Full Text Available Introduction Ensiling is one of the common preserving methods for forage or other organic materials. In this method, organic matters were preserved by proving an aerobic condition and then by reducing the pH with increasing acids production (mainly lactic acid. Some circumstances like enough soluble carbohydrates, low buffering capacity and appropriate dry matter concentration are needed in ensilages for an ideal silage production. Seepage production during ensiling is one of the most problems especially when high moisture materials (like fresh beet sugar pulp are ensiled. Silage seepage can pollute the environment and make loses in nutrients like soluble carbohydrates, protein, organic acids and etc. Moreover, lactic acid bacteria inoculants (Mainly consist of Lactobacillus plantarum have been widely used for improving fermentation pattern in ensilages. These external provided bacteria usually enhance lactic acid production in silage and then accelerate the falling of pH values in silages. Rapid decrease in pH can inhibit non-beneficial bacteria from activity which finally preserves nutrients from un-necessary fermentation or oxidation. The aim of this study was to investigate the interactive effects of lactic acid bacteria inoculants and some absorbents (straw and pith on chemical properties and fermentation profile of wet sugar beet pulp silage. Materials and Methods In the first experiment, fresh wet sugar beet pulp was treated with 5% straw or 5% pith in order to investigate the effects of these absorbents on chemical composition, fermentation characteristics and effluent production during ensiling period. In the second experiment, fresh wet sugar beet pulp was treated with a commercial lactic acid bacteria inoculants (Ecosyle and/or 5% pith in order to investing the main and interaction effects of the bacterial bacteria inoculants and the best absorbents from the experiment 1. In both experiments, triplicate samples were prepared for each

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. Copyright © 2015 Elsevier Ltd. All rights reserved.

This current work is concerned with the modification of sugar beet pulp (SBP) pectin assisted by pulsed electric filed (PEF) without solvent. Pectin-arachates with degree of esterification (DE) ranging from 49 to 84 were prepared in one-step modification. The results showed that the DE of pectin derivatives increased significantly with the PEF intensity from 18 to 30 kV cm((1) and total specific energy input from 124 to 345 J mL((1). Evidence of modification of pectin was provided by FT-IR, X-ray diffraction patterns and NMR spectra. Thermogravimetric investigation of modified pectin indicated a higher thermal stability than the untreated one. Results revealed that PEF technology is a promising method for industrial manufacture of pectin derivatives. Copyright © 2012 Elsevier Ltd. All rights reserved.

Sulfurous acid was used for pretreatment of sugar beet pulp (SBP) in order to achieve high efficiency of both extraction of carbohydrates and subsequent enzymatic hydrolysis of the remaining solids. The main advantage of sulfurous acid usage as pretreatment agent is the possibility of its regeneration. Application of sulfurous acid as hydrolyzing agent in relatively low concentrations (0.6-1.0 %) during a short period of time (10-20 min) and low solid to liquid ratio (1:3, 1:6) allowed effective extraction of carbohydrates from SBP and provided positive effect on subsequent enzymatic hydrolysis. The highest obtained concentration of reducing substances (RS) in hydrolysates was 8.5 %; up to 33.6 % of all carbohydrates present in SBP could be extracted. The major obtained monosaccharides were arabinose and glucose (9.4 and 7.3 g/l, respectively). Pretreatment of SBP with sulfurous acid increased 4.6 times the yield of glucose during subsequent enzymatic hydrolysis of remaining solids with cellulase cocktail, as compared to the untreated SBP. Total yield of glucose during SBP pretreatment and subsequent enzymatic hydrolysis amounted to 89.4 % of the theoretical yield. The approach can be applied directly to the wet SBP. Hydrolysis of sugar beet pulp with sulfurous acid is recommended for obtaining of individual monosaccharides, as well as nutritional media.

The objective of this study was to determine the effect of different sugar beet pulp (SBP) pretreatments on biogas yield from anaerobic digestion. SBP was subjected to grinding, thermal-pressure processing, enzymatic hydrolysis, or combination of these pretreatments. It was observed that grinding of SBP to 2.5-mm particles resulted in the cumulative biogas productivity of 617.2 mL/g volatile solids (VS), which was 20.2 % higher compared to the biogas yield from the not pretreated SBP, and comparable to that from not ground, enzymatically hydrolyzed SBP. The highest cumulative biogas productivity, 898.7 mL/g VS, was obtained from the ground, thermal-pressure pretreated and enzymatically hydrolyzed SBP. The latter pretreatment variant enabled to achieve the highest glucose concentration (24.765 mg/mL) in the enzymatic hydrolysates. The analysis of energy balance showed that the increase in the number of SBP pretreatment operations significantly reduced the gain of electric energy.

The lignocellulolytic fungus, Penicillium purpurogenum, grows on a variety of natural carbon sources, among them sugar beet pulp. Culture supernatants of P. purpurogenum grown on sugar beet pulp were partially purified and the fractions obtained analyzed for esterase activity by zymograms. The bands with activity on methyl umbelliferyl acetate were subjected to mass spectrometry to identify peptides. The peptides obtained were probed against the proteins deduced from the genome sequence of P. purpurogenum. Eight putative esterases thus identified were chosen for future work. Their cDNAs were expressed in Pichia pastoris. The supernatants of the recombinant clones were assayed for esterase activity, and five of the proteins were active against one or more substrates: methyl umbelliferyl acetate, indoxyl acetate, methyl esterified pectin and fluorescein diacetate. Three of those enzymes were purified, further characterized and subjected to a BLAST search. Based on their amino acid sequence and properties, they were identified as follows: RAE1, pectin acetyl esterase (CAZy family CE 12); FAEA, feruloyl esterase (could not be assigned to a CAZy family) and EAN, acetyl esterase (former CAZy family CE 10).

The factor which determines the economy in the EtOH industry which uses sugar beets as raw materials is the rapid and complete recovery of the sugar contained in the beets for fermentation purposes. It is best to extract the beets at 70 to 75/sup 0/. Thorough shredding of the beets then need no longer form part of the operation, and the protein compounds, which give rise to fuel oils, are extracted in small amounts only.

Over 8 million tonnes of sugar beet are grown annually in the UK. Sugar beet pulp (SBP) is the main by-product of sugar beet processing which is currently dried and sold as a low value animal feed. SBP is a rich source of carbohydrates, mainly in the form of cellulose and pectin, including d-glucose (Glu), l-arabinose (Ara) and d-galacturonic acid (GalAc). This work describes the technical feasibility of an integrated biorefinery concept for the fractionation of SBP and conversion of these monosaccharides into value-added products. SBP fractionation is initially carried out by steam explosion under mild conditions to yield soluble pectin and insoluble cellulose fractions. The cellulose is readily hydrolysed by cellulases to release Glu that can then be fermented by a commercial yeast strain to produce bioethanol at a high yield. The pectin fraction can be either fully hydrolysed, using physico-chemical methods, or selectively hydrolysed, using cloned arabinases and galacturonases, to yield Ara-rich and GalAc-rich streams. These monomers can be separated using either Centrifugal Partition Chromatography (CPC) or ultrafiltration into streams suitable for subsequent enzymatic upgrading. Building on our previous experience with transketolase (TK) and transaminase (TAm) enzymes, the conversion of Ara and GalAc into higher value products was explored. In particular the conversion of Ara into l-gluco-heptulose (GluHep), that has potential therapeutic applications in hypoglycaemia and cancer, using a mutant TK is described. Preliminary studies with TAm also suggest GluHep can be selectively aminated to the corresponding chiral aminopolyol. The current work is addressing the upgrading of the remaining SBP monomer, GalAc, and the modelling of the biorefinery concept to enable economic and Life Cycle Analysis (LCA).

The aim of this work was to demonstrate the feasibility of the application of biosorption in the treatment of metal polluted wastewaters through the development of several pilot plants to be implemented by the industry. The use as biosorbents of both the brown seaweed Fucus vesiculosus and a sugar beet pulp was investigated to remove heavy metal ions from a wastewater generated in an electroplating industry: Industrial Goñabe (Valladolid, Spain). Batch experiments were performed to study the effects of pH, contact time and initial metal concentration on metal biosorption. It was observed that the adsorption capacity of the biosorbents strongly depended on the pH, increasing as the pH rises from 2 to 5. The adsorption kinetic was studied using three models: pseudo first order, pseudo second order and Elovich models. The experimental data were fitted to Langmuir and Freundlich isotherm models and the brown alga F. vesiculosus showed higher metal uptake than the sugar beet pulp. The biomasses were also used for zinc removal in fixed-bed columns. The performance of the system was evaluated in different experimental conditions. The mixture of the two biomasses, the use of serial columns and the inverse flow can be interesting attempts to improve the biosorption process for large-scale applications.

Full Text Available Summary. Priority social problem in the Russian Federation is to provide diverse populations rational healthy diet, taking into account their traditions and economic status. Solving this problem requires the development of processing industries of agriculture on the basis of the improvement of existing and creation of new energy-saving environmentally friendly technologies that can provide deep, if possible without waste, recycling of raw materials. Therefore, the aim of research was the development of technology for production of sugar beet chips. Technology is as follows: sugar beet supplied into the washing machine to remove dirt from its surface. Washed roots inspect on conveyor belts. Next pure sugar beets sent to steam-heat treatment for cleaning the skin. After the beets is subjected to cutting by combining this process with a treatment with an aqueous solution of citric acid. Then he sent for the drying process is completed upon reaching a product of moisture content of 4-5 %. Drying chips feature is that under the high temperature reaction proceeds melanoidins between proteins and sugars present in sugar beet. As a result, the product obtained has the following characteristics: gold-yellow color; absence of a characteristic odor of sugar beet; pleasant sour taste; humidity of 4-5%. Thus, the new technology is relevant, because now the chips are one of the most popular products, ready to eat. A beet chips are rich in dietary fiber (pectin, hemicellulose and cellulose - 4-5 % minerals - macroelements (potassium, sodium, magnesium, calcium, phosphorus, trace elements (iron, zinc, copper, manganese - 0.5-0.6 %, and are the product of a functional food.

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 We considered a new technology for processing sugar beet into intermediate product for the food industry. Nowadays sugar beet is mainly used for processing into granulated sugar. In the granulated sugar obtaining sugar beet undergoes deep extraction of all nutrients: proteins, minerals, pectin, organic acids, preventing the crystallization process, and then the refined product (granulated sugar with a mass fraction of sucrose not less than 99.75% is obtained. We developed a technology for producing a sugar beet paste, which allows to preserve both sucrose, and almost all useful for human food substances containing in beet. A sugar beet paste is a valuable food product. Carbohydrates, organic acids, minerals, proteins, dietary fibers and vitamins are found in it. The block diagram of a sugar beet paste is given in the article. Technology of obtaining a sugar beet paste was tested under production conditions at the cannery (Joint Stock Company "Sadovoye" Liskinsky district,. Storozhevoe village, Voronezh region. The chemical composition of the paste (Dry Substances = 40% was determined, the degree of meeting of daily requirement for nutrients was calculated. 100 g of the product satisfy the daily requirement for dietary fiber by 42.5%, organic acids by 27.5% potassium by 24.0%, magnesium by 40.0%, iron by 26.7%. The sugar beet paste can be used as a semi-finished product in the confectionery, bakery, food concentrates industry, for products with increased nutritional value, as well as the finished product instead of marmalade and jam.

2015-09-11

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.

2008-01-01

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

Besides the widely discussed negative environmental effects of dairy production, such as greenhouse gas emissions, the feeding of large amounts of potentially human-edible feedstuffs to dairy cows is another important sustainability concern. The aim of this study was therefore to investigate the effects of a complete substitution of common cereal grains and pulses with a mixture of wheat bran and sugar beet pulp in a high-forage diet on cow performance, production efficiency, feed intake, and ruminating behavior, as well as on net food production potential. Thirteen multiparous and 7 primiparous mid-lactation Holstein dairy cows were randomly assigned to 1 of 2 treatments in a change-over design with 7-wk periods. Cows were fed a high-forage diet (grass silage and hay accounted for 75% of the dry matter intake), supplemented with either a cereal grain-based concentrate mixture (CON), or a mixture of wheat bran and dried sugar beet pulp (WBBP). Human-edible inputs were calculated for 2 different scenarios based on minimum and maximum potential recovery rates of human-edible energy and protein from the respective feedstuffs. Dietary starch and neutral detergent fiber contents were 3.0 and 44.1% for WBBP, compared with 10.8 and 38.2% in CON, respectively. Dietary treatment did not affect milk production, milk composition, feed intake, or total chewing activity. However, chewing index expressed in minutes per kilogram of neutral detergent fiber ingested was 12% lower in WBBP compared with CON. In comparison to CON, the human-edible feed conversion efficiencies for energy and protein, defined as human-edible output per human-edible input, were 6.8 and 5.3 times higher, respectively, in WBBP under the maximum scenario. For the maximum scenario, the daily net food production (human-edible output minus human-edible input) increased from 5.4 MJ and 250 g of crude protein per cow in CON to 61.5 MJ and 630 g of crude protein in the WBBP diet. In conclusion, our data suggest

Full Text Available Summary. Sugar beet is one of the strategic crops for food safety of Russia. The lack of specialized warehouse for harvest does not provide storage of roots for a long time. In the case of a thaw roots that have been defrosted unsuitable for processing. Beet and products of its processing is a good object for the development of microorganisms. Permanent microflora of sugar production are: Bacillus subtilis, Clostridium perfringes, Leuconostoc dextranicum, Torula alba, Pseudomonas fluorescens, Sarcina lutea and other kinds of microorganisms, leading to a problem processing of beet root and reduced quality of sugar. The most dangerous is the slimy bacteriosis is a bacterial disease beet caused by heterofermentative cocci of Leuconostoc (Leuconostoc mesenteroides, L. dextranicum. Product of the vital activity of microorganisms is dextran, which is synthesized from sucrose as a result of dextrany or mucous fermentation and leads to significant technological problems in processing of infected beet. Improving the efficiency of sugar production is connected with decrease in loss of quality of raw material preparation, storing and processing of sugar beet. At sugar plants use a variety of drugs that suppress the growth of pathogenic microflora, but there comes a rapid adaptation of microorganisms, therefore there is a need to implement new products to prevent damage to roots and improve the quality of produced sugar. To resolve this problem experimentally selected bactericidal drug, defined its rational concentration and conditions for the use in sugar beet production. The use of antibacterial drug in the process of extraction allows to increase the purity of diffusion juice 1.3 %, reduce the protein content in it (12.5 %; with the purity of the pure juice increases by 1.1 %, its color index is reduced by 44.7 %.

Full Text Available From 2008 to 2010 the levels of sugar beet seedlings infection caused by Rhizoctonia solani were compared in laboratory tests. Seven sugar beet lines were tested: H56, H66, S2, S3, S4, S5 and S6 as well as three control cultivars: Carlos, Esperanza and Janosik. Sugar beet lines with tolerance to rhizoctoniosis and cultivars without tolerance were infected artificially by R. solani isolates: R1, R28a and R28b. These isolates belong to the second anastomosis group (AG, which is usually highly pathogenic to beet roots. The aim of the experiment was to test whether the tolerance of sugar beet genotypes to R. solani AG 2 prevents both root rot, and damping-off of seedlings, induced by the pathogen. Sugar beet lines tolerant to brown root rot in laboratory tests were significantly less sensitive to infection of the seedlings by R. solani AG 2 isolates in comparison to control cultivars. Rhizoctonia solani AG 2 isolates demonstrated considerable differences in pathogenicity against seedlings of sugar beet lines and cultivars. The strongest infection of sugar beet seedlings occurred with the isolate R28b. The greatest tolerance to infection by AG 2 isolates was found for the S5 and S3 breeding lines.

The objective of this paper was to apply terahertz (THz) spectroscopy combined with chemometrics techniques for discrimination of genetically modified (GM) and non-GM sugar beets. In this paper, the THz spectra of 84 sugar beet samples (36 GM sugar beets and 48 non-GM ones) were obtained by using terahertz time-domain spectroscopy (THz-TDS) system in the frequency range from 0.2 to 1.2 THz. Three chemometrics methods, principal component analysis (PCA), discriminant analysis (DA) and discriminant partial least squares (DPLS), were employed to classify sugar beet samples into two groups: genetically modified organisms (GMOs) and non-GMOs. The DPLS method yielded the best classification result, and the percentages of successful classification for GM and non-GM sugar beets were both 100%. Results of the present study demonstrate the usefulness of THz spectroscopy together with chemometrics methods as a powerful tool to distinguish GM and non-GM sugar beets.

2016-10-01

Full Text Available Research into fermentative production of lactic acid from agricultural by-products has recently concentrated on the direct conversion of biomass, whereby pure sugars are replaced with inexpensive feedstock in the process of lactic acid production. In our studies, for the first time, the source of carbon used is sugar beet pulp, generated as a by-product of industrial sugar production. In this paper, we focus on the simultaneous saccharification of lignocellulosic biomass and fermentation of lactic acid, using mixed cultures with complementary assimilation profiles. Lactic acid is one of the primary platform chemicals, and can be used to synthesize a wide variety of useful products, including green propylene glycol. A series of controlled batch fermentations was conducted under various conditions, including pretreatment with enzymatic hydrolysis. Inoculation was performed in two sequential stages, to avoid carbon catabolite repression. Biologically-synthesized lactic acid was catalytically reduced to propylene glycol over 5% Ru/C. The highest lactic acid yield was obtained with mixed cultures. The yield of propylene glycol from the biological lactic acid was similar to that obtained with a water solution of pure lactic acid. Our results show that simultaneous saccharification and fermentation enables generation of lactic acid, suitable for further chemical transformations, from agricultural residues.

