at pH 5.5 to 8.5 does not cause changes in mechanical properties of sugar beet cossettes and in water retention coefficient, but increases the brightness of dried sugar beet pulp for about 5-7 units, which solubility in water does not depend on the applied concentration of extracting agents, but increases in dependence on the duration of the extraction. Sugar beet pulp extracted at pH 11.0 has reduced strength, they are highly hydrated, and under the force they lose their shape, binding a larger amount of water thus reducing the effect of their pressing. The changes in microstructure were probably accompanied by segmenting the linear parts of macromolecules and are reflected in the increase of water retention capacity and increase the solubility of dried sugar beet pulp for two to three times. Under the same conditions of extraction, sulphurous acid produces similar

    The maize Activator/Dissociation (Ac/Ds) transposable element system was introduced into sugar beet. The autonomous Ac and non-autonomous Ds element excise from the T-DNA vector and integrate at novel positions in the sugar beet genome. Ac and Ds excisions generate footprints in the donor T-DNA that support the hairpin model for transposon excision. Two complete integration events into genomic sugar beet DNA were obtained by IPCR. Integration of Ac leads to an eight bp duplication, while integration of Ds in a homologue of a sugar beet flowering locus gene did not induce a duplication. The molecular structure of the target site indicates Ds integration into a double strand break. Analyses of transposase transcription using RT-PCR revealed low amounts of alternatively spliced mRNAs. The fourth intron of the transposase was found to be partially misspliced. Four different splice products were identified. In addition, the second and third exon were found to harbour two and three novel introns, respectively. These utilize each the same splice donor but several alternative splice acceptor sites. Using the SplicePredictor online tool, one of the two introns within exon two is predicted to be efficiently spliced in maize. Most interestingly, splicing of this intron together with the four major introns of Ac would generate a transposase that lacks the DNA binding domain and two of its three nuclear localization signals, but still harbours the dimerization domain.

    This study analyzed the effect of three levels of drip irrigation in sugar beet (Beta vulgaris L.) production in the Middle Anatolian region of Turkey. Two deficit irrigation treatments 75% and 50% of measured soil water depletion were compared with a full irrigation control treatment. In this paper, root yield, NEY (net energy yield), EEP (efficiency of energy production) and EWUE (energy water use efficiency) were investigated. Energy consumption of irrigation was found to be about 60% of total energy input in sugar beet production under full and deficit irrigation treatments. It was found that sugar beet had the highest EEP value (6.29) under the partial deficit irrigation (representing 75% of full irrigation). However, it was observed that full and severe deficit irrigation (representing 50% of full irrigation) treatments had a lower value. Results of this study indicated that the partial deficit drip irrigation technique can be applied in sugar beet production. In practice, deficit irrigation technique can reduce irrigation water use up to 25% compared to full irrigation technique. In addition, partial deficit drip irrigation technique may save 11.2% of total energy inputs, 16.1% of irrigation energy inputs, 21.2% of total fuel use and 25% of fuel use in irrigation. (author)

    Two biochars were produced from anaerobically digested and undigested sugar beet tailings through slow-pyrolysis at 600°C. The digested sugar beet tailing biochar (DSTC) and raw sugar beet tailing biochar (STC) yields were around 45.5% and 36.3% of initial dry weight, respectively. Compared to STC, DSTC had similar pH and surface functional groups, but higher surface area, and its surface was less negatively charged. SEM-EDS and XRD analyses showed that colloidal and nano-sized periclase (MgO) was presented on the surface of DSTC. Laboratory adsorption experiments were conducted to assess the phosphate removal ability of the two biochars, an activated carbon (AC), and three Fe-modified biochar/AC adsorbents. The DSTC showed the highest phosphate removal ability with a removal rate around 73%. Our results suggest that anaerobically digested sugar beet tailings can be used as feedstock materials to produce high quality biochars, which could be used as adsorbents to reclaim phosphate.

    2016-05-01

    Rhizoctonia root and crown rot is an important disease problem in sugar beet caused by Rhizoctonia solani and also shown to be associated with Leuconostoc spp. Initial Leuconostoc studies were conducted with only a few isolates and the relationship of Leuconostoc with R. solani is poorly understood; therefore, a more thorough investigation was conducted. In total, 203 Leuconostoc isolates were collected from recently harvested sugar beet roots in southern Idaho and southeastern Oregon during 2010 and 2012: 88 and 85% Leuconostoc mesenteroides, 6 and 15% L. pseudomesenteroides, 2 and 0% L. kimchi, and 4 and 0% unrecognized Leuconostoc spp., respectively. Based on 16S ribosomal RNA sequencing, haplotype 11 (L. mesenteroides isolates) comprised 68 to 70% of the isolates in both years. In pathogenicity field studies with commercial sugar beet 'B-7', all Leuconostoc isolates caused more rot (P solani than when inoculated alone in both years. Also, 46 of the 52 combination treatments over the 2 years had significantly more rot (P solani are present in sugar beet roots. PMID:26735061

    2003-12-01

    One key point of the regulations of the sugar production is the quota and its introduction in the production. For this reason and for the functioning CMO.s of the sugar beet sector, it is important to create and maintain an accurate and up-to-date database and the relating institutional background. The statistical and information system should cover - besides the data of the domestic production and processing and the international trade- the monitoring of the foreign markets and the whole of the agribusiness. The effectiveness of the production should improve even if a number of the farmers have to give up beet production. It is in significant the government´s responsibility to ensure these farmers´ safety of existence. By the time of the accession, reaching an average yield of 45 to 55 tons per hectare, the Hungarian sugar beet production will be competitive with the EU farmers. The current technical and agronomical level of the whole sector does not satisfy the EU requirements, however a number of producers are falling into line with the EU level. Another task is to improve the effectiveness of the processing plants that could lead to the elimination of the factories with small capacity. In that case, additional attention should be paid on the sugar beet farmers and alternatives should be offered by the winding up concerns.

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, Sweden hereafter referred to as the evaluating Member State (EMS, received an application from DuPont Sverige AB to modify the MRL at the value of 0.015 mg/kg for the active substance picoxystrobin in sugar beet roots. In order to accommodate for the intended use of picoxystrobin Sweden proposed to raise the MRL from 0.01 mg/kg to the proposed MRL of 0.015 mg/kg. Sweden drafted an evaluation report in accordance with Article 8 of Regulation (EC No 396/2005, which was submitted to the European Commission and forwarded to EFSA. According to EFSA the data are sufficient to derive a MRL proposal of 0.015 mg/kg for the proposed use on sugar beet roots. Adequate analytical enforcement methods are available to control the residues of picoxystrobin in sugar beets . Based on the risk assessment results, EFSA concludes that the intended use of picoxystrobin on sugar beet roots will not result in a consumer exposure exceeding the toxicological reference value and therefore is unlikely to pose a public health risk.

  6. Effect of Irrigation Methods, Nitrogen and Phosphorus Fertilizer Rates on Sugar Beet Yield and Quality

    International Nuclear Information System (INIS)

    The experiment was conducted at a research station near Adlib. Two irrigation methods, sprinkler irrigation and drip fertigation, two phosphorus rates and four nitrogen rates 0, 70, 140 and 210 kg N/ha were tested. All N fertilizers were injected for drip irrigation or broadcasted for the sprinkler-irrigated treatments in six equally split applications. Neutron probe Results revealed that the introduction of drip fertigation was not proved to be a water saving relative to sprinkler irrigation. Dry matter production was slightly increased for the drip-fertigated treatments relative to sprinkler irrigated treatments. Nitrogen use efficiency was not improved under drip fertigation relative to that of sprinkler irrigation. Application of phosphorus fertilizer improved sugar beet yield as well as N uptake. No significant differences in sugar beet yield were observed due to the application of N fertilizer under drip fertigation. On the other hand, there was a trend toward increasing sugar beet yield grown under sprinkler irrigation. Drip fertigation had no negative effects on sugar content and other related properties, furthermore some of those properties were enhanced due to the employment of drip fertigation. Field water-use efficiency followed a similar trend and was increased under sprinkler irrigation relative to drip-fertigation for sugar beet yield parameter.

    Response surface methodology was used to optimise experimental conditions for ultrasonic-assisted extraction (UAE) of functional components from sugar beet molasses. The central composite design (CCD) was used for the optimisation of extraction parameters in terms of total phenolic contents, antioxidant activities and anthocyanins. Result suggested the optimal conditions obtained by RSM for UAE from sugar beet molasses were as follows: HCl concentration 1.55-1.72 mol/L, ethanol concentration 57-63% (v/v), extraction temperature 41-48 °C, and extraction time 66-73 min. In the optimal conditions, the experimental total phenolic contents were 17.36 mg GAE/100mL, antioxidant activity was 16.66 mg TE/g, and total anthocyanins were 31.81 mg/100g of the sugar beet molasses extract, which were well matched the predicted values. Teen compounds, i.e. gallic acid, vanillin, hydroxybenzoic acid, syringic acid, cyanidin-3-O-rutinoside, cyanidin-3-O-glucoside, catechin, delphinidin-3-O-rutinoside, delphinidin-3-O-glucuronide and ferulic acid were determined by HPLC-DAD-MS/MS in sugar beet molasses.

    2014-02-01

    Full Text Available The article considers main methodical approaches to formation of information support in management of production of sugar beet. It conducts analysis, systematisation and generalisation of theoretical developments of scientists with respect to definition of the “information support” notion, which allows formulation of the author’s vision. The article considers definitions of the expenditures notion as one of the central categories in management of production and types of cost value as objects of management. The article proves that business accounting is in close connection with the managerial system, which, consequently, determines a specific role of expenditures in enterprise management. It identifies topical directions of formation of information support in management of production of sugar beet. On the basis of the study of practice of sugar growing enterprises the article forms main data carriers within stages of the accounting process with the aim to carry out efficient management of sugar beet production. The prospect of further studies is improvement of information support in the beet growing industry through: development of accounting policy; system of primary documents by means of formation of product quality indicators; automation of formation of their indicators with the purpose of operative control; development of budgets for planning production indicators with the purpose of management and control.

    2014-01-01

    Although it is less studied than the white beet cyst nematode (Heterodera schachtii), the yellow beet cyst nematode (H. betae) has been found in many countries in Europe. For example in The Netherlands, France and Spain. H. betae causes yield losses on sandy soils. A high infestation can result in loss of complete plants. In The Netherlands, this nematode is especially found in the south eastern and north eastern part, where it occurs on 18% and 5% of the fields, respectively. From a project of the Dutch Sugar beet Research Institute IRS (SUSY) on factors explaining differences in sugar yield, this nematode was one of the most important factors reducing sugar yields on sandy soils. Until 2008, the only way to control H. betae was by reducing the number of host crops in the crop rotation. Host crops are crops belonging to the families of Cruciferae, Chenopodiaceae, Polygonaceae, Caryophyllaceae and Leguminosea. In order to find more control measures, research was done to investigate the host status of different green manure crops and the resistance and tolerance of different sugar beet varieties to H. betae. White mustard (Sinapis alba) and oil seed radish (Raphanus sativus spp. oleiferus) varieties resistant to H. schachtii were investigated for their resistance against H. betae. A climate room trial and a field trial with white mustard and oil seed radish were conducted in 2007 and 2008, respectively. Results show that H. betae could multiply on susceptible white mustard and susceptible oil seed radish, but not on the H. schachtii resistant varieties. In climate room trials in 2009, 2010 and 2011 and field trials in 2010, 2011 and 2012, the effect of different sugar beet varieties on the multiplication of H. betae and the effect of H. betae on yield at different infestation levels was investigated. Sugar beet varieties with resistance genes to H. schachtii (from Beta procumbens or B. maritima) were selected. Varieties with resistance genes from these sources were

    Full Text Available It was found that triazine herbicides exerted, when applied for a longer time, an increasing inhibitory effect on dry and fresh weight yields, transpiration and growth of the seedlings of flax, beet and buckwheat. At the same time enhanced accumulation of free amino acids and decrease of simple sugar values was noted in the aboveground parts of the test plants. The results are interpreted as the secondary effects of the inhibitory action of triazines on plant photosynthesis. The toxicity of the tested chemicals to flax, beet and buckwheat decreased in the following order: atrazine, simazine, propazine, atratone, prometone and prometryne. Flax was more resistant to triazines than beets and buckwheat.

    Red beet (Beta vulgaris L.) is a traditional and popular vegetable distributed in many part of the world and has been used as a natural colorant in many dairy products, beverages, candies and cattle products. Red beet roots contain two groups of betalain pigments, redviolet betacyanins and yellow betaxanthins. Betalains possess several biological activities such as antioxidant, anti-inflammatory, hepatoprotective, and anticancer properities. Recent trend of using natural products in industries tends toward multifunctional, high quality, and highpriced value foods and cosmetics. To meet the needs of consumers, cosmetics, medicine, and foods should contain the proper amount of natural products. Although the color removal processes such as filtration and absorption by clay are still useful, these procedures are difficult, time-consuming and costly. To overcome this problem, the radiation technology has emerged as a new way. Radiation technology has been applied to the decomposition and decoloration of pigment and is an efficient technique for inactivating pathogens, removing undesirable color in biomaterial extracts and improving or maintaining biological activities. Gamma-irradiation and electron beamirradiation techniques in previous reports were applied in order to remove any undesirable color and to improve or maintain biological activities of various extracts such as green tea leaves, licorice root, and S. chinensis fruits. Latorre et al. reported that betacyanin concentration decreased with the irradiation dose and significantly, in 35%, after 2.0 kGy of gamma-ray, whereas betaxathin concentration increased (about 11%-ratio with respect to control) after 1 kGy but decreased (about 19%) after 2 kGy. However, they did not try to analysis for completed removal of red beet pigments. Therefore, it is necessary to find the optimum irradiation dose for entirely removing red pigments in red beet.

    Balgheim, Natalie

    2016-02-01

    Full Text Available CONVISO SMART is a new system to control monocotyledonous and dicotyledonous weeds in ALS-inhibitor tolerant sugar beets. This system consists of an ALS-inhibiting herbicide and a sugar beet variety which is tolerant against the complementary herbicide due to classic breeding mechanisms. The herbicide CONVISO is a combination of the two active ingredients foramsulfuron and thiencarbazonemethyl. Whereas foramsulfuron is the leaf active compound, thiencarbazone-methyl is leaf as well as soil active. The product will be formulated as an oily dispersion (OD. The registration was requested with an application rate of 1 x 1 l/ha or 2 x 0.5 l/ha in ALS-inhibitor tolerant sugar beets. Application should be done from BBCH 10 – 14 of the weeds, especially of Chenopodium album as well as from BBCH 12 – 18 of the sugar beet. The estimated introduction of this system on the German market will be 2018. CONVISO is well active against the most important weeds in sugar beets, including Polygonum and Chenopodium species. Furthermore several difficult to control weeds as Aethusa cynapium and Mercurialis annua will be controlled by CONVISO. The addition of special herbicides to control those difficult weeds will no longer be necessary. The tolerance of the variety against CONVISO is very strong, which will be shown by the results of the weed free selectivity trials. Due to the high tolerance of the variety against CONVISO and the not occurring of negative herbicide effects, the full yield potential can be utilized.

  4. The practice of the direct isotopic dilution method of determining the sucrose content in sugar beet digestion liquids

    International Nuclear Information System (INIS)

    In order to determine the actual sucrose content of sugar beet digestion liquids a new modification of the direct isotopic dilution method was worked out, which is easier to perform than the existing modifications. With the aid of sucrose standard solutions and samples of sucrose, glucose, fructose and raffinose in hydrous lead acetate solutions the degree of accuracy of the method was determined, which is better than +- 2%. During the 1973/74 campaign the direct isotopic dilution method was used for determining the actual sucrose content of sugar beet digestion liquids and the measuring results were compared with results of polarimetric determinations. With digestion liquids taken from healthy beet material it was found that the radioactive and polarimetric measuring results agreed well. With digestion fluids from purifying sugar beets having a lower sucrose level, however, there resulted differences between the measuring results of the two methods mentioned which were considerably greater than those dependent on error limits.

    2016-09-01

    We profiled triterpene saponins from the roots of sugar beet Beta vulgaris L. cultivars Huzar and Boryna using reversed-phase liquid chromatography combined with negative-ion electrospray ionization quadrupole mass spectrometry. We tentatively identified 26 triterpene saponins, including 17 that had not been detected previously in this plant species and 7 saponins that were tentatively identified as new compounds. All observed compounds were glycosides of five different aglycones, of which gypsogenin and norhederagenin are reported for the first time in sugar beet. Thirteen of the saponins detected in sugar beet roots were substituted with dioxolane-type (4 saponins) or acetal-type (9 saponins) dicarboxylic acids. Among the 26 detected saponins, we identified 2 groups of isomers distinguished using high-resolution mass measurements that were detected only in the Huzar cultivar of sugar beet. PMID:27423042

    2004-12-01

    Full Text Available Abstract Background Modification of leaf traits in sugar beet requires a strong leaf specific promoter. With such a promoter, expression in taproots can be avoided which may otherwise take away available energy resources for sugar accumulation. Results Suppression Subtractive Hybridization (SSH was utilized to generate an enriched and equalized cDNA library for leaf expressed genes from sugar beet. Fourteen cDNA fragments corresponding to thirteen different genes were isolated. Northern blot analysis indicates the desired tissue specificity of these genes. The promoters for two chlorophyll a/b binding protein genes (Bvcab11 and Bvcab12 were isolated, linked to reporter genes, and transformed into sugar beet using promoter reporter gene fusions. Transient and transgenic analysis indicate that both promoters direct leaf specific gene expression. A bioinformatic analysis revealed that the Bvcab11 promoter is void of G-box like regulatory elements with a palindromic ACGT core sequence. The data indicate that the presence of a G-box element is not a prerequisite for leaf specific and light induced gene expression in sugar beet. Conclusions This work shows that SSH can be successfully employed for the identification and subsequent isolation of tissue specific sugar beet promoters. These promoters are shown to drive strong leaf specific gene expression in transgenic sugar beet. The application of these promoters for expressing resistance improving genes against foliar diseases is discussed.

  11. Applying Adaptive Agricultural Management & Industrial Ecology Principles to Produce Lower- Carbon Ethanol from California Energy Beets

    Science.gov (United States)

    Alexiades, Anthy Maria

    The life cycle assessment of a proposed beet-to-ethanol pathway demonstrates how agricultural management and industrial ecology principles can be applied to reduce greenhouse gas emissions, minimize agrochemical inputs and waste, provide ecosystem services and yield a lower-carbon fuel from a highly land-use efficient, first-generation feedstock cultivated in California. Beets grown in California have unique potential as a biofuel feedstock. A mature agricultural product with well-developed supply chains, beet-sugar production in California has contracted over recent decades, leaving idle production capacity and forcing growers to seek other crops for use in rotation or find a new market for beets. California's Low Carbon Fuel Standard (LCFS) faces risk of steeply-rising compliance costs, as greenhouse gas reduction targets in the transportation sector were established assuming commercial volumes of lower-carbon fuels from second-generation feedstocks -- such as residues, waste, algae and cellulosic crops -- would be available by 2020. The expected shortfall of cellulosic ethanol has created an immediate need to develop lower-carbon fuels from readily available feedstocks using conventional conversion technologies. The life cycle carbon intensity of this ethanol pathway is less than 28 gCO2e/MJEthanol: a 72% reduction compared to gasoline and 19% lower than the most efficient corn ethanol pathway (34 gCO2e/MJ not including indirect land use change) approved under LCFS. The system relies primarily on waste-to-energy resources; nearly 18 gCO2e/MJ are avoided by using renewable heat and power generated from anaerobic digestion of fermentation stillage and gasification of orchard residues to meet 88% of the facility's steam demand. Co-products displace 2 gCO2e/MJ. Beet cultivation is the largest source of emissions, contributing 15 gCO 2e/MJ. The goal of the study is to explore opportunities to minimize carbon intensity of beet-ethanol and investigate the potential

    Like other halophytic chenopods, sugar beet (Beta vulgaris L.) can accumulate high betaine levels in shoots and roots. N,N,N-trimethylglycine impedes sucrose crystallization and so lowers beet quality. The objective of this research was to examine the genetic variability and physiological significance of betaine accumulation in sugar beet and its relatives. Three cultivated genotypes of B. vulgaris and two genotypes of the wild progenitor B. maritima L. were grown with and without gradual salinization (final NaCl concentration = 150 millimolar). At 6 weeks old, all five genotypes had moderately high betaine levels in shoots and roots when unsalinized (averages for all genotypes: shoots = 108 micromoles per gram dry weight; roots = 99 micromoles per gram dry weight). Salinization raised betaine levels of shoots and roots 2- to 3-fold, but did not greatly depress shoot or root growth. The genotype WB-167-an annual B. maritima type-always had approximately 40% lower betaine levels in roots than the other four genotypes, although the betaine levels in the shoots were not atypically low.THE SITE AND PATHWAY OF BETAINE SYNTHESIS WERE INVESTIGATED IN YOUNG, SALINIZED SUGAR BEET PLANTS BY: (a) supplying 1 micromole [(14)C]ethanolamine to young leaf blades or to the taproot sink of intact plants; (b) supplying tracer [(14)C]formate to discs of leaf, hypocotyl, and taproot tissues in darkness. Conversion of both (14)C precursors to betaine was active only in leaf tissue. Very little (14)C appeared in the phospholipid phosphatidylcholine before betaine was heavily labeled; this was in marked contrast to the labeling patterns in salinized barley. Phosphorylcholine was a prominent early (14)C metabolite of both [(14)C]ethanolamine and [(14)C]formate in all tissues of sugar beet. Betaine translocation was examined in young plants of sugar beet and WB-167 by applying tracer [methyl-(14)C]betaine to a young expanded leaf and determining the distribution of (14)C after 3 days.

    Depending on environmental factors fungal diseases of crops are often distributed heterogeneously in fields. Precision agriculture in plant protection implies a targeted fungicide application adjusted these field heterogeneities. Therefore an understanding of the spatial and temporal occurrence of pathogens is elementary. As shown in previous studies, remote sensing techniques can be used to detect and observe spectral anomalies in the field. In 2008, a sugar beet field site was observed at different growth stages of the crop using different remote sensing techniques. The experimental field site consisted of two treatments. One plot was sprayed with a fungicide to avoid fungal infections. In order to obtain sugar beet plants infected with foliar diseases the other plot was not sprayed. Remote sensing data were acquired from the high-resolution airborne hyperspectral imaging ROSIS in July 2008 at sugar beet growth stage 39 and from the HyMap sensor systems in August 2008 at sugar beet growth stage 45, respectively. Additionally hyperspectral signatures of diseased and non-diseased sugar beet plants were measured with a non-imaging hand held spectroradiometer at growth stage 49 in September. Ground truth data, in particular disease severity were collected at 50 sampling points in the field. Changes of reflection rates were related to disease severity increasing with time. Erysiphe betae causing powdery mildew was the most frequent leaf pathogen. A classification of healthy and diseased sugar beets in the field was possible by using hyperspectral vegetation indices calculated from canopy reflectance.

    BACKGROUND: Starch is the predominant storage compound in underground plant tissues like roots and tubers. An exception is sugar beet tap-root (Beta vulgaris ssp altissima) which exclusively stores sucrose. The underlying mechanism behind this divergent storage accumulation in sugar beet is currently not fully known. From the general presence of starch in roots and tubers it could be speculated that the lack in sugar beet tap-roots would originate from deficiency in pathways leading to starch...

  19. Betaine and beet molasses enhance L-lactic acid production by Bacillus coagulans.

    Directory of Open Access Journals (Sweden)

    Ke Xu

    Full Text Available Lactic acid is an important chemical with various industrial applications, and it can be efficiently produced by fermentation, in which Bacillus coagulans strains present excellent performance. Betaine can promote lactic acid fermentation as an effective osmoprotectant. Here, positive effect of betaine on fermentation by B. coagulans is revealed. Betaine could enhance lactic acid production by protecting l-LDH activity and cell growth from osmotic inhibition, especially under high glucose concentrations and with poor organic nitrogen nutrients. The fermentation with 0.05 g/L betaine could produce 17.9% more lactic acid compared to the fermentation without betaine. Beet molasses, which is rich in sucrose and betaine, was utilized in a co-feeding fermentation and raised the productivity by 22%. The efficient lactic acid fermentation by B. coagulans is thus developed by using betaine and beet molasses.

    Full Text Available In the years 1975-1980, on the Experimental Farm Chylice fields of the Warsaw Agricultural University, herbicide activity was evaluated on commonly appearing weed species in sugar beet cultivation. The most frequent weeds were: Chenopodium album, Echinochloa crus-galli, Polygonum convolvulus and Polygonum lapatifolium. Preemergence use of chloridazon and furthermore postemergence use of phenmedipham were most effective in control. Metolachlor or bentiocarb mixed with metamitron and chloridazon were effective too. It was found that 70% control of Chenopodium album increased crops of sugar beets by about 25% on the basis of two years experiments (1979-1980, differing in quantity and periods of rainfall, a visible dependence of herbicide effectiveness on climatic conditions was demonstrated.

    This paper presents a novel approach for identification of terahertz (THz) spectral of genetically modified organisms (GMOs) based on Hyper Sausage Neuron (HSN), and THz transmittance spectra of some typical transgenic sugar-beet samples are investigated to demonstrate its feasibility. Principal component analysis (PCA) is applied to extract features of the spectrum data, and instead of the original spectrum data, the feature signals are fed into the HSN pattern recognition, a new multiple weights neural network (MWNN). The experimental result shows that the HSN model not only can correctly classify different types of transgenic sugar-beets, but also can reject identity non similar samples in the same type. The proposed approach provides a new effective method for detection and identification of GMOs by using THz spectroscopy.

    A suitable alternative to replace fossil fuels is the production of bioethanol from agroindustrial waste. Grape pomace is the most abundant residue in San Juan and sugar beet pomace could be important in the region. Solid-State Fermentation (SSF) is a technology that allows transforming agroindustrial waste into many valuable bioproducts, like ethanol. This work reports a laboratory scale SSF to obtain alcohol from grape and sugar beet pomace by means of Saccharomyces cerevisiae yeasts. The initial conditions of the culture medium were: sugars 16.5% (p/p); pH 4.5; humidity 68% (p/p). Cultures were inoculated with 10{sup 8} cells/g of pomace, and incubated in anaerobic environment, at 28 C, during 96 h. SSF showed ethanol maximum concentrations at 48 h and ethanol yield on sugars consumed was more than 82%. Yield attained creates expectation about the use of SSF to obtain fuel alcohol. (author)

    Full Text Available In the period 2001-2004, experiments were conducted in the region of Bačka (northern Serbia to assess the efficiency of insecticide treatment of sugar beet seeds in controlling soil pests (larvae of Elateridae family and reducing the damage caused by beet weevil (Bothynoderes punctiventris G e r m and flea beetle (Chaetocnema tibialis I l l i g. Several insecticides mostly systemic ones (carbofuran, thiamethoxam, fipronil, imidacloprid and clothianidin, and their combinations with pyrethroids in different doses were tested in field conditions. Stand density, percentages of plants damaged by B. punctiventris and C. tibialis, injury level and weight of juvenile plants served as parameters for evaluation of insecticide efficiency. Most of the insecticides applied to seeds provided a significantly better stand density compared with the untreated control. Because of their systemic action, imidacloprid, thiamethoxam and their mixtures with pyrethroids provided very good protection of juvenile plants from C. tibialis and in some cases from B. punctiventris.

    Full Text Available Purpose: The paper presents two sowing machines for interval sowing, differing in the mode of operation. The pneumatic vacuum sowing machine OLT and the pneumatic pressure sowing machine Aeromat - Becker for sowing sugar beet are compared. We were interested in adequacy of sowing at different working speeds. The purpose of the paper is to find out the optimum working speed for the individual sowing machine.Design/methodology/approach: The measurements were performed with two sowing machines which are most widely used in Slovenia; the sowing machines were tested in completely identical conditions at different speeds of sowing.Findings: The parameters such as working efficiency, depth of sowing, inter - row distance and distance between seeds in the sowing row were measured and calculated.Research limitations/implications: Cultivation of sugar beet depends primarily on expert and technically correct sowing. Distance between seeds in the sowing row must enable the plants to have optimum conditions for their growth and development. For successful sowing it is necessary to know adequacy of the soil for sowing, technical properties of the sowing machine and biotechnical characteristics of the seed.Practical implications: Sowing machines and expertly performed sowing are of great importance for cultivation of sugar beet. The principal aim of the paper is to establish whether the higher working speed influences the quality of sowing. The tests were aimed at defining the most suitable sowing speed for both sowing machines on the basis of measured data. Cultivation of sugar beet requires much money invested and work performed per unit of area. It is very important for the producers to be well familiarized with all agro - technical measures.Originality/value: Taking into account all measured parameters the optimum sowing speed of the pneumatic vacuum machine OLT is 8 km/h and the optimum sowing speed of the pneumatic pressure sowing machine Aeromat

    Full Text Available Sugar beet root rot appears regularly each year, but its intensity depends on agro ecological conditions. The predominant causers of root rot in Vojvodina are fungi from Fusarium genus and species Macrophomina phaseolina. Over the last couple of years, more intense occurrence of Rhizoctonia root rot has been observed. Rhizoctonia solani, the causal agent of root rot is present in sugar beet fields. During 2000-2005, on the territory of Vojvodina, the frequency of Rhizoctonia solani in phytopathological isolations from rotted sugar beet roots was between 0,0-18,2%. The intensity of the disease depends on localities, agro ecological conditions and genotypes. Symptoms of Rhizoctonia root rot were registered at some localities in all regions of Vojvodina: Srem, Banat and Bačka. The disease appearance is above all local. It occurs in small patches, on heavy, non-structured soil and on depressed wet parts of plots. Individual diseased plants can be found during July. Brown rot appears on sugar beet roots, with dried tissue on surface, which is present on the tail as well as on the middle part and the head of root. Tissues with described symptoms are deeper regarding the healthy part of root. On vertical root section, the necrotic changes are clearly visible comparing to tissue section without symptoms. The heavily infected tissue forms fissures on roots in most cases. Besides the above-mentioned symptoms on roots, the plant wilting and leaf handle necrosis as well as leaf dying are also observed. When rot spreads to the whole root head, plants quickly die.

    Full Text Available Total, soluble and insoluble oxalates were extracted and analyzed by high performance liquid chromatography (HPLC following the preparation of kimchi using silver beet (Beta vulgaris var. cicla stems and leaves. As silver beet contains high oxalate concentrations and consumption of high levels can cause the development of kidney stones in some people, the reduction of oxalate during preparation and fermentation of kimchi was investigated. The silver beet stems and leaves were soaked in a 10% brine solution for 11 h and then washed in cold tap water. The total, soluble and insoluble oxalate contents of the silver beet leaves were reduced by soaking in brine, from 4275.81 ± 165.48 mg/100 g to 3709.49 ± 216.51 mg/100 g fresh weight (FW. Fermenting the kimchi for 5 days at 19.3 ± 0.8 °C in 5 L ceramic jars with a water airtight seal resulted in a mean 38.50% reduction in total oxalate content and a mean 22.86% reduction in soluble oxalates. The total calcium content was essentially the same before and after the fermentation of the kimchi (mean 296.1 mg/100 g FW. The study showed that fermentation of kimchi significantly (p < 0.05 reduced the total oxalate concentration in the initial mix from 609.32 ± 15.69 to 374.71 ± 7.94 mg/100 g FW in the final mix which led to a 72.3% reduction in the amount of calcium bound to insoluble oxalate.

    International Nuclear Information System (INIS)

    Investigations were carried out with the aim of determining ploidy status, at short and long intervals, using suspension and protoplast cultures and seedlings of Beta vulgaris L. var. altissima cv. Hymona (sugar-beet). Two rapid-growing strains of sugar-beet were used, strain B.14.1, with a ploidy level of 8c to 64c (with maxima between 8c and 16c) and strain B.1.9, varying in DNA content from 16c to 128c (with a maximum frequency between 32c and 64c). Long-term studies of about two years resulted in constant ploidy spectrum, whereas short-term analyses under turbidostatic conditions showed more or less regular oscillations in the frequency distribution, with an amplitude of 20-40% of the medium ploidy level and with an oscillation period of 1-2 days. The isolation of protoplasts from the two strains and the measurement of their ploidy levels before and after isolation, and at longer periods thereafter, showed a shift in ploidy level immediately after isolation. Studies on the ploidy levels in seeds and seedlings of sugar-beet could yield evidence that heterogeneity in the ploidy patterns of cell cultures is not a feature of cultivated cells or tissue alone, but also occurs naturally during plant development.

    Full Text Available Information about genetic diversity and combining abilities of sugar beet parental components are of a great importance for hybrid creation. The aim of this research was to evaluate genetic diversity among sugar beet pollinators from different breeding programs and their combining abilities for main root traits of sugar beet, root weight, sugar content and sugar yield. As plant material were used eight pollinators originating from three different USDA-ARS breeding programs and four from Institute of field and vegetable crops Novi Sad. The analysis of variance and Duncan’s multiple range test revealed significant differences (p = 0.05 among pollinators for all investigated traits. Pollinator CR10 differs from all others in terms of quantitative traits and in terms of combining ability. Despite small root weight CR10 had significantly positive GCA for that trait and showed that genotypes with small root should not be automatically discarded. Pollinators from Institute of field and vegetable crops used in this research had negative GCA for root weight and should be used only as hosts for introduction of new germplasm in future breeding program.

    Full Text Available Sugar beet is the most important crop for sugar production in Europe. Wide genetic variability is essential in sugar beet breeding programs. The aim of this study is to evaluate variability for the main root traits and differences between monogerm and multigerm sugar beet genotypes from the breeding collection at the Institute of Field and Vegetable Crops. The following traits were analyzed: root weight (g, dry matter content (%, root head weight (g, root/head ratio (%, number of cambial rings, root length (cm and root diameter (cm. Mean values for two years per genotype were standardized and used for analysis. Principal Component Analysis (PCA and Cluster Analysis (CA were used to examine the level of diversity for 20 genotypes and to rank the contributions of the variables. According to CA genotypes could be placed into five main groups, where a large number of multigerm genotypes were put in one group. On average multigerm genotypes were characterized by higher mean values for root weight, length, diameter and lower root head ratio. Multigerm genotypes had higher coefficients of variation for nearly all measured root traits. [Projekat Ministarstva nauke Republike Srbije, br. TR31015

Results showed that: 1. Low dosage (3 Krad) of gamma rays gave a stimulated effect on germination percentage for monogerm variety and depressed that of multigerm variety. 2. Irradiation sugar beet seeds with 9 Krad had given a stimulated effect on root yield for two varieties and yield of leaves of the multigerm variety in both seasons. 3. Doses from 6 to 12 Krad exerted a favourable and pronounced effect on root weight for the first rate and leaves for the later rate/plant. 4. Irradiation treatments had no effect on percent brise of the two varieties and percent purity during the two growing seasons except for the purity of the multigerm variety. 5. Low doses up to 9 Krad gave a significant increase on sucrose % and purity of the monogerm in the two growing seasons. 6.

    High nitrate intake has been shown to result in an increased risk of endogenous formation of N-nitroso compounds. Certain vegetables and vegetable juices contain high concentrations of nitrate. Biological denitrification using strains of Paracoccus denitrificans (P.d.) has been proposed as effective means to reduce nitrate contents in such vegetable juices. During this bacterial denitrification process, substantial nitrite concentrations are transiently formed. This study investigated whether N-nitrosation reactions might occur. The easily nitrosatable amine morpholine was added to red beet juice at high concentration (100 ppm) during denitrification 10 different batches of red beet juice served as raw material. Each batch was submitted to denitrification in the presence and absence of ascorbic acid. In the absence of ascorbic acid, formation of N-nitrosomorpholine (NMOR) was observed in the low ppb range (0.5-8 ppb). Addition of ascorbic acid (500 mg/litre) inhibited the formation of NMOR, except for those instances where the pH was less than 6 and/or nitrate turnover was low (high rates of nitrate turnover (> 200 mg NO3-/litre/hr), nitrosamine formation can reliably be prevented by ascorbic acid. The results show that bacterial denitrification of red beet juice high in nitrate can be accomplished without the risk of nitrosamine formation. PMID:9146735

    Anaerobic digestion (AD) is a promising option for the environmentally friendly recycling of agricultural by-products. However, overloading of the digester with sugar, starch or protein might cause inhibition of the anaerobic processes. The aim of the present project was to investigate the AD of sugar beet, starch potato by-products and effect of pre-treatment by steam on methane yield of potatoes pulp. The investigated by-products have been: sugar beet pulp silage (SBP), sugar beet tail silage (SBT), potato pulp (PP), potato peel pulp (PPP) and potato fruit water (PFW). All by-products were digested in 1 l eudiometer-batch digesters at 37.5 C during 28-38 days. The specific methane yields of SBP and SBT were 430 and 481 l{sub N} kg{sup -1} volatile solids (VS), respectively. The specific methane yields of PP, PPP and PFW were 332, 377 and 323 l{sub N} (kg VS){sup -1}. A steam pre-treatment significantly increased the specific methane yield of PP up to 373 l{sub N} (kg VS){sup -1}. (author)

    Storage rots represent an economically important factor impairing the storability of sugar beet by increasing sucrose losses and invert sugar content. Understanding the development of disease management strategies, knowledge about major storage pathogens, and factors influencing their occurrence is crucial. In comprehensive storage trials conducted under controlled conditions, the effects of environment and genotype on rot development and associated quality changes were investigated. Prevalent species involved in rot development were identified by a newly developed microarray. The strongest effect on rot development was assigned to environment factors followed by genotypic effects. Despite large variation in rot severity (sample range 0 to 84%), the spectrum of microorganisms colonizing sugar beet remained fairly constant across all treatments with dominant species belonging to the fungal genera Botrytis, Fusarium, and Penicillium. The intensity of microbial tissue necrotization was strongly correlated with sucrose losses (R² = 0.79 to 0.91) and invert sugar accumulation (R² = 0.91 to 0.95). A storage rot resistance bioassay was developed that could successfully reproduce the genotype ranking observed in storage trials. Quantification of fungal biomass indicates that genetic resistance is based on a quantitative mechanism. Further work is required to understand the large environmental influence on rot development in sugar beet. PMID:26474333

    2011-08-01

    Full Text Available Abstract Background In soils with a low phosphorus (P supply, sugar beet is known to intake more P than other species such as maize, wheat, or groundnut. We hypothesized that organic compounds exuded by sugar beet roots solubilize soil P and that this exudation is stimulated by P starvation. Results Root exudates were collected from plants grown in hydroponics under low- and high-P availability. Exudate components were separated by HPLC, ionized by electrospray, and detected by mass spectrometry in the range of mass-to-charge ratio (m/z from 100 to 1000. Eight mass spectrometric signals were enhanced at least 5-fold by low P availability at all harvest times. Among these signals, negative ions with an m/z of 137 and 147 were shown to originate from salicylic acid and citramalic acid. The ability of both compounds to mobilize soil P was demonstrated by incubation of pure substances with Oxisol soil fertilized with calcium phosphate. Conclusions Root exudates of sugar beet contain salicylic acid and citramalic acid, the latter of which has rarely been detected in plants so far. Both metabolites solubilize soil P and their exudation by roots is stimulated by P deficiency. These results provide the first assignment of a biological function to citramalic acid of plant origin.

    Full Text Available In the present investigation, aimed at obtaining beet haploids from anthers, the effect of mineral media, potato and sugar beet extract and p-fluorophenylalanine (PFP in combination with growth substances was tested. Nutrient-starved plants as anther-donors, anther-starvation, cold treatment and photoperiod were also analysed. On all mineral media the anthers produced callus and roots; however, the percentage depended on the combination of growth substances used. The best medium for differentiation was that of Linsmaier and Skoog with 25 µM zeatin or 6-(3-methyl-2-butenylaminopurine with 5 µM naphthalene-l-acetic acid (25.5%. The addition of PFP caused an increase in the percentage of anther differentiation (41.6%. Besides callus and roots on one of the anthers (in ca. 140000 tested, vegetative buds were formed from which numerous plants were obtained (2n. Plant and anther nutrient starvation did not improve the anther response to differentiation, nor did it induce haploid development, similarly as cold treatment of inflorescences or isolated anthers. The anthers of wild species showed lower ability to differentiate than those of sugar or fodder beets. Cytological analyses showed formation of multicellular structures until ca. the 12-th day of anther culture; afterwards, they degenerated.

    Cercospora leaf spot (CLS) caused by Cercospora beticola is the most destructive leaf disease of sugar beet and may cause high losses in yield and quality. Breeding and cultivation of disease-resistant varieties is an important strategy to control this economically relevant plant disease. Reliable and robust resistance parameters are required to promote breeding progress. CLS lesions on five different sugar beet genotypes incubated under controlled conditions were analyzed for phenotypic differences related to field resistance to C. beticola. Lesions of CLS were rated by classical quantitative and qualitative methods in combination with noninvasive hyperspectral imaging. Calculating the ratio of lesion center to lesion margin, four CLS phenotypes were identified that vary in size and spatial composition. Lesions could be differentiated into subareas based on their spectral characteristics in the range of 400 to 900 nm. Sugar beet genotypes with lower disease severity typically had lesions with smaller centers compared with highly susceptible genotypes. Accordingly, the number of conidia per diseased leaf area on resistant plants was lower. The assessment of lesion phenotypes by hyperspectral imaging with regard to sporulation may be an appropriate method to identify subtle differences in disease resistance. The spectral and spatial analysis of the lesions has the potential to improve the screening process in breeding for CLS resistance. PMID:26506458

  18. Ecological Study of Two Aphid Vectors of the Sugar-Beet Virus

    International Nuclear Information System (INIS)

    The dispersal of Myzus persicae Sulz and Aphis fabae Scop, labelled with 32P was studied from 1963 to 1965 in sugar-beet plots. The aphids were reared on beets infected with a virus causing severe yellowing and sprinkled with a solution containing 1 mCi of sodium orthophosphate (32P). Aphids which remained for 24 hours on these plants were significantly labelled, as were also their first-generation descendants. The activity of the insects was recorded by a gas-flow detector with a low background. The radioactive beets infected with the virus and laden with aphids were placed in the centre of the plots. After successively increasing dispersal times, the largest possible number of aphids was captured in each test, either manually or in traps. The co-ordinates and the precise identification of each labelled aphid were entered on charts, some of which are discussed by the authors. The experiments demonstrated the mobility of the aplerae, which were found at average distances of 6.5 and 7 metres for Myzus persicae and Aphis fabae, respectively. However, some apterae of both species were found at distances of over 15 metres after the same period. The role of the winged species as virus carries over short distances should not be underestimated. The active character of both apterae and winged species is emphasized. (author)

The efficiency of pectin precipitation was monitored by measuring the zeta potential of pectin preparations. Optimal amounts of precipitant CaSO4, without the use of a cationic polyelectrolyte, were as follows: 490-678 mg CaSO4/g pectin. After the use of a cationic polyelectrolyte, the optimal amounts of CaSO4 were smaller (353-512 mg/g pectin. These quantities are significantly lower than the average amount of CaO used in the conventional clarification process of sugar beet juice (about 9 g/g pectin of sugar beet juice.

    In this research the effect of industrial sugar beet wastewater has been assessed on the soil water content properties in summer 2005. The evaluated parameters were the soil water content points such as Saturation Percent (SP), Field Capacity (FC), Permanent Wilting Point (PWP), gravitational water and Total Available Water (TAW). The pilot design was fully randomized with three replications and three treatments. The three treatments were: 1-normal water, 2-industrial sugar beet wastewater (50%) and normal water (50%) and 3-sugar beet wastewater (100%). The experiments have been carried out in the field, in 21 columns with the diameter 110 mm and the height of 400 mm. The soil was irrigated using surface irrigation method for 12 events with a constant volume and period. Based on the result, the SP, FC and PWP initial value were 46.5, 35 and 15%, respectively for all the treatments. At the end of the period, the values changed to 47, 36.6 and 17.5% for T2. They are also increased significantly to 48.5, 37 and 18.7% for T3 at the end of the period. The increasing of soil Organic Matter (OM) during the period is expected to be the main factor for this change. The result shows that although the FC and PWP parameters are increased during the period but TAW decreased significantly from the 20 to 18.5%. The other effects of wastewater on soil and leached water quality should be evaluated too. PMID:19086512

    Full Text Available Remorins, a family of plant-specific proteins containing a variable N-terminal region and conserved C-terminal domain, play a role in various biotic and abiotic stresses, including host-microbe interactions. However, their functions remain to be completely elucidated, especially for the Arabidopsis thaliana remorin group 4 (AtREM4. To elucidate the role of remorins in Arabidopsis, we first showed that AtREM4s have typical molecular characteristics of the remorins, such as induction by various types of biotic and abiotic stresses, localization in plasma membrane and homo- and hetero-oligomeric interaction. Next, we showed that their loss-of-function mutants displayed reduced susceptibility to geminiviruses, Beet Curly Top Virus and Beet Severe Curly Top Virus, while overexpressors enhanced susceptibility. Moreover, we found that they interacted with SnRK1, which phosphorylated AtREM4.1, and were degraded by the 26S proteasome pathway. These results suggest that AtREM4s may be involved in the SnRK1-mediated signaling pathway and play a role as positive regulators of the cell cycle during geminivirus infection.

  3. Sugar-beet irrigation scheduling and the possibilties of using a neutron probe to measure soil moisture in northeastern Yugoslavia

    International Nuclear Information System (INIS)

    The paper reviews the results of a study of irrigation scheduling for sugar-beet in northeastern Yugoslavia - Vojvodina Province - under conditions of a semi-humid climate. The region has suitable soil and climatic conditions for sugar-beet. The limiting factor for high and stable yields is an insufficient and unfavourably distributed rainfall which is compensated for by irrigation. The irrigation in the region under discussion is strictly supplementary. The crucial problem is the determination of irrigation scheduling. It has been found that four scheduling methods may be used. The irrigation method based on soil moisture applies 600 m3/ha of water at 65% filled water capacity. This method, made simpler and more efficient by using a neutron probe, resulted in the highest yields in the experiment. Sugar-beets increase their water requirements in the course of growth and development. One irrigation is necessary in the first stage. Two irrigations (1200 m3/ha) suffice for the second stage (1 July - 20 August). At the stage of technological maturity, sugar-beet requirements for water are the lowest - one irrigation is enough. The level of water provision for sugar-beet may also be controlled by analysing the concentration of cell sap in the leaf. The marginal values are 7% till the end of June and 8% in July and August. The bioclimatic method of calculating sugar-beet requirements for water has certain advantages. It was found that sugar-beet uses 1.8 m3/ha of water each 1 deg. C mean daily air temperature. As the crop varies so do its water requirements and the phytobioclimatic coefficient. (author)

  4. Repair of dipyrimidine dimers formed during the UVC irradiation of sugar beet

    International Nuclear Information System (INIS)

    Most of the mutations induced in living organisms by both mid- and short wave UV irradiation are located at dipyrimidine sites. The two major classes of photoproducts induced by UVC are cyclobutane pyrimidine dimers (CPD) and the pyrimidine pyramidones (6,4 photoproducts), constituting the two major mutagenic lesions. This paper reports investigations into the repair efficiency of the two classes of photoproducts induced by UVC and the relative importance of photoreactivation (light repair) and excision repair (dark repair) in sugar beet plants. The overall objective of the study is to determine whether differences in tolerance to UV-induced stress occur in sugar beet varieties. The results from yeast and mammalian systems indicate that 6-4 photoproducts are repaired much more rapidly than cyclobutane dimers. The present work investigates CPD and 6-4 photoproducts independently, as well as total lesions, in sugar beet hypocotyls and cotyledons irradiated with UVC at 20-200 J.m-2. The amount of damage to DNA and the speed of both light and dark repair has been determined in experiments over periods from 30 min to 3 hours. The technique applied involves dot blot immunoassay using a polyclonal antiserum raised against UVC-irradiated DNA. Detection of the individual lesions was based on their differential sensitivities to hot alkali and photoreactivating enzyme. It has been shown that hypocotyls and cotyledons were affected by UV irradiation at all the doses used. The dot blot immunoassay has allowed determination of total lesions and each type of lesion independently in sugar beet tissues. At all UVC doses the damage was repaired in the light (photoreactivation) in 2-3 hours. In hypocotyls some 'dark repair' occurred at the lower doses (20 and 50 Jm-2) but not at the higher doses (100 and 200 Jm-2). Although it can be concluded that sugar beet plants are able to repair damage caused by UVC irradiation, work is continuing to determine which of the two mechanisms is

    Full Text Available Sugar beet is one of the most important agricultural crops in the Republic of Moldova. The North and Central regions have good enough pedoclimatic conditions. The genetic potential of sorts and hybrids can be created through the application of modern technologies in order to grow at least 32-35 tons/ha of sugar beet roots. In the Republic of Moldova, sugar beet vegetates between 160 and 180 days in the first year and needs approximately an amount of 2400-2900°C, average of 15.3-15.4°C. Each phenological phase needs different temperatures: at least 4C° is necessary for planting and springing an amount of 650°C is necessary for foliar apparatus; an amount of 1150- 1800°C is necessary to grow the volume of roots and for sugar depositing the average of 2400 to 2600°C is necessary. The mentioned temperatures ensure a normal development of sugar beet plants. If these temperatures fluctuate, the pathogens and pests are stimulated to develop. The most frequent diseases of sugar beet are: Pythium de baryanum Hesse., Aphanomyces cochlioides Dresch. Peronospora schachtii Fuck., Phoma betae Fr. Cercospora beticola Sacc. Erysiphe communis Grev. f. betae Jacz., virosis - Beta virus 2, 3 si 4 etc. The main pests belong to the following categories: Homoptera: Aphis fabae Scop. (fam.

    Full Text Available Abstract Background With a cultivation area of 1.75 Mio ha and sugar yield of 16.7 Mio tons in 2006, sugar beet is a crop of great economic importance in Europe. The productivity of sugar beet is determined significantly by seed vigour and field emergence potential; however, little is known about the molecular mechanisms underlying these traits. Both traits exhibit large variations within sugar beet germplasm that have been difficult to ascribe to either environmental or genetic causes. Among potential targets for trait improvement, an enhancement of stress tolerance is considered because of the high negative influence of environmental stresses on trait parameters. Extending our knowledge of genetic and molecular determinants of sugar beet germination, stress response and adaptation mechanisms would facilitate the detection of new targets for breeding crop with an enhanced field emergence potential. Results To gain insight into the sugar beet germination we initiated an analysis of gene expression in a well emerging sugar beet hybrid showing high germination potential under various environmental conditions. A total of 2,784 ESTs representing 2,251 'unigenes' was generated from dry mature and germinating seeds. Analysis of the temporal expression of these genes during germination under non-stress conditions uncovered drastic transcriptional changes accompanying a shift from quiescent to metabolically active stages of the plant life cycle. Assay of germination under stressful conditions revealed 157 genes showing significantly different expression patterns in response to stress. As deduced from transcriptome data, stress adaptation mechanisms included an alteration in reserve mobilization pathways, an accumulation of the osmoprotectant glycine betaine, late embryogenesis abundant proteins and detoxification enzymes. The observed transcriptional changes are supposed to be regulated by ABA-dependent signal transduction pathway. Conclusion This study

    The objective of this study was to evaluate the effect of human urine and wood ash fertilization on the yield and quality of red beet by measuring the microbial, nutrient, and antioxidant (betanin) content of the roots. Red beets were fertilized with 133 kg of N/ha as mineral fertilizer, urine and ash, and only urine with no fertilizer as a control. The mineral-fertilized plants and urine- and ash-fertilized plants also received 89 kg of P/ha. Urine and ash and only urine fertilizer produced 1720 and 656 kg/ha more root biomass, respectively, versus what was obtained from the mineral fertilizer. Few fecal coliforms and coliphage were detected in mineral-fertilized and urine- and ash-fertilized red beet roots. The protein and betanin contents in red beet roots were similar in all treatments. In conclusion, this study revealed that urine with or without ash can increase the yield of red beet and furthermore the microbial quality and chemical quality were similar to the situation in mineral-fertilized products.

    Faster sugar consumption rate and low-cost nitrogen source are required for the chemical biosynthesis using molasses. Five pretreatment methods were applied to beet molasses prior to fermentation through engineered Escherichia coli, respectively, and corn steep liquid was used as an organic nitrogen source to replace expensive yeast extract. Furthermore, the effects of different feeding strategy in fed-batch fermentation on L-lysine production were investigated. The experimental results showed that combined tricalcium phosphate, sulfuric acid, and activated carbon pretreatment method (TPSA) pretreatment could improve the sugar consumption rate most greatly, and the initial total sugar concentration of 35 g/L from TPSA-pretreated beet molasses gave the best results with respect to L-lysine production, dry cell weight concentration, and L-lysine yield in batch fermentation. Moreover, a mixture of low-cost corn steep liquid and yeast extract containing equal amount of nitrogen could be used as the organic nitrogen source for effective L-lysine fermentation, and constant speed feeding strategy of TPSA-pretreated beet molasses promoted L-lysine production by engineered E. coli. The TPSA-pretreated beet molasses had a sugar consumption rate of 1.75 g/(L h), and a L-lysine yield of 27.81% was achieved, compared with the theoretical yield of 62% by glucose. It was clarified that the pretreatment significantly enhanced the conversion of sugars in beet molasses to L-lysine. PMID:25899726

    Full Text Available Aim: The objective of this study was to evaluate the effects of sugar beet tubers as a replacer to green fodder on production performance and economics of lactating Surti buffaloes. Materials and Methods: This trial was conducted at the Livestock Research Station, Navsari Agricultural University, Navsari. Twenty lactating Surti buffaloes in a changeover experimental design were selected to assess the effects of replacing green fodder with sugar beet (Beta vulgaris L. tubers on production performance, economics of feeding sugar beet and blood biochemical profile. Half (50% of the hybrid Napier was replaced with sliced sugar beet tubers in the ration of experimental animals. Results: Partial replacement of hybrid Napier with that of sugar beet tubers numerically improved dry matter intake, milk yield, 4% fat corrected milk and milk composition parameters such as fat, solid non-fat, protein and lactose, but not significantly. The blood parameters were in normal range and non-significant except that of glucose and triglycerides, which were increased in the sugar beet group. Replacing sugar beet tubers also proved to be cost-effective with improved net profit around Rs. 6.63/day. Conclusion: It can be concluded that 50% hybrid Napier fodder can be replaced with sugar beet tubers without any adverse effect on animal production performance, milk composition blood biochemical profile and economics of feeding.

    Sugar beet molasses is a raw material with high potential to be a functional ingredient in baked goods. This paper investigated the nutritional and functional properties of gluten-free cookies enriched with sugar beet molasses. At all enrichment levels and forms tested (liquid and dry), the addition of beet molasses improved the micronutrient pattern and antioxidative status of gluten-free cookies. The cookies prepared with molasses were significantly higher in potassium, magnesium, calcium, iron, betaine, total phenolics and DPPH radical scavenging abilities. Molasses contributed to wider spectra of phenolic compounds. The dominating phenolic compounds in the molasses-enriched cookies were catechin, ferulic, syringic and vanillic acid. Molasses also contributed to the presence of p-hydroxybenzoic acid in the cookies. Addition of molasses increased the content of hydroxymethyfurfural in the cookies, but not above values commonly reported for this product type. Molasses addition improved the overall acceptance of gluten-free cookies up to 30% enrichment level. PMID:26947667

  13. Technical and economic assessments of storage techniques for long-term retention of industrial-beet sugar for non-food industrial fermentations

    Science.gov (United States)

    Vargas-Ramirez, Juan Manuel

    Industrial beets may compete against corn grain as an important source of sugars for non-food industrial fermentations. However, dependable and energy-efficient systems for beet sugar storage and processing are necessary to help establish industrial beets as a viable sugar feedstock. Therefore, technical and economic aspects of beet sugar storage and processing were evaluated. First, sugar retention was evaluated in whole beets treated externally with either one of two antimicrobials or a senescence inhibitor and stored for 36 wk at different temperature and atmosphere combinations. Although surface treatment did not improve sugar retention, full retention was enabled by beet dehydration caused by ambient air at 25 °C and with a relative humidity of 37%. This insight led to the evaluation of sugar retention in ground-beet tissue ensiled for 8 wk at different combinations of acidic pH, moisture content (MC), and sugar:solids. Some combinations of pH ≤ 4.0 and MC ≤ 67.5% enabled retentions of at least 90%. Yeast fermentability was also evaluated in non-purified beet juice acidified to enable long-term storage and partially neutralized before fermentation. None of the salts synthesized through juice acidification and partial neutralization inhibited yeast fermentation at the levels evaluated in that work. Conversely, yeast fermentation rates significantly improved in the presence of ammonium salts, which appeared to compensate for nitrogen deficiencies. Capital and operating costs for production and storage of concentrated beet juice for an ethanol plant with a production capacity of 76 x 106 L y-1 were estimated on a dry-sugar basis as U.S. ¢34.0 kg-1 and ¢2.2 kg-1, respectively. Storage and processing techniques evaluated thus far prove that industrial beets are a technically-feasible sugar feedstock for ethanol production.

    Chlorophyll content in plant leaves is correlated with the yield and nitrogen content in plants. Non-destructive investigations of chlorophyll content in leaves of 3 varieties of sugar beet grown from seeds revealed that a low frequent magnetic field, acting independently or in combination with other methods of seed improvement, increased chlorophyll content in leaves of the investigated plants. The treatment with the magnetic field increased nitrogen content in the examined plants. The effect was not connected with environmental conditions during vegetation seasons. (author)

  7. Seasonal OVOC fluxes from an agricultural field planted with sugar beet

    Science.gov (United States)

    Custer, T. G.; Schade, G. W.