Homogalacturonan-derived partly methylated and/or acetylated oligogalacturonates were recovered after enzymatic hydrolysis (endo-polygalacturonase+pectin methyl esterase+side-chain degrading enzymes) of sugar beet pectin followed by anion-exchange and size exclusion chromatography. Around 90% of the GalA and 75% of the acetyl groups present in the initial sugar beet pectin were recovered as homogalacturonan-derived oligogalacturonates, the remaining GalA and acetyl belonging to rhamnogalacturonic regions. Around 50% of the acetyl groups present in sugar beet homogalacturonans were recovered as partly methylated and/or acetylated oligogalacturonates of degree of polymerisation 5 whose structures were determined by electrospray ionization ion trap mass spectrometry (ESI-IT-MSn). 2-O-acetyl- and 3-O-acetyl-GalA were detected in roughly similar amounts but 2,3-di-O-acetylation was absent. Methyl-esterified GalA residues occurred mainly upstream 2-O-acetyl GalA. Oligogalacturonates containing GalA residues that are at once methyl- and acetyl-esterified were recovered in very limited amounts. A tentative mapping of the distribution of acetyl and methyl esters within sugar beet homogalacturonans is proposed. Unsubstituted GalA residues are likely to be present in limited amounts (approximately 10% of total GalA residues), due to the fact that methyl and acetyl groups are assumed to be most often not carried by the same residues.

Feasibility of converting a sugar beet plant to fuel ethanol production

Energy Technology Data Exchange (ETDEWEB)

Hammaker, G S; Pfost, H B; David, M L; Marino, M L

1981-04-01

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)

Molassed sugar beet pulp (Bp) is a viable alternative to grains in cattle nutrition for reducing human edible energy input. Yet little is known about the effects of high inclusion rates of Bp on rumen microbiota. This study used an in vitro approach and the quantitative polymerase chain reaction technique to establish the effects of a graded replacement of maize grain (MG) by Bp on the ruminal microbial community, fermentation profile and nutrient degradation. Six different amounts of Bp (0-400 g kg -1 ), which replaced MG in the diet, were tested using the in vitro semi-continuous rumen simulation technique. The increased inclusion of Bp resulted in greater dietary content and degradation of neutral detergent fibre (P fermentation. However, high replacement rates of Bp resulted in lowered utilization of ammonia and higher ruminal methane production. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Autio, Sari; Siimes, Katri; Laitinen, Pirkko; Rämö, Sari; Oinonen, Seija; Eronen, Liisa

2004-04-01

Three sugar beet herbicides, ethofumesate, phenmedipham and metamitron, are currently used on conventional sugar beet cultivation, while new varieties of herbicide resistant (HR) sugar beet, tolerant of glyphosate or glufosinate-ammonium, are under field testing in Finland. Little knowledge has so far been available on the adsorption of these herbicides to Finnish soils. The adsorption of these five herbicides was studied using the batch equilibrium method in 21 soil samples collected from different depths. Soil properties like organic carbon content, texture, pH and partly the phosphorus and oxide content of the soils were tested against the adsorption coefficients of the herbicides. In general, the herbicides studied could be arranged according to their adsorption coefficients as follows: glyphosate>phenmedipham>ethofumesate approximately glufosinate-ammonium>metamitron, metamitron meaning the highest risk of leaching. None of the measured soil parameters could alone explain the adsorption mechanism of these five herbicides. The results can be used in model assessments of risk for leaching to ground water resulting from weed control of sugar beet in Finland.

The choice of rational parameters of beet pulp drying process in a pulsed low-pressure vibro-boiling layer

Directory of Open Access Journals (Sweden)

A. V. Drannikov

2017-01-01

Full Text Available Beet pulp is the main sugar industry by-product obtained with traditional production technology. It has high nutritional qualities, but in its raw form it turns sour quickly so it must be preserved. One of the most common methods is drying. Drying of the beet pulp with superheated vapor of reduced pressure in the pulsating vibro-boiling layer allows to improve the quality of the finished product by lowering of the drying agent temperature, thereby retaining a significant amount of nutrients in the initial product. To study the kinetic and hydrodynamic dependencies of the drying process, an experimental apparatus was developed that makes it possible to obtain the most accurate and reproducible results. In the course of the work, a lot of experiments were carried out. Drying curves, drying rate curves and heating curves were made based on these experiments results. According to the nature of the changes the corresponding conclusions were drawn. To study the interaction of various factors affecting the beet pulp drying process, the mathematical methods of experiment planning are applied. A mathematical description of this process can be obtained empirically. At the same time, its mathematical model has the form of a regression equation, determined by statistical methods on the basis of experiments. As a result of statistical processing of experimental data, regression equations were obtained that adequately describe the beet pulp drying process in a pulsed low-pressure vibro-boiling layer in the experimental apparatus. With reference to this drying apparatus, such technological modes of its operation were determined that ensure a minimum specific energy consumption of the drying process per kilogram of evaporated moisture and the maximum drying chamber moisture stress.

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 CO{sub 2}e/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.

Study of sugar beet viruses transmitted by Polymyxa betae in the Czech Republic

Directory of Open Access Journals (Sweden)

Rysanek Pavel

2006-01-01

Full Text Available Sugar beet viruses transmitted by Polymyxa betae are very widespread in the Czech Republic. Beet soil-borne virus (BSBV is present in almost all fields used for sugar beet growing, beet virus Q (BVQ is present in about 50% of fields but beet necrotic yellow vein virus (BNYVV is present in some limited regions only. It means that mixed infections of sugar beet by at least two viruses are quite common in the field. P. betae also occurs in almost all fields where sugar beet is now grown. Only two populations of P. betae not transmitting any virus were found. Cystosori of P. betae can harbour viruses without loosing infectivity for a very long time. We were able to detect these viruses in plants grown in soil stored dry for 12 years. BNYVV can cause serious yield losses under mideuropean conditions reaching up to 50% of sugar yield, whereas harmfulness BSBV and BVQ is questionable, because they also occur in fields with no problems concerning sugar beet growing. The host range of these viruses was studied. Both infect all types of beet (sugar fodder, red beet, mangold and spinach and usually are detectable in root system only. Other chenopodiaceous plants are infected only by some virus strains. These strains are also able to spread into above-ground parts of plants.

2011-01-01

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 13 t h and April 4 t h 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)

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

International Nuclear Information System (INIS)

Salazar-Ordóñez, Melania; Pérez-Hernández, Pedro P.; Martín-Lozano, José M.

2013-01-01

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

Sugar beet molasses: Properties and applications in osmotic dehydration of fruits and vegetables

Directory of Open Access Journals (Sweden)

Šarić Ljubiša Ć.

2016-01-01

Full Text Available Molasses is an important by-product of sugar beet or sugar cane refining industry and it was one of the first sweeteners used in human nutrition. Sugar cane molasses has unique characteristics that can make it suitable for application in food industry, especially in confectionery and bakery products. On the other hand, sugar beet molasses has not had greater application in the human diet, primarily because of its strong smell and taste of the beet, which makes it unattractive for consumption. Since recent investigations showed that sugar beet molasses can be used as a hypertonic solution in osmotic dehydration of different materials of plant and animal origin, the objective of this work was to review recently studied sugar beet molasses in terms of its applications in osmotic dehydrations of fruits and vegetables. Previous studies showed that sugar beet molasses is an excellent medium for osmotic dehydration of fruits and vegetables (apple, carrot, plum, etc. primarily due to a high content of dry matter (80%, w/w and specific nutrient content. An important advantage of using sugar beet molasses as a hypertonic solution is an enrichment of the dehydrated material in minerals and vitamins, which penetrate from molasses into the plant tissue. Concentration of sugar beet molasses solution and immersion time had the biggest influence on the process of osmotic dehydration of fruit and vegetables, while the temperature of the solution was the least influential parameter. The effect of immersion time on the kinetics of osmotic dehydration in sugar beet molasses increases with an increase in concentration of hypertonic solution. Fruit and vegetables dehydrated in sugar beet molasses had a higher dry matter content compared to samples treated in sucrose solutions. Besides, application of sugar beet molasses in osmotic dehydration of fruits and vegetables had some other advantages such as lower cost of molasses compared to sugar and its liquid aggregate

Full Text Available Sugar, which can be extracted from sugar cane and sugar beet, is one of the most important ingredients of food. Conducting more research to increase the extraction efficiency of sugar is necessary due to high production of sugar beet and its numerous processing units in northern Khorasan province. In this research, the effect of temperature, time and the frequency of ultrasonic waves on mechanical properties of sugar beet and its extraction rate of sugar in moisture content of 75% were studied. In this regard, an ultrasonic bath in laboratory scale was used. The studied parameters and their levels were frequency in three levels (zero, 25 and 45 KHz, temperature in three levels (25, 50 and 70 ° C and the imposed time of ultrasonic waves in three levels (10, 20 and 30 min. Samples were prepared using planned experiments and the results were compared with control sugar beet samples. A Saccharimeter was used to measure the concenteration of sugar in samples. Two different types of probe including semi-spherical end and the other one with sharpened edges were used to measure mechanical properties. The studied parameters of frequency, temperature and time showed significant effect on sugar extraction and their resulted effect in optimized levels revealed up to 56% increase in sugar extraction compared with control samples. The obtained values of elastic modulus and shear modulus showed a decreasing trend. The obtained values of total energy of rupture, the total energy of shear, the maximum force of rupture, and the yield point of rupture showed an increasing trend. The frequency had no significant effect on the yield point of rupture and shear force.

A total of 480 1-d-old male geese were divided into three groups whose diet differed from d 56 to 90: a complete pelleted diet containing 50% corn (control diet: AMEn 11.5 MJ/kg; CP 161 g/kg), and no SBP; a complete pelleted diet containing 50% corn and 10% SBP (SBPcp diet: AMEn: 11.5 MJ/kg; CP: 161 g/kg); and a mix in the same feeder (SBPlm diet) of 500 g/kg of protein-rich pellets containing 20% SBP (SBPprp: AMEn: 9.0 MJ/kg; CP: 250 g/kg) and 500 g/kg of whole corn (WC: AMEn: 14.0 MJ/kg; CP: 72 g/kg). Body traits, including crop volume, were measured at d 91. From d 91 to 106, 88 birds/group were overfed with a mixture containing mainly corn and water before slaughter to measure fatty liver performance. Feed intake from d 56 to 90 was higher (+10%; P = 0.004) in the SBPcp group than the other two, but at d 90, the body weight (BW) of the birds was higher (+7%; P = 0.002) in the SBPlm group than the other two. At d 91, the volume of the crop was greater in the SBPcp group (80.4 mL/kg of BW, P 0.05) between the three groups. In conclusion, the use of sugar beet pulp in the diet of finishing geese helps the adaptation of the digestive tract to the overfeeding period, even in a loose-mix feeding system based on whole corn. © 2017 Poultry Science Association Inc.

Strip-till seeder for sugar beets

Peter Schulze Lammers

2014-06-01

Full Text Available Strip-till save costs by reducing tillage on the area of sugar beet rows only. The seeding system is characterized by a deep loosening of soil with a tine combined with a share and by following tools generating fine-grained soil as seed bed. In cooperation with the Kverneland company group Soest/Germany a strip tiller combined with precision seeder was designed and tested in field experiments. Tilling and seeding was performed in one path on fields with straw and mustard mulch. Even the plant development was slower as compared to conventional sawn sugar beets the yield was on equivalent level. Further field experiments are planned to attest constant yield, cost and energy efficiency of the seeding system.

Proteomic Profiling of Sugar Beet (Beta vulgaris Leaves during Rhizomania Compatible Interactions

Directory of Open Access Journals (Sweden)

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.

Effect of Azotobacter croococcum on productive traits and microorganisms in sugar beet rhizosphere

Kuzevski Janja

2011-01-01

Full Text Available The aim of this study was to determine the effects of three different inoculation methods with selected Azotobacter chroococcum strains on productive and technological traits of sugar beet, as well as on the total number of microorganisms and azotobacter in rhizosphere. The results of this two-year study showed that effectiveness of the tested inoculation methods in increasing root yield and sugar content varies greatly, depending on year and azotobacter strains. Effectiveness of inoculation methods was not largely impacted by year on granulated sugar. Achieved granulated sugar yield was significantly higher by using pre-sowing azotobacter application, than by using seed inoculation. A significantly increased number of microorganisms in sugar beet rhizosphere was determined, not only by using pre-sowing azotobacter application but also by using sugar beet seed inoculation. Pre-sowing azotobacter application and inter-row cultivation both caused an equal increase in the number of these bacteria in sugar beet rhizosphere (42.2% and 46.9%. Use of sugar beet seed inoculation caused an increase of 33.7% in the number of azotobacter. In order to achieve higher effectiveness in applying azotobacter on productive and technological traits of sugar beet, and considering determined interaction between a certain year, an inoculation method and a strain, it is necessary for future research to focus on determining efficiency of these strains when they are in a mixture.

Differences between the rhizosphere microbiome of Beta vulgaris ssp. maritima - ancestor of all beet crops - and modern sugar beets

Directory of Open Access Journals (Sweden)

Christin eZachow

2014-08-01

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.

Capture and use of solar radiation, water, and nitrogen by sugar beet (Beta vulgaris L.).

Science.gov (United States)

Jaggard, K W; Qi, A; Ober, E S

2009-01-01

Sugar beet is spring-sown for sugar production in most sugar beet-growing countries. It is grown as a vegetative crop and it accumulates yield (sugar) from very early in its growth cycle. As long as the sugar beet plants do not flower, the sugar accumulation period is indefinite and yield continues to increase. This paper reviews the success of the sugar beet crop in capturing and using solar radiation, water and mineral nitrogen resources. The prospects for improved resource capture and therefore increased sugar yield are also considered, particularly the potential to increase solar radiation interception in the future by sowing the crop in the autumn.

2018-01-01

The reform of the European Union's sugar regime caused potential decreasing beet prices. Therefore, the Speeding Up Sugar Yield (SUSY) project was initiated. At the start, a 3 × 15 target was formulated: in 2015 the national average sugar yield in the Netherlands equals 15 t/ha (60% of the sugar beet potential) and the total variable costs 15 euro/t sugar beet, aspiring a saving on total variable costs and a strong increase in sugar yield. Based on their average sugar yield in 2000-2004, 26 pairs of "type top" (high yielding) and "type average" (average yielding) growers were selected from all sugar beet growing regions in the Netherlands. On the fields of those farmers, all measures of sugar beet cultivation were investigated, including cost calculation and recording phytopathological, agronomical and soil characteristics in 2006 and 2007. Although there was no significant difference in total variable costs, the "type top" growers yielded significantly 20% more sugar in each year compared to the "type average" growers. Therefore, the most profitable strategy for the growers is maximizing sugar yield and optimizing costs. The difference in sugar yield between growers could be explained by pests and diseases (50%), weed control (30%), soil structure (25%) and sowing date (14%), all interacting with each other. The SUSY-project revealed the effect of the grower's management on sugar yield. As a follow up for the SUSY-project, a growers' guide "Suikerbietsignalen" was published, Best Practice study groups of growers were formed and trainings and workshops were given and field days organized. Further, the benchmarking and feedback on the crop management recordings and the extension on variety choice, sowing performance, foliar fungi control and harvest losses were intensified. On the research part, a resistance breaking strain of the Beet Necrotic Yellow Vein Virus (BNYVV) and a new foliar fungus, Stemphylium beticola , were identified and options for control were

Development of Beet Sugar Production in Ryazan Region in the Context of Ensuring Food Security

Directory of Open Access Journals (Sweden)

Mansurov Ruslan Evgenyevich

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.