    2005-12-01

    Although agricultural crops are generally not strong isoprenoid emitters, they do emit a variety of other atmospherically significant species collectively known as oxygenated VOCs (OVOCs), such as methanol, acetaldehyde, or various hexenal and hexenol compounds. Many OVOCs have longer atmospheric lifetimes than isoprenoid compounds and can affect the atmosphere's oxidative potential at higher elevations and far from sources. We performed selected OVOC flux measurements for select species above an agricultural field planted with sugar beets ( B. vulgaris) in northern Germany in 2004 to better understand the magnitude and controls over these OVOC emissions. Virtual disjunct eddy covariance was used to measure fluxes beginning immediately following seeding and continuing until past harvest. A commercial PTR-MS provided mixing ratios of methanol (m/z 33), acetaldehyde (m/z 45), acetone (m/z 59), and the sum of the isoprene oxidation products methacrolein and methyl vinyl ketone (m/z 71) while 3D wind velocities were measured using a Gill R3 sonic anemometer. Here, we compare the fluxes of methanol and acetone over the growth cycle of sugar beet to plant development as measured by the leaf area index. Methanol fluxes ranged from approximately -0.05 to 0.15 mg C m-2 h-1 (mixing ratios from ~1 to 15 ppbv) and showed a clear diurnal cycle after the sugar beets established a significant leaf area. Acetone fluxes ranged from approximately -0.2 to 0.2 mg C m-2 h-1 (mixing ratios from ~0.2 to 3 ppb). Higher specific emissions were found during earlier growth stages. Methanol flux correlated strongly with latent heat flux (or alternatively, with canopy conductance derived from the latent heat flux), while acetone flux did not. Acetone flux was small compared to methanol flux and sugar beet is likely not a significant acetone emitter. Weekly measurements of soil OVOC exchange using a flux chamber showed that the soil may have contributed significantly to the overall flux values

    Biochar converted from agricultural residues or other carbon-rich wastes may provide new methods and materials for environmental management, particularly with respect to carbon sequestration and contaminant remediation. In this study, laboratory experiments were conducted to investigate the removal of phosphate from aqueous solution by biochar derived from anaerobically digested sugar beet tailings (DSTC). Batch adsorption kinetic and equilibrium isotherm experiments and post-adsorption characterizations using SEM-EDS, XRD, and FTIR suggested that colloidal and nano-sized MgO (periclase) particles on the biochar surface were the main adsorption sites for aqueous phosphate. Batch adsorption experiments also showed that both initial solution pH and coexisting anions could affect the adsorption of phosphate onto the DSTC biochar. Of the mathematical models used to describe the adsorption kinetics of phosphate removal by the biochar, the Ritchie N_th-order (N=1.14) model showed the best fit. Two heterogeneous isotherm models (Freundlich and Langmuir-Freundlich) fitted the experimental isotherm of phosphate adsorption onto the biochar better than the Langmuir adsorption model. Our results suggest that biochar converted from anaerobically digested sugar beet tailings is a promising alternative adsorbent, which can be used to reclaim phosphate from water or reduce phosphate leaching from fertilized soils. In addition, there is no need to regenerate the exhausted biochar because the phosphate-laden biochar contains abundance of valuable nutrients, which may be used as a slow-release fertilizer to enhance soil fertility and to sequester carbon.

  11. Molecular characterization of UV-treated sugar beet somaclones using RFLP markers

    International Nuclear Information System (INIS)

    Sugar beet plants regenerated from UV-treated calluses were examined by restriction fragment length polymorphism (RFLP) analysis to determine the extent of somaclonal variation occurring at the DNA level. In total, 50 random sugar beet DNA sequences were used to screen 42 somaclones for genetic alterations. Three polymorphisms were detected among the 7 644 alleles analysed. From these data a mutation frequency of 0.03 ± 0.02% per allele was estimated. This frequency is in agreement with similar studies of somaclonal DNA variation using molecular markers and lies in the upper range of the spontaneous gene mutation frequencies found in plants. The two probegenotype combinations showing independent polymorphisms, were further analysed using the restriction enzymes Bam HI, Eco RI, Eco RV and Hind III. Both polymorphisms are likely to result from structural rearrangements rather than from point mutations. Differences in methylation among 10 of the investigated somaclones were tested for by comparing Hpa II and Msp I generated RFLP patterns. The somaclones showed extensive methylation, but no differences in their degree of methylation. Cytological analysis revealed 34 diploid, 8 tetraploid, but no aneuploid plants. (author)

  12. Anaerobic acidification of sugar-beet processing wastes: Effect of operational parameters

    International Nuclear Information System (INIS)

    The objective of this study was to maximize the hydrolysis and acidification of sugar-beet processing wastewater and beet pulp for volatile fatty acid (VFA) production through acidogenic anaerobic metabolism. Experiments were conducted to determine the optimum operational conditions (HRT, waste-mixing ratio and pH) for effective acidification in daily-fed, continuously mixed anaerobic reactors. For this purpose, reactors were operated at 35 ± 1 C with different combinations of HRT (2-4 days), wastewater-pulp mixing ratios (1:0-1:1, in terms of COD) and pH ranges (5.7-7.5). Increased OLRs, resulting from pulp addition, increased the amount of acidification products (VFAs) which led to relatively low operational pH values (5.7-6.8). In this pH range, methanogenic activity was successfully inhibited and the lowest methane percentages (5.6-16.3%) were observed in the produced biogas. The optimum operational conditions were determined to be 2-day HRT and 1:1 waste mixing ratio (in terms of COD) without external alkalinity addition. These operational conditions led to the highest tVFA concentration (3635 ± 209 mg/L as H-Ac) with the acidification degree of 46.9 ± 2.1%. (author)

  13. Effects of seed irradiation with laser on the yield and chemical composition of sugar beet roots

    International Nuclear Information System (INIS)

    Special attention was paid for presowing seed preparing with the use of laser rays to increase sugar beet yield using economical and environment-safety methods. The field investigations aiming at determination of influence of laser exposure of seeds on biometric features, yielding and some of chemical constitution elements were carried out. The experiments were performed for two varieties and for 0, 1, 2, 3, 4 times laser exposures of seeds with the use of helium-neon HNA-188 laser of power of 40 μW. The exposures were accomplished during free-fall of seeds through divergent laser beam. The investigation results show beneficial effect of laser exposure of seeds on sugar beet yielding. The leaves yield ranged from 35.6 t/ha to 42.0 t/ha. The highest roots yield were obtained after one times seeds exposure (54.6 t/ha). Seed exposure resulted in dry matter increase by 0.1-0.3%, sugar content by 0.1-0.2%, ash by 0.026-0.080%. (author). 12 refs, 1 tab

    Digestive enzymatic activity and nutritional responses of Autographa gamma (L.) (Lepidoptera: Noctuidae), an important insect pest of sugar beet, on nine sugar beet cultivars (Peritra, Karolina, Paolita, Lenzier, Tiller, Ardabili, Persia, Rozier, and Dorothea) were studied. The highest proteolytic activity of fourth and fifth instar of A. gamma was in larvae fed on cultivar Persia. The highest amylolytic activity of fourth and fifth instar was observed in larvae fed on cultivars Rozier and Dorothea, respectively. The lowest proteolytic and amylolytic activities in fourth instar were observed on cultivar Tiller; whereas the lowest activities in fifth instar were detected on cultivars Karolina and Tiller, respectively. Larval weight in both larval instars (fourth and fifth) was the heaviest on cultivar Persia and the lightest on cultivar Karolina. Furthermore, weight gain of larvae was the highest on cultivar Persia and the lowest on cultivar Karolina. The results of this study suggest that cultivar Tiller was the most unsuitable host plant for feeding of A. gamma. PMID:27324581

    Ethanol fermentation of fresh sugar beet mash (SBM) could give a benefit on reducing energy input for sugar diffusion, juice separation, and water evaporation as used in conventional practices, thus offering promise as a low energy process. Actions of cell-wall degrading enzymes provide a mash with low viscosity, which can be easily fermented to ethanol. However, a several-fold higher enzyme loading was required for viscosity reduction of SBM compared with that of potato mash. In this study, the use of dilute alkali treatment (0.025-0.15 N NaOH, 25 C, 1 h) in enhancing enzymatic viscosity reduction of SBM was evaluated. The results showed that higher NaOH concentration enhanced demethylation and deacetylation of SBM, resulting in greater performances of the enzymes on reducing viscosity. Efficient enzymatic viscosity reduction of SBM was observed with the 0.1 N NaOH treatment. On the other hand, untreated SBM was highly resistant to viscosity reduction, even though a 20-fold more enzyme loading was used. The resulting mash containing 12-13% (w/v) sucrose yielded 7-8% (v/v) ethanol after 24 h of fermentation (90% efficiency). Accordingly, alkali treatment can be applied for facilitating the use of fresh sugar beet for ethanol production. (author)

  18. Effect of Extraction Conditions on Quality of Pectin Extracted from Irradiated Sugar Beet Pulp

    International Nuclear Information System (INIS)

    Pectin is used in a number of foods as a gelling agent, thickener, texturizer, emulsifier and stabilizer. Sugar-beet pulp, the residue from sugar industry, is a rich source of pectin. Beet pulp pectin was extracted by using acids under various conditions from ph and temperatures but this method has problems such as pollution and hydrolysis. In this study we avoid these problems by using enzymic pectin (bio extraction). In this method we used different microorganisms tested for their ability to produce proto pectin-solubilizing enzymes. Bacillus subtilis and Pichia polymorphia. Chemical components of the extracted pectin were determined and compared, and study the quality of pectin under different conditions of ph, period of incubation and age of inoculum, also the quantity of pectin extracted by incubation with Bacillus, and Pichia were study. The results show that the best conditions were at ph 6, at the optimum period incubation 8-16 h and 24 h age of inoculum. The best yield of pectin obtained by Pichia polymorphia without Bacillus subtilis

    Full Text Available Cercospora leaf spot disease (Cercospora beticola Sacc., is one of the most economically important fungal diseases in sugar beet growing. Under appropriate climatic conditions, the disease can reach epidemic levels. Although some fungicides exist for disease control, resistance development by pathogen against fungicides is creating difficulties. Besides, use of resistant varieties which is considered as the most efficient and environment-friendly method is adversely affected by pathogen’s ability to exhibit high genetic variations and varying resistance levels against different races of pathogen restricts the success of resistance breeding studies. In order to reveal status of this disease in Kayseri province, surveys were conducted in 2010 and 2011 in sugar beet growing areas and disease prevalence and severity were determined. Approximately, 1500 da area in 90 fields were examined and about 700 da of this area found as infected with Cercospora leaf spot disease in both years of the survey. Highest disease prevalence and severity were found as 80 % and 45 %, respectively, in Sarıoğlan district, which is followed by central district, Develi and Bünyan. Among surveyed districts, lowest prevalence and severity were detected as approx. 65 % and 35 %, respectively, in Yeşilhisar.

    Beet necrotic yellow vein virus (BNYVV) is a serious threat to the sugar beet industry worldwide. However, little information is available regarding the genetic diversity and population structure of BNYVV in China. Here, we analyzed multiple sequences from four genomic regions (CP, RNA3, RNA4 and RNA5) of a set of Chinese isolates. Sequence analyses revealed that several isolates were mixed infections of variants with different genotypes and/or different p25 tetrad motifs. In total, 12 distinct p25 tetrads were found in the Chinese BNYVV population, of which four tetrads were newly identified. Phylogenetic analyses based on four genes (CP, RNA3-p25, RNA4-p31 and RNA5-p26) in isolates from around the world revealed the existence of two to four groups, which mostly corresponded to previously reported phylogenetic groups. Two new subgroups and a new group were identified from the Chinese isolates in p25 and p26 trees, respectively. Selection pressure analysis indicated that there was a positive selection pressure on the p25 from the Chinese isolates, but the other three proteins were under a negative selection pressure. There was frequent gene flow between geographically distant populations, which meant that BNYVV populations from different provinces were not geographically differentiated. PMID:25997927

  2. Anaerobic acidification of sugar-beet processing wastes: Effect of operational parameters

    International Nuclear Information System (INIS)

    The objective of this study was to maximize the hydrolysis and acidification of sugar-beet processing wastewater and beet pulp for volatile fatty acid (VFA) production through acidogenic anaerobic metabolism. Experiments were conducted to determine the optimum operational conditions (HRT, waste-mixing ratio and pH) for effective acidification in daily-fed, continuously mixed anaerobic reactors. For this purpose, reactors were operated at 35 ± 1 oC with different combinations of HRT (2-4 days), wastewater-pulp mixing ratios (1:0-1:1, in terms of COD) and pH ranges (5.7-7.5). Increased OLRs, resulting from pulp addition, increased the amount of acidification products (VFAs) which led to relatively low operational pH values (5.7-6.8). In this pH range, methanogenic activity was successfully inhibited and the lowest methane percentages (5.6-16.3%) were observed in the produced biogas. The optimum operational conditions were determined to be 2-day HRT and 1:1 waste mixing ratio (in terms of COD) without external alkalinity addition. These operational conditions led to the highest tVFA concentration (3635 ± 209 mg/L as H-Ac) with the acidification degree of 46.9 ± 2.1%.

  3. Evidence for the presence of a sucrose carrier in immature sugar-beet roots

    International Nuclear Information System (INIS)

    Unlike in mature sugar-beet roots, sucrose is assumed to be hydrolyzed by a wall-bound invertase prior to uptake by immature roots. To test this hypothesis, they used a sucrose analog, 1'fluorosucrose which is recognized by the carrier but is a poor substrate for invertases. Asymmetrically labeled sucrose (3H-fructose) 1'fluorosucrose (14C-glucose) were applied at 10 mM (3H/14C=1) to an attached source leaf. After 6 h, sugars from plant parts in the translocation path were separated on HPLC. 14C-1'fluorosucrose was translocated and accumulated in the root at a higher rate than 3H-sucrose due to greater metabolism of 3H-sucrose in the shoot (indicated by the presence of 3H in hexose fractions and loss of asymmetry). In the root 25% of the 3H-sucrose was hydrolyzed to hexoses whereas no 14C was detected in hexose fractions. The data indicate that despite high cell-wall invertase and cytoplasmic sucrose synthase activities, young sugar-beet roots import and store sucrose without hydrolysis. Therefore, the function of a group translocator at the tonoplast is unclear

  5. Induction of cytoplasmic male sterility by gamma-ray and chemical mutagens in sugar beets

    International Nuclear Information System (INIS)

    Male sterile plants appeared in the population of N cytoplasm sugar beet strains, H-19 and H-2002, when their dry seeds were exposed to 50 kR gamma-ray, and the male sterility was maintained up to the M4 generation through the mother plants. Cytoplasmic inheritance was confirmed by the reciprocal crossings between plants with normal phenotype from gamma-strains (progeneis of the male mutants which transmitted male sterility through the mother plants) and H-19 or H-1001. The crossing experiments suggested that various kinds of cytoplasm were induced by gamma-ray irradiation, and that different nuclear genes were responsible for the respective cytoplasms. A specific relationship between the pollen restoring genes and the sterile cytoplasms was established, and was named ''one set of pollen restoring genes for one cytoplasm''. It is probable that the cytoplasmic mutation occurred in normal cytoplasm strains and the specific combination between the altered cytoplasm and the recessive nuclear gene produced male sterility. Ethyl methane sulphonate, ethidium bromide, acriflavine and streptomycin were also effective in inducing cytoplasmic mutation in sugar beets. (Kaihara, S.)

    The effect of Liquid Hot Water treatment conditions on the degree of sugar beet pulp (SBP) degradation was studied. The SBP was subjected to hydrothermal processing at temperatures ranging from 120 to 200 °C. The relationship between processing temperature and parameters of liquid and solid fractions of resulting hydrolysates as well as the efficiency of their methane fermentation was determined. The highest concentration of free glucose (3.29 mg ml(-1)) was observed when the hydrolysis was conducted at 160 °C (it was 4-fold higher than that after processing at 120 °C). Total acids and aldehydes concentrations in the liquid fractions were increased from 0.005 mg ml(-1) for the untreated SBP to 1.61 mg ml(-1) after its processing at 200 °C. Parameters of the hydrolysates obtained by the LHW treatment decided of the efficiency of methane fermentation. The highest cumulative methane yield (502.50 L CH₄ kg(-1)VS) was obtained from the sugar beet pulp hydrolysate produced at 160 °C. PMID:24907578

    Levan, a type of fructan, is an oligomer or polymer with mainly a β(2,6)-linked fructose chain attached to sucrose. We introduced two timothy genes, PpFT1 and PpFT2, coding for two homologous sucrose:fructan 6-fructosyltransferases into sugar beet. Sugar beet produces a high concentration of sucrose, a starting substrate in fructan synthesis, in the root. Among transgenic T1 lines, we obtained sugar beet transformants that accumulated large amounts of β(2,6)-linked levans (about 20 to 75mgg(-1) FW) in the roots. The transformed sugar beet plants possessing PpFT1 or PpFT2 produced linear levans with different degrees of polymerization (DP). Namely, the PpFT1 transformants accumulated mainly high DP levans including those with DP>40, while the PpFT2 transformants accumulated levans with DP between 3 and 40. Chromatograms showed that PpFT2 produces pure β(2,6)-linked linear levans compared with fructans synthesized by PpFT1. These levans belong to the high DP class of plant fructans, but have much shorter DP than that of levans generally produced by microorganisms. PMID:25305472

    Yellow and red-violet betalain plant pigments are restricted to several families in the order Caryophyllales, where betacyanins play analogous biological roles to anthocyanins. The initial step in betalain biosynthesis is the hydroxylation of tyrosine to form L-DOPA. Using gene expression experiments in beets, yeast, and Arabidopsis, along with HPLC/MS analysis, the present study shows that two novel cytochrome P450 (CYP450) enzymes, CYP76AD6 and CYP76AD5, and the previously described CYP76AD1 can perform this initial step. Co-expressing these CYP450s with DOPA 4,5-dioxygenase in yeast, and overexpression of these CYP450s in yellow beets show that CYP76AD1 efficiently uses L-DOPA leading to red betacyanins while CYP76AD6 and CYP76AD5 lack this activity. Furthermore, CYP76AD1 can complement yellow beetroots to red while CYP76AD6 and CYP76AD5 cannot. Therefore CYP76AD1 uniquely performs the beet R locus function and beets appear to be genetically redundant for tyrosine hydroxylation. These new functional data and ancestral character state reconstructions indicate that tyrosine hydroxylation alone was the most likely ancestral function of the CYP76AD alpha and beta groups and the ability to convert L-DOPA to cyclo-DOPA evolved later in the alpha group.

    Full Text Available Rhizoctonia solani (Kühn is one of the most important sugar beet pathogens Rhizoctonia solani anastomosis groups (AGs 2-2 and 4 are proven to be the most common pathogenic strains on sugar beet. AG 2-2 (intraspecific groups IIIB and IV can cause root and crown rot while damping-off of seedlings is most frequently attributed to AG 4. Four isolates of R. solani from sugar beet roots showing characteristic crown and root rot symptoms, collected from different localities in Vojvodina Province, were chosen and compared to the well-characterized R. solani isolate R9, AG 2-2 IV, from the USA. All Vojvodinian isolates showed medium level of pathogenicity and were able to cause crown and root rot symptoms on inoculated sugar beet roots. Based on anastomosis reaction, isolates from Vojvodina did not belong to the AG 2-2 group. Sequencing of the ITS (internal transcribed spacer region of ribosomal DNA was performed on the Vojvodinian isolates from R9 in order to determine their relatedness. Sequence analysis showed that these isolates were different than R9 and were closely related (99-100% sequence homology to anastomosis group 4, subgroup HG II.

    Sugar beet root rot diseases that occur during the cropping season or in storage are accompanied by high yield losses and a severe reduction of processing quality. The vast diversity of microorganism species involved in rot development requires molecular tools allowing simultaneous identification of many different targets. Therefore, a new microarray technology (ArrayTube) was applied in this study to improve diagnosis of sugar beet root rot diseases. Based on three marker genes (internal transcribed spacer, translation elongation factor 1 alpha, and 16S ribosomal DNA), 42 well-performing probes enabled the identification of prevalent field pathogens (e.g., Aphanomyces cochlioides), storage pathogens (e.g., Botrytis cinerea), and ubiquitous spoilage fungi (e.g., Penicillium expansum). All probes were proven for specificity with pure cultures from 73 microorganism species as well as for in planta detection of their target species using inoculated sugar beet tissue. Microarray-based identification of root rot pathogens in diseased field beets was successfully confirmed by classical detection methods. The high discriminatory potential was proven by Fusarium species differentiation based on a single nucleotide polymorphism. The results demonstrate that the ArrayTube constitute an innovative tool allowing a rapid and reliable detection of plant pathogens particularly when multiple microorganism species are present.

    Full Text Available The purpose of the research was to characterize the effect of the pre-sowing laser biostimula-tion of sugar beet seeds on the biometric features, yielding and chemical composition of sugar beet roots. Four varieties of sugar beets were studied: Colibri, Evita, Kawetina, and Maria. Their seeds were biostimulated during free falling with divergent He-Ne laser beams (40 mW, placed one upon another. The experiments were conducted ace. to the split-plot method in 3 repetitions. Before the harvesting, 20 plants were measured biometrically for the length of leaves, weight of leaves, sticking out of roots over the surface of soil, length, weight, diameter, and circumference of roots. During the harvest, the yield of roots and leaves was specified and after the harvest the chemical analysis was made to check the plant dry mass, the content of sugar, soluble ash, alpha-amine nitrogen, P, K, Ca, Mg, Na, Fe, Zn, Mn, Cu. The results of the research showed beneficial effects of the laser pre-sowing stimulation of sugar beet seeds. In all the combinations concerning the biostimulated seeds, the yield of roots was elevated from 3,2 to 4,5 t/ha, which means an 8-10 % increase when compared to the control (non-biostimulated seeds. The sugar content was also elevated after the laser biostimulation, which caused an increase in the biological yield for about 1 t/ha independently of the variety in comparison with the control.

    Consumption of vegetables grown in arsenic (As)-contaminated soils is an important exposure route to the element for humans. The present study is focused on locally-grown, frequently-consumed vegetables, such as carrots (Daucus carota), beets (Beta vulgaris) and quinoa (Chenopodium) from the As-polluted Chiu Chiu area in Northern Chile. The latter region is affected both by As discharge from copper mining activity and natural As contamination, leading to a high As content in local food and water. For the selected vegetables, the following aspects were investigated: i) Their total As, Cu, Pb, Cr, Cd and Mn content; ii) Arsenic speciation in the edible part of the vegetables by liquid chromatography inductively-coupled plasma mass spectrometry (LC-ICPMS) analysis; iii) Arsenic bioaccessibility in the vegetables during in vitro gastrointestinal digestion; iv) Arsenic species present in the extracts obtained from in vitro gastrointestinal digestion; and v) Arsenic dietary exposure estimates for the assessment of the risk posed by the vegetables consumption. A significant degree of As contamination was found in the vegetables under study, their metal content having been compared with that of similar Spanish uncontaminated products. In vitro gastrointestinal digestion of the studied vegetables led to quantitative extraction of As from carrots and beets, whereas efficiency was about 40% for quinoa. For carrots, only As(III) and As(V) species were found, being their concentration levels similar. In the case of quinoa, around 85% of the element was present as As(V). For beets, inorganic As(V) and unknown overlapped As species (probably arsenosugars) were found. No significant transformation of the original As species was observed during in vitro gastrointestinal digestion. Arsenic dietary exposure values obtained for the three vegetables (0.017-0.021μg As person(-1)day(-1)) were much lower than the JFCFA's safety limit of 50μg As person(-1)day(-1). Therefore, no

    Full Text Available Rhizomania is one of the most important diseases of sugar beet around the world – including in Iran. The disease causes a severe decrease in sugar yield and is a limiting factor in sugar beet cultivation. Control of the disease is very difficult due to the long-term survival of its fungal vector (Polymyxa betae in the soil. In this study, we investigated the effects of antagonistic fungal isolates on the population of the resting structure (cystosorus of P. betae, under greenhouse conditions. Antagonistic fungi, including Trichoderma harzianum and Talaromyces flavus, were isolated from soil samples collected from sugar beet infested fields in the Semnan Province of Iran. In the next step, their inocula were prepared through reproduction on rice bran. For evaluation of the efficacy of antagonists in greenhouse conditions, a split plot trial was conducted and performed. The main factor was three different methods of application of T. flavus as the soil treatment, seed treatment, and a combination of both methods. The sub-factor was the use of different fungal isolates. To determine the cystosorus population of the fungal vector, seedling roots in all treatments were stained with lactic acid and fuchsine (lactofushine, 60 days after sowing. The number of cystosorus in one gram of root was counted using a light microscope and hemocytometer. At the end of the study, average root weight in different treatments was also measured to select and introduce the best treatments in regard to their effects on root weight. According to the results, the number of cystosorus in 1 g of root was different in various treatments and those treatments containing TF-Su-M-1, TF-Su-M-2, TH-Su-M-1, and TH-Su-M-2 used as a soil application method were more effective in the reduction of the cystosorus population and root weight increase. Among the above-mentioned treatments, maximum reduction of cystosori population and the increase in root weight were observed in TH

  5. Induction of betalain pigmentation in hairy roots of red beet under different radiation sources

    International Nuclear Information System (INIS)

    The effect of different radiation sources - blue (B), red (R), R plus B (RB), B plus far red (BFr), R plus far red (RFr) - was tested on the growth of hairy roots and betalain accumulation in Beta vulgaris (red beet). Light emitting diodes were used as radiation sources. The growth of hairy roots under different radiation treatments depended on radiation quality. Highest biomass accumulation was under the BFr treatment. BFr treatment efficiently induced betalain pigmentation in hairy roots. Total sugar and sucrose concentrations of hairy roots were also greater in this treatment. Thus, the betalain pigmentation in the cultured hairy roots can be influenced by radiation quality and BFr is most suitable for accumulation of betalains. (author)

    Cellulose nanofibers (diameter=10-70 nm) were produced using chemical treatments (alkali treatment and bleaching) and high pressure homogenization from de-pectinated sugar beet pulp (DSBP). Chemical analysis and Fourier transform infrared spectroscopy (FTIR) indicated that the chemical treatments greatly removed the hemicellulose and lignin from the DSBP and significantly increased the cellulose content. The crystallinity of the cellulose nanofibers increased from 35.67% to 69.62% after alkali treatment and bleaching. The thermal degradation temperature of DSBP cellulose nanofibers was 271.7 °C which was found to be 47.3 °C higher than that of the untreated DSBP. The DSBP cellulose nanofibers can be preferably used as reinforcement in the biocomposite material at high temperature. PMID:24507265

    Three pectic oligosaccharides (POS) obtained by enzymatic hydrolysis of sugar beet pectin by combining endopolygalacturonase and pectinmethylesterase, were characterized using high performance liquid chromatography, thermogravimetric analysis, Fourier transform infrared spectroscopy, differential scanning calorimetry and X-ray diffraction. According to chromatographic analyses, POS are composed of mixture of polymers with different molecular weights and different galacturonic acid contents. The thermal analysis showed no major variation in thermal behavior regarding POS composition but showed that POS were more sensitive to thermal degradation than the parent pectin as well as the deesterified pectin. No change in composition of the gaseous products was obtained through TGA-FTIR analysis. The X-ray pattern of POS clearly indicated a considerable decrease in crystallinity when compared to the native pectin. Thus, thermal characterization of POS may have practical repercussions if the formulation in which POS is incorporated is submitted to a high temperature treatment. PMID:22986181

  8. Citric acid production by gamma irradiated aspergillus niger from treated beet molasses under different fermentation conditions

    International Nuclear Information System (INIS)

    The necessary treatments of beet molasses by addition of any the chelating agents potassium ferrocyanide and ethylenediamine tetraacetic acid (EDTA), to improve its suitability as a substrate for citric acid production by gamma irradiated inocula (at dose 0.4 KGy) of aspergillus niger EMCC 111 was studied. Addition of potassium ferrocyanide stimulated citric acid production and maximum production (10.92 g%) was obtained with 0.1 g% of ferrocyanide. In contrast, EDTA at 0.1 g% increased citric acid production but further addition of EDTA repressed the production. Addition of low molecular weight alcohols (methanol or ethanol)improved the yield of citric acid. Methanol and ethanol when added at concentration of 2%(v/v) elevate citric acid yield % to 47.58% and 46.51% respectively. 6 tabs

    Molasses, the main byproduct of sugar production, is a well-known source of antioxidants. In this study sugar cane molasses (SCM) and sugar beet molasses (SBM) were investigated for their phenolic profile and in vitro antioxidant capacity and for their protective effect in human HepG2 cells submitted to oxidative stress. According to its higher phenolic concentration and antioxidant capacity in vitro, SCM exhibited an effective protection in cells, comparable to or even greater than that of α-tocopherol. Data herein reported emphasize the potential health effects of molasses and the possibility of using byproducts for their antioxidant activity. This is particularly important for consumers in developing countries, as it highlights the importance of consuming a low-price, yet very nutritious, commodity. PMID:23190112

  10. Molecular size estimation of plasma membrane β-glucan synthase from red beet root

    International Nuclear Information System (INIS)

    Cellulose and cell wall β-D-glucans in higher plants are thought to be synthesized by the plasma membrane enzyme, β-glucan synthase. This enzyme has never been purified to homogeneity, hence its subunit composition is unknown. Partial purification of red beet root glucan synthase by glycerol density gradient centrifugation followed by SDS-PAGE yielded a highly enriched subunit of 68 kDa. Radiation inactivation of plasma membranes gave a molecular size the 450 kDa for the holoenzyme complex. This suggests that glucan synthase consists of 6 to 7 subunits and confirms electron microscope studies showing that glucan synthases exist as multi-subunit complexes embedded within the membrane

  11. Field estimation of the utilization coefficient of added inorganic nitrogen by sugar-beets

    International Nuclear Information System (INIS)

    Fertilization with mineral nitrogen labelled with the 15 isotope permits, in the crop, the estimation of both: - the real utilization coefficient of N fertilizer, - the uptake of the available N issued from organic matter. In 1979, such an experiment was carried out on sugar beet in Beauce on a long term field experiment including 7 N.P.K. treatments with 4 repetitions. Each plot was divided into 2 parts to constitute a treatment N=0 for the estimation of the apparent utilization coefficient. In addition, 4 microplots (size: 8 m2) received a labelled fertilizer for the measurement of the actual coefficients. The results obtained show the incoherence of the apparent coefficients, which are higher than 100%. The real coefficients are from 40 to 80%. Thus, the balance sheet for the input and output of mineral nitrogen is established precisely. The gross mineralization can be much more important than the net mineralization

  12. The effect of glyphosate on import into a sink leaf of sugar beet

    International Nuclear Information System (INIS)

    The basis for glyphosate inducted limitation of carbon import into developing leaves was studied in sugar beet. To separate the effects of the herbicide on export from those on import, glyphosate was supplied to a developing leaf from two exporting source leaves which fed the sink leaf. Carbon import into the sink leaf was determined by supplying 14CO2 to a third source leaf which also supplies carbon to the monitored sink leaf. Import into the sink leaf decreased within 2 to 3 h after glyphosate application, even though photosynthesis and export in the source leaf supplying 14C were unaffected. Reduced import into the sink leaf was accompanied by increased import by the tap root. Elongation of the sink leaf was only slightly decreased following arrival of glyphosate. Photosynthesis by the sink leaf was not inhibited. The results to data support the view that import is slowed by the inhibition of synthesis of structural or storage compounds in the developing leaves

  13. Effect of pre-planting irradiation of seeds on the sugar beet yield

    International Nuclear Information System (INIS)

    Pre-planting seed treatment with gamma-rays as affecting both the beet yield and sugar content was studied. Air-dried germinative seeds of the Beta poly 3 and Yaltoush monogerm varieties were irradiated with gamma-rays in total doses of 1000 to 4000 R. After treatment the seeds were planted in a check board trial with six replications. Results show that pre-planting irradiation of seed with stimulating doses of gamma-rays does not substantially affect the sugar output. Differences in yields of untreated and treated olants are mathematically not proved. One and the same dose of rays produces a different effect in different years which is dependent on the conditions of irradiation and plant growing. Variable results of pre-planting seed irradiation make this method unsuitable in view of the number of external factors for which there is no control. (M.Ts.)