Full Text Available Sugar beet leaves now are very widely used for livestock feeding, as an organic fertiliser, and also as a raw material for the production of biogas. Therefore the harvest of the sugar beet tops (including leaves can be considered as current task for the sugar beet growing system. Modern technologies involve harvest of the tops of sugar beet in two stages: flat basic cut and collecting of the entire green mass at higher altitude and the subsequent cutting of the heads of root crops from the residues. Therefore, topical issues of the sensing of the heads of sugar beet roots arranged in rows, are related to the majority of the sugar beet toppers, cleaners of the sugar beet heads, leaves cutters and, digging up working bodies of some designs. The aim of this study is theoretical determination the optimum design and kinematic parameters of a new sensing mechanism of the sugar beet heads located in the soil on the basis of the theory of interaction of flat passive swath board sensing organ with the sugar beet heads during their topping when located in the soil. In the study there are used methods of creation of mathematical models of functioning of the agricultural machines and their working bodies with the using of main provisions of mathematics, theoretical mechanics, programming and numerical calculations on the PC. In this paper, there is presented a theoretical study of the interaction of passive sensing organ with the head of the sugar beet root when there are located residues of the leaves on a root head spherical surface in the form of short elastic rods. Thus, for such an interaction of the sensing organ and the head of sugar beet root head there is taken into account elastic-damping properties of the sugar beet leaves residues. In the study there was first of all developed a new design of the topper for sugar beet heads with the use of a flat swath board sensing organ, there was developed the equivalent scheme of the interaction of the

This study was planned to utilize sugar beet powder as a rich source of dietary fibre in cookies. Purposely, five treatments namely T1, T2, T3, T4 and T5 with 4%, 8%, 12%, 16% and 20% sugar beet powder addition in wheat flour were chosen to estimate fibre, antioxidant profiling and engineering properties of cookies. Results showed an increased content of all above mentioned parameters. With the increment in sugar beet powder addition in treatments, dietary fibre analysis have shown that total dietary fibre (TDF), insoluble dietary fibre (IDF) and soluble dietary fibre (SDF) have depicted increasing trend with maximum for T5 for all dietary fibre types. Significant results were obtained for in vitro antioxidant studies including total phenolic content (TPC) and DPPH that showed increasing trend with T1 0.6 mg GAE/g and maximum values for T5 with 2.0 mg GAE/g for TPC and for DPPH with T5 being maximum value of 1.7% and minimum for T1 with 1.3%. T5 treatment with 20% sugar beet gave best physicochemical results but disturbed sensory properties while T3 with 12% sugar beet powder showed good physicochemical and sensory characteristics. Therefore, T3 with 12% level is considered as the best source of dietary fibre in bakery products and can be considered as the prospective choice to address metabolic syndromes. (author)

Yield Estimation of Sugar Beet Based on Plant Canopy Using Machine Vision Methods

S Latifaltojar

2014-09-01

Full Text Available Crop yield estimation is one of the most important parameters for information and resources management in precision agriculture. This information is employed for optimizing the field inputs for successive cultivations. In the present study, the feasibility of sugar beet yield estimation by means of machine vision was studied. For the field experiments stripped images were taken during the growth season with one month intervals. The image of horizontal view of plants canopy was prepared at the end of each month. At the end of growth season, beet roots were harvested and the correlation between the sugar beet canopy in each month of growth period and corresponding weight of the roots were investigated. Results showed that there was a strong correlation between the beet yield and green surface area of autumn cultivated sugar beets. The highest coefficient of determination was 0.85 at three months before harvest. In order to assess the accuracy of the final model, the second year of study was performed with the same methodology. The results depicted a strong relationship between the actual and estimated beet weights with R2=0.94. The model estimated beet yield with about 9 percent relative error. It is concluded that this method has appropriate potential for estimation of sugar beet yield based on band imaging prior to harvest

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

International Nuclear Information System (INIS)

Maung, Thein A.; Gustafson, Cole R.

2011-01-01

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 hm 3 y -1 (or 10 MGY (Million Gallon per Year) and 0.076 hm 3 y -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 hm 3 y -1 plant is $400 m -3 ($1.52 per gallon) and $450 m -3 ($1.71 per gallon) for the 0.038 hm 3 y -1 plant. Breakeven prices for feedstocks are also estimated and show that the 0.076 hm 3 y -1 plant can tolerate greater ethanol and feedstock price risks than the 0.038 hm 3 y -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 hm 3 y -1 plant is $41.54 million. By comparison, the estimated NPV for the 0.038 hm 3 y -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 hm 3 y -1 and 0.038 hm 3 y -1 ethanol 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

As part of a long-term strategy toward renewable feedstock, a feasibility study into options for the production of bioethylene by integrating the sugar beet-to-ethanol-to-ethylene value chain. Seven business cases were studied and tested for actual economic feasibility of alternative sugar-to-ethanol-to-ethylene routes in comparison to fossil-fuel alternatives. An elaborate model was developed to assess the relevant operational and financial aspects of each business case. The calculations indicate that bioethylene from sugar beet is not commercially viable under current market conditions. In light of expected global energy and feedstock prices it is also reasonable to expect that this will not change in the near future. To consider biorenewable sources as starting material, they need to be low in cost (compared to sugar beets) and also require less capital and energy-intensive methods for the conversion to chemicals. In general, European sugar prices will be too high for many chemical applications. Future efforts for in sugar-to-chemicals routes should, therefore, focus on integrated process routes and process intensification and/or on products that contain a significant part of the original carbohydrate backbone.

Stasiak, D.M.

2005-01-01

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

Full Text Available Sugar beet (Beta vulgaris L. - one of the most important crop in the world. In Kazakhstan, it is a traditional and major source of domestic sugar. The industry of cultivation and production of sugar beet is one of the priority areas of agricultural development of the country. In this paper, we studied the regeneration ability of different genotypes of sugar beet explants on selective media with the culture filtrate of the pathogen fungus F. oxysporum var. orthoceras. From the roots and shoots of sugar beet the pathogen Fusarium root rot was isolated. Was obtained pure cultures of the isolated pathogen. As a result, of morphological and cultural descriptions, as well as microbiological analysis it was revealed that the isolated pathogen is Fusarium Oxysporum. The results showed the pathogenicity of the fungus. For regeneration in vitro of the sugar beet genotypes resistant to the pathogen the culture media was optimized to the culture filtrate of the fungus F. oxysporum var. orthoceras. The frequency of shoot regeneration, depending on the genotype, was 1,0-12,5 %. On these explants the multiple shoot formations were observed.

Anaerobic digestion was investigated as a potential method for on-farm disposal of fallen stock (pig carcases), degrading the carcase material to produce biogas and digestate. The effects of feedstock (sugar beet pulp or pig carcase material or a 50:50 mix) and organic loading rate (50 g-TS L -1 or 100 g-TS L -1 ), during mesophilic (35 °C) anaerobic digestion were investigated. Anaerobic digestion was achieved for all experimental treatments, however the pig carcase material at the higher organic loading rate produced the second highest methane yield (0.56 Nm 3 kg-VS -1 versus a range of 0.14-0.58 Nm 3 kg-VS -1 for other treatments), with the highest percentage of methane in total biogas (61.6% versus a range of 36.1-55.2% for all other treatments). Satisfactory pathogen reduction is a legislative requirement for disposal of carcase material. Pathogens were quantified throughout the anaerobic digestion process. Enterococcus faecalis concentrations decreased to negligible levels (2.8 log 10 CFU g-TS -1 ), whilst Clostridium perfringens levels remained unaffected by treatment throughout the digestion process (5.3 ± 0.2 log 10 CFU g-TS -1 ).

Increase of saline lands in most regions of the world and Iran, limit of production increase based on land enhancement and also threat of saline water and soils for crop production make related researches and production of salt tolerant variety to be more serious. There have been many researches about salt stress in Sugar Beet Seed Institute of Iran (SBSI) during several years. Accordingly, the new screening methods for stress tolerance to be continued based on these researches. Previous researches in SBSI were reviewed and results concluded to this study which is presented in this article in three categories including: Agronomy, Breeding and Biotechnology. In agronomy researches, suitable planting medium, EC, growth stage and traits for salinity tolerance screening were determined and agronomic technique such as planting date, planting method and suitable nutrition for sugar beet under salt stress were introduced. Sand was salinizied by saline treatments two times more than Perlit so large sized Perlit is suitable medium for saline studies. Sugar beet genotypes screening for salt tolerance and should be conducted at EC=20 in laboratory and EC= 16 dS/M in greenhouse. Although sugar beet seed germination has been known as more susceptible stage to salinity, it seems establishment is more susceptible than germination in which salinity will cause 70-80% decrease in plant establishment. Measurements of leaves Na, K and total carbohydrate at establishment stage would be useful for faster screening of genotypes, based on high and significant correlation of these traits at establishment with yield at harvest time. In breeding section, SBSI genotypes with drought tolerance background would be useful for salinity stress studies and finally there is a need for more research in the field of biotechnology in Iran.

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

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.

This study tested the hypothesis that the easily degradable carbohydrates of the sugar beet silage (S) will improve the anaerobic digestion of grass silage (G) more profoundly compared to co-digestion of sugar beet silage with maize silage (M). M : S and G : S mixtures were tested in two continuous laboratory-scale AD experiments at volatile solid ratios of 1 : 0, 6 : 1, 3 : 1, and 1 : 3 at organic loading rates of 1.5 kgVS m−3 day−1. While the sugar beet effects in mixtures with maize silage were negligible, co-digestion with grass silage showed a beneficial performance. There, the specific methane production rate was 0.27 lN kg−1VS h−1at G : S ratio of 6 : 1 compared to G : S 1 : 0 with 0.14 lN kg−1VS h−1. In comparison to G : S 1 : 0, about 44% and 62% higher biogas yields were obtained at G : S 6 : 1 and 3 : 1, respectively. Also, the highest methane concentration was found in G : S at ratio of 1 : 3. Synergistic increase of methane yield was found in co-digestion in both experiments, but higher effect was realized in G : S, independently of the amount of sugar beet silage. The findings of this study emphasize the improvement of AD of grass silage by even low addition of sugar beet silage. PMID:27807538

Worldwide nowadays, relying on the second generation bioethanol from the lignocellulosic feedstock is a mandatory aim. However, one of the major drawbacks for high ethanol yield is the physical and chemical pretreatment of this kind of feedstock. As the pretreatment is a crucial process operation that modifies the lignocellulosic structure and enhances its accessibility for the high cost hydrolytic enzymes in an attempt to maximize the yield of the fermentable sugars. The objective of this work was to optimize and integrate a physicochemical pretreatment of one of the major agricultural wastes in Egypt; the sugar beet pulp (SBP) and the enzymatic saccharification of the pretreated SBP using a whole fungal cells with a separate bioethanol fermentation batch processes to maximize the bioethanol yield. The response surface methodology was employed in this study to statistically evaluate and optimize the conditions for a thermal acid pretreatment of SBP. The significance and the interaction effects of the concentrations of HCl and SBP and the reaction temperature and time were studied using a three-level central composite design of experiments. A quadratic model equation was obtained to maximize the production of the total reducing sugars. The validity of the predicted model was confirmed. The thermally acid pretreated SBP was further subjected to a solid state fermentation batch process using Trichoderma viride F94. The thermal acid pretreatment and fungal hydrolyzes were integrated with two parallel batch fermentation processes of the produced hydrolyzates using Saccharomyces cerevisiae Y39, that yielded a total of ≈ 48 g/L bioethanol, at a conversion rate of ≈ 0.32 g bioethanol/ g SBP. Applying the proposed integrated process, approximately 97.5 gallon of ethanol would be produced from a ton (dry weight) of SBP.

2017-05-01

Full Text Available Introduction Sugar beet (Beta vulgaris L. as the second most important world’s sugar source after sugarcane is one of the major industrial crops. The presence of weeds in sugar beet fields, especially at early growth stages, results in a substantial decrease in the crop yield. It is very important to efficiently eliminate weeds at early growing stages. The first step of precision weed control is accurate detection of weeds location in the field. This operation can be performed by machine vision techniques. Hough transform is one of the shape feature extraction methods for object tracking in image processing which is basically used to identify lines or other geometrical shapes in an image. Generalized Hough transform (GHT is a modified version of the Hough transform used not only for geometrical forms, but also for detecting any arbitrary shape. This method is based on a pattern matching principle that uses a set of vectors of feature points (usually object edge points to a reference point to construct a pattern. By comparing this pattern with a set pattern, the desired shape is detected. The aim of this study was to identify the sugar beet plant from some common weeds in a field using the GHT. Materials and Methods Images required for this study were taken at the four-leaf stage of sugar beet as the beginning of the critical period of weed control. A shelter was used to avoid direct sunlight and prevent leaf shadows on each other. The obtained images were then introduced to the Image Processing Toolbox of MATLAB programming software for further processing. Green and Red color components were extracted from primary RGB images. In the first step, binary images were obtained by applying the optimal threshold on the G-R images. A comprehensive study of several sugar beet images revealed that there is a unique feature in sugar beet leaves which makes them differentiable from the weeds. The feature observed in all sugar beet plants at the four

2014-01-01

Full Text Available Summary. One of the major causes of decline in the quality of granulated sugar is bacterial contamination of sugar beet. This is due to the fact that the beet-sugar industry is a good object for the development of different groups of microorganisms. The main sources of infection of products of sugar manufacture can be soil, water, air, packaging, packaging materials, vehicles, clothing, equipment. The higher the beet contamination with the microorganisms, the more they decompose sucrose and secrete metabolic byproducts. In this regard, there is a need to reduce the negative impact of various groups of microorganisms and to minimize the loss of sucrose from decomposition. In accordance with the problem given the studies to determine the bacteriostatic properties of chlorinated compounds for sugar production were carried out. We used the cultivated fluid colonized with a pure culture of Leuconostoc mesenteroides and reagent treated as an object of study. In the experiments, we determined the accumulation of biomass of L. mesenteroides with nephelometric method by measuring the optical density of bacterial suspension. It was found out that after 24 hours of bacterial culturing the level of optical density in the control and active acidity were considerably higher compared with the sample treated with germicide. The number of microorganisms in the nutrient medium was determined by Vinogradsky-Shulgina-Brid’s. According to the study in the control is 1,7*10^16, in experiment with the introduction of the chlorinated compound it is 5,8*10^14. The experimental results show that the investigated chlorinated compound has bacteriostatic action against grampositive cocci saprophytic of L. mesenteroides and can be recommended for use in a sugar beet production.

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)

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.

Full Text Available Abstract Dodder is an annual parasitic plant that has not chlorophyll. This parasitic plant can attach to many field crops such as sugar beet. Also this parasite consumes some water, nutrients and assimilates from plants which result in decreasing of quality and quantity of crops yield. This study carried out in Chenaran county, Khorasan Razavi province, in order to evaluation of damage effects of dodder on qualitative and quantitative traits of sugar beet in 2006. Three fields which naturally formerly have infested by dodder, selected in three locations (Ghezlar, Masi Hazrati and Moghan. Sowing date was nearly in April in all fields. At the harvest time, in November, in each field 20 sample of sugar beet roots separately were harvested. Harvest area of each sample was 8m2. Each sample selected from spots which indicated nearly 80-100 percentage infestation. Observations were paired samples and then 20 samples of uninfested spots (with zero percentage infestation at neighboring rows of infested spots with the same area (8m2 were harvested. Samples were analyzed with qualitative and quantitative standard methods. Obtained data were analyzed by SAS Software with t test and samples compaired in pairwise comparisons. Results indicated that dodder in all sugar beet fields reduced root yield (RY, sugar content(SC, sugar yield (SY, white sugar content (WSC, yield, white sugar yield (WSY, 15.07% , 1.06 Unit, 20.35 %, 7.40 %, 1.89 Unit and 17.73%, respectively. Root potassium content and harmful nitrogen content on field infested spots reduced (8.55% and 8.02 % respectively, but Na content increased 24.3% and molasses Sugar content (MS increased 11.16 %. Conclusion from this experiment showed that dodder damage and its harmful effects were highly significant in all farms in Chenaran. Therefore consideration of field sanitation related to attachment of dodder to sugar beet is completely necessary. Also it had better consider methods of dodder control

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.

Emissions of greenhouse gases such as CO 2 , CO, CH 4 and NO X 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 m 3 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. (author)

Suhartini, S.; Heaven, S.; Banks, C. J.

2018-03-01

Anaerobic digestion (AD), known as a biological process without oxygen to convert complex organic materials into biogas, is capable of processing large tonnage quantities of biomass, such as sugar beet pulp (SBP). In addition to biogas production, its use allows nutrients and organic carbon recycle back to agriculture through the spreading of digestate. Digestate still contains high amount of nutrients (N, P, K) for use as biofertiliser. The aims of this research were to determine biogas/methane potential as a baseline for comparison with performance in semi-continuous digestion, and to determine nutrient and potentially toxic elements (PTE) of digestate fractions with respect to their potential for utilisation in agriculture. The Biochemical Methane Potential (BMP) test was performed in triplicate against blank and positive controls over a period of 28 days with gas measured at regular intervals. Semi-continuous AD of SBP was operated under mesophilic and thermophilic condition for 206 and 165 days. The results indicated that SBP is a very promising feedstock for AD, with the average BMP of 0.321 l CH4 g-1 VS and biogas potential of 0.605 l g-1 VS. Under semi-continuous operation, SBP also demonstrated positive results. Digestates from mesophilic and thermophilic AD of SBP contained useful quantities of N, P and K, with an acceptable Ni concentration in accordance to limits for PTE. These results suggest that digestate has the potential to be utilised on agricultural and arable land. This study illustrated the positive effects of applying AD to the achievement of economic savings and environmental-friendly performance.