    Effects of precipitation modes on the co-precipitation of insoluble oxalates particles during the purification of sugar beet pectins (SBP) from the extract were investigated. It was observed that soluble oxalate ions formed insoluble oxalate salts with calcium and precipitated with pectins during ethanol precipitation as pH of the medium increased and the solvent changed from water to ethanol-water mixture. Comparison among the employed precipitation methods revealed that both the dialysis-ethanol-precipitation and metal precipitation effectively prevented the calcium-oxalate contamination of SBP. Emulsifying properties of DEPP, EPP and MPP were also studied. It was observed that DEPP performed better than the remainder with respect to emulsifying ability. Based on these results, we concluded that the dialysis-ethanolic-precipitation can be a suitable method for improving the purity as well as emulsifying properties of the resulting pectins.

    This study was performed to assess the feasibility of producing fuel ethanol from sugar beets. Sugar beets are a major agricultural crop in the area and the beet sugar industry is a major employer. There have been some indications that increasing competition from imported sugar and fructose sugar produced from corn may lead to lower average sugar prices than have prevailed in the past. Fuel ethanol might provide an attractive alternative market for beets and ethanol production would continue to provide an industrial base for labor. Ethanol production from beets would utilize much of the same field and plant equipment as is now used for sugar. It is logical to examine the modification of an existing sugar plant from producing sugar to ethanol. The decision was made to use Great Western Sugar Company's plant at Mitchell as the example plant. This plant was selected primarily on the basis of its independence from other plants and the availability of relatively nearby beet acreage. The potential feedstocks assessed included sugar beets, corn, hybrid beets, and potatoes. Markets were assessed for ethanol and fermentation by-products saleability. Investment and operating costs were determined for each prospective plant. Plants were evaluated using a discounted cash flow technique to obtain data on full production costs. Environmental, health, safety, and socio-economic aspects of potential facilities were examined. Three consulting engineering firms and 3 engineering-construction firms are considered capable of providing the desired turn-key engineering design and construction services. It was concluded that the project is technically feasible. (DMC)

    Full Text Available The beet cyst nematode, Heterodera schachtii, is a major root pest that significantly impacts the yield of sugar beet, brassicas and related species. There has been limited molecular characterisation of this important plant pathogen: to identify target genes for its control the transcriptome of the pre-parasitic J2 stage of H. schachtii was sequenced using Roche GS FLX. Ninety seven percent of reads (i.e., 387,668 with an average PHRED score > 22 were assembled with CAP3 and CLC Genomics Workbench into 37,345 and 47,263 contigs, respectively. The transcripts were annotated by comparing with gene and genomic sequences of other nematodes and annotated proteins on public databases. The annotated transcripts were much more similar to sequences of Heterodera glycines than to those of Globodera pallida and root knot nematodes (Meloidogyne spp.. Analysis of these transcripts showed that a subset of 2,918 transcripts was common to free-living and plant parasitic nematodes suggesting that this subset is involved in general nematode metabolism and development. A set of 148 contigs and 183 singletons encoding putative homologues of effectors previously characterised for plant parasitic nematodes were also identified: these are known to be important for parasitism of host plants during migration through tissues or feeding from cells or are thought to be involved in evasion or modulation of host defences. In addition, the presence of sequences from a nematode virus is suggested. The sequencing and annotation of this transcriptome significantly adds to the genetic data available for H. schachtii, and identifies genes primed to undertake required roles in the critical pre-parasitic and early post-parasitic J2 stages. These data provide new information for identifying potential gene targets for future protection of susceptible crops against H. schachtii.

    Full Text Available Abstract Background Sugar beet is an obligate outcrossing species. Varieties consist of mixtures of plants from various parental combinations. As the number of informative morphological characteristics is limited, this leads to some problems in variety registration research. Results We have developed 25 new microsatellite markers for sugar beet. A selection of 12 markers with high quality patterns was used to characterise 40 diploid and triploid varieties. For each variety 30 individual plants were genotyped. The markers amplified 3-21 different alleles. Varieties had up to 7 different alleles at one marker locus. All varieties could be distinguished. For the diploid varieties, the expected heterozygosity ranged from 0.458 to 0.744. The average inbreeding coefficient Fis was 0.282 ± 0.124, but it varied widely among marker loci, from Fis = +0.876 (heterozygote deficiency to Fis = -0.350 (excess of heterozygotes. The genetic differentiation among diploid varieties was relatively constant among markers (Fst = 0.232 ± 0.027. Among triploid varieties the genetic differentiation was much lower (Fst = 0.100 ± 0.010. The overall genetic differentiation between diploid and triploid varieties was Fst = 0.133 across all loci. Part of this differentiation may coincide with the differentiation among breeders' gene pools, which was Fst = 0.063. Conclusions Based on a combination of scores for individual plants all varieties can be distinguished using the 12 markers developed here. The markers may also be used for mapping and in molecular breeding. In addition, they may be employed in studying gene flow from crop to wild populations.

  7. Comparing application methods for N-fertilizer in the sugar beet crop

    Full Text Available Sugar beet seeders have been developed in other countries, in order to place nitrogen into the soil at a few centimeters from the seed. Placing fertilizer has proved safe for seedling emergence, successful in reducing soil residual nitrogen at harvest, sometimes even better-yielding than broadcast applications. In a 3-year research on sugar beet, spreading fertilizer on the soil surface followed by incorporation was compared with placing in rows 6 and 3 cm far from the seed ones, slightly deeper than the seed, in combination with two rates of urea-N, 60 and 120 kg ha-1, plus an unfertilized check. The course of soil mineral nitrogen and that of N-uptake were evaluated during crop cycle. Yield and quality were evaluated at harvest. Nitrogen placement close to the seed (3 cm negatively affected crop emergence. In the plant-soil system, placement showed a higher soil N-content in the first phases and a lower plant uptake at harvest. As for yield, placement attained a slightly-lower level than broadcasting at 60 kg N ha-1 of N, almost the same at 120. No significant difference in quality was observed between the two patterns. At a certain distance from the seed, placement proved a safe way of applying fertilizer. Its yield and quality, the uptake by the plant and the amount of soil residual-N are comparable with those of broadcast fertilizer; in the case of soil nitrogen, it is perceived that the year/location effect is potentially stronger than that of rate/pattern of application.

  8. Selection in vitro for UV-tolerant sugar beet (Beta vulgaris) somaclones

    With a reduced stratospheric ozone concentration, the generation of UV-tolerant plants may be of particular importance. Among different crop plants there is large variation in sensitivity to UV-B radiation. This study was undertaken to investigate the possibilities of using somaclonal variation and selection in vitro for improving UV-B tolerance in sugar beet (Beta vulgaris L.). Sugar beet callus was exposed to UV radiation (280–320 nm, 0.863–5.28 kJ m-2 day-1, unweighted) and resultant shoots were selected from surviving cells. After establishment of the plants, they were grown under either visible radiation (114 μmol m-2 s-1 PAR) or with the addition of UV radiation (6.3 kJ m-2 day-1 biologically effective UV-B). Screening of regenerants in vivo for tolerance to UV radiation was undertaken 10 months after termination of the UV selection pressure. Screening was done visually and by using a number of physiological parameters, including chlorophyll fluorescence induction, ultraweak luminescence, pigment analysis and total content of UV-screening pigments. A clear difference between the unselected and the UV-selected somaclones was observed when visually studying the UV damage and other leaf injury. The observations were supported by the ultraweak luminescence measurements. Unselected plants showed significantly greater damage when subjected to subsequent UV radiation as compared to the selected plants. The clones subjected to UV selection pressure displayed a significantly higher concentration of UV-screening pigments under subsequent UV radiation. The unselected plants under subsequent UV treatment showed a lower carotenoid concentration when compared to selected plants. However, no significant difference between treatments was found for chlorophyll a/b, or F/Fmax, a measure of photosynthetic quantum yield

  9. Characteristics and mechanisms of hexavalent chromium removal by biochar from sugar beet tailing

    International Nuclear Information System (INIS)

    Highlights: → Biochar from sugar beet tailing effectively removed Cr(VI) from solution. → Most of the Cr on the biochar was Cr(III). → Cr(VI) removal was via electrostatic attraction to biochar. → Reduction of Cr(VI) to Cr(III) ion and complexation between Cr(III) ion and biochar function groups were also important. → The maximum sorption capacity of biochar for Cr(VI) was123 mg/g. - Abstract: Removal of Cr(VI) from aqueous solutions using biochar from sugar beet tailing (SBT) was investigated as a function of pH, contact time, and biochar mass via batch experiments. The surface characteristics of SBT biochar before and after Cr(VI) sorption was investigated with scanning electron microscopy equipped with energy dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. Desorption and X-ray photoelectron spectroscopy studies showed that most of the Cr bound to SBT biochar was Cr(III). These results indicated that the electrostatic attraction of Cr(VI) to positively charged biochar surface, reduction of Cr(VI) to Cr(III) ion, and complexation between Cr(III) ion and SBT's function groups were probably responsible for Cr(VI) removal by SBT biochar. An initial solution with a pH of 2.0 was most favorable for Cr(VI) removal. The sorption process can be described by the pseudo-second order equation and Langmuir isotherm. The maximum sorption capacity for Cr(VI) was 123 mg/g under an acidic medium, which was comparable to other low-cost sorbents.

    + pyraclostrobin. According to IPM guidelines, fungicides in Denmark are presently recommended to be applied if a severity threshold of 5 % is exceeded, the first application normally around August the 1st. The second application is performed when new infections are observed with threshold 5-10 %. Typically 25......-50% of the commonly used fungicide dose is recommended for each treatment. Preliminary field trials have indicated a more efficient control of fungal diseases and higher sugar yield if sugar beets are treated with fungicides before visual symptoms occur. For a better determination of the optimized timing...... of disease control, more advanced methods are needed. In collaboration between the Universities of Copenhagen and Aarhus and the R&D enterprise Nordic Beet Research (NBR) a study was conducted with the goals a) to develop an early detection system based on spore trapping and b) to develop a real...

    Two fumonisin-nonproducing strains of Fusarium verticillioides and their fumonisin producing progenitors were tested for aggressiveness toward maize, sorghum, rice, and beetroot seedlings grown under greenhouse conditions. None of the plants showed obvious disease symptoms after root dip inoculation. Fungal biomass was determined by species-specific real-time PCR. No significant (P = 0.05) differences in systemic colonization were detected between the wild type strains and mutants not producing fumonisins. F. verticillioides was not detected in any of the non-inoculated control plants. The fungus grew from roots to the first two internodes/leaves of maize, rice and beet regardless of fumonisin production. The systemic growth of F. verticillioides in sorghum was limited. The results showed that fumonisin production was not required for the infection of roots of maize, rice and beet by F. verticillioides. PMID:26672472

  13. Combined Influence of Extraction Parameters on Degree of Esterification of Sugar Beet Pulp Pectin: A Preliminary Study

    International Nuclear Information System (INIS)

    A Box-Behnken design was employed to study the combined effects of variables of microwave-assisted extraction on pectin from sugar beet pulp. The independent variables were time and power of microwave-assisted extraction, pH of sulfuric acid and rate of solid to liquid (SLR). The combined effects of these variables on degree of esterification (DE) were studied. Results have shown that the generated regression model significantly explained the actual relationship between the independent variables and response. Besides that, pH was the most important variable which affected the DE. Higher acid concentration, extraction power and longer extraction time increased the DE of pectin due to Esterification. Through the response surface, the satisfactory conditions for extraction of high-ester sugar beet pulp pectin were obtained as follows: 1.02 of pH, 3.96 min of extraction time, 193.68W of power and 19.98 of SLR.

    An integrated dark fermentation and microbial electrochemical cell (MEC) process was evaluated for hydrogen production from sugar beet juice. Different substrate to inoculum (S/X) ratios were tested for dark fermentation, and the maximum hydrogen yield was 13% of initial COD at the S/X ratio of 2 and 4 for dark fermentation. Hydrogen yield was 12% of initial COD in the MEC using fermentation liquid end products as substrate, and butyrate only accumulated in the MEC. The overall hydrogen production from the integrated biohydrogen process was 25% of initial COD (equivalent to 6 mol H2/mol hexoseadded), and the energy recovery from sugar beet juice was 57% using the combined biohydrogen.

    Metabolism of chiral pesticides in crops is typically studied using achiral analytical methods and, consequently, the stereoisomer composition of residues is unknown. In this study, we developed an enantioselective GC-MS/MS method to quantify residues of the fungicides fenpropidin, fenpropimorph, and spiroxamine in plant matrices. In field trials, the fungicides were applied to grapevines, sugar beets, or wheat. Fenpropidin was metabolized with no or only weak enantioselectivity. For fenpropimorph, slightly enantioselective metabolism was observed in wheat but more pronounced in sugar beets. This enantioselectivity was due to different rates of metabolism and not due to interconversion of enantiomers. The four stereoisomers of spiroxamine were also metabolized at different rates, but selectivity was only found between diastereomers and not between enantiomers. trans-Spiroxamine was preferentially degraded in grapes and cis-spiroxamine in wheat. These findings may affect the consumer dietary risk assessment because toxicological end points were determined using racemic test substances. PMID:27248479

    2016-01-01

    Sugar beet (Beta vulgaris cv. Beta 356) was subjected to drought stress during vegetative development by maintaining the soil water content in the 0-40 cm soil depth at 70%, 50% or 30% of field capacity to study the physiological traits of the leaves. Results showed that the compensation index was the highest in the 50% field capacity treatment. Malonaldehyde (MDA) content, relative conductivity, catalase (CAT) activity, and soluble sugar content began to increase 24 h after rehydration. Proline content began to increase 48 h after rehydration. In contrast, no compensation effect was observed in peroxidase (POD) activity after rehydration. Among the active oxygen scavenging enzymes, CAT was most sensitive to drought stress. Supplemental irrigation should be carried out promptly when the soil water content dropped to 50% of field capacity during vegetative development. Rehydration could promote self-repair functions in leaves, thus reducing the effects of drought on sugar beet yield and sugar content. PMID:27228610

    In this article, the selection of tebufenozide to beet armyworm (Spodoptera exigua Hubner) was studied by the treatments to alternative generations' 3rd-instar larvae with LC50 dose and to continuous generations' larvae with LC10 dose; the effects of tebufenozide on the biological characteristics of current and subsequent generations were examined by the treatments to 3rd-instar larvae and egg pods in different concentrations. After treatments with LC50 dose till F11, the toxicity of tebufenozide to beet armyworm had no significant change, whereas the pupation rate, pupal weight, and fecundity were reduced markedly. After treatments with LC10 dose till F19, the beet armyworm only developed 3.52-fold resistance, and the main biological characteristics were nearly accordant in each generation. The livability was reduced 72 h later after treatments to 3rd-instar larvae, respectively in 2.5-40 (ig mL-', and larval duration, pupation rate, and pupal weight changed considerably with the increase in concentrations. The fecundity, larval livability, larval weight and pupal weight of subsequent generations were reduced as the dose increased over 10 ug mL-1. The hatching rate of egg pods did not differ with that of the controls obviously after treatment in 10-300 ug mL-1. But the larval livability, larval weight and pupal weight were reduced when eggs were exposed to 50 ug mL-1 dose or more. The results indicated that tebufenozide had low resistance risk to the current and subsequent generations of beet armyworm even if tebufenozide had significant effects on the biological characteristics of this insect.

  4. The Impact of Multi-Sensor Data Assimilation on Plant Parameter Retrieval and Yield Estimation for Sugar Beet

    Yield Maps are a basic information source for site-specific farming. For sugar beet they are not available as in-situ measurements. This gap of information can be filled with Earth Observation (EO) data in combination with a plant growth model (PROMET) to improve farming and harvest management. The estimation of yield based on optical satellite imagery and crop growth modelling is more challenging for sugar beet than for other crop types since the plants' roots are harvested. These are not directly visible from EO. In this study, the impact of multi-sensor data assimilation on the yield estimation for sugar beet is evaluated. Yield and plant growth are modelled with PROMET. This multi-physics, raster-based model calculates photosynthesis and crop growth based on the physiological processes in the plant, including the distribution of biomass into the different plant organs (roots, stem, leaves and fruit) at different phenological stages. The crop variable used in the assimilation is the green (photosynthetically active) leaf area, which is derived as spatially heterogeneous input from optical satellite imagery with the radiative transfer model SLC (Soil-Leaf-Canopy). Leaf area index was retrieved from RapidEye, Landsat 8 OLI and Landsat 7 ETM+ data. It could be shown that the used methods are very suitable to derive plant parameters time-series with different sensors. The LAI retrievals from different sensors are quantitatively compared to each other. Results for sugar beet yield estimation are shown for a test-site in Southern Germany. The validation of the yield estimation for the years 2012 to 2014 shows that the approach reproduced the measured yield on field level with high accuracy. Finally, it is demonstrated through comparison of different spatial resolutions that small-scale in-field variety is modelled with adequate results at 20 m raster size, but the results could be improved by recalculating the assimilation at a finer spatial resolution of 5 m.

    The extraction of pectin from sugar beet pulp by citric acid was carried out under different conditions using Box-Behnken design for four independent variables (pH, temperature, time and liquid to solid ratio). The yield of sugar beet pulp pectin ranged from 6.3% to 23.0%, and the content of protein from 1.5% to 4.5%. All independent variables significantly affected the yield, and all variables except liquid to solid ratio significantly affected the protein content. The yield increased as decreasing pH of extracting solution, extending time and advancing temperature, and an opposite relationship of effects between variables and content of protein was obtained. The chemical composition of collected samples was determined. Moreover, from the results of emulsifying properties study, the extracted pectin from sugar beet pulp could prepare steady oil-in-water emulsions. Therefore, it was inferred that the extraction conditions could influence yield and protein content, resulting in different emulsifying property. PMID:26050895

    This study characterized a novel sugar beet (Beta vulgaris L.) pathogen from the Red River Valley in north central USA, which was formally named Fusarium secorum. Molecular phylogenetic analyses of three loci (translation elongation factor1α, calmodulin, mitochondrial small subunit) and phenotypic data strongly supported the inclusion of F. secorum in the Fusarium fujikuroi species complex (FFSC). Phylogenetic analyses identified F. secorum as a sister taxon of F. acutatum and a member of the African subclade of the FFSC. Fusarium secorum produced circinate hyphae sometimes bearing microconidia and abundant corkscrew-shaped hyphae in culture. To assess mycotoxin production potential, 45 typical secondary metabolites were tested in F. secorum rice cultures, but only beauvericin was produced in detectable amounts by each isolate. Results of pathogenicity experiments revealed that F. secorum isolates are able to induce half- and full-leaf yellowing foliar symptoms and vascular necrosis in roots and petioles of sugar beet. Inoculation with F. acutatum did not result in any disease symptoms. The sugar beet disease caused by F. secorum is named Fusarium yellowing decline. Since Fusarium yellowing decline incidence has been increasing in the Red River Valley, disease management options are discussed. PMID:25209635

    Post-harvest colonization of sugar beets accompanied by rot development is a serious problem due to sugar losses and negative impact on processing quality. Studies on the microbial community associated with rot development and factors shaping their structure are missing. Therefore, high-throughput sequencing was applied to describe the influence of environment, plant genotype and storage temperature (8°C and 20°C) on three different communities in stored sugar beets, namely fungi (internal transcribed spacers 1 and 2), Fusarium spp. (elongation factor-1α gene fragment) and oomycetes (internal transcribed spacers 1). The composition of the fungal community changed during storage mostly influenced by the storage temperature followed by a weak environmental effect. Botrytis cinerea was the prevalent species at 8°C whereas members of the fungal genera Fusarium and Penicillium became dominant at 20°C. This shift was independent of the plant genotype. Species richness within the genus Fusarium also increased during storage at both temperatures whereas the oomycetes community did not change. Moreover, oomycetes species were absent after storage at 20°C. The results of the present study clearly show that rot development during sugar beet storage is associated with pathogens well known as causal agents of post-harvest diseases in many other crops.

  9. Production of methane from sugar beet silage without manure addition by a single-stage anaerobic digestion process

    International Nuclear Information System (INIS)

    Single-stage continuous anaerobic conversion of sugar beet silage without manure to methane was investigated in this experimental work, using a laboratory-scale mesophilic anaerobic biogas digester. The sugar beet silage had an extreme low pH of 3.3. The reactor was operated in a hydraulic retention time (HRT) range of between 95 and 15 days, and an organic loading rate (OLR) range of between 0.937 and 6.33 g-1 VS l-1 d-1. The highest specific gas production rate (spec. GPR) of 0.72 l g VS-1 d-1 could be obtained at 25 days of HRT, with an average methane content of about 63%, at a pH of around 6.8. Since sugar beet silage without the leaves is a poor substrate, in terms of the availability of the nutrients and the buffering capacity, external supplementation of nitrogen and buffering agents has to be regularly performed, in order to achieve a stable and an efficient process. Sodium or potassium hydrogen carbonate addition seemed to function best in our case, among the other agents used, to provide adequate buffering capacity and to keep the digester pH stable during the operation. Use of a new harvest (a new charge of substrate) also affected the spec. GPR values significantly

    At least 16 taxa of cicadellids and delphacids were tested by polymerase chain reaction (PCR) for the presence of a phytoplasma in the clover proliferation group, designated 16SrVI. Nucleic acid extracts from individual insects or groups of 5-10 were tested using PCR primers designed from the DNA sequence of 16S-23S rRNA or ribosomal protein genes of the pathogen. The beet leafhopper, Circulifer tenellus (Baker), was most often associated with the phytoplasma, with approximately 16% of the insects testing positive. The phytoplasma was occasionally found associated with Ceratagallia spp. Leafhopper species that were not associated with the phytoplasma included Macrosteles spp., Dikraneura spp., Colladonus montanus (Van Duzee), Circulifer geminatus (Van Duzee), Ballana spp., Amplysellus spp., Paraphlepsius spp., Texananus spp., Balclutha spp., Latalus spp., Erythroneura spp., Exitianus exitiosus (Uhler), and unidentified delphacids. The detected phytoplasma was similar to, or synonymous with, the beet leafhopper-transmitted virescence agent that is associated with the potato purple top disease in the Columbia Basin region of Washington and Oregon. This is in contrast to the phytoplasma associated with potato purple top disease in Mexico that is related to aster yellows (group 16SrI). The association of the group 16SrVI phytoplasma almost exclusively with the beet leafhopper suggests that this insect is the major vector of the phytoplasma in this region. PMID:15889714

  11. Effect of Saline Water on Yield and Nitrogen Acquisition by Sugar Beet (Beta vulgaris L.) Using 15N Technique

    International Nuclear Information System (INIS)

    Sugar beet growth response to the interactive effects of salinity and N-fertilization was investigated using 15N tracer technique under greenhouse condition. Data showed that dry matter yield of sugar beet shoots and roots were frequently affected by N and water regime. Total N uptake by leaves was increased under almost water salinity treatments in spite of increasing salinity levels. It appears that in case of WI, NII the N-uptake by roots was significantly decreased along with raising salinity levels from 4 to 8 dS/m. The portions of N derived from fertilizer (whole plant) showed that the trend was affected by salinity level of irrigation water, and fertilization treatments. The highest amount of N derived from fertilizer was obtained with the 4 dS/m level under NII with the two water regimes. The efficient use of fertilizer-N was slightly but positively affected by raising salinity levels of irrigation water. Sugar percent was increased with increasing salinity levels of irrigation water under both NI and NII treatments, but it was higher in case of NI than NII under different salinity levels. Generally, Irrigation with saline water in combination with water regime of 75-80% of field capacity and splitting nitrogen technique are better for enhancement of sugar beet production grown under such adverse conditions

    Sugar beet. one of two principal sugar crops in Egypt. is subjected to infestation with various insect pests. which cause considerable damage to the plants. Profenofos is an important insecticide recommended by ministry of agriculture for controlling pests on sugar beet plants. The residues of this insecticide on and in both the vegetative and root parts were identified using 14C-labelled compound which has been synthesized for this purpose. ()-(2-chlorophenyl) - ()-ethyl-S-propyl phosphorothioate. ()-ethyl-S-propyl phosphorothioate. ()-4-(bromo 2 chlorophenyl) monoethyl phosphate. ())-transformation products. The phenolic compounds were found in the free and conjugated forms. The results shows that the vegetative parts contained high levels of 14C-residues and are not recommended to use animal feed after treatment with this insecticide. On the other hand and depending upon the present investigation. it could be concluded that the root parts could safety be used for extracting sugar. Moreover. processing of beet extract showed that a negligible percent of 14C -residues is present in the sugar crystals

    Impact of insect pests makes a significant limitation of the sugar beet crop yield. Integration of cry-genes of Bacillus thuringiensis into plant genome is one of the promising strategies to ensure plant resistance. The aim of this work was to obtain sugar beet lines (based on the MM 1/2 line) transformed with cry2A and cry1Cgenes. We have optimized transformation protocol and direct plant let regeneration protocol from leaf explants using 1 mg/l benzylaminopurine as well as 0,25 mg/l benzylaminopurine and 0,1 mg/l indole-butyric acid. Consequently, transgenic sugar beet lines transformed with vector constructs pRD400-cry1C and pRD400-cry2A have been obtained. PCR analysis revealed integration of cry2A and cry1C into genome of transgenic lines and expression of these genes in leaf tissues was shown by reverse transcription PCR. PMID:24818505

    Full Text Available Two-year sugar beet trials were set up on two localities: Đakovo (Stagnic Luvisol and Osijek (Dystric Cambisol. The soils showed acid environment respond (pHKCL 4.9 – 5.4 and low humus contents (1.3 – 1.6%. The trial aimed to investigate use possibility of carbocalc (CC – pressed saturated silt (30% CaO and 40 t/ha stable manure in amendment of already determined unfavourable soil properties, increasing number of soil benefit microorganisms, as well as influence of obtained changes in weed control, sugar beet yield and quality. The weeds were controlled once with full-dose herbicides, repeated low-doses and by hoeing. Weed types, their number and weight were determined on 1 m2 in the July second decade. The investigation results show that carbocalc application (CC brought about increased pHKCL to 7.12 – 7.18 whereas stable manure one resulted in humus increased to 1.73 – 1.95%. It was resulted in increasing of number of bacteria, actinomycetes as well as aerobic asimbiotic nitrogen fixing bacteria – Azotobacter chroococcum. Weed prevailed were as follows : Ambrosia artemisiifolia L., Polygonum persicarie L., Amaranthus retroflexus L. and Echinochloa crus galli L. Total number of weeds without protection application was on the average 83.2 weeds/m2 and weight 4012 g. Hoeing resulted in decreased number of weeds to 2.9 weeds/m2 – weight 111 g, repeated herbicides application to 6.3 weeds/m2 – weight 294 g whereas the worst results , at weeds control, were obtained by the once herbicides control variant (9.1 weed/m2 i.e. 534 g. Low- dose herbicide application variants resulted in higher root yield (48.5 t/ha compared to the once application (45.1 t/ha. However, hoeing brought about the highest root (50.8 t/ha and sugar yield (6.2 t/ha. Root yield was very significantly increased and sugar yield significantly by carbocalc (CC application compared to the control.