Full Text Available Introduction: Weed competition is one of the major factors which limit sugar beet production in the world. Weed – crop interactions are based on competition for water, nutrients and light and allelopathic effects may also play a small role. In sugar beet weed interference, all these factors are important too, but the light is of prime importance. Due to the fact that a lot of weeds can grow above the sugar beet canopy and reduce the amount of photosynthetic radiation reaching the crop, these weeds are stronger competitors compared to smaller weeds. In much sugar beet growing areas dicot weeds of the families Chenopodiaceae, Asteraceae, Brassicaceae and Polygonaceae are of major importance. The monocots are less important compared to dicot weeds. Competition from uncontrolled annual weeds that emerge within 8 weeks of sowing or within 4 weeks of the crop reaching the two-leaf stage can reduce root yields by 26–100% .Weeds that emerge 8 weeks after sowing, and particularly after the sugar beet plants have eight or more leaves, are less likely to affect yield. Although tractor hoeing and hand labour are still used in many production areas, herbicides have been the primary method of weed control in sugar beet. The effectiveness of pre-emergence residual herbicides decreases with reductions in rainfall or soil wet content. Therefore, less than 10 % of the total sugar beet crop is treated with pre-emergence herbicides. The remaining 90 % depends solely on a selection of post-emergence herbicides to maintain season-long weed control. The major herbicides are phenmedipham, chloridazon, metamitron. Mixtures of post-emergence, broad spectrum herbicides have to be applied to control the wide range of weed species in sugar beet crops. Materials and Methods: To study the effects of weeds control by hand weeding and herbicides combination with two selective herbicides at different levels of nitrogen application on sugar beet yield and quality

Full Text Available To investigate the effect of water stress and rewatering on sugar beet yield and its corresponding photosynthetic parameters, and to provide the basis of water management for the sugar beet fields, pool experiments in an artificial proof canopy were set up to observe changes of beet net photosynthetic rate(Pn, transpiration rate(Tr, water use efficiency(WUE and stomatal limitation (Ls, intercellular CO2 oncentration(Ci, and PSⅡ maximum quantum yield(Fv/Fm. The results indicated that the diurnal variation of Tr and Pn in CK treatment (whole growth period replenishment at different times near "unimodal" type; and water shortage treatments presented "twin peaks" change. Diurnal transpiration capacity(DTC under water stress at sugar accumulation stage reduced by 70.16%~74.81% and diurnal photosynthetic capacity(DPC was 63.48%~69.96% lower than that of CK, while diurnal water use efficiency(WUEd increased by 19.28%~22.39%. Rehydration helped Tr and Pn recovery, but did not reach unstressed levels. Ls changes under extremely dry environment had a midday trough "twin peaks" feature, and Ci was at "double-dip" in consistent with the timing of Ls; Water stress inhibited and inactivated photochemical reaction center of midday PSⅡ. Water stress led to irreversible decrease in the Pn and Tr, and prolonged the Pn inefficient period, which become the important factor of influencing the sugar beet yield.

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.

Full Text Available Sugar beet is one of strategic products to supply sugar in water limited areas of Iran. Thus, proper managements to supply enouph water in production of sugar beet is very important. To evaluate the effects of some anti stress substances like salicylic acid, tyuful and glycine to irritigate the effect of early water deficit on suger beet, an experiment based on randomized complete block design with three replications was carried out at the Research Farm of Fariman Sugar Factory in 2013. Treatments consisted of control (without using anti stress substances, with three concentration of salicylic acid (0.1, 0.5, and 1 mM, tyuful with three concentration (0.5, 1 and 1.5 liter per thousand and glycine with three concentration (1, 2 and 3 liters per thousand. The results showed that the effects of anti-stress materials significantly affected the sugar content, root yield, white sugar yield and harmful nitrogen. Highest sugar content (15.65%, root yield (83.82 t.ha-1 and white sugar percentage (11.15% were obtained by using tyuful 1.5 lit/1000. While, the lowest levels of these characters were obtained from control (not using anti stress substances. Maximum harmful nitrogen was produced in control treatment (4.38 and highest level of alkalinity with mean of 3.49 was observed by using 3 lit/1000 of glycine. Our results showed that all of the anti stress substances had positive effects on sugar beet under drought stress condition.

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.

Effect of residual nitrogen and fertilizer nitrogen on sugar beet production in Finland

Directory of Open Access Journals (Sweden)

Veikko Brummer

1974-09-01

Full Text Available Preliminary determinations for NO3- and NH4-N in topsoil from nitrogen field experiments are discussed. The amounts of residual nitrogen as well as the dates and depth for sampling are considerd in order to investigate the need of fertilizer-N for continuous sugar beet. Tops ploughed down as manure increased the available soil nitrogen by about 50 kg/ha. In practice nitrogen from fertilizer and farmyard manure given to previous beet crops seems to accumulate in the beet soils of Finland. The concentrations of nitrate and ammonium nitrogen in topsoil were low in the spring of 1972 and 1973. NO3-N increased in topsoil during the early summer, and the highest concentrations were found at the beginning of July. Starting from the middle of July the amount of NH4-N began to increase both in topsoil and in subsoil. With increasing amounts of nitrogen in the topsoil the sugar content decreases continuously. Also the α-amio N content of beets correlates with the soil nitrogen. There is experimental evidence that 150 180 kg/ha nitrate nitrogen in topsoil (residual + fertilizer N in early July gives the best economic result. The effects of fertilizer and accumulated soil nitrogen on the sugar beet quality together with som other experimental data have been statistically analysed. Regression coefficients indicated that both forms of nitrogen affected the suger content, the α-amino N concentration and clear juice purity, in a similar way.

The addition of sugar beet to ethanol pathway in GHGenius

International Nuclear Information System (INIS)

2007-01-01

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 (CO 2 ) 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

Remoroza, C; Buchholt, H C; Gruppen, H; Schols, H A

2014-01-30

Enzymatic fingerprinting was applied to sugar beet pectins (SBPs) modified by either plant or fungal pectin methyl esterases and alkali catalyzed de-esterification to reveal the ester distributions over the pectin backbone. A simultaneous pectin lyase (PL) treatment to the commonly used endo-polygalacturonase (endo-PG) degradation showed to be effective in degrading both high and low methylesterified and/or acetylated homogalaturonan regions of SBP simultaneously. Using LC-HILIC-MS/ELSD, we studied in detail all the diagnostic oligomers present, enabling us to discriminate between differently prepared sugar beet pectins having various levels of methylesterification and acetylation. Furthermore, distinction between commercially extracted and de-esterified sugar beet pectin having different patterns of substitution was achieved by using novel descriptive pectin parameters. In addition to DBabs approach for nonmethylesterified sequences degradable by endo-PG, the "degree of hydrolysis" (DHPG) representing all partially saturated methylesterified and/or acetylated galacturonic acid (GalA) moieties was introduced as a new parameter. Consequently, the description DHPL has been introduced to quantify all esterified unsaturated GalA oligomers. Copyright © 2013 Elsevier Ltd. All rights reserved.

Study of the production of ethanol from sugar beets for use as a motor fuel. Final report, February 1, 1980-April 30, 1981

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)

The aim of the present work was to study the ability of a halophilic bacterial laccase to efficient delignification in extreme conditions. Here, a highly stable extracellular laccase showing ligninolytic activity from halophilic Aquisalibacillus elongatus is described. The laccase production was strongly influenced by NaCl and CuSO 4 and under optimal conditions reached 4.8UmL -1 . The monomeric enzyme of 75kDa was purified by a synthetic affinity column with 68.2% yield and 99.8-fold purification. The enzyme showed some valuable features viz. stability against a wide range of organic solvents, salts, metals, inhibitors, and surfactants and specificity to a wide spectrum of substrates diverse in structure and redox potential. It retained more than 50% of the original activity at 25-75°C and pH 5.0-10.0. Furthermore, the enzyme was found to be effective in the delignification of sugar beet pulp in an ionic liquid that makes it useful for industrial applications. Copyright © 2017 Elsevier Ltd.

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.)

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. 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. 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. 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.

In sugar beet production, weed control is one of the most important and most expensive practices to ensure yield. Since glyphosate-resistant sugar beets are not yet approved for cultivation in the EU, little commercial experience exists with these sugar beets in Europe. Experimental field trials were conducted at five environments (Germany, Poland, 2010, 2011) to compare the effects of glyphosate with the effects of conventional weed control programs on the development of weeds, weed control efficiency and yield. The results show that the glyphosate weed control programs compared to the conventional methods decreased not only the number of herbicide applications but equally in magnitude decreased the dosage of active ingredients. The results also showed effective weed control with glyphosate when the weed covering was greater and sugar beets had a later growth stage of four true leaves. Glyphosate-resistant sugar beets applied with the glyphosate herbicide two or three times had an increase in white sugar yield from 4 to 18 % in comparison to the high dosage conventional herbicide systems. In summary, under glyphosate management sugar beets can positively contribute to the increasingly demanding requirements regarding efficient sugar beet cultivation and to the demands by society and politics to reduce the use of chemical plant protection products in the environment.

Full Text Available Introduction. Sugar beet cyst nematode, Heterodera schachtii Schmidt is the major disease of sugar beet worldwide, causing considerable damages, and even death of the plants, in the infested fields. There are several suggested methods of controls, which may have its own difficulties to be taken into consideration. To avoid the use of nematicides, and reduced the risk of chemical hazards in the environment, any sorts of nonchemical management is incorrigible. However, any method of management must be safe, large scale application and economical. Thus, in this manuscript, polyethylene sheaths were used to solarize and or disinfection of the infested soils to H. schachtii. And, also, the incorporation of the farm yards manure was taken into consideration too. Therefore, the field experiments were carried out in infected sugar beet growing regions, where there was a heavy infestation to the sugar beet nematodes, Isfahan province, Iran, to determine the effects of soil solarization alone and or along with undecomposed farm yard manure on sugar beet cyst nematode, H. schachtii. Material and Methods. Transparent Polyethylene sheaths of 2microns were used to solarize and or disinfection of the infested soils to H. schachtii. The fresh farm yards manure for 40 tons per hector for the incorporation was taken into consideration. The field experiments were carried out in infected sugar beet growing regions, where, there was a heavy infestation to the sugar beet nematodes, Jey and Ghahab of Isfahan, Isfahan province, Iran, for determination of the effects of soil solarization alone and or along with undecomposed farm yard manure on sugar beet cyst nematode, H. schachtii. Treatments were consisted of soil solarization with transparent polyethylene sheets, fresh yard manure, integration of soil solarization with farm yard manure and untreated, control and or ckecks in a randomized block design in three replications each in an infested field conditions, in the

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.

The yields of fermentable sugar and EtOH were determined on spruce chips pulped with NH/sub 4/HSO/sub 3/ and Ca(HSO/sub 3/)/sub 2/. The yield of fermentable sugar is plotted vs the yield of pulp; the curve shows a difference in sugar content for the two bases during the first part of the process. With yields of pulp below 44%, this difference disappears. Univalent ions (other than NH/sub 4//sup +/) have a beneficial effect on the sugar yield. Consequently, the destruction of the sugar is more rapid when NH/sub 4//sup +/ is used.

Four multiparous (126±13d in milk) and 4 primiparous (121±11d in milk) Holstein cows were used in a 4×4 Latin square design experiment with 4 periods of 21d. Each period had 14d of adaptation and 7d of sampling, and parity was the square. Dietary treatments were (dry matter basis): 16% of dietary dry matter as corn silage without BP (0BP, control diet); 8% corn silage and 8% beet pulp (8BP); 4% corn silage and 12% beet pulp (12BP); and 0% corn silage and 16% beet pulp (16BP). Alfalfa hay was included in all diets (24% dietary dry matter). Dietary concentrations of forage neutral detergent fiber and nonfiber carbohydrates were 21.3 and 39.2% (0BP), 16.5 and 40.9% (8BP), 14.1 and 42.2% (12BP), and 11.7 and 43.4% (16BP), respectively (dry matter basis). The ambient temperature-humidity index indicated that the cows were in heat stress for almost the entire duration of the study. Dry matter intake and nutrient digestibilities were similar across treatments and between multi- and primiparous cows. Mean rumen pH tended to decrease with increasing proportions of beet pulp in the diet. Also, increasing proportions of beet pulp in the diet linearly decreased acetate and butyrate concentrations in the rumen and increased propionate concentrations, leading to a linear decrease in acetate:propionate ratio. Milk yield linearly increased (38.5, 39.3, 40.9, and 39.6kg/d for 0BP, 8BP, 12BP, and 16BP, respectively), but fat content linearly decreased (3.46, 3.47, 3.27, and 2.99), such that we observed no effect on fat-corrected milk. Substituting beet pulp for corn silage increased the neutral detergent insoluble crude protein content of the diet, leading to a decrease in rumen concentration of

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.

The effects of field dodder on physiological and anatomical processes in untreated sugar beet plants and the effects of propyzamide on field dodder were examined under controlled conditions. The experiment included the following variants: N-noninfested sugar beet plants (control); I - infested sugar beet plants (untreated), and infested plants treated with propyzamide (1500 g a.i. ha -1 (T 1 ) and 2000 g a.i. ha -1 (T 2 )). The following parameters were checked: physiological-pigment contents (chlorophyll a, chlorophyll b, total carotenoids); anatomical -leaf parameters: thickness of epidermis, parenchyma and spongy tissue, mesophyll and underside leaf epidermis, and diameter of bundle sheath cells; petiole parameters: diameter of tracheid, petiole hydraulic conductance, xylem surface, phloem cell diameter and phloem area in sugar beet plants. A conventional paraffin wax method was used to prepare the samples for microscopy. Pigment contents were measured spectrophotometrically after methanol extraction. All parameters were measured: prior to herbicide application (0 assessment), then 7, 14, 21, 28 and 35 days after application (DAA). Field dodder was found to affect the pigment contents in untreated sugar beet plants, causing significant reductions. Conversely, reduction in the treated plants decreased 27% to 4% for chlorophyll a, from 21% to 5% for chlorophyll b, and from 28% to 5% for carotenoids (T 1 ). Also, in treatment T 2, reduction decreased in infested and treated plants from 19% to 2% for chlorophyll a, from 21% to 2% for chlorophyll b, from 23% to 3% for carotenoids and stimulation of 1% and 2% was observed 28 and 35 DAA, respectively. Plants infested (untreated) by field dodder had lower values of most anatomical parameters, compared to noninfested plants. The measured anatomical parameters of sugar beet leaves and petiole had significantly higher values in noninfested plants and plants treated with propyzamide than in untreated plants. Also, the

Sugar beet (Beta vulgaris) Fusarium yellows is caused by Fusarium oxysporum f. sp. betae and can lead to significant reductions in root yield, sucrose percentage, juice purity, and storability. F. oxysporum f. sp. betae can be highly variable and many F. oxysporum strains isolated from symptomatic sugar beet are nonpathogenic. Identifying pathogenicity factors and their diversity in the F. oxysporum f. sp. betae population could further understanding of how this pathogen causes disease and potentially provide molecular markers to rapidly identify pathogenic isolates. This study used several previously described fungal effector genes (Fmk1, Fow1, Pda1, PelA, PelD, Pep1, Prt1, Rho1, Sge1, Six1, Six6, Snf1, and Ste12) as genetic markers, in a population of 26 pathogenic and nonpathogenic isolates of F. oxysporum originally isolated from symptomatic sugar beet. Of the genes investigated, six were present in all F. oxysporum isolates from sugar beet (Fmk1, Fow1, PelA, Rho1, Snf1, and Ste12), and seven were found to be dispersed within the population (Pda1, PelD, Pep1, Prt1, Sge1, Six1, and Six6). Of these, Fmk1, Fow1, PelA, Rho1, Sge1, Snf1, and Ste12 were significant in relating clade designations and PelD, and Prt1 were significant for correlating with pathogenicity in F. oxysporum f. sp. betae.

2015-12-01

Full Text Available Introduction Crop productivity is highly constrained by water and nitrogen limitations in many areas of the world (Kalra et al., 2007. Therefore, there is a need to investigate more on nitrogen and water management to achieve higher production as well as quality. Irrigated sugar beet in the cropping systems of Khorasan province in northeastern of Iran accounts for about 34% of the land area under sugar beet production (~115,000 ha with an average yield of around 36 t.ha-1 (Anonymous, 2009. However, there is a huge yield gap (the difference between potential and water and nitrogen-limited yield mainly due to biotic and abiotic factors causing major reduction in farmers’ yield. Accordingly, yield gap analysis should be carried out to reduce the yield reduction and reach the farmer’s yield to the potential yield. The current study aimed to simulate potential yield as well as yield gap related to water and nitrogen shortage in the major sugar beet-growing areas of Khorasan province of Iran. Materials and methods This study was carried out in 6 locations across Khorasan province, which is located in the northeast of Iran. Long term weather data for 1986 to 2009 were obtained from Iran Meteorological Organization for 6 selected locations. The weather data included daily sunshine hours (h, daily maximum and minimum temperatures (◦C, and daily rainfall (mm. Daily solar radiation was estimated using the Goudriaan (1993 method. The validated SUCROSBEET model (Deihimfard, 2011; Deihimfard et al., 2011 was then used to estimate potential, water and nitrogen-limited yield and yield gap of sugar beet for 6 selected locations across the Khorasan province in the northeast of Iran. This model simulates the impacts of weather, genotype and management factors on crop growth and development, soil water and nitrogen balance on a daily basis and finally it predicts crop yield. The model requires input data, including local weather and soil conditions, cultivar

Pervin, Lia; Islam, Md Saiful

2015-02-01

The aim of this study was to develop a system dynamics model for computation of yields and to investigate the dependency of yields on some major climatic parameters, i.e. temperature and rainfall, for Beta vulgaris subsp. (sugar beet crops) under future climate change scenarios. A system dynamics model was developed which takes account of the effects of rainfall and temperature on sugar beet yields under limited irrigation conditions. A relationship was also developed between the seasonal evapotranspiration and seasonal growing degree days for sugar beet crops. The proposed model was set to run for the present time period of 1993-2012 and for the future period 2013-2040 for Lethbridge region (Alberta, Canada). The model provides sugar beet yields on a yearly basis which are comparable to the present field data. It was found that the future average yield will be increased at about 14% with respect to the present average yield. The proposed model can help to improve the understanding of soil water conditions and irrigation water requirements of an area under certain climatic conditions and can be used for future prediction of yields for any crops in any region (with the required information to be provided). The developed system dynamics model can be used as a supporting tool for decision making, for improvement of agricultural management practice of any region. © 2014 Society of Chemical Industry.