    The nuclear rDNA units of species belonging to the genus Beta were characterized using heterologous probes of flax (entire unit and 25S) and sunflower (6.1-kb Eco fragment containing the 18S, the entire intergenic spacer (IGS) and a small piece of the 25S). The physical maps of one species from each section of the genus was constructed by localization of the EcoRI, BamHI, HindIII, KpnI and SacI restriction sites. For each species a single individual was used to obtain total DNA. The major unit length is 11 kb, but variant length units at 10.4, 10.7 and 11.3 kb were found as minor forms. However, some individuals carried the 10.4-kb or the 10.7-kb variant length unit as the major form. For the variant length units of one species the restriction sites were conserved, so that the variation in length occurred in the IGS. The EcoRI fragment corresponding to the intergenic spacer appeared to be the best indicator of variation. The variable sequence in the IGS sometimes generated new restriction sites for the Corollinae and mainly, did so, for the Vulgares relative to the Procumbentes. The variable sites were able, to differentiate the three sections and species within the sections. Corollinae species belong to two different groups according to the absence or the presence of the BamHI (B4) site. The Vulgares species contain several unit types. We proposed that all the unit types derived from a unique unit, V-11-2.3, by unequal crossing-overs or conversion. We also supposed a homogenization mechanism because we found individuals homogeneous for every unit type. Among the cultivated beets, all the root beets contain only one rDNA unit type, V-11-2.9. Thus, we supposed that the common unit type of cultivated beets either brings a physiological advantage or is strictly linked to a favorable allele. It is likely that the rDNA unit of B. maritima were eliminated from sugar beet by the breeding process since they were not recovered. Whatever the process, we deduced that all the

    Full Text Available Summary. Recent studies have identified that hydrophobic phenolic phytochemicals and hydrophilic Amadori compounds have potential for type 2 diabetes management via inhibition of carbohydrate hydrolysis enzymes. Here, we determined the phenolic content, α-glucosidase inhibitory activity, and pancreatic α-amylase inhibitory activity of water extracts of roasted and unroasted coffee beans and dried sugar beet leaves. Sugar beet leaves appeared to have the lowest total phenolic content while unroasted and roasted coffee beans had similar phenolic contents (1.49 and 1.40 mg/mL GAE DW respectively. All tested samples resulted to a dose-dependent α-glucosidase inhibitory activity. Sugar beet leaves had significant inhibitory activity (78% at the highest dose and after C18 extraction this activity appeared to be both hydrophilic and hydrophobic compound dependent.  Roasted coffee beans had significantly higher α-glucosidase inhibitory activity when compared to green coffee beans at all tested doses. Roasted coffee beans were subjected to C18 extraction and the α-glucosidase inhibitory activity was evaluated and determined to be solely hydrophobic compound dependent. When the α-amylase inhibitory activity was evaluated, no inhibition was observed with all tested samples. Our findings indicate that the observed bioactivities in coffee beans is hydrophobic compound dependent, while in sugar beet leaves the observed effect is possibly due to the synergistic effect of both hydrophobic and hydrophilic fractions. This is the first report on the carbohydrate hydrolyzing enzyme inhibition of roasted coffee beans and sugar beet leaves.Industrial Relevance. Sugar beets are widely cultivated in Europe and Northern Asia for the production of table sugar. After the harvesting of sugar beets large quantities of sugar beet leaves remain on the field and are either left to become fertilizer or appropriately disposed.

    In order to establish a supply system for energy resource coupled with the environment,the production technology of sugar beets was explored as a biological energy source. The low-humic andosol as the experimental soil,the panting method was direct planting,and cultivation technique was minimum tillage direct planting method. The control was conventional tillage transplant and no tillage direct planting. The results demonstrated that data revealed that the energy cost of no tillage and a direct planting method was 105 GJ/hm2on average for two years,while that of the conventional tillage method was 112 GJ/hm2per year. The ratio of output to input showed that the direct planting with no tillage was more efficient( 3. 61) than the conventional tillage( 3. 01). Moreover,the emission of CO2into the atmosphere with no tillage and the direct planting was 71% of the conventional tillage planting technique. Therefore,direct planting without tillage reduces the impact on the environment.

    Full Text Available Intake of fruits and vegetables rich in antioxidants is suggested to reduce the incidence of cancer and coronary heart disease in humans. Exceptional antioxidant activity of beet root extracts has been reported. Likewise in animal models, e.g., extracts of red beetroot Beta vulgaris var. rubra revealed significant tumor inhibitory effects. Red beetroot concentrate is universally permitted as a food ingredient. In this study, effects of a commercially available beetroot juice on freshly isolated human peripheral blood mononuclear cells stimulated with the mitogens phytohaemagglutinin and concanavalin A were investigated in vitro. Tryptophan degradation and neopterin formation were monitored in culture supernatants to determine effects of test substances on immunobiochemical pathways which both are induced by the pro-inflammatory cytokine interferon-γ. Compared to unstimulated cells, the mitogens induced significant formation of neopterin and degradation of tryptophan which is reflected by increasing concentrations of kynurenine together with diminished tryptophan levels in supernatants. Addition of beetroot extracts significantly suppressed these mitogen-induced changes, e.g. the rate of neopterin production as well as tryptophan degradation was dose-dependently suppressed. Our data show that beetroot extract is able to counteract pro-inflammatory cascades in peripheral blood mononuclear cells. Because inflammation is strongly involved in the development and progression of several clinical conditions including coronary heart disease and cancer, beneficial effect of beetroot extract may relate to this anti-inflammatory capacity.

    Full Text Available In sugar industry, there is a problem of the presence of undesirable macromolecules such as pectins in sugar beet juice. Separation of these compounds is done mostly by CaO. Calcium may cause undesirable process of alkalization of soil in the near environment of the sugar factory. The theoretical basis of new juice purificatin method based on the application of Al2(SO43, CaSO4 and their mixtures are presented. Two model solutions of pectin (0.1 % w/w are investigated using a method of measuring zeta potential. Pure salts Al2(SO43 and CaSO4, showed better binding properties with the pectin than mixtures. Amount of all studied pure salts and mixtures of Al3+ and Ca2+ ions were significantly less (142 - 710 mg/gpectin than the average amount of CaO used in classical process (about 9 g/gpectin. Mechanism of discharge of pectin macromolecules in the presence of mixtures of these ions using a model of double electric layer are suggested.

    Full Text Available The current study was carried out to analyse three sugar beet genotypes regarding to the economic yield and the potential to produce bioethanol, under the influence of furrow irrigation regime in specific conditions of Transylvanian Plain, North-West Romania. The research factors, genotype (‘Leila’, ‘Clementina’ and ‘Libero’ and irrigation regime were studied within a polyfactorial experimental design. The results obtained indicated that in specific climatic conditions of Transylvanian Plain, ‘Libero’ genotype had a great performance and produced the highest yields. The average production of ‘Libero’ genotype was superior than ‘Clementina’ and ‘Leila’ varieties, both in irrigated and non-irrigated conditions, as it follows: 38.98 t ha–1, respectively, 52.72 t ha–1 in the first year of research; 47.63 t ha–1, respectively, 59.73 t ha–1 (in the second year; 2014-60.87 t ha–1, respectively, 74.43 t ha–1 (in the third year. Moreover, the production increased with 11.5% under irrigated conditions for all the studied genotypes. The results also revealed the positive influence of the irrigation regime on the qualitative parameters of the bioethanol (ethanol, higher saturated monoalcohols, methanol, water, inorganic chloride, cooper, phosphorous, sulphur etc. indicating that the obtained bioethanol might be a viable alternative for fossil fuels.

    Full Text Available Three polyphenols were isolated and purified from sugar beet molasses by ultrasonic-aid extraction and various chromatographic techniques, and their structures were elucidated by spectral analysis. Cytotoxicity and the molecular mechanism were measured by methyl thiazolyl tetrazolium (MTT assay, flow cytometry, caspase-3 activity assay and Western blot assay. The results showed that gallic acid, cyanidin-3-O-glucoside chloride and epicatechin have cytotoxicity to the human colon, hepatocellular and breast cancer cells. Cyanidin-3-O-glucoside chloride showed its cytotoxicity against various tumor cell lines, particularly against colon cancer Caco-2 cells with half maximal inhibitory concentration (IC50 value of 23.21 ± 0.14 μg/mL in vitro. Cyanidin-3-O-glucoside chloride may be a potential candidate for the treatment of colon cancer. In the mechanism study, cyanidin-3-O-glucoside chloride increased the ratio of cell cycle at G0/G1 phase and reduced cyclin D1 expression on Caco-2 cells. Cyanidin-3-O-glucoside chloride decreased mutant p21 expression, and increased the ratio of Bax/Bcl-2 and the activation of caspase-3 to induce apoptosis.

    Eight kestose isomers were isolated from sugar beet molasses by carbon-Celite column chromatography and HPLC. GC-FID and GC-MS analyses of methyl derivatives, MALD-TOF-MS measurements and NMR spectra were used to confirm the structural characteristics of the isomers. The (1)H and (13)C NMR signals of each isomer saccharide were assigned using COSY, E-HSQC, HSQC-TOCSY, HMBC and H2BC techniques. These kestose isomers were identified as α-D-fructofuranosyl-(2- > 2)-α-D-glucopyranosyl-(1 2)-β-D-fructofuranoside, α-D-fructofuranosyl-(2- > 3)-β-D-fructofuranosyl-(2 1)-α-D-glucopyranoside, α-D-fructofuranosyl-(2- > 4)-β-D-fructofuranosyl-(2 1)-α-D-glucopyranoside, β-D-fructofuranosyl-(2- > 4)-β-D-fructofuranosyl-(2 1)-α-D-glucopyranoside, β-D-fructofuranosyl-(2- > 3)-α-D-glucopyranosyl-(1 2)-β-D-fructofuranoside, α-D-fructofuranosyl-(2- > 1)-β-D-fructofuranosyl-(2 1)-α-D-glucopyranoside, α-D-fructofuranosyl-(2- > 6)-α-D-glucopyranosyl-(1 2)-β-D-fructofuranoside, and α-D-fructofuranosyl-(2- > 6)-β-D-fructofuranosyl-(2 1)-α-D-glucopyranoside.

    The second most abundant bacterium on the root surface of young sugar beet plants was identified as a Phyllobacterium sp. (Rhizobiaceae) based on a comparison of the results of 39 conventional identification tests, 167 API tests, 30 antibiotic susceptibility tests, and sodium dodecyl sulfate-polyacrylamide gel electrophoretic fingerprints of total cellular proteins with type strains of Phyllobacterium myrsinacearum and Phyllobacterium rubiacearum. It was found on 198 of 1,100 investigated plants between the 2nd and 10th leaf stage on three different fields in Belgium and one field in Spain. Densities ranged from 2 x 10 to 2 x 10 CFU/g of root. Five isolates exerted a broad-spectrum in vitro antifungal activity. DNA-DNA hybridizations showed that Phyllobacterium sp. does not contain DNA sequences that are homologous with the attachment genes chvA, chvB, the transferred-DNA (T-DNA) hormone genes iaaH and ipt from Agrobacterium tumefaciens, iaaM from A. tumefaciens and Pseudomonas savastanoi, or the nitrogenase genes nifHDK from Klebsiella pneumoniae. Phyllobacterium sp. produces indolylacetic acid in in vitro cultures and induces auxinlike effects when cocultivated with callus tissue of tobacco. When Phyllobacterium sp. was transformed with a Ti plasmid derivative, it gained the capacity to induce tumors on Kalanchoe daigremontiana. The potential role of Phyllobacterium sp. in this newly recognized niche is discussed. PMID:16348158

    In this study, sugar beets (Beta vulgaris L.) were grown at different K(+)/Na(+) concentrations: mmol/L, 3/0 (control); 0.03/2.97 (K-Na replacement group; T(rep)); 0.03/0 (K deficiency group; T(def)) in order to investigate the effects of K(+) deficiency and replacement of K(+) by Na(+) on plant proteomics, and to explore the physiological processes influenced by Na(+) to compensate for a lack of K(+). After 22 days, fresh and dry weight as well as the Na(+) and K(+) concentration were measured and changes in proteomics were tested by 2D gel electrophoresis. Interestingly, Na(+) showed stimulation in growth of seedlings and hindrance of K(+) assimilation in T(rep). Significant changes were also observed in 27 protein spots among the treatments. These are proteins involved in photosynthesis, cellular respiration, protein folding and degradation, stress and defense, other metabolisms, transcription related, and protein synthesis. A wide range of physiological processes, including light reaction, CO2 assimilation, glycolysis, and tricaboxylic acid cycle, was impaired owing to K(+) starvation. Compensating for the effect of K(+) starvation, an increase in photosynthesis was also observed in T(rep). However, we also found a limitation of cellular respiration by Na(+). Na(+) is therefore in some ways able to recover damage due to K deficiency at protein level, but cannot functionally replace K as an essential nutrient. PMID:26860314

    This study was conducted to investigate the prebiotic effects of linear arabino-oligosaccharides (LAOS) and debranched (linear) sugar beet arabinan (LAR) for the development of new prebiotics. LAOS were prepared from LAR by enzymatic hydrolysis with endo-arabinanase from Bacillus licheniformis, followed by removal of the arabinose fraction by incubation with resting cells of Leuconostoc mesenteroides. The resulting LAOS contained DP2 (28.7%), DP3 (49.9%), DP4 (20.1%), and DP5 (1.16%). A standardized digestibility test showed that LAOS and LAR were not digestible. Individual cultures of 24 strains of gastrointestinal bacteria showed that LAOS and LAR stimulated growth of Lactobacillus brevis, Bifidobacterium longum, and Bacteroides fragilis. In vitro batch fermentation using human fecal samples showed that LAOS had higher bifidogenic properties than LAR; LAOS increased the population of bifidobacteria which produced short-chain fatty acids (SCFAs). LAOS was fermented slowly compared to fructo-oligosaccharides and this may permit SCFA production in the distal colon. This study demonstrates that LAOS prepared from LAR are promising dietary substrates for improvement of human intestinal health. PMID:26256159

  8. Electric double layer and electrokinetic potential of pectic macromolecules in sugar beet

    Directory of Open Access Journals (Sweden)

    Kuljanin Tatjana A.

    2008-01-01

    Full Text Available Electrokinetic potential is an important property of colloidal particles and, regarding the fact that it is a well defined and easily measurable property, it is considered to be a permanent characteristic of a particular colloidal system. In fact, it is a measure of electrokinetic charge that surrounds the colloidal particle in a solution and is in direct proportion with the mobility of particles in an electric field. Gouy-Chapman-Stern-Graham's model of electric double layer was adopted and it was proven experimentally that the addition of Cu++ ions to sugar beet pectin caused a reduction in the negative electrokinetic potential proportional to the increase of Cu++ concentration. Higher Cu++ concentrations increased the proportion of cation specific adsorption (Cu++ and H+ with regard to electrostatic Coulombic forces. Consequently, there is a shift in the shear plane between the fixed and diffuse layers directed towards the diffuse layer, i.e. towards its compression and decrease in the electrokinetic potential or even charge inversion of pectin macromolecules.

    Pesticide transport from seed dressings toward subsurface tile drains is still poorly understood. We monitored the neonicotinoid insecticides imidacloprid and thiamethoxam from sugar beet seed dressings in flow-proportional drainage water samples, together with spray applications of bromide and the herbicide S-metolachlor in spring and the fungicides epoxiconazole and kresoxim-methyl in summer. Event-driven, high first concentration maxima up to 2830 and 1290 ng/L for thiamethoxam and imidacloprid, respectively, were followed by an extended period of tailing and suggested preferential flow. Nevertheless, mass recoveries declined in agreement with the degradation and sorption properties collated in the groundwater ubiquity score, following the order bromide (4.9%), thiamethoxam (1.2%), imidacloprid (0.48%), kresoxim-methyl acid (0.17%), S-metolachlor (0.032%), epoxiconazole (0.013%), and kresoxim-methyl (0.003%), and indicated increased leaching from seed dressings compared to spray applications. Measured concentrations and mass recoveries indicate that subsurface tile drains contribute to surface water contamination with neonicotinoids from seed dressings. PMID:27529118

    Full Text Available Distillery wastewaters have a great pollution potential, and pollution caused by them is one of the most critical environmental issues. This study is concerned with the coagulation efficiency of a new, environmental friendly, natural coagulant extracted from common bean seeds in the primary treatment of distillery wastewater in the bioethanol production from sugar beet juice. Active coagulation components were extracted from ground seeds of common bean with 0.5 mol/L NaCl. The obtained raw extract was used as a coagulant. The coagulation efficiency was measured by jar test at different pH values of wastewater, and a decrease in organic matter content was determined. The experiments confirmed that natural coagulant from common bean could be successfully used for the treatment of extraction juice distillery wastewater. The highest coagulation efficiencies were achieved at the pH 5.2 with a coagulant dose of 30 mL/L, and at the pH 8.5 with a coagulant dose of 5 mL/L, and they were 64.71% and 68.75% respectively. These encouraging results indicate that natural coagulant from common bean seeds is a potential alternative to conventional chemical coagulant/flocculant agents for treatment of wastewaters.[Projekat Ministarstva nauke Republike Srbije, br.

    Full Text Available In this paper, the authors present the obtained results regarding the flight dynamics of some Lepidoptera species in sugar beet crops in Transylvania (the central part of Romania. In order to limit the appearance of mentioned pests to the economic threshold, Trichogramma spp. were obtained in laboratory conditions at ARDS Turda and SBRDS Brasov. The experiments were conducted in production areas on 0,5 ha minimum for each variant. The variants included four Trichogramma species: T. dendrolimi, T. evanescens, T. maidis, T. buesi that were manually released three times: the first release, 10.000 individuals/ha, the second, 120.000 individuals/ha and the third, 150.000 individuals/ha. The first release was performed at the beginning of the Lepidoptera flight, the second at the maximum flight and the third 5 days after the second. The efficiency of T. maidis was between 75-90%, of T. evanescens, it was between 73-88%, of T. dendrolimi, it was between 85-92% and of T. buesi 79-82%. Among the Trichogramma species utilized, T. dendrolimi and T. evanescens were very efficient in the reduction of mentioned pests. Root production was significantly higher compared to the untreated variant, 4,0-4,7 t/ha more were recorded after the application of biological treatments with T. evanescens and T. dendrolimi.

    Glycine betaine (GB) is an important osmoprotectant and synthesized by two-step oxidation of choline. Choline monooxygenase (CMO) catalyzes the first step of the pathway and is believed to be a rate limiting step for GB synthesis. Recent studies have shown the importance of choline-precursor supply for GB synthesis. In order to investigate the role of CMO for GB accumulation in sugar beet (Beta vulgaris), transgenic plants carrying the antisense BvCMO gene were developed. The antisense BvCMO plants showed the decreased activity of GB synthesis from choline compared to wild-type (WT) plants which is well related to the suppressed level of BvCMO protein. However, GB contents were similar between transgenic and WT plants with the exception of young leaves and storage roots. Transgenic plants showed enhanced susceptibility to salt stress than WT plants. These results suggest the importance of choline-precursor-supply for GB accumulation, and young leaves and storage root are sensitive sites for GB accumulation. PMID:26302482

  13. Genetic variation among the male sterile cytoplasms induced by gamma irradiation in sugar beets

    International Nuclear Information System (INIS)

    In sugar beets, cytoplasmic male sterility was induced artificially by radiation treatment. In the present study, four kinds of male sterile strain made from the strain H-2002 with normal cytoplasms were used, and the mode of inheritance of the sterility maintained by these strains was confirmed. Also the hereditary mechanism of pollen fructification recovery was studied, and the newly induced heterotypic property of sterile cytoplasms was examined in comparison with naturally found sterile strains. In each of four produced strains, the male sterility was inherited down to M4 lines stably through mother plants, and it was presumed that the sterility was caused by highly stable cytoplasmic mutation. In each strain, two pairs of nuclear genes took part in the recovery of pollen fructification, but the mode of action of two genes was different. As the result of mating for verification with O type strain to S cytoplasm strain, it seemed that at least the function as O type was not shown to three strains of γ-60, γ-114 and γ-165, and in the sterile cytoplasms of these three strains, the action of fructification recovery genes different from X and Z arose. It was presumed that the genes of X locus did not take effect in these induced cytoplasms. The possibility that at least four kinds of male sterile cytoplasms different from S were induced from normal cytoplasms by artificial mutation was proved indirectly. (Kako, I.)

    Results of sugar beet pulp silage (SBPS) and vinasse (mixed in weight ratios of 3:1, 1:1 and 1:3, respectively) co-fermentation, obtained in this study, provide evidence that addition of too high amount of vinasse into the SBPS decreases biogas yields. The highest biogas productivity (598.1mL/g VS) was achieved at the SBPS-vinasse ratio of 3:1 (w/w). Biogas yields from separately fermented SBPS and vinasse were by 13% and 28.6% lower, respectively. It was found that enzymatic pretreatment of SBPS before methane fermentation that caused partial degradation of component polysaccharides, considerably increased biogas production. The highest biogas yield (765.5mL/g VS) was obtained from enzymatic digests of SBPS-vinasse (3:1) blend (27.9% more than from fermentation of the counterpart blend, which was not treated with enzymes). The simulation of potential biogas production from all the aforementioned mixtures using the Gompertz equation showed fair fit to the experimental results. PMID:25618496

  15. Isolation and characterization of protoplasts and vacuoles from sugar beet leaf mesophyll

    International Nuclear Information System (INIS)

    The present paper describes methods for isolation of protoplasts and vacuoles from sugar beet (Beta vulgaris L.) leaf mesophyll. Protoplasts were isolated by the enzymatic method in two stages. The yield of protoplasts in the crude suspension attained 3-10 units from 1g of fresh tissue mass. Two methods of purifying the crude protoplast suspension are compared in the paper, the indicated methods employing gradients of Percoll (method 1) and Ficoll (method 2). The final yield comprised 4.5-9.0-10.5 protoplasts from 1g of fresh tissue mass after purification method 1 and 6.0-10.5-1.2-10 protoplasts after method 2. The photosynthesis rate in such protoplasts under optimal conditions comprised 75-100 μmoles of CO2h per mg of chlorophyll as compared with 100-130 μmoles in leaf blade disks. The two methods were used to obtain vacuoles, method 1 involving osmotic lysis of protoplasts (the yield constituting 6-15% of vacuoles of the protoplasts taken) and method 2 consisting of ultracentrifugation in a Ficoll gradient (giving a yield of 25-45%). As was monitored microscopically and from the absence of activity of extravacuolar enzymes (NADH-cytochrome-c reductase and cytochrome-c oxidase), vacuoles free of foreign impurities were obtained in both cases. The time needed to obtain protoplasts from leaf tissue comprised 2-3 h, whereas 1.5-2 h was needed to obtain vacuoles from protoplasts

  16. Evidence for the presence of a sucrose carrier in immature sugar beet tap roots

    International Nuclear Information System (INIS)

    The objectives of this work were to determine the path of phloem unloading and if a sucrose carrier was present in young sugar beet (Beta vulgaris L.) taproots. The approach was to exploit the characteristics of the sucrose analog, 1'-fluorosucrose (F-sucrose) which is a poor substrate for acid invertase but is a substrate for sucrose synthase. Ten millimolar each of [3H] sucrose and [14C]F-sucrose were applied in a 1:1 ratio to an abraded region of an attached leaf for 6 hours. [14C]F-sucrose was translocated and accumulated in the roots at a higher rate than [3H]sucrose. This was due to [3H]sucrose hydrolysis along the translocation path. Presence of [3H]hexose and [14C]F-sucrose in the root apoplast suggested apoplastic sucrose unloading with its subsequent hydrolysis. Labeled F-sucrose uptake by root tissue discs exhibited biphasic kinetics and was inhibited by unlabeled sucrose, indicating that immature roots have the ability for carrier-mediated sucrose transport from the apoplast. Collectively, in vivo and in vitro data indicate that despite sucrose hydrolysis by the wall-bound invertase, sucrose hydrolysis is not entirely essential for sugar accumulation in this tissue

    Sugar beet pulp (SBP) has been investigated as a promising feedstock for ABE fermentation by Clostridium beijerinckii. Although lignin content in SBP is low, a pretreatment is needed to enhance enzymatic hydrolysis and fermentation yields. Autohydrolysis at pH 4 has been selected as the best pretreatment for SBP in terms of sugars release and acetone and butanol production. The best overall sugars release yields from raw SBP ranged from 66.2% to 70.6% for this pretreatment. The highest ABE yield achieved was 0.4g/g (5.1g/L of acetone and 6.6g/L butanol) and 143.2g ABE/kg SBP (62.3g acetone and 80.9g butanol) were obtained when pretreated SBP was enzymatically hydrolyzed at 7.5% (w/w) solid loading. Higher solid loadings (10%) offered higher acetone and butanol titers (5.8g/L of acetone and 7.8g/L butanol). All the experiments were carried out under not-controlling pH conditions reaching about 5.3 in the final samples. PMID:25965949

  18. Yield response of cotton, maize, soybean, sugar beet, sunflower and wheat to deficit irrigation

    International Nuclear Information System (INIS)

    Results of several field experiments on deficit irrigation programmes in Turkey are discussed. Deficit irrigation of sugar beet with water stress imposed (i e.,irrigation omitted)during ripening,stage saved nearly 22 % water, yet with no significant yield decrease. An experiment, conducted in Turkey Region, the European part of Turkey,and aimed at studying water production functions of sunflower(i e,yield vs water consumption), revealed that water stress imposed at either head forming or seed filling stags influence yield the least , and 40 % savings of irrigation water supply , compared with traditional practices in the region, can be achieved without significant yield reduction. Water stress imposed at vegetative and flowering stages of maize hindered the yield most significantly. The results showed that deficit irrigation can be a feasible option under limited supply of irrigation if stress occurs during yield formation stage. A four year field experiments aiming at developing deficit irrigation strategies for soybean showed that soybean was at the most sensitive to water stress during flowering and pod filling stages, and irrigation during these stages would ensure high yields. Results of experiments on cotton showed that irrigations omitted during yield formation stage did not significantly hinder the yield. Similarly wheat give good yield response if irrigated at booting,heading and milking stages, depending on w heather conditions. In areas where rainfall at planting is limited, supplementary irrigation during this period can ensure good establishment of wheat crop. 1 tab; 9 figs; 59 refs (Author)

  19. Structure and Function of the Ribosomal Frameshifting Pseudoknot RNA from Beet Western Yellow Virus

    Many viruses reprogram ribosomes to produce two different proteins from two different reading frames. So-called -1 frameshifting often involves pairwise alignment of two adjacent tRNAs at a 'slippery' sequence in the ribosomal A and P sites such that an overlapping codon is shifted upstream by one base relative to the zero frame. In the majority of cases, an RNA pseudoknot located downstream stimulates this type of frameshift. Crystal structures of the frameshifting RNA pseudoknot from Beet Western Yellow Virus (BWYV) have provided a detailed picture of the tertiary interactions stabilizing this folding motif, including a minor-groove triplex and quadruple-base interactions. The structure determined at atomic resolution revealed the locations of several magnesium ions and provided insights into the role of structured water stabilizing the RNA. Systematic in vitro and in vivo mutational analyses based on the structural results revealed specific tertiary interactions and regions in the pseudoknot that drastically change frameshifting efficiency. Here, we summarize recent advances in our understanding of pseudoknot-mediated ribosomal frameshifting on the basis of the insights gained from structural and functional studies of the RNA pseudoknot from BWYV.

    DNA methylation is an essential epigenetic feature for the regulation and maintenance of heterochromatin. Satellite DNA is a repetitive sequence component that often occurs in large arrays in heterochromatin of subtelomeric, intercalary and centromeric regions. Knowledge about the methylation status of satellite DNA is important for understanding the role of repetitive DNA in heterochromatization. In this study, we investigated the cytosine methylation of the ancient satellite family pEV in the wild beet Beta procumbens. The pEV satellite is widespread in species-specific pEV subfamilies in the genus Beta and most likely originated before the radiation of the Betoideae and Chenopodioideae. In B. procumbens, the pEV subfamily occurs abundantly and spans intercalary and centromeric regions. To uncover its cytosine methylation, we performed chromosome-wide immunostaining and bisulfite sequencing of pEV satellite repeats. We found that CG and CHG sites are highly methylated while CHH sites show only low levels of methylation. As a consequence of the low frequency of CG and CHG sites and the preferential occurrence of most cytosines in the CHH motif in pEV monomers, this satellite family displays only low levels of total cytosine methylation.

    2015-06-01

    Full Text Available Evaluation of the quality of 15 cultivars of red beet has been made during four successive vegetative seasons. The study involved cultivars ‘Astar F1’, ‘Boro F1’, ‘Ceryl’, ‘Chrobry’, ‘Czerwona Kula’, ‘Egipski’, ‘Karmazyn’, ‘Nabab F1’, ‘Nochowski’, ‘Opolski’, ‘Pablo F1’, ‘Patryk’, ‘Regulski Cylinder’, ‘Okrągły Regulski’ and ‘Rywal’. The mass, diameter of roots, antioxidant activity, the content of dry mass, soluble sugars, betanin and vulgaxanthin in roots were evaluated. The study indicated ‘Chrobry’ as the cultivar of the most favorable quality features. It was characterized by high antioxidant activity, high content of dry mass, soluble sugars and betalain pigments. Among cultivars of cylindrical shaped roots, content of soluble sugars and antiradical activity was the highest in ‘Regulski Cylinder’ roots.