Haplotype Variation of Flowering Time Genes of Sugar Beet and Its Wild Relatives and the Impact on Life Cycle Regimes

Directory of Open Access Journals (Sweden)

Nadine Höft

2018-01-01

Full Text Available The species Beta vulgaris encompasses wild and cultivated members with a broad range of phenological development. The annual life cycle is commonly found in sea beets (ssp. maritima from Mediterranean environments which germinate, bolt, and flower within one season under long day conditions. Biennials such as the cultivated sugar beet (B. vulgaris ssp. vulgaris as well as sea beets from northern latitudes require prolonged exposure to cold temperature over winter to acquire floral competence. Sugar beet is mainly cultivated for sugar production in Europe and is likely to have originated from sea beet. Flowering time strongly affects seed yield and yield potential and is thus a trait of high agronomic relevance. Besides environmental cues, there are complex genetic networks known to impact life cycle switch in flowering plants. In sugar beet, BTC1, BvBBX19, BvFT1, and BvFT2 are major flowering time regulators. In this study, we phenotyped plants from a diversity Beta panel encompassing cultivated and wild species from different geographical origin. Plants were grown under different day length regimes with and without vernalization. Haplotype analysis of BTC1, BvBBX19, BvFT1, and BvFT2 was performed to identify natural diversity of these genes and their impact on flowering. We found that accessions from northern latitudes flowered significantly later than those from southern latitudes. Some plants did not flower at all, indicating a strong impact of latitude of origin on life cycle. Haplotype analysis revealed a high conservation of the CCT-, REC-, BBX-, and PEBP-domains with regard to SNP occurrence. We identified sequence variation which may impact life cycle adaptation in beet. Our data endorse the importance of BTC1 in the domestication process of cultivated beets and contribute to the understanding of distribution and adaption of Beta species to different life cycle regimes in response to different environments. Moreover, our data provide a

Highlights: • GHG-emission, bioenergy yield, GHG-saving potential based on field trial data. • Results complement the absence of default values, especially for sugar beet. • Results represent Central European conditions of crop and biogas production. - Abstract: The study delivers values on greenhouse gas (GHG)-emission via cultivation of silage maize and sugar beet and of GHG-saving potential of electricity produced from biogas out of both biomass crops. Data are based on three rainfed crop rotation field trials in Germany (2011–2014) representative for Central Europe and can serve as default values. It was found that GHG-emission via crop cultivation was driven mainly by nitrous oxide emission from soil and mineral N-fertilizer use and was 2575–3390 kg carbon dioxide equivalents (CO_2eq) per hectare for silage maize and 2551–2852 kg CO_2eq ha"−"1 for sugar beet (without biogas digestate application). Integrating a GHG-credit for surplus N in the biogas digestate reduced total GHG-emission via crop cultivation to 65–69% for silage maize but only to 84–97% for sugar beet. The GHG-saving potential of electricity production from biogas was calculated for three biogas plants differing in technical characteristics. The GHG-saving potentials were generally >70% (silage maize: 78–80%, sugar beet: 72–76%) and the authors concluded that the technical setting of the biogas plant had a slight impact only. Overall, the authors assumed that the major potential for GHG-emission's reduction along the bioenergy production chain were N-management during crop cultivation and methane losses at the biogas plant. Finally, sugar beet, if cultivated in crop rotation, was shown to be an efficient alternative to silage maize as a biomass crop in order to achieve a higher diversity in biomass crop cultivation.

KEY MESSAGE : Here, we describe a new developed quantitative real-time PCR method for the detection and quantification of a new specific endogenous reference gene used in GMO analysis. The key requirement of this study was the identification of a new reference gene used for the differentiation of the four genomic sections of the sugar beet (Beta vulgaris L.) (Beta, Corrollinae, Nanae and Procumbentes) suitable for quantification of genetically modified sugar beet. A specific qualitative polymerase chain reaction (PCR) assay was designed to detect the sugar beet amplifying a region of the adenylate transporter (ant) gene only from the species of the genomic section I of the genus Beta (cultivated and wild relatives) and showing negative PCR results for 7 species of the 3 other sections, 8 related species and 20 non-sugar beet plants. The sensitivity of the assay was 15 haploid genome copies (HGC). A quantitative real-time polymerase chain reaction (QRT-PCR) assay was also performed, having high linearity (R (2) > 0.994) over sugar beet standard concentrations ranging from 20,000 to 10 HGC of the sugar beet DNA per PCR. The QRT-PCR assay described in this study was specific and more sensitive for sugar beet quantification compared to the validated test previously reported in the European Reference Laboratory. This assay is suitable for GMO quantification in routine analysis from a wide variety of matrices.

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.

UAVs are becoming an important tool for field monitoring and precision farming. A prerequisite for observing and analyzing fields is the ability to identify crops and weeds from image data. In this paper, we address the problem of detecting the sugar beet plants and weeds in the field based solely on image data. We propose a system that combines vegetation detection and deep learning to obtain a high-quality classification of the vegetation in the field into value crops and weeds. We implemented and thoroughly evaluated our system on image data collected from different sugar beet fields and illustrate that our approach allows for accurately identifying the weeds on the field.

The subject of this study was to investigate the feasibility of the concentrate obtained after membrane ultrafiltration of sugar beet thin juice for ethanol production and selection of fermentation conditions (yeast strain and media supplementation). Resulting concentrate was subjected to batch ethanol fermentation using two strains of Saccharomyces cerevisiae (Ethanol Red and Safdistill C-70). The effect of different forms of media supplementation (mineral salts: (NH4)2SO4, K2HPO4, MgCl2; urea+Mg3(PO4)2 and yeast extract) on the fermentation course was also studied. It was stated that sugar beet juice concentrate is suitable for ethanol production yielding, depending on the yeast strain, ca. 85-87 g L(-1) ethanol with ca. 82% practical yield and more than 95% of sugars consumption after 72 h of fermentation. Nutrients enrichment further increased ethanol yield. The best results were obtained for media supplemented with urea+Mg3(PO4)2 yielding 91.16-92.06 g L(-1) ethanol with practical yield ranging 84.78-85.62% and full sugars consumption. Copyright © 2013.

Full Text Available Cercospora leaf spot (CLS is one of the most serious leaf diseases for sugar beet (Beta vulgaris L. worldwide. The breeding of sugar beet cultivars with both high CLS resistance and high yield is a major challenge for breeders. In this study, we report the nuclear magnetic resonance (NMR-based metabolic profiling of field-grown leaves for a subset of sugar beet genotypes harbouring different levels of CLS resistance. Leaves were collected from 12 sugar beet genotypes at four time points: seedling, early growth, root enlargement, and disease development stages. 1H-NMR spectra of foliar metabolites soluble in a deuterium-oxide (D2O-based buffer were acquired and subjected to multivariate analyses. A principal component analysis (PCA of the NMR data from the sugar beet leaves shows clear differences among the growth stages. At the later time points, the sugar and glycine betaine contents were increased, whereas the choline content was decreased. The relationship between the foliar metabolite profiles and resistance level to CLS was examined by combining partial least squares projection to latent structure (PLS or orthogonal PLS (OPLS analysis and univariate analyses. It was difficult to build a robust model for predicting precisely the disease severity indices (DSIs of each genotype; however, GABA and Gln differentiated susceptible genotypes (genotypes with weak resistance from resistant genotypes (genotypes with resistance greater than a moderate level before inoculation tests. The results suggested that breeders might exclude susceptible genotypes from breeding programs based on foliar metabolites profiled without inoculation tests, which require an enormous amount of time and effort.

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)

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

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 ( 3 H-fructose) 1'fluorosucrose ( 14 C-glucose) were applied at 10 mM ( 3 H/ 14 C=1) to an attached source leaf. After 6 h, sugars from plant parts in the translocation path were separated on HPLC. 14 C-1'fluorosucrose was translocated and accumulated in the root at a higher rate than 3 H-sucrose due to greater metabolism of 3 H-sucrose in the shoot (indicated by the presence of 3 H in hexose fractions and loss of asymmetry). In the root 25% of the 3 H-sucrose was hydrolyzed to hexoses whereas no 14 C 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

Full Text Available This study investigated the adsorption of cellulases onto sugar beet shreds. The experiments were carried out using untreated, as well as dried and not dried dilute acid and steam pretreated sugar beet shreds at different initial enzyme loads. Both dilute acid and steam pretreatment were beneficial in respect of cellulases adsorption providing 8 and 9 times higher amounts of adsorbed proteins, respectively, in comparison to the results obtained with the untreated substrate. Although the use of higher solids load enabled by drying of pretreated substrates, could be beneficial for process productivity, at the same time it decreases the adsorption of enzymes. The obtained experimental data were fitted to five adsorption models, and the Langmuir model having the lowest residual sum of squares was used for the determination of adsorption parameters which were used to calculate the strength of cellulases binding to the substrates.[Projekat Ministarstva nauke Republike Srbije, br.

Full Text Available Introduction The success of sugar beet as a crop depends on predictable seed germination, early seedling establishment and the rapid development of a leaf canopy which is able to utilize the available solar radiation efficiently. Seed priming has become a common practice to increase the rate and uniformity of field germination and emergence in many important crop plants in unfavorable conditions. Hydro-priming is a simple method of priming treatment that is used of distilled water as priming medium. Humic acid has been used for treatment before seed planting. Washing sugar beet seeds with water also affects the germination and seedling establishment through the elimination of inhibitory compounds on the seed coat. This study was conducted to evaluate the effect of seed priming with different methods at different times and concentrations on germination of sugar beet. Materials and Methods In the spring of 1393, a field trial was conducted simultaneously in two regions of the Jovain and Jajarm. The experimental was conducted as split plot (split-split plot in randomized complete block design with three replications.The main factor was irrigation with four levels of 100, 90, 80 and 70% water, sub-plots are including different methods of priming: control, priming with running water for 48 hours, priming with running water for 48 hours + Humic acid, priming with running water for 48 hours + Seed-start and priming with running water for 48 hours + Humic acid + Fulzym, sub-sub plots are including weeds competition with (absence and presence of weeds. Results and Discussion The results for two regions showed that by reducing the amount of irrigation water sugar beet root yield significantly reduced. Results show that the effect of priming treatment of running water for 48 hours + Seed-start and running water for 48 hours + Humic acid + Fulzym to have achieved the highest sugar beet root yield for two areas. The result of the interaction effect showed

Genomic information can be used to predict not only continuous but also categorical (e.g. binomial) traits. Several traits of interest in human medicine and agriculture present a discrete distribution of phenotypes (e.g. disease status). Root vigor in sugar beet (B. vulgaris) is an example of binomial trait of agronomic importance. In this paper, a panel of 192 SNPs (single nucleotide polymorphisms) was used to genotype 124 sugar beet individual plants from 18 lines, and to classify them as showing "high" or "low" root vigor. A threshold model was used to fit the relationship between binomial root vigor and SNP genotypes, through the matrix of genomic relationships between individuals in a genomic BLUP (G-BLUP) approach. From a 5-fold cross-validation scheme, 500 testing subsets were generated. The estimated average cross-validation error rate was 0.000731 (0.073%). Only 9 out of 12326 test observations (500 replicates for an average test set size of 24.65) were misclassified. The estimated prediction accuracy was quite high. Such accurate predictions may be related to the high estimated heritability for root vigor (0.783) and to the few genes with large effect underlying the trait. Despite the sparse SNP panel, there was sufficient within-scaffold LD where SNPs with large effect on root vigor were located to allow for genome-enabled predictions to work.

Full Text Available In this study, foliar sprays of Fenton solutions (Fenton reaction, Fenton-like reaction and Fenton complex, titanium dioxide (TiO2 and the recommended fungicide (chlorothalonil were estimated in the control of sugar beet leaf spot caused by Cercospora beticola under field conditions in two growing seasons. In addition, the impacts of these treatments on some crop characters (leaf dry weight, root fresh weight, soluble solid content, sucrose content and purity of sugar were examined. Biochemical and histological changes in the livers and kidneys of treated rats compared to an untreated control were utilized to assess the toxicity of the examined curative agents. Overall, chlorothalonil and Fenton complex were the most effective treatments for disease suppression in both tested seasons followed by Fenton-like reagent, Fenton’s reagent and TiO2, respectively. Growth and yield characters of treated sugar beet significantly increased in comparison to an untreated control. There were mild or no (biochemical and histological changes in the livers and kidneys of treated rats compared to the control. Fenton solutions and TiO2 may offer a new alternative for leaf spot control in sugar beet.

Soil compaction is a critical issue in agriculture having a significant influence on crop growth. Sugar beet (Beta vulgaris L.) is accounted as a crop susceptible to compaction. Reduction of leaf area, final yield, and root quality parameters are reported in compacted soils. The most obvious visual indicator of topsoil compaction is root depth affected by agricultural tractor and machinery traffic up on the soil. Such indicators are mainly correlated to initial soil condition, tyre features, and number of passages. Monitoring and controlling frequency and position of machine traffic across the field, in such a way that passages are completed on specific, well-defined tracks, can assist with minimization of compaction effects on soil. The objective of the present work was to analyze the subsoil compaction during the growing period of sugar beet with different farming approaches including controlled traffic passages and random traffic. To this end, tests were carried out following each agro technical operation using penetrometer readings in order to monitor the state of cone-index after each step. In addition, at the harvesting time, root quality parameters were analyzed with particular attention to length and regularity of the taproot, total length, circumference, mass, and above-ground biomass. Such parameters were usefully implemented in order to evaluate the effects of controlled traffic passages compared to the random traffic in a cultivation of sugar beet. Results highlight how an increase in crop yield, derived from samples monitored, higher than 10% can be expected with implementation of a careful traffic management.

Four Icelandic (ICE) and four Danish Warmblood (DW) horses were used in a crossover study with two treatments to investigate the effect of breed and the effect of stage of maturity of haylage on the apparent total tract digestibility (ATTD) of a diet consisting of sugar beet pulp, black oats and haylage early or late cut. Fibre was analysed as crude fibre (CF), acid detergent fibre (ADF), neutral detergent fibre (NDF) and dietary fibre (DF = non-starch polysaccharides (NSP) plus lignin). In haylage all analysed fibre fractions increased with advancing stage of maturity, with the cell wall components cellulose, non-cellulosic residue, xylose and lignin causing this increase. Crude protein (CP) and sugars decreased with advancing stage of maturity. Feeding early cut haylage resulted in a significantly (p haylage. There was a significantly (p haylage. Concentrations of total short-chain fatty acids were significantly (p haylage, reflecting the higher fermentability (higher ATTD) of this diet. There was no marked effect of breed on faecal parameters. The DF analysis method gave the most appropriate differentiation of the fibre fractions and their digestibility, compared to the traditional CF, ADF and NDF analyses. A major advantage of the DF analysis is the capacity of recovering soluble fibres. The results suggested that ICE had higher ATTD of DF than DW, and this was caused by a tendency for a higher ATTD of cellulose, but further studies are required to verify that in general.

Full Text Available The sustainability of soil resources is under significant threat due to the accelerated anthropogenic pressures at the historical expansion of human population. In this context, soil erosion is defined as a limiting factor for human interests in terms of ecosystem services. As an erosion type, harvest erosion occurs by harvesting of the taproot and tuberous root plants such as sugar beet (Beta vulgaris L., potato (Solanum tuberosum L., carrot (Daucus carota L. and chicory (Cichorium intybus L., has begun to take attention in recent years. The objective of this study was to estimate soil loss due to harvest erosion and to economically analyze the transport of plant nutrients between 1999 and 2016 from sugar beet growing areas in Turkey. For this aim, the compiled data of 25 different sugar factories throughout Turkey were obtained from Türkşeker and soil loss estimations were performed and economically analyzed. According to the results, average soil loss rate was calculated as 3.41 Mg ha-1y-1 for the studied period (1999-2016. That means annually an average of 716983 Mg soil removed from the Türkşeker sugar beet production areas. This result indicated that harvest erosion represents only 0.9% of soil lost by water erosion in Turkey. But, if tolerable soil loss value considered as “1 Mg ha-1 y-1”, calculated soil loss values are above this critical value for all the factories. In addition, economic assessments of soil losses showed that costs are to be more than US $10 000 annually on the 60% of the factories due to removal of plant nutrients with harvest process. And, annually US $419 433 investment must be made to recover all these losses. Conclusively, harvest erosion as an ignored erosion type must be emphasized to the economic sustainability of natural resources in fragile ecosystems such as our country.

Full Text Available The most effective safety management system of food production in all industrialized countries in the world recognized by the system based on the principles of HACCP. In Russia, the conformity assessment carried out by the HACCP system certification. The essence of the HACCP system is to identify and control the critical points. Critical Control Point – this is the stage of the process, which is subject to control for hazard identification and risk management in order to avoid the production of unsafe products. Implementation of HACCP system allows to tighten and coordinate the quality control system, which will improve the competitiveness of the products produced in the sugar market in Russia and abroad. In the early stages of food production HACCP system to prevent the occurrence of danger. It is based on the preventive approach to ensuring quality and safety in the production process, and can also be used in the development of new products. HACCP system is based on seven main principles to ensure the implementation and management of the system in production. 1. Creation of a working group of the coordinator and the technical secretary and various consultants. 2. Information on materials and products, in this case of sugar beet and sugar. 3. Information about the production. 4. Risk analysis of the available chemical, physical and microbiological factors. To determine the critical control points according to the results obtained for each factor is determined by a special chart the extent of its accounting. The need to consider the potential hazard is determined by the order in which area it has got. 5. The production program of mandatory preliminary activities in the production of sugar. 6. Determination of critical control points. 7. Making worksheets HACCP. It is shown that the use of HACCP in sugar beet production has several advantages.

Noninvasive presymptomatic detection of Cercospora beticola infection and identification of early metabolic responses in sugar beet

Directory of Open Access Journals (Sweden)

2016-09-01

Full Text Available Cercospora beticola is an economically significant fungal pathogen of sugar beet, and is the causative pathogen of Cercospora leaf spot. Selected host genotypes with contrasting degree of susceptibility to the disease have been exploited to characterize the patterns of metabolite responses to fungal infection, and to devise a pre-symptomatic, non-invasive method of detecting the presence of the pathogen. Sugar beet genotypes were analyzed for metabolite profiles and hyperspectral signatures. Correlation of data matrices from both approaches facilitated identification of candidates for metabolic markers. Hyperspectral imaging was highly predictive with a classification accuracy of 98.5-99.9 % in detecting C. beticola. Metabolite analysis revealed metabolites altered by the host as part of a successful defence response: these were L-DOPA, 12-hydroxyjasmonic acid 12-O-β-D-glucoside, pantothenic acid and 5-O-feruloylquinic acid. The accumulation of glucosylvitexin in the resistant cultivar suggests it acts as a constitutively-produced protectant. The study establishes a proof-of-concept for an unbiased, presymptomatic and non-invasive detection system for the presence of C. beticola. The test needs to be validated with a larger set of genotypes, to be scalable to the level of a crop improvement program, aiming to speed up the selection for resistant cultivars of sugar beet. Untargeted metabolic profiling is a valuable tool to identify metabolites which correlate with hyperspectral data.

Sporamin, a sweet potato tuberous storage protein, is a Kunitz-type trypsin inhibitor. Its capability of conferring insect-resistance on transgenic tobacco and cauliflower has been confirmed. To test its potential as an anti-feedant for the beet cyst nematode (Heterodera schachtii Schm.), the sporamin gene SpTI-1 was introduced into sugar beet (Beta vulgaris L.) by Agrobacterium rhizogenes-mediated transformation. Twelve different hairy root clones expressing sporamin were selected for studying nematode development. Of these, 8 hairy root clones were found to show significant efficiency in inhibiting the growth and development of the female nematodes whereas 4 root clones did not show any inhibitory effects even though the SpTI-1 gene was regularly expressed in all of the tested hairy roots as revealed by northern and western analyses. Inhibition of nematode development correlated with trypsin inhibitor activity but not with the amount of sporamin expressed in hairy roots. These data demonstrate that the trypsin inhibitor activity is the critical factor for inhibiting growth and development of cyst nematodes in sugar beet hairy roots expressing the sporamin gene. Hence, the sweet potato sporamin can be used as a new and effective anti-feedant for controlling cyst nematodes offering an alternative strategy for establishing nematode resistance in crops.

2017-08-01

On-demand electricity generation can be achieved by just-in-time biogas production instantly utilized in co-generation units. For this goal, easily degradable substrates like sugar beet silage have a high potential. Potential for on-demand biogas production from co-digestion of sugar beet silage (SS) with grass silage (GS) was evaluated in two experiments at organic loading rates (OLRs) of 1.5 kgVS m -3 day -1 and 2.5 kgVS m -3 day -1 , respectively. Each experiment was fed with intermittent feeding system at 8 hrs interval at the same feedstock ratios (volatile solids based) of GS:SS-1:0, 3:1 and 1:3, respectively. Modelling by Gaussian equation was performed in order to understand the effects of SS on biogas production. Addition of sugar beet silage led to maximum biogas production within a short time, but it differed significantly depending on feedstock ratios and OLRs, respectively. At OLR 1.5 kgVS m -3 day -1 , during mono fermentation of grass silage maximum biogas production rate of 0.27 l N hr -1 was reached at 2.74 hrs. Production rate did not change at feedstock ratio of GS:SS-3:1 but increased to 0.64 l N hr -1 at GS:SS-1:3 within a shorter time span (1.58 hrs). On the contrary, at OLR of 2.5 kgVS m -3 day -1 time span between feedstock input and maximum biogas production did not differ significantly (p > 0.05) among the reactors. Biogas production rates were 0.60 l N hr -1 within 2.27 hrs and 0.82 l N hr -1 within 2.30 hrs at GS:SS-3:1 and GS:SS-1:3, respectively. Surprisingly, there was no time lag between maximum biogas and methane production rates, irrespectively of OLR. This implies that once the whole microbial community is adapted to intermittent substrate input, the metabolic products are instantly utilized through the all steps of anaerobic substrate degradation. Applying this finding opens new perspectives for on-demand biogas energy production. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available A field experiment was performed to determine the effects of using humic acid with irrigation on quantitative and qualitative yield traits of sugar beet grown on calcareous soils in Esfaraen, located in the North-East of Iran. Treatments consisted of three levels of humic acid concentration (zero or control, 2.5 and 5 L ha-1 and the number of applications (once 45 days after planting; twice, 45 and 75 days after planting; three times, respectively 45, 75 and 105 days after planting. The effect of the two experimental factors on sugar beet yield traits such as the content of sucrose, refined sugar, molasses forming substances, root yield and refined sugar yield were evaluated. The results proved the existence of a significant interaction between humic acid concentration and the number of applications on all parameters under study. The application of humic acid caused a significant increase of sucrose, refined sugar, root yield and refined sugar yield and a reduction in molasses forming substances content, compared to the control. The increased amount of sucrose and refined sugar content in all applications in concentration of 2.5 L ha-1 humic acid was more than with 5 L ha-1. Similarly, the content of molasses forming substances showed more reduction in 2.5 L ha-1 than in 5 L ha-1 treatment. However, the results revealed that the highest root yield and refined sugar yield, as the main qualitative and quantitative parameters of sugar beet yield, were achieved by three times application of 5 L ha-1 that had 24 and 37% increase compared to control.

We tested on 40 beet samples how far it might be possible to assess beet quality using refractometric and densimetric methods. Regarding the parameter molasses non-sugar on beet, a combination of Aluminum defecation and refractometry proved to be almost equivalent to methods based on non-sugar components. As well as for thick juice purity and molasses non-sugar on beet, formulae are given, assuming low Ca molasses, for molasses sugar and corrected sugar, respectively, on beet. By assuming a relative loss between beet and thick juice, very simple relationships were found. Practical tests in beet laboratories have not yet been carried out. (orig.)

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 o 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.

Full Text Available Abstract Beet stillage is a high-strength effluent from the production of ethanol from sugar beet. A large annual volume of sugar beet stillage requires finding new effective ways for its utilization. The aim of the study was to investigate the effect of temperature on the efficiency of aerobic biodegradation of beet stillage. Biodegradation was carried out for 168 hours in a stirred-tank reactor with a working volume of 5 L at 27°C, 36°C, 45°C, 54°C and 63°C. All experiments were performed at uncontrolled pH, aeration of 1.0 vvm and of 900 rpm. The effectiveness of biodegradation was determined by the extent of removal of SCODsum (COD determined after suspended solids separation and theoretical COD of betaine, BOD5 and TOC. Studies have shown that, under mesophilic conditions, the extents of reduction of SCODsum, BOD5 and TOC were statistically significantly (p≤0.05 higher than under thermophilic conditions. Within the range of 27-36°C, the highest reduction in SCODsum (79.2-79.9%, BOD5 (98.4-99% and TOC (76.1-77.3% was obtained. Additionally, at the temperature of 36°C, the highest reduction in total nitrogen (56.4% and total phosphorus (58% was achieved. Aerobic biodegradation allows for efficient treatment of sugar beet distillery stillage (preferably at 36°C.

Full Text Available The effects of pressed beet pulp silage (PBPS replacing barley for 10% and 20% (DM basis were studied on heavy pigs fed dairy whey-diluted diets. 60 Hypor pigs (average initial weight of 28 kg, 30 barrows and 30 gilts, were homogeneously allocated to three exper- imental groups: T1 (control in which pigs were fed a traditional sweet whey- diluted diet (the ratio between whey and dry matter was 4.5/1; T2 in which PBPS replaced barley for 10% (DM basis during a first period (from the beginning to the 133rd day of trial and thereafter for 20% (DM basis; T3 in which PBPS replaced barley for 20% (DM basis throughout the experimental period. In diets T2 and T3 feed was dairy whey-diluted as in group T1. No significant (P>0.05 differences were observed concerning growth parameters (ADG and FCR. Pigs on diets contain- ing PBPS showed significantly higher (P<0.05 percentages of lean cuts and lower percentages of fat cuts. On the whole, ham weight losses during seasoning were moderate but significantly (P<0.05 more marked for PBPS-fed pigs as a prob- able consequence of their lower adiposity degree. Fatty acid composition of ham fat was unaffected by diets. With regard to m. Semimembranosus colour, pigs receiving PBPS showed lower (P<0.05 “L”, “a” and “Chroma” values. From an economical point of view it can be concluded that the use of PBPS (partially replacing barley and dairy whey in heavy pig production could be of particular interest in areas where both these by products are readily available.

2007-01-01

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 W I , N I I 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 N I I 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 N I and N I I treatments, but it was higher in case of N I 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

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 M/sub 4/ 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.

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.

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.

2015-12-01

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.

Ralet, Marie-Christine; Crépeau, Marie-Jeanne; Bonnin, Estelle

2008-06-01

Commercial acid-extracted sugar beet pectin was extensively hydrolysed using an endo-polygalacturonase (AnPGI from Aspergillus niger or AnPGII from A. niger or FmPG from Fusarium moniliforme) in combination with Aspergillus aculeatus pectin methyl-esterase (AaPME). The homogalacturonan-derived oligogalacturonates released were quantified by high-performance anion-exchange chromatography and their structure determined by mass spectrometry. The different endo-polygalacturonases exhibited variable tolerance towards acetyl groups. AnPGI was the most active and FmPG the less. A hypothetical homogalacturonan was constructed using the AnPGI-recovered oligogalacturonates as building blocks and the validity of the model was checked taking into account FmPG observed requirements and hydrolysis products. A blockwise repartition of the acetyl groups onto sugar beet pectin homogalacturonan is proposed.

Full Text Available Experiments were carried out at El-Riad district, Kafr El-Sheikh Governorate in two successive growing seasons (2009/10 and 2010/11 to study the effect of intercropping of faba bean, maize and cabbage with sugar beet on the population density of Empoasca spp. (nymphs and adults, Aphis spp. (nymphs and adults, Bemisia tabaci (adults, Pegomyia mixta (eggs and larvae, Cassida vittata (larvae, pupae and adults and predators in sugar beet plantations compared with the non-intercropped plants and the resulting yield. The toxicity of certain compounds: fenitrothion, super misrona, sour orange oil, acidless orange oil, and Bermectine in reducing the population density of P. mixta and C. vittata larvae infesting sugar beet was evaluated. The rate of infestation was higher in the sole sugar beet plants than in those intercropped with faba bean, maize and cabbage plants which caused reduction of sucking pests and P. mixta eggs in the two seasons. The intercropping of faba bean plants led to higher infestation rate of P. mixta larvae in the two seasons and C. vittata (larvae, pupae and adults in the first season. The intercropping with maize led to a higher population density of Chrysoperla carnea, Paederus alfierii and Scymnus spp. in the two seasons. Low population density of true spiders was observed in sole sugar beet (control when compared with faba bean, maize and cabbage plants intercropped in the two seasons. Concerning the obtained root yield, the intercropping with maize and cabbage plants reduced the resultant yield of sugar beet roots in the two seasons. Bermectine and fenitrothion were the most effective toxicants followed by super misrona and then, sour orange that induced the lowest reduction in P. mixta larvae. Also, fenitrothion and Bermectine were the most potent compounds in reducing the population density of C. vittata larvae followed by super misrona and then, plant oil extracts.

Metal interrelationships in plant nutrition. I. Effects of some metal toxicities on sugar beet, tomato, oat, potato, and Marrowstem kale grown in sand culture

Energy Technology Data Exchange (ETDEWEB)

Hewitt, E J

1953-02-01

Sugar beet, tomato, potato, oat, and kale were grown in sand cultures with additions of several heavy metals including Cr, Mn, Co, Ni, Cu, Zn, Pb, Cd, V, Mo, in equivalent concentrations. In sugar beet Cu/sup + +/, Co/sup + +/, Cd/sup + +/ were usually highly active in causing chlorosis mainly suggestive of iron deficiency. The effect of Cr depended on valency and was greater as CrO/sub 4//sup - -/, Zn/sup + +/, VO/sub 3//sup - -/, Cr/sup + + +/, Mn/sup + +/, and Pb/sup + +/ were less active in order. The visual responses to Co/sup + +/ and Ni/sup + +/ varied greatly with the crop tested. Cu/sup + +/, however, always induced typical iron deficiency. Crop susceptibility also varied greatly. For example, Cu/sup + +/ readily caused chlorosis in beet and also in tomato, and potato, but not in oat and kale. Ni/sup + +/ induced symptoms resembling manganese deficiency in potato and tomato and unusual oblique white and green banding leaves of oat. Zn/sup + +/ induced apparent manganese deficiency in sugar beet and Co/sup + +/ toxicity in tomato initially resembled manganese deficiency. Ni/sup + +/ and Co/sup + +/ were the most toxic of the metals tested.

2017-10-01

Owing to the changing climate, narrow crop rotation, and changes in insecticide application practice, sugar beet weevil (SBW) (Bothynoderes punctiventris Germar) has become the most important economic pest in sugar beet. To develop alternative control methods, an area-wide (AW) control program using aggregation pheromones was implemented over 4 years on an area of 6 and 14.8 km 2 in east Croatia. The mass trapping of SBW on the 'old' sugar beet fields reduced the population from 0.73% to 11.59%. Owing to the strong attack, mass trapping was not effective enough to avoid an insecticide application. However, it significantly reduced the number of insecticide applications, the amount of insecticide used, and the damage compared to the fields outside the mass trapping area. This is the first study to implement an AW program for SBW. It may not be possible to state from this study that trapping alone can reduce the SBW population below the economic threshold level. However, the data do suggest that trapping can play an important role in the reduction of insecticide applications and in creating an integrated pest management plan for dealing with SBW under similar circumstances. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Flexible biorefinery for producing fermentation sugars, lignin and pulp from corn stover.

Kadam, Kiran L; Chin, Chim Y; Brown, Lawrence W

2008-05-01

A new biorefining process is presented that embodies green processing and sustainable development. In the spirit of a true biorefinery, the objective is to convert agricultural residues and other biomass feedstocks into value-added products such as fuel ethanol, dissolving pulp, and lignin for resin production. The continuous biomass fractionation process yields a liquid stream rich in hemicellulosic sugars, a lignin-rich liquid stream, and a solid cellulose stream. This paper generally discusses potential applications of the three streams and specifically provides results on the evaluation of the cellulose stream from corn stover as a source of fermentation sugars and specialty pulp. Enzymatic hydrolysis of this relatively pure cellulose stream requires significantly lower enzyme loadings because of minimal enzyme deactivation from nonspecific binding to lignin. A correlation was shown to exist between lignin removal efficiency and enzymatic digestibility. The cellulose produced was also demonstrated to be a suitable replacement for hardwood pulp, especially in the top ply of a linerboard. Also, the relatively pure nature of the cellulose renders it suitable as raw material for making dissolving pulp. This pulping approach has significantly smaller environmental footprint compared to the industry-standard kraft process because no sulfur- or chlorine-containing compounds are used. Although this option needs some minimal post-processing, it produces a higher value commodity than ethanol and, unlike ethanol, does not need extensive processing such as hydrolysis or fermentation. Potential use of low-molecular weight lignin as a raw material for wood adhesive production is discussed as well as its use as cement and feed binder. As a baseline application the hemicellulosic sugars captured in the hydrolyzate liquor can be used to produce ethanol, but potential utilization of xylose for xylitol fermentation is also feasible. Markets and values of these applications are

Influence of passion fruit albedo, citric acid, and the pulp/sugar ratio on the quality of banana preserves

2012-06-01

Full Text Available The objective of this research was to evaluate the effect of the citric acid concentration, pulp/sugar ratio, and albedo concentration of the passion fruit peel on physical, physiochemical, and sensorial characteristics of the 'Silver' banana preserves. A 2³ factorial design and 3 repetitions in the central point were used. The albedo concentration between 0 and 3% had significant influence on the reduction of the reducing sugars and on the decrease in titratable acidity. The increase in the pulp/sugar ratio exerted a negative effect on the pH and positive on the titratable acidity; the acid addition reduced the non-reducing sugar level. The sensorial evaluation and purchase intention indicated that the incorporation of a maximum of 1.5% albedo in formulations containing 50% pulp and 0.5% citric acid resulted in products with good acceptability in comparison with the formulation in which 60% pulp and an absence of acid or albedo is utilized.