  2. Modes of nitrogen action within the soil-plant system after 15N-nitrogen application to irrigated and non-irrigated sugar beet and late effect on spring barley

    International Nuclear Information System (INIS)

    A long-term trial at a dry site with low groundwater table was used to study differentiated 15N mineral nitrogen applications to sugar beet for the effect on plant (primarily sugar beet) and soil over a period of two years (succeeding crop:spring barley.) Other test factors were manuring and sprinkler irrigation. The high effect of irrigation was clearly reflected by beet body yields and nitrogen uptake by the plants. Sugar beet and barley absorbed 52% and 72% of the nitrogen applied without irrigation and with irrigation, respectively. Apart from the high mineral nitrogen uptake, the soil supplied about 70% of the total nitrogen uptake by the beet. This figure includes also manure N and additional N sources. Irrigation stimulated the uptake of mineral and soil nitrogen by the plants. After two years 33% (non-irrigated) and 24% (irrigated) of the nitrogen applied were still available at a depth of 0 to 60 cm. (author)

    The effect of time and pressure on the selective extraction of sugar beet pectin using steam pre-treatment on unprocessed Sugar Beet Pulp was evaluated using a design of experiments approach. This process gave the highest solubilisation of pectin oligomers at a relatively low pressure and longer time (5Bar, 24min), whilst leaving the majority of the cellulose fraction intact. This method of steam pre-treatment fits into the concept of a sugar beet biorefinery as it valorises an existing waste stream without requiring any further physical processing such as milling or dilution with water. The residual cellulose fraction was enriched in cellulose and could be effectively fermented into ethanol by yeast after enzymatic digestion, producing 0.48g ethanol per gram of glucose.

  4. Belowground plant development measured with magnetic resonance imaging (MRI: exploiting the potential for non-invasive trait quantification using sugar beet as a proxy

    Full Text Available Both structural and functional properties of belowground plant organs are critical for the development and yield of plants but, compared to the shoot, much more difficult to observe due to soil opacity. Many processes concerning the belowground plant performance are not fully understood, in particular spatial and temporal dynamics and their interrelation with environmental factors. We used Magnetic Resonance Imaging (MRI as a noninvasive method to evaluate which traits can be measured when a complex plant organ is monitored in-vivo while growing in the soil. We chose sugar beet (Beta vulgaris ssp. vulgaris as a model system. The beet consists mainly of root tissues, is rather complex regarding tissue structure and responses to environmental factors, and thereby a good object to test the applicability of MRI for 3D phenotyping approaches. Over a time period of up to 3 months, traits such as beet morphology or anatomy were followed in the soil and the effect of differently sized pots on beet fresh weight calculated from MRI data was studied. There was a clear positive correlation between the pot size and the increase in fresh weight of a sugar beet over time. Since knowledge of the development of internal beet structures with several concentric cambia, vascular and parenchyma rings is still limited, we consecutively acquired 3D volumetric images on individual plants using the MRI contrast parameter T2 to map the development of rings at the tissue level. This demonstrates that MRI provides versatile protocols to non-invasively measure plant traits in the soil. It opens new avenues to investigate belowground plant performance under adverse environmental conditions such as drought, nutrient shortage or soil compaction to seek for traits of belowground organs making plants more resilient to stress.

  5. Over-expression of the Hybrid Aspen Homeobox PttKN1 Gene in Red Leaf Beet Induced Altered Coloration of Leaves

    Full Text Available PttKN1 (Populus tremula × tremuloides KNOTTED1 gene belongs to the KNOXI gene family. It plays an important role in plant development, typically in meristem initiation, maintenance and organogenesis, and potentially in plant coloration. To investigate the gene functions further, it was introduced into red leaf beet by the floral dip method mediated via Agrobacterium tumefaciens. The transformants demonstrated typical phenotypes as with other PttKN1 transformants. These alterations were very different from the morphology of the wild type. Among them, morphological modification of changed color throughout the entire plant from claret of wild type to yellowish green was the highlight in those transgenic PttKN1-beet plants. The result of spraying selection showed that the PttKN1-beet plants had kanamycin resistance. PCR assay of the 35S-Promoter, NPTII and PttKN1 gene, PCR-Southern analysis of the NPTII and PttKN1 gene showed that the foreign PttKN1 gene had successfully integrated into the genome of beet plant. Furthermore, the results of RT-PCR analysis showed that the gene was ectopic expressed in transgenic plants. These data suggested that there is a correlation between the ectopic expression of PttKN1 gene and morphological alterations of beet plants. Pigment content assay showed that betaxanthins concentrations shared little difference between wild type and transgenic lines, while betacyanins content in transgenic plants was sharply decreased, indicating that the altered plant coloration of the transgenic beet plants may be caused by the changed betacyanins content. The tyrosinase study suggested that the sharply decreased of betacyanins content in transgenic plants was caused via the decreased tyrosinase level. Therefore, the reason for the altered plant coloration may be due to partial inhibition of betacyanin biosynthesis that was induced via the pleiotropic roles of PttKN1 gene.

    Plants harbor complex and variable microbial communities. Using molecular-based techniques targeting the 16S rRNA gene, we studied the developmental stages and geographical location diversity of endophytic archaea in two locations (Shihezi and Changji) and four periods (the seedling growth, rosette formation, tuber growth and sucrose accumulation sampling periods) in the north slope of Tianshan Mountain, China. Community structure of mixed sample from 60 sugar beet plants was examined using PCR-based 454 pyrosequencing and terminal restriction fragment length polymorphism (T-RFLP). In total, 5290 archaea 16S rRNA sequences were obtained from all sugar beet samples. The most abundant archaea groups in all sugar beet were Methanococci, the miscellaneous Crenarchaeotic Group and Thermoplasmata. There was a marked difference in diversity of endophytic archaea in sugar beet for different growth periods. The greatest number of Operational T-RFLP Units (OTUs) was detected during sucrose accumulation (298) and rosette formation (282). Endophytic archaea diversity was reduced during seedling growth (128 OTUs) and tuber growth (55 OTUs). Nine OTUs were common to all four periods of growth. There were more OTUs in Shihezi than in Changji. Clustering analysis and principal component analysis of T-RFLP data revealed distinct shifts in endophytic archaea community profiles that corresponded to plant growth stage rather than geographical location. The dynamics of endophytic archaea communities were influenced by plant growth stage. To our knowledge, this is the first report that archaea has been identified as endophytes associated with sugar beet by the culture-independent approach. The results suggest that the diversity of endophytic archaea is abundant in sugar beet. PMID:25862354

    1996-01-01

    A collaborative study of the site-specific natural isotope fractionation-nuclear magnetic resonance (SNIF-NMR) method for detecting added beet sugar in fruit juices is reported. This method is complementary to the stable carbon isotope ratio analysis (SCIRA) (AOAC Official Methods 981.09 and 982.21), which can detect sugars derived from plants exhibiting C4 metabolism (corn and sugarcane). It is based on the fact that the deuterium content at specific positions of the sugar molecules is higher in fruit sugars than in beet sugar. The fruit juices are fermented, and the alcohol is distilled with a quantitative yield and analyzed with a high-yield NMR spectrometer fitted with a deuterium probe and fluorine lock. The proportion of ethanol molecules monodeuterated on the methyl site is recorded. This parameter (D/H)I is lowered when beet sugar is added to a fruit juice or concentrate. The precision of that method for measuring (D/H)I was observed to be similar to that of other isotope ratio methods: Sr values ranged from 0.19 to 0.25 ppm and SR values varied between 0.21 and 0.37 ppm. An excellent correlation was observed between the percentage of added beet sugar and the (D/H)I isotope ratio measured in this collaborative study. Consequently, all samples in which beet sugar was added were found to have a (D/H)I isotope ratio significantly below the normal value for authentic juice or concentrate of that fruit. The SNIF-NMR method for detection of added beet sugar in fruit juices has been adopted by AOAC INTERNATIONAL. PMID:8757451

    The purpose of this study was to produce and characterize core-shell biopolymer particles based on electrostatic deposition of an anionic polysaccharide (beet pectin) onto amphoteric protein aggregates (heat-denatured beta-lactoglobulin [beta-lg]). Initially, the optimum conditions for forming stable protein particles were established by thermal treatment (80 degrees C for 15 min) of 0.5 wt% beta-lg solutions at different pH values (3 to 7). After heating, stable submicron-sized (d=100 to 300 nm) protein aggregates could be formed in the pH range from 5.6 to 6. Core-shell biopolymer particles were formed by mixing a suspension of protein aggregates (formed by heating at pH 5.8) with a beet pectin solution at pH 7 and then adjusting the pH to values where the beet pectin is adsorbed (< pH 6). The impact of pH (3 to 7) and salt concentration (0 to 250 mM NaCl) on the properties of the core-shell biopolymer particles formed was then established. The biopolymer particles were stable to aggregation from pH 4 to 6, but aggregated at lower pH values because they had a relatively small -potential. The biopolymer particles remained intact and stable to aggregation up to 250 mM NaCl at pH 4, indicating that they had good salt stability. The core-shell biopolymer particles prepared in this study may be useful for encapsulation and delivery of bioactive food components or as substitutes for lipid droplets. PMID:19241582

  10. Long term fermentation studies about the nutritional requirements for biogasification of fodder beet silage as mono-substrate

    International Nuclear Information System (INIS)

    Two lab-scale, mesophilic anaerobic digesters (namely reactors R-1 and R-2) were operated simultaneously for continuous production of biogas from fodder beet silage as mono-substrate. The digesters were operated by a control system, developed at HAW Hamburg, which allowed an automatic auto-feeding up to a given maximum set-point. Within a period of 400 days of investigation, the hydraulic retention time (HRT) for reactor R-1 was adjusted to 10-12.5 days, and for reactor R-2, only to 6 days. The organic loading rate (OLR) varied with the total solids (TS) content of the harvest charge, ranging between 3.5 and 5 kg VS m-3 d-1. Although both digesters were run under stable conditions, indicated by low volatile fatty acids (VFA) concentrations below 200 mg l-1, the specific gas production rate (spec. GPR) declined over time to 0.55 and 0.40 l g VS-1 d-1, for R-1 and R-2, respectively. Therefore, it seemed that some nutrients were deprived, particularly in reactor R-2, which had a short HRT of 6 days. After supplementation with phosphate and sulphate, the improvement of the spec. GPR was 11% for reactor R-1, and 20% for reactor R-2. Simultaneously performed anaerobic batch digestion test series with the beet silage also confirmed the positive effect of these nutrients on the spec. GPR. Furthermore, quantitative microscopic counts exhibited that the addition of these nutrients had no significant effect on the performance of reactor R-1, but the number of the fluorescent methanogenic bacteria increased four-fold in the high throughput reactor R-2, after supplementation with phosphate. However, additional supplementation with sulphate had no further effect on the performance of R-2. Therefore, phosphate seems to be the limiting macro-nutrient for anaerobic digestion of fodder beet silage, especially under high loading conditions.

  12. Effect of pre sowing gamma irradiation on yield and quality traits of sugar beet multi germ varieties

    International Nuclear Information System (INIS)

    In this study which was carried out during two growing seasons in the experimental farm of the atomic energy authority, Egypt, seeds of the sugar beet varieties gloria and vital were subjected to different gamma irradiation doses from 0.0 to 1000 gray. Obtained results indicate that dosages up to 400 gray affected insignificantly on germination percent, while the higher doses had a progressive depression on the percentage of the germinated seeds of the both varieties. Stimulating effect of gamma irradiation on seeding height and seeding fresh weight was clearly shown following irradiating vital seeds with 100 or 200 gray, while marked reduction in mean values of these traits was noticed both varieties in the treatments of 500 gray or more. Considerable increases in root and leaves yield/plant of vital and gloria were detected after the application of 200 and 300 gray, respectively seeds received 500 gray or more gave plants with low productivity of roots and leaves. The chemical constituent of sugar beet roots was markedly influenced by gamma ray treatments, a dose of 400 gray existed a favourable and pronounced effect on sucrose content of the couple varieties, while the stimulating effects of gamma dosages on purity % of vital and gloria occurred at the higher doses of 500 and 750 gray. On the contrary, these dosages decreased remarkable the total soluble solids %. Based on the exhibited results, it could be concluded that performing gamma rays at dosages located between 200 and 400 gray may be of significant role in enhancing the quantitative and qualitative characteristics of sugar beet genotypes. 2 tabs

    Background Sugar beet (Beta vulgaris) is a crop cultivated for its high content in sugar, but it is vulnerable to many soil-borne pathogens. One of them is the basidiomycete Rhizoctonia solani. This fungal species has a compatibility system regulating hyphal fusions (anastomosis). Consequently, R. solani species are categorized in anastomosis groups (AGs). AG2-2IIIB isolates are most aggressive on sugar beet. In the present study, we report on the draft genome of R. solani AG2-2IIIB using the...

    Sugar syrup and molasses from beet processing containing 620 and 570 mg/ml sucrose, respectively, were assayed as low-cost and available substrates for the enzymatic synthesis of fructo-oligosaccharides (FOS). A commercial pectinase (Pectinex Ultra SP-L, from Aspergillus aculeatus) characterised by the presence of a transfructosylating activity, was used as biocatalyst. The FOS production increased when lowering the initial pH value of syrup (7.5) and molasses (8.9) to 5.5. Sugar syrup and mo...

  16. Gas chromatographic mass spectrometric analysis of n-hexane fraction of the leaves of sugar beets (beta vulgarus)

    International Nuclear Information System (INIS)

    The n-hexane fraction of the leaves of sugar beet was analyzed qualitatively and quantitatively using GC-MS and GC equipped with FID in separate experiments. The crude was extracted using ethanol and fractionated by n-hexane, ethyl acetate and chloroform in the increasing order of polarity. Only the n-hexane fraction was analyzed using GC-MS and GC equipped with FID. The nature of products was confirmed using total ion chromatograms as well as fragmentation pattern. The concentration of the major compounds was determined using the peak area. The n-hexane fraction was found to contain esters in addition to small quantities of other compounds. (author)

  17. Technological properties of sugar beets following pre-sowing gamma ray and fast neutron treatments of the seeds

    International Nuclear Information System (INIS)

    The effect of ionizing radiation (gamma rays and fast neutrons) and its aftereffect in the following generation on the technological properties of various sugar beet cultivars, strains and crosses was studied. The stimulating doses of radiation rarely affected the technological properties of the raw stuff. Purity of the juice and soluble ash insignificantly altered in different directions, while harmful nitrogen content increased. Pre-sowing seed treatment of the cultivars, strains, and crosses tested did not improve the technological properties. In certain cases these properties even slightly deteriorated. The aftereffect of ionizing radiation on the technological properties of the following generation was variably manifested

    Stunted growth of fall-sown sugar beets (Beta vulgaris) associated with high incidence of crownroot infections and large soil infestations by Ditylenchus dipsaci were observed at the end of the crop growing season in southern Spain by early June 2005. The largest proportion (75%) of the nematode life-stages in plant and soil was the fourth-stage juvenile. The large number (up to 3,750 nematodes per gram of fresh tissue) of D. dipsaci individuals and severe anatomical alterations observed in s...

  19. Effect of the laser exposure of seeds on the yield and chemical composition of sugar beet roots

    International Nuclear Information System (INIS)

    The results of the research showed beneficial effects of the laser pre-sowing stimulation of sugar beet seeds. In all the combination concerning the biostimulated seeds, the yield of roots was elevated from 3.2 to 4.5 t/ha, which means an 8-10% increase when compared to the control seeds. The sugar content was also elevated after the laser biostimulation, which caused an increase in the biological yield for about 1 t/ha independently of the variety in comparison with the control.

    Full Text Available In this paper the bioethanol production in batch culture by free Saccharomyces cerevisiae cells from thick juice as intermediate product of sugar beet processing was examined. The obtained results suggest that it is possible to decrease fermentation time for the cultivation medium based on thick juice with starting sugar content of 5-15 g kg-1. For the fermentation of cultivation medium based on thick juice with starting sugar content of 20 and 25 g kg-1 significant increase in ethanol content was attained during the whole fermentation process, resulting in 12.51 and 10.95 dm3 m-3 ethanol contents after 48 h, respectively. Other goals of this work were to investigate the possibilities for experimental results prediction using artificial neural networks (ANNs and to find its optimal topology. A feed-forward back-propagation artificial neural network was used to test the hypothesis. As input variables fermentation time and starting sugar content were used. Neural networks had one output value, ethanol content, yeast cell number or sugar content. There was one hidden layer and the optimal number of neurons was found to be nine for all selected network outputs. In this study transfer function was tansig and the selected learning rule was Levenberg-Marquardt. Results suggest that artificial neural networks are good prediction tool for selected network outputs. It was found that experimental results are in very good agreement with computed ones. The coefficient of determination (the R-squared was found to be 0.9997, 0.9997 and 0.9999 for ethanol content, yeast cell number and sugar content, respectively.

  1. Complexation of bovine serum albumin and sugar beet pectin: stabilising oil-in-water emulsions.

    In a previous study (Langmuir 28 (2012) 10164-10176.), we investigated the complexation of bovine serum albumin (BSA) with sugar beet pectin (SBP). A pH-composition phase diagram was established and structural transitions in relation to the phase diagram during complexation were identified. The present study examines the implications of these interactions on the emulsifying performance of BSA/SBP mixtures. Middle-chain triglycerides (MCTs) in water emulsions were prepared using conditions corresponding to different regions of the phase diagram. At high pHs and in the stable region of mixed individual soluble polymers where complexation is absent, there is no improved emulsifying performance, compared with the individual protein and polysaccharide. For these mixtures, the emulsion characteristics are controlled by the major component in the solutions, as determined by the competitive adsorption of the two components at the oil-water interface. At low pHs and low BSA/SBP ratios, and so mainly within the stable region of intramolecular soluble complexes, BSA/SBP mixtures greatly improve the stability of emulsions. Here, stabilisation is controlled by the cooperative adsorption of the two components at the oil-water interface. Through electrostatic complexation BSA promotes the adsorption of SBP on to interfaces to form a thick steric layer around emulsion droplets and thus providing better stability. At low pHs and high BSA/SBP ratios, that is, mainly within the unstable region of intermolecular insoluble complexes, emulsions prepared are extremely unstable due to bridging flocculation between emulsion droplets.

    Three cell lines (QAU-Se-E-1, -2 and -3, or Se-1, -2 and -3 for short) were established from eggs of beet armyworm (Spodoptera exigua) that have been passaged stably for more than 60 times in TNM-FH medium supplemented with 10 % fetal bovine serum. The cell lines consisted of round and spindle-shaped cells. The round cells accounted for 96.82, 84.34 and 83.16 % of the cells in the three cell lines, respectively, with cell diameters of 16.21 ± 0.72, 15.63 ± 0.58 and 13.06 ± 0.44 μm. Random amplified polymorphic DNA and analysis of the CO I gene showed that the three cell lines were all derived from S. exigua. Growth curves at passage 30 were determined and the results showed that the cell population doubling times were 59.03, 49.08 and 49.91 h, respectively. The three cell lines can be infected by S. exigua multiple nucleopolyhedrovirus (SeMNPV). Se-3 was extremely susceptible to the virus with an infection rate of 97.52 % 4 days after the inoculation and produced 2.02 × 10(6) OBs per mL of culture. Flow cytometry analysis showed that some of Se-1 and Se-2 cells had apoptosis after infection, whereas Se-3 cells did not. Bioassays showed that the virulence of the SeMNPV proliferated from Se-3 was similar to that from the insect with LC50 of 5.55 × 10(5) and 2.64 × 10(5) OBs/mL. Therefore, the cell lines can be used to study the SeMNPV-host interactions and mechanisms underlying the interactions. PMID:25999173

  3. Flowering time in wild beet ( Beta vulgaris ssp. maritima) along a latitudinal cline

    Dijk, Henk Van; Boudry, Pierre; McCombre, Helen; Vernet, Philippe

    The wild beet ( Beta vulgaris ssp. maritima, a perennial species from the Mediterranean and the European Atlantic coasts) shows marked variation in flowering time in terms of both the year of first flowering and flowering date in a given year. Much of this variability is related to latitude. Beta vulgaris plants flower either in the same year as they germinate or in their second year. This is mainly due to differences in their requirement for vernalization, which is determined by a single gene B/b and by quantitative trait loci. The more southern the origin of the plants, the less vernalization is required. Also the B allele, which cancels vernalization requirement completely, has a high frequency in the Mediterranean region, but is completely absent in the northern part of the distribution of this species. We found that flowering date variation in relation to the latitude of origin is maintained under greenhouse conditions but does not follow a simple clinal relationship. From the Mediterranean northwards to the west coast of Brittany, flowering occurs progressively earlier, but from Brittany northwards to south-east England and The Netherlands it is progressively later. A possible explanation for this difference is that in the southern part of the range sensitivity to daylength and warmth control flowering time, whereas further north vernalization requirement is also a key factor. A substantial part of all differences in flowering time was heritable: heritability within populations was measured as 0.33 under greenhouse conditions. The high heritability implies evolutionary change may occur in this character.

  4. GAMMA IRRADIATION OF SUGAR BEET SEEDS INDUCED PLANT RESISTANCE TO ROOT-KNOT NEMATODE MELOIDOGYNE INCOGNITA

    International Nuclear Information System (INIS)

    The main objective of this study was to investigate the effect of irradiation of sugar beet seeds on the plant resistance to root-knot nematode Meloidogyne incognita infection in addition to some morphological parameters, biochemical components and root technological characters. Relative to control (non-irradiated seeds), the obtained data showed that, all doses except 10 Gy significantly increased root length of un inoculated plants and the most effective dose was 200 Gy. All doses significantly decreased root diameter except 50 and 100 Gy. The 10 and 400 Gy significantly reduced root fresh weight while 50, 100 and 200 Gy caused non-significant increase. All doses significantly increased root fresh weight/dry weight than control. There was non-significant effect on the morphological parameters of the plants germinated from gamma irradiated seeds and inoculated with Meloidogyne incognita. Total chlorophyll of seed irradiated and un inoculated plants were significantly reduced by all doses except 200 Gy. All doses of gamma radiation caused non-significant decrease in the total chlorophyll of the infected plants. In un inoculated plants, a significant reduction in the total phenol was occurred due to all doses of gamma radiation. In contrast, in inoculated plants, 10 and 25 Gy caused significant reduction in the total phenol while 50 and 400 Gy caused significant increase in the total phenol.Significant increase in sucrose % was observed due to 10 Gy in the un inoculated plants. The 400 Gy caused significant decrease while other doses caused non-significant decrease in the sucrose %. In the inoculated plants, 50, 100 and 400 Gy caused significant increase in sucrose %. All doses significantly increased total soluble salts percent (TSS %) of either inoculated or un inoculated plants. Purity % was increased by all doses in the inoculated plants.The number of galls and egg masses were reduced gradually by increasing gamma doses and 100 Gy caused the highest reduction 89

    A critical step in the bioprocessing of sustainable biomass feedstocks, such as sugar beet pulp (SBP), is the isolation of the component sugars from the hydrolysed polysaccharides. This facilitates their subsequent conversion into higher value chemicals and pharmaceutical intermediates. Separation methodologies such as centrifugal partition chromatography (CPC) offer an alternative to traditional resin-based chromatographic techniques for multicomponent sugar separations. Highly polar two-phase systems containing ethanol and aqueous ammonium sulphate are examined here for the separation of monosaccharides present in hydrolysed SBP pectin: l-rhamnose, l-arabinose, d-galactose and d-galacturonic acid. Dimethyl sulfoxide (DMSO) was selected as an effective phase system modifier improving monosaccharide separation. The best phase system identified was ethanol:DMSO:aqueous ammonium sulphate (300gL(-1)) (0.8:0.1:1.8, v:v:v) which enabled separation of the SBP monosaccharides by CPC (200mL column) in ascending mode (upper phase as mobile phase) with a mobile phase flow rate of 8mLmin(-1). A mixture containing all four monosaccharides (1.08g total sugars) in the proportions found in hydrolysed SBP was separated into three main fractions; a pure l-rhamnose fraction (>90%), a mixed l-arabinose/d-galactose fraction and a pure d-galacturonic acid fraction (>90%). The separation took less than 2h demonstrating that CPC is a promising technique for the separation of these sugars with potential for application within an integrated, whole crop biorefinery.

    The aim of this work was to study the effects of incorporating sugar beet pulp (SBP) into the diet on the development of the crop and performance of geese. A total of 480 1-day-old ganders were divided into three groups differing in the composition and mode of distribution of the diet offered from day 56 to 89. The following two diets were used: a standard diet (nitrogen-corrected apparent metabolizable energy, AMEn 11.44 MJ/kg; 160 g/kg CP) or a diet containing 10% of SBP (SBP diet; AMEn 11.47 MJ/kg; 160 g/kg CP). The swelling capacity (SC) hydration was higher for SBP than for the standard diet (3.62 v. 2.72 ml of H2O/g of dry matter at 60 min; P0.05). At day 89, the volume of the crop tended to be higher in the SBPt compared with the Control group (52.8 v. 48.8 ml/kg of LW; P=0.101). After overfeeding, feed intake (12 922 g), weight gain (2412 g), LW (8170 g), fatty liver weight (875 g) and commercial grading of the fatty liver were similar (P>0.1) for all the three groups. Therefore, SBP could help adapt the digestive tract of waterfowl to high feed intake through an increase in the crop volume, but its method of use - that is, level of incorporation and mode of distribution - should continue to be investigated.

    Sixteen post-harvest upregulated genes from sugar beet comprising five novel sequences were isolated by subtractive cloning. Transcription profiles covering a period of up to 49 days after harvest under controlled storage conditions and in field clamps are reported. Post-harvest induced genes are involved in wound response, pathogen defense, dehydration stress, and detoxification of reactive oxygen species. An early induction of a cationic peroxidase indicates a response to post-harvest damage. Wound response reactions may also involve genes required for cell division such as a regulator of chromatin condensation and a precursor of the growth stimulating peptide phytohormone phytosulfokine-alpha. Surprisingly, also three putative non-protein coding genes were isolated. Two of these genes show intron specific and storage temperature dependent splicing of a precursor mRNA. The temperature dependent splicing of an intron containing sugar beet mRNA is also maintained in transgenic Arabidopsis thaliana. The storage induced genes are integrated into a model that proposes the response to several post-harvest stress conditions. Temperature regulated splicing may be a mechanism to sense seasonal temperature changes. PMID:18324413

    This work investigated the effects of gamma irradiation on the shelf-life extension and safety of minimally processed red beet (Beta vulgaris ssp. vulgaris L.) by performing microbiological, chemical and sensory analyses. Red beets were harvested 73 days after transplanting and their tuberous parts were minimally processed and separated in two groups: control (non-irradiated) and irradiated (0.5, 1.0 and 1.5 kGy). Tests for Salmonella sp., total and fecal coliforms, total count of aerobic mesophilic and lactic-acid bacteria were performed during the 21-day storage at 8 deg C. They indicated that the samples irradiated with 1.0 and 1.5 kGy remained in good conditions throughout storage while the unirradiated samples did not last 7 days. Chemical analyses indicated that the concentrations of vitamins B1 and B2 were not affected by irradiation. In contrast the amounts of fructose and glucose increased during storage while the one for sucrose decreased. In addition four series of sensory evaluations including appearance and aroma indicated that the samples irradiated with 1.0 and 1.5 kGy remained good for consumption for 20 days. Therefore it was concluded that the use of the doses of 1.0 and 1.5 kGy produced the best effects on the conservation of the samples without harming the sensory characteristics and nutritional constituents tested.

    The nutrient composition and enzyme activities in larvae of the beet armyworm, Spodoptera exigua (Hbner), fed on high, medium or low gossypol cotton cultivars were examined at different time intervals. Significantly lower free fatty acid was observed in larvae fed for 6 h on high gossypol ’M9101’ compared to larvae fed on the low (ZMS13) and intermediate (HZ401) gossypol cultivars. Significantly higher trypsin activity was observed in larvae fed on high gossypol ’M9101’ for 24 h compared to those fed for 1, 4 and 6 h. Significantly higher catalase and total superoxide dismutase enzyme activities were observed in larvae of S. exigua fed on high gossypol ’M9101’ compared with low gossypol cultivars ’ZMS13’ and ’HZ401’ for 1, 4, 6 and 24 h. However, significantly lower carboxylesterase and acetylcholinesterase enzyme activities were found in larvae fed on high gossypol ’M9101’ compared with the other cultivars for 1, 4, 6 and 24 h. The interaction between cotton variety and beet armyworm infestation time significantly affected the carboxylesterase enzyme activity in S. exigua. The characterization of the effects of plant allelochemicals on herbivorous larvae is important for aiding understanding of plant-insect interaction as well as in devising solutions to pest problems by breeding plant resistance, identifying metabolic targets for insecticide development, etc.

    Full Text Available The applicability of Peleg equation was examined for the description of mass transfer during osmotic dehydration (OD of apple in sugar beet molasses. Mass transfer was investigated in terms of water loss (WL and solid gain (SG, during OD in 40-80% sugar beet molasses solutions, at 45, 55 and 65ºC. High regression coefficients obtained for Peleg constants (R2>0.975 indicate good fit to the experimental data. The Peleg rate constant varied from 0.144 to 0.785 (g/g i.s.w. and from 2.006 to 4.436 (g/g i.s.w. for WL and SG, respectively. The Peleg capacity constant varied from 1.142 to 1.553 (h g/g i.s.w. and from 8.254 to 11.930 (h g/g i.s.w. for WL and SG, respectively. The equilibrium WL∞ and SG∞ were estimated using the Peleg model. In addition, the activation energy (Ea for WL and SG was determined from the relationship between the Peleg rate constant and Arrhenius equation.