1994-01-01

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

Phloem unloading in developing leaves of sugar beet

International Nuclear Information System (INIS)

Schmalstig, J.G.

1985-01-01

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 [ 14 C]-sucrose added to the free space of developing leaves, but did not affect import of [ 14 C]-sucrose during steady-state 14 CO 2 labeling of a source leaf. The passively-transported xenobiotic sugar, [ 14 C]-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, [ 14 C]-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 14 CO 2 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 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 To evaluate sugar-beet genotypes for their trait associations, two separate RCBD experiments with three replications were conducted both under non-saline (normal and saline conditions at the Agricultural Research of Miandoab. Analysis of variance of the data collected showed that there were significant differences among genotypes for all traits studied under non-saline condition. But, differences of genotypes under saline condition were significant only for root yield, root potassium content, sugar extraction coefficient, impure and pure (white sugar yields. Salinity stress, in this study, reduced root potassium content, root yield, sugar extraction coefficient, impure and pure (white sugar yields. Mean comparisons of genotypes indicated that root yield of all genotypes, under non-saline condition, were higher than those of under saline one. As whole, genotypes number 1 and 2 produced higher root yields, impure and pure sugar yields respectively, under both saline and non-saline conditions. Based on the results obtained it was revealed that regression coefficients for the traits under study were significant. Step-wise regression and path coefficient analyses also indicated that traits like root yield, pure sugar and root nitrogen contents highly affected white sugar yield under non-saline conditions.

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.

Full Text Available This study was carried out in the General Commission for Scientific Agricultural Research (GCSAR, Syria, at Der EzZour Agricultural Research Center, from 2008-2010, to examine the effect of salt conditions on some growth attributes and chlorophyll fluorescence in 10 Sugar Beet (Beta vulgaris L. genotypes under salinity stress. Sugar beet plants were irrigated with saline water, having electrical conductivity ranged from 8.6-10 dS.m-1during first year and 8.4-10.4 dS.m-1 during second year. A randomized completely block design with three replicates was used. The results showed that all studied growth attributes, leaf area, leaf number, relative growth rate, and net assimilation rate were decreased in salinity stress conditions compared to the controlled state. The findings indicated that salinity caused a decrement of light utilizing through increased values of fluorescence origin (fo, decreased values of fluorescence maximum (fm, and maximum yield of quantum in photosystem-II (fv/fm. Genotypes differed significantly in all studied attributes except in leaf number. Under salt conditions, Brigitta (monogerm achieved an increase in net assimilation rate, while Kawimera (multigerm achieved the lowest decrement in quantum yield in photosystem-II. Further studies are necessary to correlate the yield with yield components under similar conditions to determine the most tolerant genotype.International Journal of Environment Vol.3(1 2014: 1-9 DOI: http://dx.doi.org/10.3126/ije.v3i1.9937

Panagopoulos, I.; Bornman, J.F.; Björn, L.O.

1992-01-01

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

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.

1993-01-01

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

In a field experiment Sugar beet Beta vulgaris was grown as a spring crop during the growing seasons of 2004 and 2006, in salt affected soil, previously planted with sesbania and barley (2005 and 2003) to evaluate the response of sugar beet to two irrigation methods, (drip fertigation and surface irrigation), different levels of nitrogen fertilizer and its effect on yield and quality. Different rates of nitrogen fertilizers (0, 50, 100, 150 and 200 kg N/ ha) as urea (46% N) were injected for drip irrigation or broadcasted for the surface-irrigated treatments in four equally split applications. The 15 N labelled urea was applied to sub-plots of 1.0 m 2 in each experimental unit in a manner similar to that of unlabeled urea. Irrigation scheduling was carried out using the direct method of neutron scattering technique. Sugar beet was irrigated when soil moisture in the upper 25 cm was 80% of the field capacity (FC) and such practice continued until the six leaf stage. From the latter stage until harvest, sugar beet was irrigated when soil moisture in the upper 50 cm reached 80% of the FC. The amount of irrigation water applied, electrical conductivity of the soil paste, dry matter and fresh roots yield, total nitrogen uptake and N derived from fertilizer were also determined. Furthermore, Nitrogen use as well as water use-efficiencies for dry matter and roots yield were also calculated. Results revealed that sugar beets and dry matter yield increased with increasing N input up to 100-150 kg N/ha which was indicated by the higher dry matter yield, and sugar beet yield. Sugar percentage was also increased relative to the average percentage recorded in Syria. Crop water use efficiencies, for both the drip-fertigated and surface-irrigated treatments were increased in most cases with increasing rate of nitrogen fertilizer. During the course of this study, small increases in soil salinity under both irrigation methods were observed. Higher increases in soil salinity was

Two triploid hybrids, widespread in sugarbeet production, were sown as standards – Os Sana and Iva. The trials were conducted on two localities (Osijek and Đakovo during the two years (2002 and 2003. There was a difference between years in weather conditions and between localities in terms of type and features of soil. First year of the investigation was humid and warm and the second was dry and hot. Osijek locality was characterized by chernozem-meadow type soil and Đakovo by loessial pseudoglei. The best average root yield was achieved between the investigated genotypes by the triploid hybrid 15 (58.09 t/ha and the hybrids 11, 13 and standard 31. As for the content and utilization of sugar, the standard 31 achieved best results (15.15% followed by the standard hybrids 15, 18, 17 and 11. The best sugar yield was achieved by hybrid 15 (7.08 t/ha, followed by hybrids 13, 11, 10 and 18.

The effects of high Zn concentration were investigated in sugar beet (Beta vulgaris L.) plants grown in a controlled environment in hydroponics. High concentrations of Zn sulphate in the nutrient solution (50, 100 and 300 microm) decreased root and shoot fresh and dry mass, and increased root/shoot ratios, when compared to control conditions (1.2 microm Zn). Plants grown with excess Zn had inward-rolled leaf edges and a damaged and brownish root system, with short lateral roots. High Zn decreased N, Mg, K and Mn concentrations in all plant parts, whereas P and Ca concentrations increased, but only in shoots. Leaves of plants treated with 50 and 100 microm Zn developed symptoms of Fe deficiency, including decreases in Fe, chlorophyll and carotenoid concentrations, increases in carotenoid/chlorophyll and chlorophyll a/b ratios and de-epoxidation of violaxanthin cycle pigments. Plants grown with 300 microm Zn had decreased photosystem II efficiency and further growth decreases but did not have leaf Fe deficiency symptoms. Leaf Zn concentrations of plants grown with excess Zn were high but fairly constant (230-260 microg.g(-1) dry weight), whereas total Zn uptake per plant decreased markedly with high Zn supply. These data indicate that sugar beet could be a good model to investigate Zn homeostasis mechanisms in plants, but is not an efficient species for Zn phytoremediation.

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.

Full Text Available Response surface methodology (RSM was used for selecting optimal fermentation time and initial sugar mass fraction in cultivation media based on raw juice from sugar beet in order to produce ethanol. Optimal fermentation time and initial sugar mass fraction for ethanol production in batch fermentation by free Saccharomyces cerevisiae cells under anaerobic conditions at the temperature of 30 °C and agitation rate of 200 rpm were estimated to be 38 h and 12.30 % by mass, respectively. For selecting optimal conditions for industrial application, further techno-economic analysis should be performed by using the obtained mathematical representation of the process (second degree polynomial model. The overall fermentation productivity of five different types of yeast was examined and there is no significant statistical difference between them.

Influence of frequent magnetic field on chlorophyll content in leaves of sugar beet plants

Rochalska, M.

2005-01-01

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)

Full Text Available The effect of defoliation on root yield and quality of suagrbeet (Beta vulgaris L. was examined in a field study in Research Station of Faculty of Agriculture, Ferdowsi University of Mashhd during 2005 growing season. The experiment was conducted as a split plot on the basis of randomized complete block design with three replications.Time of Defoliation (May 16th, May 31th, June 18th, July 9th, July 31th, and August 20th were allocated to main plots and defoliation severity (0, 30, 60, and 100% were assigned to subplots. Results showed that root yield, shoot and root dry weight and sugar yield were influenced by defoliation time. However, defoliation time had no significant effects on sugar white content and white sugar yield. Effects of defoliation on plant growth was more pronounced in mid season when about 1500 degree days was accumulated, compared to early or late season. Defoliation intensity resulted in a significant decrease in root yield, shoot fresh weigth, root and shoot dry weight, sugar and white sugar content, and white sugar yield compared with undefoliated control, but molass sugar was increased in all defoliation intensities. sugar and white suagr percent were significantly affected by defoliation time x intensity interaction. Complete defoliation (100% on July 30th and Auguat 19th led to 18 and 21% reduction in sugar and 29 and 28% in white suagar, respectively. However, 100% defoliation in July 8th resulted in 6 and 8% increase in sugar and white sugar, respectively. Keywords: Time of defoliation, defoliation intensity, sugarbeet yield,sugar beet quality.

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

2011-01-01

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.

Full Text Available Food products from vegetable raw materials play a special role in the food industry. Sugar is one of the strategically important products. The significance of its is great due to its wide use in confectionery, bakery, liquor, canning, biochemical, pharmaceutical and other branches of human activity. Effective development of the domestic sugar industry depends on the terms of competition with European partners. Production of granulated sugar includes a significant amount of energy-intensive and technologically complex operations, one of which is the extraction of sucrose from beet chips by means of hot countercurrent extraction. The most important criterion for the extraction process efficiency evaluation is the coefficient of molecular diffusion. The efficiency of using of beet chips thermo chemical processing before extraction depending on the quality of processed beet was investigated. It was found out that when using a low quality beet the diffusion coefficient decreases compared to healthy beet. The use of solutio ns of some salts for beet chips heat treatment has an overall positive effect on the diffusion coefficient. A method for recovering sucrose from beet with the use of compounds of Al2(SO4, Ca(SO4, and (NH42SO4 as the extractants was proposed. It was found out that beet samples treatment with solutions of proposed salts provides a sucrose smooth transition from the pores of sugar beet tissue into the extractant due to intense convective washout. It is caused by the high degree of tissue cells plasmolysis achieved in its processing with solutions of proposed reagents. The results obtained indicate a significant increase of the sucrose diffusion coefficient in the ammonium sulfate solution used as the extractant.

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

Directory of Open Access Journals (Sweden)

Kuljanin Tatjana A.

2013-01-01

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

The batch fermentation process of sugar beet processing intermediates by free yeast cells is the most widely used method in the Autonomous Province of Vojvodina for producing ethanol as fuel. In this study a process and cost model was developed for producing ethanol from raw juice. The model can be used to calculate capital investment costs, unit production costs and operating costs for a plant producing 44 million l of 99.6% pure ethanol annually. In the sensitivity analysis the influence of sugar beet and yeast price, as well as the influence of recycled biomass on process economics, ethanol production costs and project feasibility was examined. The results of this study clearly demonstrate that the raw material costs have a significant influence on the expenses for producing ethanol. Also, the optimal percentage of recycled biomass turned out to be in the range from 50% to 70%. Copyright © 2011 Elsevier Ltd. All rights reserved.

Full Text Available Effect of Organic Manure on Sugar Beet Cyst Nematode Population Densities of Heterodera schachtii Schmidt 1871 Introduction. Sugar beet cyst nematode (SBCN, Hederodera schachtii Schmidt. 1871, marked as one of the most damaging disease of sugar beet worldwide. It's also an important disease of sugar beet in Isfahan Province, and causing plenty of an irreversible damage. Thus, the nematode infested fields for cultivation in the province and the country is to be threatened. This nematode has a wide host range, over 218 plant species from 95 genera, belonging to 23 families, including field crops, ornamentals and weeds as hosts, which have been identified and introduced so far. The SBCN management's strategies are a long term crop rotation, use of catch crops, early planting and the use of nematicides. In general, the best method reported to control SBCN is a 3 to 7-year rotation with non-host plants. In addition, incorporation of farm manure into the soil had a positive effect in controlling potato golden cyst nematode. Testing on vermicomposting and non-organic fertilizers revealed that, free-living nematodes in the population index were highest in the vermicompost treatments than non-organic fertilizers. Materials and methods. The initial population of SBCN in the infested soil was determined, before the treatment of the selected field. Then, 200 g. of soil were selected, out of several samples collected from every plots, which was air dried and in the file system using Fenwick, the cysts were extracted.

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.

ROW METHOD OF SUGAR BEET (BETA VULGARIS L. FERTILIZATION WITH MULTICOMPONENT FERTILIZER BASED ON UREA-AMMONIUM NITRATE SOLUTION AS A WAY TO INCREASE NITROGEN EFFICIENCY

Directory of Open Access Journals (Sweden)

Przemysław BARŁÓG

2010-12-01

Full Text Available Sugar beet is the main crop commonly cultivated for sugar production in temperate regions of the World. Actual yields in main Central Europe producing countries are much lower, due to many limiting factors. Among them, nutrients supply is of great value, especially referring to efficiency of nitrogen, which is generally low. In the conducted study two methods of nitrogen application were compared (i broadcast of calcium saltpeter and (ii row application of the multicomponent fertilizer based on urea-ammonium-nitrate (UAN solution. The basic amount of the applied N was 75 kg ha-1. The highest yields of both taproots and refined sugar were harvested on the plot receiving 75 kg N-1 as UAN liquid multicomponent fertilizer and 50% of the recommended P and K rates. The positive effects of row application of liquid N fertilizer on taproot and sugar yields were also corroborated by high values of indices of agronomic efficiency for both N as well as P and K. However this method of sugar beets fertilization has some possibilities, as indicated by still high contents of melassogenic substances.

Full Text Available Conservative agriculture and nitrogen fertilisation have been evaluated for the purpose of assessing their impact on the sustainability of a cropping system based on a two-year rotation with two crops considered for the bio-ethanol supply chain: sugar beet (Beta vulgaris L. subsp. vulgaris and sweet sorghum (Sorghum bicolor L. Moench. The experimental activity started in 2009 in Foggia (Apulia, southern Italy. We discuss the results obtained in the 2010-2011 period. Soil minimum tillage (MT vs no tillage (NT combined with two doses of nitrogen fertilisation (75 and 150 kg ha–1 of mineral nitrogen as ammonium nitrate were compared. The experimental system, which is still operational (soil tillage plus nitrogen fertilisation, was arranged with a split-plot design with three replicates. Treatments were applied on the same plots every year with both crops present at the same time. At the first harvest in 2010, no difference was observed. As to the second year, the comparison between NT vs MT treatments showed that sugar beet had lower total yield (35 vs 42 t ha–1, dry biomass (10 vs 14 t ha–1, and sucrose yield (6.7 vs 8.2 t ha–1. Total soluble solids, on average 19%, were not influenced by the experimental treatments. Nitrogen (N control was less productive than the fertilised treatments (average between N75 and N150 in terms of total fresh root yield (32 vs 42 t ha–1, dry biomass (10 vs 14 t ha–1, and sucrose yield (6.0 vs 8.1 t ha–1. As with sugar beet, during the second year, also sweet sorghum sown in NT vs MT plots had a reduced yield, although the difference was more marked for fresh biomass (–35% than for dry biomass (–20%. No interaction in terms of soil tillage nitrogen fertilisation occurred. In summary, in the first two-year period (2010-2011 of the experimental trial, no tillage soil management showed decreased yields of both crops. Sugar beet displayed a higher sensitivity to the lack of nitrogen supply than sweet

Samples containing two viruses belonging to the genus Polerovirus, beet chlorosis virus (BChV) and beet mild yellowing virus (BMYV), were collected from French and Polish sugar beet fields. The molecular properties of 24 isolates of BChV and BMYV were investigated, and their genetic diversity was examined in the coat protein (CP)- and P0-encoding genes. For the first time, we have demonstrated that beet polerovirus populations include recombinants between BChV and BMYV containing breakpoints within the CP gene. Moreover, a partial correlation between geographic origin and phylogenetic clustering was observed for BMYV isolates.

Quaternary IPM (integrated pest management)--concept for the control of powdery mildew in sugar beets.