    The uptake of sodium into protoplasts of quince (Cydonia oblonga Mill, clone BA29), sugar beet (Beta vulgaris L. cv. Monohill), and wheat (Triticum aestivum L. cv. Kadett) was determined by use of the acetoxy methyl ester of the fluorescent sodium-binding benzofuran isopthalate (SBFI-AM). In the presence of 1 mM CaCl2, little sodium was taken up in the cytosol of quince mesophyll cells compared to cytosols of sugar beet and wheat. Upon addition of 40 mM NaCl, approximately the same amount of sodium was taken up in leaf and root protoplasts of wheat, but no sodium was taken up in quince. However, in calcium-free medium, obtained by addition of ethylene glycol tetra acetic acid (EGTA), quince protoplasts transiently took up sodium in the cytosol when 200-400 mM NaCl was added to the protoplast medium. Moreover, after cultivation of quince in the presence of 200 mM sodium for 4 weeks, the cytosol of isolated protoplasts did not take up any sodium at all from a calcium-free medium. The results show that protoplasts from salt tolerant quince only temporarily take up sodium in the cytosol and that they have a mechanism for fast extrusion of sodium from that compartment. These mechanisms are probably important for the high salt tolerance of quince. Calcium blocks the sodium uptake into the cytosol of both quince and wheat protoplasts. PMID:15900884

    2014-03-01

    Full Text Available Using potted sugar beet plants we aimed to investigate the suitability of four fluorescence indices to detect and differentiate the impact of nitrogen supply, water deficit and powdery mildew in two sugar beet cultivars (Beta vulgaris L.. Plants were grown inside a polytunnel under two nitrogen levels combined with water deficit or full irrigation. Changes in plant physiology were recorded at two physiological stages with a multiparametric handheld fluorescence sensor and a fluorescence imaging system. The analysis of chlorophyll content and osmotic potential served as reference. Based on our results, the fluorescence indices “Nitrogen Balance Index” and “Simple Fluorescence Ratio” responded quite sensitively to drought stress and mildew infection. Moreover, the blue-to-far-red fluorescence ratio revealed significant stress-induced alterations in the plant physiology. In all, fluorescence indices might be used as single or combined indices for successful stress sensing. However, a robust stress differentiation by using only one fluorescence ratio could not be accomplished.

  13. Response of sugar beet plants to ultraviolet-B (280-320 nm) radiation and Cercospora leaf spot disease

    International Nuclear Information System (INIS)

    Sugar beet (Beta vulgaris L.) plants injected with Cercospora beticola Sacc. as well as non-infected plants were grown under visible light with or without ultraviolet-B (UV-B, 280-320 nm) radiation for 40 days. An interaction between UV-B radiation and Cercospora leaf spot disease was observed, resulting in a large reduction in leaf chlorophyll content, dry weight of leaf laminae, petioles and storage roots. Lipid peroxidation in leaves also increased the most under the combined treatments. This was also true for ultraweak luminescence from both adaxial and abaxial leaf surfaces. However, no correlation between lipid peroxidation and ultraweak luminescence was observed. Ultraviolet-B radiation given alone appeared to have either a stimulating effect, giving an increase in dry weight of laminac and reducing lipid peroxidation, or no effect. This lack of effect was seen in the absence of change in dry weight of storage roots and chlorophyll content relative to controls. The study demonstrated a harmful interaction between UV-B radiation and Cercospora leaf spot disease on sugar beet

    Some characteristics of nitrate reductase from sugar beet leaves shown in this paper were as follows:The nitrate reductase from sugar beet leaves required NADH as an electron donor.Accordingly,the nitrate reductase was classified as NADH-dependent(E.C.1.6.61).The Km value of the nitrate reductase for NADH and NO3- were 0.86m mol and 0.18μ mol respectively.The optimum pH in reaction mixture solution for nitrate reduction activity was 7.5.The effect of variable concentrations of inorganic phosphorus in the reaction buffer on nitrate reductase activity was investigated.When the inorganic phosphorus concentration was below 35m mol,the nitrate reductase activity was increased with increase of inorganic phosphorus concentration.Conversely,when the inorganic phosphorus concentration was over 35m mol,the nitrate reductase activity was inhibited.The nitrate reductase activity assayed in vitro was 3.2 and 5.6times of that assayed in vivo under the condition of exogenous and endogenous ground substance respectively.

  15. Further characterization of the red beet plasma membrane Ca2+-ATPase using GTP as an alternative substrate

    International Nuclear Information System (INIS)

    The GTP-driven component of Ca2+ uptake in red beet (Beta vulgaris L.) plasma membrane vesicles was further characterized to confirm its association with the plasma membrane Ca2+-translocating ATPase and assess its utility as a probe for this transport system. Uptake of 45Ca2+ in the presence of GTP demonstrated similar properties to those previously observed for red beet plasma membrane vesicles utilizing ATP with respect to pH optimum sensitivity to orthovanadate, dependence on Mg:substrate concentration and dependence on Ca2+ concentration. Calcium uptake in the presence of GTP was also strongly inhibited by erythrosin B, a potent inhibitor of the plant plasma membrane Ca2+-ATPase. Furthermore, after treatment with EGTA to remove endogenous calmodulin, the stimulation of 45Ca2+-uptake by exogeneous calmodulin was nearly equivalent in the presence of either ATP or GTP. Taken together these results support the proposal that GTP-driven 45Ca2+ uptake represents the capacity of the plasma membrane Ca2+-translocating ATPase to utilize this nucleoside triphosphate as an alternative substrate. When plasma membrane vesicles were phosphorylated with [γ-32P]GTP, a rapidly turning over, 100 kilodalton phosphorylated peptide was observed which contained an acyl-phosphate linkage. While it is proposed that this peptide could represent the catalytic subunit of the plasma membrane Ca2+-ATPase, it is noted that this molecular weight is considerably lower than the 140 kilodalton size generally observed for plasma membrane Ca2+-ATPases present in animal cells

    Rhizoctonia solani causes crown rot of sugar beets, a severe disease that has destroyed up to 60% of the plants in a test field in western Nebraska. Laetisaria arvalis, a natural hyperparasite of Rhizoctonia spp., was isolated from fields in western Nebraska. To test for the potential for biological control of R. solani, in November 1980 (following harvest) we applied various combinations of a nematicide (Telone II; Dow Chemical Co.), a nutrition source (sugar beet pulp), and an inoculum of L. arvalis in a randomized block design. Populations of R. solani, L. arvalis, and sugar beets were monitored monthly through October 1981 (just after harvest). In control and nematicide plots, the R. solani population did not change significantly through time. In plots inoculated with L. arvalis, the R. solani populations declined through March, concomitant with an increase in L. arvalis. L. arvalis then declined with a corresponding increase in the R. solani populations. Beet plant numbers declined significantly in all treatments. We suggest that reduction of the R. solani populations with the hyperparasite L. arvalis is possible but that a stable equilibrium naturally exists. PMID:16346925

    Full Text Available The damping off is the main disease that affects the beet crop during the seedling production. The aim of this study was to evaluate different salicylic acid (SA concentrations for resistance induction against damping-off in beet seedling and its antifungal activity against Fusarium sp., in vitro condition. Treatment of beet seed was with SA solution by immersion during 5 minutes in the 0.5, 1.0, 1.5 and 2.0 mM concentrations and control (distilled water. It was used four replications with 20 cells by experimental unit. The experiment was carried out for 14 days in cultivate chamber with temperature (23 oC ± 2°C, lighting (12 hours photoperiod and humidity (70% ± 10% controlled. After this time, the germination, damping off incidence, seedling length and fresh mass matter weight were evaluated. It was evaluated also in the seedling tissue the phenylalanine ammonia-lyase (PAL, ?-1.3 glucanase and chitinase level enzymes. In the in vitro the SA was putted in PDA (potato-dextrose-agar medium, where the Fusarium sp. mycelial growth was evaluated. The SA applied for seeds treatment didn’t had effect significant on damping off of beet seedlings, but it induced the activity of ?-1.3 glucanase enzyme, it being this higher in nine times when compared the treatment control. The SA acted in the Fusarium sp. in vitro control with fungitoxic action, suppressed mycelial growth in 28% if compared to control.

    Salinity is one of the major abiotic stresses that limit the growth and productivity of sugar beet (Beta vulgaris L.). To improve sugar beet's salinity tolerance, the ZxNHX and ZxVP1-1 genes encoding tonoplast Na(+)/H(+) antiporter and H(+)-PPase from xerophyte Zygophyllum xanthoxylum were co-expressed by Agrobacterium tumefaciens-mediated transformation. It is showed here that co-expression of ZxNHX and ZxVP1-1 confers enhanced salinity tolerance to the transformed sugar beet plants compared with the wild-type (WT) plants. The chimeric plants grew well in the presence of high salinity (400 mM NaCl), whereas WT plants displayed chlorosis and died within 8 days. Compared to WT plants, the chimeric plants co-expressing ZxNHX and ZxVP1-1 accumulated more proline, Na(+) and K(+) in their leaves and petioles when exposed to high salinity, which caused lower solute potential, retained more water and thus subjected to lesser cell membrane damage. Interestingly, the chimeric plants accumulated higher sucrose, glucose and fructose contents in their storage roots than WT plants in the absence or presence of high salinity. Our results suggested that co-expression of ZxNHX and ZxVP1-1 improved the osmoregulatory capacity in chimeric sugar beet through increased compartmentalization of ions into the vacuoles by enhancing the activity of proton pumps and thus mitigated Na(+)-toxicity for plants.

    Full Text Available Background: L-tryptophan is an important ingredient in medicines, especially in neuromedicines such as antidepressants. Many commercial processes employ various microorganisms with high tryptophan synthase activity to produce L-tryptophan from indole and L-serine, but these processes are very costly due to the costs of precursors, especially L-serine. Objectives: For this reason, we studied the ability to use processed Iranian cane and beet molasses as L-serine sources for L-tryptophan production, which enables us to reach a cost-effective process. Materials and Methods: Whole cells of Escherichia coli ATCC 11303 were induced for L-tryptophan synthase by addition of indole to the growth medium and bacterial cells harvested from the growth medium were used as biocatalysts in the production medium. Conditions of the production medium were optimized and Iranian cane and beet molasses were processed by solvent extraction with ethanol and n-butanol and used as L-serine sources of the production medium. Amount of L-tryptophan and theoretical yield of L-tryptophan production were determined by High Performance Liquid Chromatography and by a colorimetrical method on the basis of the remaining indole assay, respectively. Results: L-tryptophan production increased by 15 folds, when indole was used as an inducer. L-tryptophan was produced from processed Iranian beet molasses in satisfactory amounts (0.53 mM and no exogenous pyridoxal phosphate was required as a cofactor under our experimental conditions. Conclusions: The obtained results proved that Iranian beet molasses include significant amounts of L-serine that makes them a suitable substitution for L-serine. Findings of the present study give impetus to use of Iranian beet molasses for cost-effective L-Trp production in the amino acid industry. Keywords: Tryptophan; Tryptophan Synthase; Indole

    Results of a collaborative study are reported for the detection of added beet or cane sugar in maple syrup by the site-specific natural isotope fractionation-nuclear magnetic resonance (SNIF-NMR) method. The method is based on the fact that the deuterium content at specific positions of the sugar molecules is different in maple syrup from that in beet or cane sugar. The syrup is diluted with pure water and fermented; the alcohol is distilled with a quantitative yield and analyzed with a high-field NMR spectrometer fitted with a deuterium probe and fluorine lock. The proportion of ethanol molecules monodeuterated at the methyl site is recorded. This parameter (D/H)I is decreased when beet sugar is added and increased when cane sugar is added to the maple syrup. The precision of the method for measuring (D/H)I was found to be in good agreement with the values already published for the application of this method to fruit juice concentrates (AOAC Official Method 995.17). An excellent correlation was found between the percentage of added beet sugar and the (D/H)I isotopic ratio measured in this collaborative study. Consequently, all samples in which exogenous sugars were added were found to have a (D/H)I isotopic ratio significantly different from the normal value for an authentic maple syrup. By extension of what is known about plants having the C4 cycle, the method can be applied to corn sweeteners as well as to cane sugar. One limitation of the method is its reduced sensitivity when applied to specific blends of beet and cane sugars or corn sweeteners. In such case, the C13 ratio measurement (see AOAC Official Method 984.23, Corn Syrup and Cane Sugar in Maple Syrup) may be used in conjunction. PMID:11601471

  4. The effect of copper ions, aluminium ions and their mixtures on separation of pectin from the sugar beet juice

    Full Text Available In sugar industry there is a problem of the presence of undesirable macromolecules compounds such as pectin in sugar beet juice. The affinity of calcium ions commonly used in the sugar industry for the removal of pectin from the sugar beet juice is relatively small. Coagulation and precipitation of pectin can be performed by process of discharging that is chemically induced. Compounds with di- and trivalent cations such as pure CuSO4, Al2(SO43 or their mixtures can be applied for clarification of pectin colloidal systems. According to data from the order of pectin selectivity to divalent metal ions, Cu2+ ions are the first order of ion binding. Also, aluminum sulfate is commonly used in the waste water treatment. Two model solutions of pectin whose concentration corresponds to the concentration of these macromolecules in sugar beet juice (0.1% w/w are investigated. Using a method of measuring zeta potential, it was proven for both investigated pectin that fewer quantities of Cu2+ ions compared to the values of Al3+ ions are needed to reach zero zeta potential. In all the investigated coagulants and their mixtures, zeta potential has changed the sign. In experiments with mixtures has been shown that pure salts showed better coagulation properties. The reduced strength of binding of cations in the case of most of the applied mixture of Cu2+ and Al3+ ions, can be explained by the mutual competition of these ions for the adsorption site (COO- groups on the surface of macromolecules. Mixture with approximately equal shares of ions Cu2+ and Al3+ had the most unfavorable coagulation ability (ion antagonism. Mechanism of discharge as well as the model of double electric layer surrounding pectin macromolecules in the presence of mixtures of Cu2+ and Al3+ ions are suggested. However, due to possible undesirable effects of CuSO4 on food processing, Al2(SO43 is proposed instead of traditional coagulant CaO, not only because of lower consumptions of

    Genetic conflict between cytoplasmically inherited elements and nuclear genes arising from their different transmission patterns can be seen in cytoplasmic male sterility (CMS), the mitochondrion-encoded inability to shed functional pollen. CMS is associated with a mitochondrial open reading frame (ORF) that is absent from non-sterility inducing mitochondria (S-orf). Nuclear genes that suppress CMS are called restorer-of-fertility (Rf) genes. Post-transcriptional and translational repression of S-orf mediates the molecular action of Rf that encodes a class of RNA-binding proteins with pentatricopeptide repeat (PPR) motifs. Besides the PPR-type of Rfs, there are also non-PPR Rfs, but the molecular interactions between non-PPR Rf and S-orf have not been described. In this study, we investigated the interaction of bvORF20, a non-PPR Rf from sugar beet (Beta vulgaris), with preSatp6, the S-orf from sugar beet. Anthers expressing bvORF20 contained a protein that interacted with preSATP6 protein. Analysis of anthers and transgenic calli expressing a FLAG-tagged bvORF20 suggested the binding of preSATP6 to bvORF20. To see the effect of bvORF20 on preSATP6, which exists as a 250-kDa protein complex in CMS plants, signal bands of preSATP6 in bvORF20-expressing and non-expressing anthers were compared by immunoblotting combined with Blue Native polyacrylamide gel electrophoresis. The signal intensity of the 250-kDa band decreased significantly, and 200- and 150-kDa bands appeared in bvORF20-expressing anthers. Transgenic callus expressing bvORF20 also generated the 200- and 150-kDa bands. The 200-kDa complex is likely to include both preSATP6 and bvORF20. Post-translational interaction between preSATP6 and bvORF20 appears to alter the higher order structure of preSATP6 that may lead to fertility restoration in sugar beet. PMID:26031622

  6. Transcriptome Analysis and Screening for Potential Target Genes for RNAi-Mediated Pest Control of the Beet Armyworm, Spodoptera exigua.

    Full Text Available The beet armyworm, Spodoptera exigua (Hübner, is a serious pest worldwide that causes significant losses in crops. Unfortunately, genetic resources for the beet armyworm is extremely scarce. To improve these resources we sequenced the transcriptome of S. exigua representing all stages including eggs, 1(st to 5(th instar larvae, pupae, male and female adults using the Illumina Solexa platform. We assembled the transcriptome with Trinity that yielded 31,414 contigs. Of these contigs, 18,592 were annotated as protein coding genes by Blast searches against the NCBI nr database. It has been shown that knockdown of important insect genes by dsRNAs or siRNAs is a feasible mechanism to control insect pests. The first key step towards developing an efficient RNAi-mediated pest control technique is to find suitable target genes. To screen for effective target genes in the beet armyworm, we selected nine candidate genes. The sequences of these genes were amplified using the RACE strategy. Then, siRNAs were designed and chemically synthesized. We injected 2 µl siRNA (2 µg/µl into the 4(th instar larvae to knock down the respective target genes. The mRNA abundance of target genes decreased to different levels (∼20-94.3% after injection of siRNAs. Knockdown of eight genes including chitinase7, PGCP, chitinase1, ATPase, tubulin1, arf2, tubulin2 and arf1 caused a significantly high level of mortality compared to the negative control (P<0.05. About 80% of the surviving insects in the siRNA-treated group of five genes (PGCP, chitinase1, tubulin1, tubulin2 and helicase showed retarded development. In chitinase1-siRNA and chitinase7-siRNA administered groups, 12.5% survivors exhibited "half-ecdysis". In arf1-siRNA and arf2-siRNA groups, the body color of 15% became black 48 h after injections. In summary, the transcriptome could be a valuable genetic resource for identification of genes in S. exigua and this study provided putative targets for RNAi pest

    In this study, ultrasound-assisted extraction (UAE) of natural pigment extraction from waste red beet stalks were optimized under four factors (extraction temperature, ultrasonic power, extraction time and solid-liquid ratio) by using three level Box-Behnken response surface design. Extraction temperature, ultrasonic power and solid-liquid ratio were significantly influenced the extraction yield of pigments. Extraction temperature of 53 °C, ultrasonic power of 89 w, extraction time of 35 min and SL ratio of 1:19 g/ml was identified as the optimal condition. Under this condition, the actual yield of (betacyanin of 1.28 ± 0.02 and betaxanthin of 5.31 ± 0.09 mg/g) pigments was well correlated with predicted values (betacyanin was 1.29 mg/g and betaxanthin was 5.32 mg/g).

    Dried pellet of exhausted sugar beet cossettes were digested alone and combined with cow manure as co-substrate in a mesophilic semi-continuous anaerobic system. In single digestion assay, the stable biogas production and stable reactor operation was observed at the hydraulic retention time (HRT) of 20days (OLR: 3.26gVS/Lreactord) which was the minimum HRT tolerated by the system. However, co-digestion with cow manure allowed to decrease the HRT until 15days (OLR: 4.97gVS/Lreactord) with 32% higher biogas generation and efficient reactor operation. Propionic acid was the predominant VFA observed during single digestion assay failure, while acetic acid accumulation was observed in the co-digestion assay. In both single and co-digestion assays, the recovery of digesters was possible by ceasing the feeding and re-inoculation with a well-adapted inoculum. PMID:26512853

    Rhizoctonia solani is a widespread plant pathogenic fungus featuring a broad host range including several economically important crops. Accordingly, genome analyses of R. solani isolates are important to uncover their pathogenic potential. Draft genome sequences for four R. solani isolates representing three of the 14 R. solani anastomosis groups (AGs) are available. Here, we present the first draft genome sequence for an R. solani AG2-2IIIB isolate that is pathogenic on sugar beet. The fungal genome was assembled in 2065 scaffolds consisting of 5826 contigs amounting to a size of about 52 Mb which is larger than any other R. solani isolate known today. Genes potentially encoding cellulolytic, lignolytic and pectinolytic enzymes were identified. PMID:26851388

  10. Studies on sorption, desorption, regeneration and reuse of sugar-beet pectin gels for heavy metal removal

    International Nuclear Information System (INIS)

    This work reports the effectiveness of sugar-beet pectin xerogels for the removal of heavy metals (cadmium, lead and copper) after multiple batch sorption-desorption cycles, with and without a gels regeneration step. Metals were recovered from xerogel beads without destroying their sorption capability and the beads were successfully reused (nine cycles) without significant loss in both biosorption capacity and biosorbent mass. Metals uptake levelled off or increased after using a 1 M CaCl2 regeneration step after each desorption. Calcium, as a regenerating agent, increased the stability and reusability of the gels repairing the damage caused by the acid and removing the excess protons after each elution providing new binding sites. Because of their excellent reusability, pectin xerogels are suitable for metal remediation technologies.

    The feasibility of anaerobic co-digestion of sewage sludge (SS) and sugar beet pulp lixiviation (SBPL) was assessed. Mesophilic and thermophilic batch assays of five different SS/SBPL ratios were used to investigate the effect of temperature, providing basic data on methane yield and reduction in total volatiles. Microbe concentrations (Eubacteria and methanogenic Archaea) were linked to traditional parameters, namely biogas production and removal of total volatile solids (TVS). The relationship between Eubacteria and Archaea was analysed. Given equal masses of organic matter, net methane generation was higher in the mesophilic range on the biochemical methane potential (BMP) test. Methane yield, TVS removal data and high levels of volatile fatty acids provided further evidence of the best behaviour of the mesophilic range. At the end of testing the microbial population under of the reactors consisted of Eubacteria and Archaea, with Eubacteria predominant in all cases. PMID:25600010

  12. Importance of soil nitrogen and select intensifying measures in the soil-plant-fertilizer system demonstrated in sugar beets

    International Nuclear Information System (INIS)

    Sugar beets were gradually fertilized with 15N-labelled nitrogen fertilizer without or in combination with irrigation. To gain optimum crop yields 180 - 200 kg/ha fertilizer nitrogen were required. Within the range of maximum yield the total nitrogen uptake amounted to 300 - 360 kg/ha under conditions of irrigation. Nitrogen was taken up from the fertilizer by 40% and from the soil by 60%. The immobilization rate of fertilizer nitrogen was near 30% after 2 years of vegetation. Only 33% and 25%, resp., of soil nitrogen could be replaced by fertilizing without and combined with irrigation, resp. It was shown that despite of increased application of the main intensifying factors, nitrogen and water, the soil nitrogen was mineralized intensively

  13. Progress towards sugar beet improvement through somatic hybridization. Pt. 1. Inactivation of nuclei and cytoplasm in donor and recipient protoplasts

    International Nuclear Information System (INIS)

    The isolation and culture of suspension-derived protoplasts from two sugar beet (Beta vulgaris L.) genotypes are described. Immobilization of protoplasts in agarose resulted in high frequency divisions and microcallus regeneration, with plating efficiency (PE) being clearly genotype-dependent. In further studies towards asymmetric fusion experiments, the effect of different doses of ultraviolet radiation (UV) and iodoacetic acid (IA) on protoplast physiology was assessed. Viability of both treated (UV, IA) and untreated protoplasts (control) was determined by FDA staining, and the biological effect was evaluated by testing the ability of protoplasts to divide and to form calli. The results are discussed in terms of the applicability of the methods for the production of asymmetric protoplasts suitable for somatic hybridization within the genus Beta. (author)

    Full Text Available Description of the subject. Dietary fiber is largely used in pig production but some contradictions appear in the literature regarding the effects on performance and health. Objectives. This paper aims to contribute to the clarification of the effects of a diet rich in sugar beet pulp on animal behavior, growth performance, carcass quality and gut health of fattening pigs. Method. Two successive batches of 24 fattening pigs were each divided into two groups fed ad libitum either a standard diet based on cereals (STD, 19% NSP [non-starch-polysaccharides] or a fibrous diet based on 23% sugar beet pulp (HFD, 31% NSP. Results. Pigs activity rate and feeder occupancy duration were increased by 57% and 165% for group fed HFD, respectively (P < 0.05. The fecal bacteria counts showed increases with HFD for Lactobacillus (10.21 vs 9.84 log10 of cfu·g-1 of feces dry matter, P < 0.05 and Bifidobacterium (9.49 vs 8.88, P < 0.01 but decreases for Enterobacteriaceae (4.85 vs 5.97, P < 0.001. Reductions of the average daily gain (788 vs 876 g per day, P < 0.001 and the dressing percentage (75.7 vs 78.9%, P < 0.001 were observed with HFD. Gastric lesion score was decreased with HFD (0.82 vs 1.55, P < 0.05. For pigs fed HFD, the proportion of surface area occupied by goblet cells was increased in the jejunum (10.06 vs 7.99%, P < 0.01 and the number of CD3 lymphocytes was increased in the colon (1.24 vs 0.90·mm-², P < 0.05. Conclusions. HFD contributes to strengthen the gut health of fattening pigs, but it impairs growth performance and carcass traits.

    Full Text Available The aim of this study was to evaluate the pectinase activity of two commercial enzymes Rohament PL and Rohapect 10L, using as substrate the sugar beet pulp, in different conditions. The method applied to check the rate of hydrolysis was Fourier-transformed infrared spectroscopy (FT-MIR, by recording the absorption spectra of different carbohydrates in the specific, MIR (middle IR spectral range (650-4000 cm-1. In order to calibrate the method, it has been recorded the FT-MIR spectrum of standard solutions of glucose, fructose, sucrose and galacturonic acid, at different concentrations, establishing also the peaks and the fingerprint regions specific to these compounds. Considering the specific peak intensities identified for glucose (at 1033 cm-1, fructose (at 1063 cm-1, sucrose (at 995 cm-1, and based on peak area for galacturonic acid (1500-700 cm-1, it has been calculated their concentrations, as a result of the Rohament PL or Rohapect 10L activity. Based on calibration curves for each sugar type, it has been calculated their concentrations in the sugar beet samples, and after their release by enzymatic treatment, establishing an optimized protocol of action for the two enzymes. Differences among the two enzymes activity were identified, specifically their optimum concentration and hydrolysis timing. FT-MIR spectroscopy proves to be an adequate method to evaluate the enzymatic activity of the different enzyme types, having certain advantages in comparison with the chromatographic methods, being a rapid, non-destructive method, at relatively low costs.

  16. Further characterization of the red beet plasma membrane Ca sup 2+ -ATPase using GTP as an alternative substrate

    The GTP-driven component of Ca{sup 2+} uptake in red beet (Beta vulgaris L.) plasma membrane vesicles was further characterized to confirm its association with the plasma membrane Ca{sup 2+}-translocating ATPase and assess its utility as a probe for this transport system. Uptake of {sup 45}Ca{sup 2+} in the presence of GTP demonstrated similar properties to those previously observed for red beet plasma membrane vesicles utilizing ATP with respect to pH optimum sensitivity to orthovanadate, dependence on Mg:substrate concentration and dependence on Ca{sup 2+} concentration. Calcium uptake in the presence of GTP was also strongly inhibited by erythrosin B, a potent inhibitor of the plant plasma membrane Ca{sup 2+}-ATPase. Furthermore, after treatment with EGTA to remove endogenous calmodulin, the stimulation of {sup 45}Ca{sup 2+}-uptake by exogeneous calmodulin was nearly equivalent in the presence of either ATP or GTP. Taken together these results support the proposal that GTP-driven {sup 45}Ca{sup 2+} uptake represents the capacity of the plasma membrane Ca{sup 2+}-translocating ATPase to utilize this nucleoside triphosphate as an alternative substrate. When plasma membrane vesicles were phosphorylated with ({gamma}-{sup 32}P)GTP, a rapidly turning over, 100 kilodalton phosphorylated peptide was observed which contained an acyl-phosphate linkage. While it is proposed that this peptide could represent the catalytic subunit of the plasma membrane Ca{sup 2+}-ATPase, it is noted that this molecular weight is considerably lower than the 140 kilodalton size generally observed for plasma membrane Ca{sup 2+}-ATPases present in animal cells.

    The ethanolic extracts of red beet (Beta vulgaris L.) hairy root were used to investigate the removal of color and improvement of biological activity for enhanced industrial applications. The extracts were exposed to gamma rays ranging from 2.5 to 30 kGy. The red beet hairy root is composed of two major red-colorants, betanin and isobetanin. Gamma ray radiation at 5 kGy remarkably reduced the levels of the major colorants by 94% and the reddish color was eliminated by doses greater than 10 kGy. Color removal was likely due to the gamma ray radiolysis of ethanol. Although details on the mechanism responsible for the decay of the chromophore have not been entirely determined, our results suggest that the free radicals that are produced during this process are capable of destroying the chromophore group in isobetanin, thus bleaching the substrate solution. In spite of the degradation of the major colorants, the biological activities of constituents of the extract such as DPPH radical scavenging and tyrosinase inhibition were negligibly affected by the gamma ray radiation up to 20 kGy. The antioxidant activity was 92.7% in control samples and 90.0-92.0% in irradiated samples (2.5-20 kGy), and a slight decrease to 87.5% was observed for gamma ray radiation at 30 kGy. In addition, tyrosinase inhibition activity has also the same pattern; the activity is slightly increased from 50.7% of control to 49.1-52.8% of irradiated samples (2.5-20 kGy) with a 46.8% at 30 kGy.

  18. Nitrogen Nutrition of Sugar Beet as Affected by Water Salinity, Proline Acid and Nitrogen Forms Using 15N Tracer Technique

    International Nuclear Information System (INIS)

    A pot experiment was conducted under green house condition using sugar beet as a test crop. Saline water (sea water) was applied at different levels. i.e. fresh water, 4 and 8 dSm-1. Labelled urea and ammonium sulphate (5% a.e.) were applied at rate of 120 kg N fed-1. Also; proline amino acid was sprayed at rate of 25, and 50 ppm. Basal recommended doses of P and K were applied. Crop leaves and tuber yield were severely affected by sea water salinity. These parameters were improved by adding proline acid. Effect of proline acid was significantly varied according to rate of addition, water salinity levels and N forms. In this respect, the improvement of leaves and tuber was more pronounced at rate of 50 ppm proline under 8 dSm-1 salinity when plants fertilized with ammonium sulfate. Another picture was drawn with urea, where the improvement was detected at rate of 25 ppm proline, under 4dSm-1 water salinity level. Nitrogen, phosphorus, potassium and sodium uptake by leaves and tuber of sugar beet plants were significantly improved by addition of 50 ppm proline under 4 and /or 8 dSm-1 salinity levels. Nitrogen uptake was higher in tuber and fertilization with urea than those of leaves and ammonium sulfate, respectively. Other nutrients were varied according to N forms and proline levels. Nitrogen use efficiency was enhanced by spraying proline, despite of addition rates, and negatively affected by increasing salinity levels. In this regard, no big significant difference was detected between urea and ammonium sulfat

    Triterpene saponins are important bioactive constituents with an enormous variety in structure widely distributed in many plants. Here, we profiled triterpene saponins from the skin and flesh of red beetroot Beta vulgaris L. cultivars Nochowski from 2012 and 2013 season using reversed-phase liquid chromatography combined with negative-ion electrospray ionisation quadrupole mass spectrometry. We tentatively identified 44 triterpene saponins, of which 37 had not been detected previously in the root of red beets and 27 saponins were tentatively identified as potentially new compounds. All observed compounds were glycosides of four different aglycone structures, of which akebonoic acid and gypsogenin were not detected previous in red beetroot. Based on the high-resolution mass measurements among these 44 detected saponins 10 groups of isomers were identified. We report for the first time that 18 saponins with dioxolane-type (2 saponins) and acetal-type (16 saponins) substituents were detected in the roots of red beet. PMID:26304438

    The aim of this study was to examine the losses of methane forming potential during storage of pulpified sugar beets in open lagoons. A method was developed enabling the quantification of the losses without the need of a mass balance. For the use as substrate for biogas production, it has been proposed to pulpify sugar beets and to store this material in open ground basins (lagoons) which are lined with plastic film. The organic matter (OM) in the inner regions of the lagoon is preserved by anaerobic conditions and lactic acid fermentation. In the surface layer, which is exposed to the atmosphere, additional losses are generated by aerobic substrate degradation and evaporation of volatile compounds. (orig.)

    Leaf area index (LAI) and water content (WC) in the root zone are two major hydro-meteorological parameters that exhibit a dominant control on water, energy and carbon fluxes, and are therefore important for any regional eco-hydrological or climatological study. To investigate the potential for retrieving these parameter from hyperspectral remote sensing, we have investigated plant spectral reflectance (400–2,500 nm, ASD FieldSpec3) for two major agricultural crops (sugar beet and spring barl...

  10. Greenhouse gas emissions from first generation ethanol derived from wheat and sugar beet in Germany – Analysis and comparison of advanced by-product utilization pathways

    International Nuclear Information System (INIS)

    Highlights: ► Ethanol production from sugar beet and wheat is investigated. ► Instead of feed production from residues by-products are used for energy production. ► Ethanol from sugar beet with biogas co-production shows lowest GHG emissions. ► For wheat pathways bran and gluten separation generates lowest GHG emissions. ► An allocation method is recommended involving co-produced fertilizer. -- Abstract: In state of the art ethanol production, by-products like vinasse from sugar beet or distiller’s dried grains with solubles (DDGSs) from wheat grains are usually used as animal feed. The drying process consumes a significant amount of energy that could be reduced by producing other valuable materials or energy carriers from these by-products. Besides resulting higher overall conversion rates and improved process efficiencies, by-products, which can be extracted or are automatically created during the various conversion steps, should be used to reduce environmental impacts as well. In this analysis, advanced pathways for the recovery and use of by-products from bio-chemical ethanol production like gluten separation from wheat starch, biogas production from stillage or vinasse and combustion of bran for electricity generation are analyzed with regard to their contribution to the greenhouse effect. Therefore, different methodological approaches are applied and compared. The analysis shows among others that ethanol from sugar beet generates less greenhouse gases (GHGs) compared to the ethanol production from wheat. The biogas production from residues and especially the use of bran for heat and electricity generation shows significant GHG reduction compared to the state of the art application. However, the methodological approach for the treatment of by-products highly influences the results. For the reproducibility of the results an energy equivalent allocation method involving the specific application of the respective co-product is recommended.

  12. Use of agricultural waste sugar beet pulp for the removal of Gemazol turquoise blue-G reactive dye from aqueous solution

    International Nuclear Information System (INIS)

    The potential use of dried sugar beet pulp, an agricultural solid waste by-product, as an biosorbent for Gemazol turquoise blue-G, a copper-pthalocyanine reactive dye commonly used in dyeing of cotton, was investigated in the present study. Batch adsorption studies were carried out to examine the influence of various parameters such as initial pH, temperature and initial dye concentration. The results indicated that adsorption was strongly pH-dependent and slightly temperature-dependent. At 800 mg l-1 initial Gemazol turquoise blue-G concentration, dried sugar beet pulp exhibited the highest Gemazol turquoise blue-G uptake capacity of 234.8 mg g-1 at 25 deg. C and at an initial pH value of 2.0. The Freundlich, Langmuir, Redlich-Peterson and Langmuir-Freundlich, the two and three parameters adsorption models were used for the mathematical description of the biosorption equilibrium and isotherm constants were evaluated depending on temperature. Both the Langmuir and Redlich-Peterson models were applicable for describing the dye biosorption by dried sugar beet pulp in the concentration (100-800 mg l-1) and temperature (25-45 deg. C) ranges studied. Simple mass transfer and kinetic models were applied to the experimental data to examine the mechanisms of biosorption and potential rate controlling steps such as external mass transfer, intraparticle diffusion and biosorption process. The sorption process was found to be controlled by both surface and pore diffusion with surface diffusion at the earlier stages followed by pore diffusion at the later stages. Pseudo first-order, pseudo second-order and saturation type kinetic models described the biosorption kinetics accurately at all concentrations and temperatures studied. The thermodynamic analysis indicated that the sorption process was exothermic and the biosorption of dye on dried sugar beet pulp might be physical in nature

    2016-09-01

    A direct soil DNA extraction method from soil samples (250 g) was applied for detection of the soilborne sugar-beet-infecting pathogen Rhizoctonia solani anastomosis group (AG) 2-2IIIB using a newly developed real-time polymerase chain reaction assay that showed specificity to AG2-2IIIB when tested against various R. solani AG. The assay showed a good relation between cycle threshold and amount of AG2-2IIIB sclerotia detected in three spiked field soils and was also able to detect the pathogen in naturally infested field soil samples. A field trial was conducted to quantify R. solani AG2-2IIIB soil inoculum potential (IP) before and after growing a susceptible and a resistant sugar beet variety as well as after subsequent growth of an expected nonhost winter rye. Plants of the susceptible sugar beet variety displayed a higher disease severity. A more than sixfold increase of the R. solani AG2-2IIIB soil IP was observed in contrast to the resistant variety that resulted in a constant IP. Growing winter rye significantly reduced soil IP to the initial level at sowing. Further research is required to better understand the interaction between disease occurrence and soil IP as well as the environmental influence on IP development. PMID:27143412

  15. An environmental life cycle assessment comparing Australian sugarcane with US corn and UK sugar beet as producers of sugars for fermentation

    International Nuclear Information System (INIS)

    Sugarcane is a highly suitable substrate for the production of bio-products. As well as producing high yields of sugar, much of the plant's fibre is also recovered and used as a source of renewable energy. A life cycle assessment (LCA) of sugarcane production and processing in Australia was performed to develop an environmental profile of sugarcane as a source of bio-products. The application examined was fermentation products from sugar. The sugarcane results were compared with results for other sugar producing crops - US corn and UK sugar beet - to gauge its relative environmental performance. The results show sugarcane to have an advantage in respect of energy input, greenhouse gas emissions and possibly acidification potential due to its high saccharide yield and the displacement of fossil fuels with surplus renewable energy from cane fibre (bagasse). However Australian sugarcane can exhibit high nitrous oxide emissions, which would reduce greenhouse gas advantages in some regions. For eutrophication, sugar beet provides advantages due to the avoided production of other agricultural crops displaced by the use of beet pulp as an animal feed. The three factors found to have the most influence on the environmental impacts of these agro-industrial systems were the commodities displaced by by-products, agricultural yields, and nitrogen use efficiency.

    This study investigated the development of the microbial community during a long-term (337 days) anaerobic digestion of maize and sugar beet silage, two feedstocks that significantly differ in their chemical composition. For the characterization of the microbial dynamics, the community profiling method terminal restriction fragment length polymorphism (TRFLP) in combination with a cloning-sequencing approach was applied. Our results revealed a specific adaptation of the microbial community to the supplied feedstocks. Based on the high amount of complex compounds, the anaerobic conversion rate of maize silage was slightly lower compared with the sugar beet silage. It was demonstrated that members from the phylum Bacteroidetes are mainly involved in the degradation of low molecular weight substances such as sugar, ethanol and acetate, the main compounds of the sugar beet silage. It was further shown that species of the genus Methanosaeta are highly sensitive against sudden stress situations such as a strong decrease in the ammonium nitrogen (NH₄(+)-N) concentration or a drop of the pH value. In both cases, a functional compensation by members of the genera Methanoculleus and/or Methanosarcina was detected. However, the overall biomass conversion of both feedstocks proceeded efficiently as a steady state between acid production and consumption was recorded, which further resulted in an equal biogas yield.

  18. Gamma rays as an effective tool for removing undesirable color without adverse changes in biological activities of red beet extracts

    International Nuclear Information System (INIS)

    The ethanolic extracts of red beet (Beta vulgaris L.) hairy root were used to investigate the removal of color and improvement of biological activity for enhanced industrial applications. The extracts were exposed to gamma rays ranging from 2.5 to 30 kGy. The red beet hairy root is composed of two major red-colorants, betanin and isobetanin. Gamma ray radiation at 5 kGy remarkably reduced the levels of the major colorants by 94% and the reddish color was eliminated by doses greater than 10 kGy. Color removal was likely due to the gamma ray radiolysis of ethanol. Although details on the mechanism responsible for the decay of the chromophore have not been entirely determined, our results suggest that the free radicals that are produced during this process are capable of destroying the chromophore group in isobetanin, thus bleaching the substrate solution. In spite of the degradation of the major colorants, the biological activities of constituents of the extract such as DPPH radical scavenging and tyrosinase inhibition were negligibly affected by the gamma ray radiation up to 20 kGy. The antioxidant activity was 92.7% in control samples and 90.0–92.0% in irradiated samples (2.5–20 kGy), and a slight decrease to 87.5% was observed for gamma ray radiation at 30 kGy. In addition, tyrosinase inhibition activity has also the same pattern; the activity is slightly increased from 50.7% of control to 49.1–52.8% of irradiated samples (2.5–20 kGy) with a 46.8% at 30 kGy. - Highlights: ► Gamma ray radiation at 5 kGy remarkably reduced the levels of the major colorants. ► The reddish color was eliminated by doses greater than 10 kGy. ► The biological activities of constituents of the extract were negligibly affected by the gamma ray.

    Full Text Available Aim: This study was planned to investigate the effect of sugar beet, neem leaf, linseed and coriander on growth parameters such as feed intake, body weight gain, feed conversion ratio (FCR, performance index (PI, and carcass characteristics in broiler birds. Materials and Methods: The experiment was conducted for a period of 42 days on Vanaraja strain of broiler birds. Different dietary supplement such as sugar beet meal, neem leaf meal, linseed meal and coriander seed meal were used in the basal diet. All day-old 150 male chicks were individually weighed and distributed into five groups having 30 birds in each. Each group was further sub-divided into triplicates having 10 birds in each. Group T1served as control and rest groups T2, T3, T4 and T5 as treatment groups. Birds in T1 group were fed basal ration only, however, T2 , T3, T4 and T5 groups were fed basal ration mixed with 2.5% sugar beet meal, neem leaf meal, linseed meal, and coriander seed meal individually, respectively. Results: Broilers supplemented with herbs/spices showed improvement in growth attributes and carcass characteristics. Broilers fed with herbs at the rate of 2.5% had higher feed intake except sugar beet and coriander seed meal fed group. The body weight and weight gain was also significantly (p0.05 affected. Average giblet percentage of all supplemented groups were significantly (p<0.05 higher than control and was found to be highest in neem leaf meal fed group. Average by-product percentage was found to be highest in linseed fed group. Conclusion: Various herbs such as sugar beet, neem leaf, linseed and coriander seed meals affected the growth performance, and carcass trait showed positive inclination toward supplemented groups in broilers. The exact mode of action of these herbs/spices is still not clear, however, one or more numbers of active compounds present in these supplements may be responsible.

  20. Airborne and ground-based remote sensing for the estimation of evapotranspiration and yield of bean, potato, and sugar beet crops

    Jayanthi, Harikishan

    The focus of this research was two-fold: (1) extend the reflectance-based crop coefficient approach to non-grain (potato and sugar beet), and vegetable crops (bean), and (2) develop vegetation index (VI)-yield statistical models for potato and sugar beet crops using high-resolution aerial multispectral imagery. Extensive crop biophysical sampling (leaf area index and aboveground dry biomass sampling) and canopy reflectance measurements formed the backbone of developing of canopy reflectance-based crop coefficients for bean, potato, and sugar beet crops in this study. Reflectance-based crop coefficient equations were developed for the study crops cultivated in Kimberly, Idaho, and subsequently used in water availability simulations in the plant root zone during 1998 and 1999 seasons. The simulated soil water profiles were compared with independent measurements of actual soil water profiles in the crop root zone in selected fields. It is concluded that the canopy reflectance-based crop coefficient technique can be successfully extended to non-grain crops as well. While the traditional basal crop coefficients generally expect uniform growth in a region the reflectance-based crop coefficients represent the actual crop growth pattern (in less than ideal water availability conditions) in individual fields. Literature on crop canopy interactions with sunlight states that there is a definite correspondence between leaf area index progression in the season and the final yield. In case of crops like potato and sugar beet, the yield is influenced not only on how early and how quickly the crop establishes its canopy but also on how long the plant stands on the ground in a healthy state. The integrated area under the crop growth curve has shown excellent correlations with hand-dug samples of potato and sugar beet crops in this research. Soil adjusted vegetation index-yield models were developed, and validated using multispectral aerial imagery. Estimated yield images were

  1. Subcellular localization of the Triple Gene Block movement proteins of Beet necrotic yellow vein virus by electron microscopy

    International Nuclear Information System (INIS)

    The Triple Gene Block proteins TGBp1, TGBp2, and TGBp3 of Beet necrotic yellow vein virus (BNYVV) are required for efficient cell-to-cell spread of the infection. The TGB proteins can drive cell-to-cell movement of BNYVV in trans when expressed from a co-inoculated BNYVV RNA 3-based 'replicon'. TGBp2 and TGBp3 expressed from the replicon were nonfunctional in this assay if they were fused to the green fluorescent protein (GFP), but addition of a hemagglutinin (HA) tag to their C-termini did not incapacitate movement. Immunogold labeling of ultrathin sections treated with HA-specific antibodies localized TGBp2-HA and TGBp3-HA to what are probably structurally modified plasmodesmata (Pd) in infected cells. A similar subcellular localization was observed for TGBp1. Large gold-decorated membrane-rich bodies containing what appear to be short fragments of endoplasmic reticulum were observed near the cell periphery. The modified gold-decorated Pd and the membrane-rich bodies were not observed when the TGB proteins were produced individually in infections using the Tobacco mosaic virus P30 protein to drive cell-to-cell movement, indicating that these modifications are specific for TGB-mediated movement

  2. Molecular characterization and developmental expression of the gene encoding the prothoracicotropic hormone in the beet armyworm,Spodoptera exigua

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Prothoracicotropic hormone (PTTH), a neuropeptide hormone stimulating the prothoracic glands to synthesize ecdysone, plays an important role in regulating postembryonic development in insects. The cDNA encoding PTTH was isolated and sequenced from the beet armyworm, Spodoptera exigua (Spe). The deduced a?mino acid sequence is composed of a signal peptide, a peptide (65 amino acids) of un-known function, and a mature PTTH molecule (111 amino acids). The Spe-PTTH shows similarities (45.5%―70.3%) to other known PTTHs reported in Lepidoptera species, but 7 cysteine r?esidues and the hydrophobic regions were conserved. Whole-mount immunocytochemistry by using an antiserum against recombinant Helicoverpa armigera PTTH showed that Spe-PTTH was synthesized in two pairs of neurosecretory cells in the S. exigua brain. Northern blot analysis demonstrates the presence of a 1.2-kb transcript in the brain. The Spe-PTTH mRNA is detectable at high levels at the wandering larval stage, early pupal stage, and pharate adult stage, suggesting that the Spe-PTTH gene might be corre-lated with molting, metamorphosis, and reproduction.

    Full Text Available Abstract Background Plasmodiophorids and chytrids are zoosporic parasites of algae and land plant and are distributed worldwide. There are 35 species belonging to the order Plasmodiophorales and three species, Polymyxa betae, P. graminis, and Spongospora subterranea, are plant viral vectors. Plasmodiophorid transmitted viruses are positive strand RNA viruses belonging to five genera. Beet necrotic yellow vein virus (BNYVV and its vector, P. betae, are the causal agents for rhizomania. Results Evidence of BNYVV replication and movement proteins associating with P. betae resting spores was initially obtained using immunofluorescence labeling and well characterized antisera to each of the BNYVV proteins. Root cross sections were further examined using immunogold labeling and electron microscopy. BNYVV proteins translated from each of the four genomic and subgenomic RNAs accumulate inside P. betae resting spores and zoospores. Statistical analysis was used to determine if immunolabelling detected viral proteins in specific subcellular domains and at a level greater than in control samples. Conclusion Virus-like particles were detected in zoosporangia. Association of BNYVV replication and movement proteins with sporangial and sporogenic stages of P. betae suggest that BNYVV resides inside its vector during more than one life cycle stage. These data suggest that P. betae might be a host as well as a vector for BNYVV

Sugar yield components were considered as the first order variables (FOV in previous path analyses studies, while white sugar yield (WSY and its related traits were the FOV here. Three lines of sugar beet (7219-P.69, BP-Karaj, 7112 were evaluated in drought and non-drought conditions. Two sequential path models were used for analysis of associations among WSY and its related traits by arraying the various variables in first-, second-, and third-order paths on the basis of their maximum direct effects and minimal collinearity. Four first-order variables, namely root diameter, sugar yield, molasses content and sugar content, revealed highest direct effects on WSY at normal condition, while root length, α-amino-N, root yield, crown dry weight, water use efficiency and Na+ were found to fit as second-order variables. Three first-order variables, namely sugar content, sugar yield and molasses content, revealed highest direct effects on white sugar yield at drought-stress condition. In this case, sugar yield had the highest direct effect on WSY. In general, the sequential path analysis was efficiently demonstrated the effects of predictor variables.

    Full Text Available Influence of herbicides on the hydrogen peroxide generation in vacuolar extracts of red beet root (Beta vulgaris L. was investigated. Belonging to different chemical classes of herbicide compounds have been used. Herbicides differ from each other in the mechanism of effects on plants. Clopyralid (aromatic acid herbicide, derivative of picolinic acid and 2.4-D (phenoxyacetic herbicide, characterized by hormone-like effects, contributed to the formation of H2O2 in vacuolar extracts. Fluorodifen (nitrophenyl ether herbicide and diuron (urea herbicide also have increased contents H2O2. These compounds inhibit the electron transport, photosynthesis, and photorespiration in sensitive plants. Herbicidal effect of glyphosate (organophosphorus herbicide is due to the inhibition of amino acid synthesis in plant cells. Glyphosate did not affect the content of H2O2 in vacuolar extracts. Herbicide dependent H2O2-generation did not occur with oxidoreductase inhibitors, potassium cyanide and sodium azide. The results suggest that the formation of ROS in the vacuoles due to activity of oxidoreductases, which could interact with herbicides.

    A low pH, ethanol-type fermentation process was evaluated for wastewater treatment and bio-hydrogen production from acidic beet sugar factory wastewater in a continuous stirred tank reactor (CSTR) with an effective volume of 9.6 L by anaerobic mixed cultures in this present study. After inoculating with aerobic activated sludge and operating at organic loading rate (OLR) of 12 kgCOD·m-3·d-1, HRT of 8h, and temperature of 35℃ for 28 days, the CSTR achieved stable ethanol-type fermentation. When OLR was further increased to 18 kgCOD·m-3·d-1, on the 53rd day, ethanol-type fermentation dominant microflora was enhanced. The liquid fermentation products, including volatile fatty acids (VFAs) and ethanol, stabilized at 1493mg·L-1 in the bioreactor. Effluent pH, oxidation-reduction potential (ORP), and alkalinity ranged at 4.1-4.5, -250-(-290) mV, and 230-260mgCaCO3·L-1. The specific hydrogen production rate of anaerobic activated sludge was 0.1 L'gMLVSS-1· d-1 and the COD removal efficiency was 45%. The experimental results showed that the CSTR system had good operation stability and microbial activity, which led to high substrate conversion rate and hydrogen production ability.

    The α-glucosidase from sugar beet (SBG) is an exo-type glycosidase. The enzyme has a pocket-shaped active site, but efficiently hydrolyzes longer maltooligosaccharides and soluble starch due to lower Km and higher kcat/Km for such substrates. To obtain structural insights into the mechanism governing its unique substrate specificity, a series of acarviosyl-maltooligosaccharides was employed for steady-state kinetic and structural analyses. The acarviosyl-maltooligosaccharides have a longer maltooligosaccharide moiety compared with the maltose moiety of acarbose, which is known to be the transition state analog of α-glycosidases. The clear correlation obtained between log Ki of the acarviosyl-maltooligosaccharides and log(Km/kcat) for hydrolysis of maltooligosaccharides suggests that the acarviosyl-maltooligosaccharides are transition state mimics. The crystal structure of the enzyme bound with acarviosyl-maltohexaose reveals that substrate binding at a distance from the active site is maintained largely by van der Waals interactions, with the four glucose residues at the reducing terminus of acarviosyl-maltohexaose retaining a left-handed single-helical conformation, as also observed in cycloamyloses and single helical V-amyloses. The kinetic behavior and structural features suggest that the subsite structure suitable for the stable conformation of amylose lowers the Km for long-chain substrates, which in turn is responsible for higher specificity of the longer substrates.

    Association mapping has become a widely applied genomic approach to dissect the genetic architecture of complex traits. A major issue for association mapping is the need to control for the confounding effects of population structure, which is commonly done by mixed models incorporating kinship information. In this case study, we employed experimental data from a large sugar beet population to evaluate multi-locus models for association mapping. As in linkage mapping, markers are selected as cofactors to control for population structure and genetic background variation. We compared different biometric models with regard to important quantitative trait locus (QTL) mapping parameters like the false-positive rate, the QTL detection power and the predictive power for the proportion of explained genotypic variance. Employing different approaches we show that the multi-locus model, that is, incorporating cofactors, outperforms the other models, including the mixed model used as a reference model. Thus, multi-locus models are an attractive alternative for association mapping to efficiently detect QTL for knowledge-based breeding. PMID:25351864

    Numerous observations indicate a high flexibility of microbial communities in different biogas reactors during anaerobic digestion. Here, we describe the functional redundancy and structural changes of involved microbial communities in four lab-scale continuously stirred tank reactors (CSTRs, 39°C, 12 L volume) supplied with different mixtures of maize silage (MS) and sugar beet silage (SBS) over 80 days. Continuously stirred tank reactors were fed with mixtures of MS and SBS in volatile solid ratios of 1:0 (Continuous Fermenter (CF) 1), 6:1 (CF2), 3:1 (CF3), 1:3 (CF4) with equal organic loading rates (OLR 1.25 kgVS m(-3)  d(-1) ) and showed similar biogas production rates in all reactors. The compositions of bacterial and archaeal communities were analysed by 454 amplicon sequencing approach based on 16S rRNA genes. Both bacterial and archaeal communities shifted with increasing amounts of SBS. Especially pronounced were changes in the archaeal composition towards Methanosarcina with increasing proportion of SBS, while Methanosaeta declined simultaneously. Compositional shifts within the microbial communities did not influence the respective biogas production rates indicating that these communities adapted to environmental conditions induced by different feedstock mixtures. The diverse microbial communities optimized their metabolism in a way that ensured efficient biogas production. PMID:26200922

    Short interspersed nuclear elements (SINEs) are non-autonomous non-long terminal repeat retrotransposons which are widely distributed in eukaryotic organisms. While SINEs have been intensively studied in animals, only limited information is available about plant SINEs. We analysed 22 SINE families from seven genomes of the Amaranthaceae family and identified 34 806 SINEs, including 19 549 full-length copies. With the focus on sugar beet (Beta vulgaris), we performed a comparative analysis of the diversity, genomic and chromosomal organization and the methylation of SINEs to provide a detailed insight into the evolution and age of Amaranthaceae SINEs. The lengths of consensus sequences of SINEs range from 113 nucleotides (nt) up to 224 nt. The SINEs show dispersed distribution on all chromosomes but were found with higher incidence in subterminal euchromatic chromosome regions. The methylation of SINEs is increased compared with their flanking regions, and the strongest effect is visible for cytosines in the CHH context, indicating an involvement of asymmetric methylation in the silencing of SINEs.

    Bioethanol production generates large amounts of vinasse, which is suitable for biogas production. In this study, the anaerobic digestion of sugar beet vinasse was optimised using continuous stirred-tank reactors (CSTR) supplemented either with lime fertiliser or with 3% cow manure. In both reactors, the C/N ratio was adjusted by adding straw. The biochemical methane potential (BMP) of vinasse was 267.4±4.5LCH4kgVS(-1). Due to the low content of macro- and micronutrients and low C/N ratio of vinasse, biogas production failed when vinasse alone was fed to the reactor. When co-substrate was added, biogas production achieved very close to the BMP of vinasse, being 235.7±32.2LCH4kgVS(-1) from the fertiliser supplied reactor and 265.2±26.8LCH4kgVS(-1) in manure supplied reactor at steady state. Anaerobic digestion was the most stable when cow manure was supplied to digestion of vinasse. PMID:25958146

    Prothoracicotropic hormone (PTTH), a neuropeptide hormone stimulating the prothoracic glands to synthesize ecdysone, plays an important role in regulating postembryonic development in insects. The cDNA encoding PTTH was isolated and sequenced from the beet armyworm, Spodoptera exigua (Spe).The deduced amino acid sequence is composed of a signal peptide, a peptide (65 amino acids) of unknown function, and a mature PTTH molecule (111 amino acids). The Spe-PTTH shows similarities(45.5%-70.3%) to other known PTTHs reported in Lepidoptera species, but 7 cysteine residues and the hydrophobic regions were conserved. Whole-mount immunocytochemistry by using an antiserum against recombinant Helicoverpa armigera PTTH showed that Spe-PTTH was synthesized in two pairs of neurosecretory cells in the S. exigua brain. Northern blot analysis demonstrates the presence of a 1.2-kb transcript in the brain. The Spe-PTTH mRNA is detectable at high levels at the wandering larval stage, early pupal stage, and pharate adult stage, suggesting that the Spe-PTTH gene might be correlated with molting, metamorphosis, and reproduction.

    physical, physicochemical properties of soils, its air, water and thermal rate. Humic acids with mineral and organomineral particles of soil form the soil absorbent complex. The inclusion of humic fertilizers promotes the process when humic substances form a very valuable water-stable clumpy-granular structure, which improves water-carrying and water-holding capacity, its air permeability by agglutination of mineral particles with each other. The soils, where humic fertilizers are carried in soils regularly, are more stable for influence of chemical polluting substances (for example, radioactive nuclides, heavy metals, pesticides) than poor soils. The inclusion of humic fertilizers is very important in period of urbanization and cropping on the plough-lands not far from a big industrial area. The lignitic materials tie together the detrimental compounds formed the insoluble complex in soil solution. The detrimental compounds don't go into plants, subsoil waters and atmosphere. The lignitic watering of soils (in concentration from 0.1 to 0.01%) increases biological activity of soil in a man-caused zones and it promotes to stability of plants to detrimental emission of enterprises. Today the problem of processing of sugar-beet industry is very important. In the result of storing sugar-beet wastes the pollution of environment is occurred, examples of this pollution are gassing, salinization of soils and ground waters by filtrational sediments. One of these wastes is defecation sludge. The defecation sludge consists of CaCO3, organic matter, nitrogen, phosphorus, potassium and microelements. The technology of receiving N-Ca fertilizer based on defecate was developed because of impossibility of using this waste in pure form. For available data, using of these fertilizers improves the soil fertility and degree of pollution by heavy metals don't exceed an acceptance limits.

    The highest PG activity was obtained in beet pulp with (NH4)2HPO4 in amount equivalent to 0.14--0.28% N after 7 days of growth; At optimal concentration, (NH4)2HPO4 did not influence the biomass production, but increased the pH of the culture media to above 6.0. The PG was an extracellular enzyme, acting mainly on highly esterified pectin. The attack was of a random manner, characteristic for the endo-enzymes. The enzyme was active at temperature 20 degrees C--40 degrees C and pH 5.0--6.0. PMID:81597