Wolf, P F J; Verreet, A

2008-01-01

Powdery mildew, caused by Erysiphe betae (Vanha) Weltzien, may be assumed as an important leaf disease in sugar beet growing areas of central Europe. Although the causal agent is mainly adapted to arid climatic zones, the disease is appearing every year, where the extent of infection is mainly dependent on weather conditions and susceptibility of cultivar. The losses caused by powdery mildew seldom exceed 10% of sugar yield; moreover, losses are likely only under the condition that the epidemic onset occurs before end-August. Nevertheless, the epidemic onset varies in a wide range, as there are years with high incidence followed by growing periods without severe infection. Therefore, in order to have a flexible control of the disease, where the use of fungicides could be minimised to an essential amount, a quaternary IPM (Integrated Pest Management) -concept was developed. The development is based on epidemiological field studies (Germany, 1993-2004, n = 76) of sugar beet leaf diseases under variation of year, site and cultivar. Efficacy of fungicide treatment timing was assessed in relation to the epidemic development. Comparison of treatments comprised fungicide sprays carried out from disease initiation till later stages of the epidemic. Additionally, the assessments were performed in relation to an untreated and a healthy control--the latter was three times treated according to a treatment regime with three to four week intervals. The effect of different application timings was measured by the potential of disease and yield loss control. The quaternary concept combines the advantages of four elements in order to compensate the constraints of the single tools: The period without disease risk is determined by a so-called negative-prognosis (i). First symptoms appear in the period from mid-July till the beginning of September. If disease initiation cannot be excluded, field observations by a sample of 100 leaves are advised. The disease scores enable the appliance

In the study, single factors and their impact on sugar beet cultivation against the background of past and projected climate change are being analyzed. The database consists of climate data by the German Weather Service and 1x1 km interpolated INTERMET raster data. Impact models were run to assess possible future trends using climate projection data of the REgional MOdel (REMO), emission scenario A1B, Run 1, data stream 2 for Germany, daily resolution, without bias correction, 10x10 km raster (n=150) (MPI on behalf of UBA 2006). Compared periods were: B:1971 2000; K:2021-2050; L:2071-2100. Agronomic data were collected from the field books of regional trials from 1974 2014 (n=448). Moreover, a business survey of regional farmers was carried out and evaluated. Impact models to predict timing for sowing, the date of field emergence and row closure, were derived from these data. The ontogenesis was simulated using a linear, temperature-based leaf-growth model. Sowing shifted forward by 7,3 days in regional field trials from 1974 2014. Progress-oriented, risk-tolerant farmers start sowing 10-14 days earlier compared to 1980. Recently, sowing is being conducted on average on 21 March in southwest Germany. For period K, 17 March, and for period L, 2 March is being projected as the average future sowing date while the same late frost risk applies compared to present climatic conditions. Shifting forward the sowing date with spring warming and, thus, exploiting the associated yield potential is the most promising agronomic adaptation strategy to the projected climate change on the farm level. In connection to earlier sowing, the field emergence tendentially shifted forward by 14 days in the field trials. Assuming sowing on 15 March, projection results show an advance of field emergence form 7 April in period B to 3 April in period L. Row closure in field trials in average shifted forward by 19,6 days. For period L, 29 May and thus, an earlier row closure of 9 days compared

Waste from pulp and paper mills consist of sugar-rich fractions comprising hemicellulose derivatives and cellulose by-products. A complete characterisation of the waste streams is necessary to study the possibilities of an existing mill. In this work, four chromatographic methods have been developed to obtain the most suitable chromatographic method conditions for measuring woody feedstocks, lignocellulosic hydrolysates and cellulose pulp in sulphite pulping processes. The analysis of major and minor monosaccharides, aliphatic carboxylic acids and furfurals has been optimised. An important drawback of the spent liquors generated after sulphite pulping is their acidic nature, high viscosity and adhesive properties that interfere in the column lifetime. This work recommends both a CHO-782Pb column for the sugar analysis and an SH-1011 resin-based cross-linked gel column to separate low-molecular-weight chain acids, alcohols and furfurals. Such columns resulted in a good separation with long lifetime, wide pH operating range and low fouling issues.

Evaluation of the fermentation of high gravity thick sugar beet juice worts for efficient bioethanol production

Science.gov (United States)

2013-01-01

Background Sugar beet and intermediates of sugar beet processing are considered to be very attractive feedstock for ethanol production due to their content of fermentable sugars. In particular, the processing of the intermediates into ethanol is considerably facilitated because it does not require pretreatment or enzymatic treatment in contrast to production from starch raw materials. Moreover, the advantage of thick juice is high solid substance and saccharose content which eliminates problems with the storability of this feedstock. Results The objective of this study were to investigate bioethanol production from thick juice worts and the effects of their concentration, the type of mineral supplement, as well as the dose of yeast inoculum on fermentation dynamics and ethanol yield. The obtained results show that to ensure efficient ethanolic fermentation of high gravity thick juice worts, one needs to use a yeast strain with high ethanol tolerance and a large amount of inoculum. The highest ethanol yield (94.9 ± 2.8% of the theoretical yield) and sugars intake of 96.5 ± 2.9% were obtained after the fermentation of wort with an extract content of 250 g/kg supplemented with diammonium hydrogen phosphate (0.3 g/L of wort) and inoculated with 2 g of Ethanol Red dry yeast per L of wort. An increase in extract content in the fermentation medium from 250 g/L to 280 g/kg resulted in decreased efficiency of the process. Also the distillates originating from worts with an extract content of 250 g/kg were characterized by lower acetaldehyde concentration than those obtained from worts with an extract content of 280 g/kg. Conclusions Under the favorable conditions determined in our experiments, 38.9 ± 1.2 L of 100% (v/v) ethyl alcohol can be produced from 100 kg of thick juice. The obtained results show that the selection of process conditions and the yeast for the fermentation of worts with a higher sugar content can improve the economic performance of the

Full Text Available Historical data were used to determine if the warm springs experienced in recent decades have influenced time of sowing of spring cereals (barley, wheat and oats, potato and sugar beet in Finland. The start of the thermal growing season was used to represent all climatic factors affecting sowing time. Regional anomalies in sowing and start of growing season were computed for the years 1965–2007. The start of the growing season was 2–2.8 days earlier per decade, with a steeper increase since 1980. Sugar beet sowing advanced 2.5 (since 1980 5.2 and potato planting 3.4 (since 1980 4.5 days per decade, more than expected solely due to earlier starts to the growing season. Sowing of spring cereals advanced 0.6, 0.7 and 1.7 days per decade in the east, north and west respectively (since 1980 1.0, 1.9 and 3.1, with statistically significant trend (p < 0.01 in the west. Earlier sowings can be largely explained by warmer springs, but the trend was not as steep as that for the growing season. This has however not led to increased temperatures during early vegetative phases and thus faster development and increased drought or pest risk, which would have reduced the positive effects of earlier sowing on yield potential. Earlier sowing detected in the west can be explained by changes in spring temperatures, but may also result from economic and technological development. Farmers seem to have adequately adjusted their field activities to the changes in spring temperatures.;

1990-02-01

A computer program has been developed in order to simulate the energy consumption of beet sugar factories, for various plant configurations. The program is divided into five block units: Extraction and Juice purification, Juice concentration, Crystallization, Drying and finally the Power House. Each block consists of different modules, for example, a heat exchanger, an evaporator, a turbine and a dryer. The purpose of this project was to simulate some different system configurations of a sugar factory, whereby both new and previously used process technologies were utilized. The following parts of the process have been particularly emphasized: Power House - gas turbine, waste heat boiler. Drying - low-temperature dryer, steam dryer. Evaporation - vapour recompression. Crystallization - vapour recompression, continuous system. The different plant configurations have been compared to a reference factory, which is designed according to current technology used in a modern and well balanced Swedish factory. The comparisons are based upon the total power consumption as well as the total annual energy costs. Eleven different plant configurations were studied. The maximum power reduction is 36%, relative to the reference factory. The dissertation also contains an experimental study of a low-temperature drying process. The drying characteristics of pressed beet pulp were studied in a specially designed rotary dryer pilot plant. A number of parameters were varied i.e. the solid moisture content, air velocity, temperature and rotational speed. The results are given in terms of an apparent volumetric heat-transfer coefficient, determined from measured data. A mathematical model was established to determine the residence time of the material in the rotary dryer at different air velocities. (45 refs.).

Cercospora leaf spot (CLS) epidemics in sugar beet have been increasing in recent years causing higher use of fungicides. Concomitantly, the availability of effective fungicides is at risk because of resistance development in the fungus, the lack of new active ingredients as well as restrictive approval practices. A key option for an integrated management of CLS is cultivation of resistant varieties. Because of the yield penalty in resistant varieties, acceptance in commercial practice so far has been low. The aim of our study was to characterize recent sugar beet varieties registered in Germany in terms of resistance and tolerance to CLS and their value for integrated pest management. The genetic basis of CLS resistance in varieties is protected by intellectual property rights even after variety registration and not open to the public due to economic competition. To gain reliable data for cultivation, varieties have to be tested for their resistance traits under field conditions at varying levels of infection with Cercospora beticola . In collaboration with variety related stakeholders, 15 sugar beet varieties were tested in 49 field trials in Germany from 2014 to 2016 for their yield response to CLS. The trials were set up in a split-plot design with and without infection (i.e., with and without fungicide). The classification of varietal reaction to CLS is based on symptomatic leaf area (susceptibility) and the resulting relative yield loss (tolerance). Since the relation between both parameters varied among varieties, it was used as an additional parameter to describe tolerance. On this basis, three groups of varieties were identified. They can be characterized as a susceptible, a resistant and a presumably tolerant cluster. A comparison of the data with an older dataset originating from 2009 to 2011 revealed that yield performance of recent varieties with resistance to C. beticola caught up with susceptible varieties due to breeding progress. They showed no

Possibility of partial replacement of flour by beet-sugar molasses (I) in acetone-BuOH fermentation was investigated on a commercial scale. Detailed regimes of experiments carried out in two trials were given. Yields of fermentation (kg/1000 kg starch of mash) were: 125.3, 214.4, and 31.5 of acetone, BuOH and EtOH, respectively, for pure flour-mash; 123.3, 215.3, and 28.7 of acetone, BuOH, and EtOH, respectively, at 10% flour replaced by I; 127.8, 205.9, and 51.8, respectively, at 50% flour replaced by I; and 120.17, 216.48, and 42.3, respectively, at 62% flour replaced by I. Inoculum, grown in the seed-mash containing flour only, was not mixed with fermentor-mash until the stage of acid production by the inoculum was reached. During the fermentation of mashes in which 62% flour was replaced by I, a slight foaming was observed.

THE FACTORS FORMING QUALITY OF GRANULATED SUGAR

Full Text Available Sugar, with good taste and high caloric, is one of the most popular human food. Consumers sugar must be sure that the sugar under normal conditions of use is of high quality and is not harmful to the health of the product. One reason for the decline in the quality of sugar is bacterial contamination. This is because the sugar industry products are good targets for the development of different groups of microorganisms, e.g., Bacillus subtilis, Clostridium perfringes, Leuconostoc dextranicum, Torula alba, Pseudomonas fluorescens, Sarcina lutea and others. These organisms are affected with beets, and then with sugar beet chips and diffusion juice fall into the processing line of sugar production. Their number in the diffusion juice varies and depends on many facto rs such as the quality of raw materials, the quality of cleaning beet root colonization of transporter-washing and the supply of water to the diffusion process, the temperature of the diffusion and others. In the diffusion unit has the most favorable conditions for the development of micro-organisms. Some of them, especially resistant bacteria and thermophilic bacteria or their spores, forming a capsule which protects against external influences occur in the final product sugar. When injected into the fresh crop of product (juice, syrup, they begin to multiply rapidly, causing difficulties in the process. The higher seeding beet microorganisms, the more they decompose and emit sucrose metabolism byproducts. To reduce the negative impact of microbiological and reduce losses from decomposition of sucrose conducted research on the possibility of using chlorine-containing substances in the sugar industry. It was established experimentally that the investigated chlorinated drug has bacteriostatic action and can be recommended for use in sugar beet production.

Full Text Available Field studies were carried out in 1989–1995 and 2006–2012 on plantations of sugar beet (Beta vulgaris L. subsp. vulgaris. During this period, 542 phytosociological relevés were made using the Braun-Blanquet method. In total, 46 weed species were found. In 1989–1995, the occurrence of 36 segetal species was reported. The highest cover indices were determined for Chenopodium album and Amaranthus retroflexus. Galium aparine, Echinochloa crus-galli, and Elymus repens were the dominant species, as well. Analysis of the frequency of occurrence revealed one constant species (Chenopodium album, two frequent species (Amaranthus retroflexus and Galium aparine, and two medium-frequent species (Echinochloa crus-galli and Matricaria maritima ssp. inodora. In 2006–2012, the occurrence of 40 weed species on the sugar beet plantations was recorded. The plantations were clearly dominated by Chenopodium album, accompanied by Polygonum persicaria and Polygonum lapathifolium ssp. lapathifolium. Other dominant species comprised Setaria viridis, Galinsoga parviflora, Brassica napus ssp. napus, and Fallopia convolvulus. The Chenopodium album was a constant component of the sugar beet plantations. In turn, no frequent species were observed and six medium-frequent species were found (Setaria viridis, Galinsoga parviflora, Brassica napus ssp. napus, Echinochloa crus-galli, Amaranthus retroflexus, and Capsella bursa-pastoris. Noteworthy, the presence of previously unreported species, e.g., Abutilon theophrasti, Hyoscyamus niger, or Artemisia vulgaris, was revealed. These species are rare components in sugar beet crops. A reverse phenomenon, i.e., the disappearance of some species such as Euphorbia helioscopia, Malva neglecta, Rumex acetosella, Sinapis arvensis, or Sisymbrium officinale, was also observed.

Shcherbakov Vladimir Ivanovich

Full Text Available Water management in sugar factories doesn’t have analogues in its complexity among food industry enterprises. Water intensity of sugar production is very high. Circulation water, condensed water, pulp press water and others are used in technological processes. Water plays the main role in physical, chemical, thermotechnical processes of beet processing and sugar production. As a consequence of accession of Russia to the WTO the technical requirements for production processes are changing. The enforcements of ecological services to balance scheme of water consumption and water disposal increased. The reduction of fresh water expenditure is one of the main tasks in economy of sugar industry. The substantial role in fresh water expenditure is played by efficiency of cooling and aeration processes of conditionally clean waters of the 1st category. The article contains an observation of the technologies of the available solutions and recommendations for improving and upgrading the existing recycling water-cooling systems of sugar mills. The authors present the block diagram of the water sector of a sugar mill and a method of calculating the optimal constructive and technological parameters of cooling devices. Water cooling towers enhanced design and upgrades are offered.

Cold-inhibited phloem translocation in sugar beet

International Nuclear Information System (INIS)

Grusak, M.A.

1985-01-01

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 [ 14 C]-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 1 0 C (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 Powdery mildew, caused by Erysiphe betae is a major foliar disease of sugar beet in areas with dry and relatively warm weather conditions throughout the world. In the present study, four fungicides belonging to the relatively new class of strobilurin fungicides, azoxystrobin, kresoxim-methyl pyraclostrobin and trifloxystrobin were evaluated in three different application doses (100, 150 and 200 mg a.i. ha–1 during 2003-2004 for the control of the disease. Among the four strobilurin fungicides tested trifloxystrobin and kresoxim-methyl were the most effective with control efficiency values higher than 94% compared to the control treatment even when applied at lower application dose of 100 mg a.i. ha–1. Azoxystrobin and pyraclostrobin showed a poor to modest activity against the disease even when applied at the highest application dose of 200 μg a.i. ha–1. Disease severity, in terms of AUDPC values was significantly correlated to decreased root yield, while no significant correlation existed among disease severity and sugar content of the roots or sucrose yield. In addition, the efficiency of tank mixtures of four strobilurin fungicides applied at 100 μg a.i. ha–1 with two sterol demethylation - inhibiting fungicides (DMIs, difenoconazole and cyproconazole applied at 62.5 and 25 mg a.i. ha–1, respectively, was evaluated. The mixtures of azoxystrobin and pyraclostrobin with either difenoconazole or cyproconazole provided a better control efficiency compared to the single application of each mixture partner, while the tank mixtures of trifloxystrobin and kresoxim-methyl with either difenoconazole or cyproconazole provided a better control efficiency compared to single application of difenoconazole or cyproconazole and similar control efficiency compared to the efficiency obtained by single application of the strobilurin fungicides.

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.

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.

Full Text Available In many crops, incorrect management of nitrogen and water is one of the most important factors in the resources productivity such as water and nitrogen. In order to evaluate the effects of different nitrogen levels (zero, 50, 100 and 150 kg ha-1 and irrigation application rates (100, 75 and 50% of water requirement per species on corn, sesame and sugar beet, three separate experiments was conducted in Agricultural Research Station of Ferdowsi University of Mashhad, Iran, in 2009-2010 growing season. Three separate experiments were arranged by strip plots in randomized complete block design, with three replications. The results showed that effect of irrigation application rates on biological yield and grain number per ear and interaction effects of water × nitrogen on plant height, 100 grain weight and grain yield of corn was significant. With decreasing irrigation over 25 % water requirements, the highest grain yield (4.93 ton ha-1 in corn observed by applying nitrogen equal to 50 kg.ha-1. In addition, the highest maize yield (9.41 ton.ha-1 in mentioned was obtained by supplying 100 % water requirements. Effects of Irrigation levels on plant height and the interaction effects of water × nitrogen on 1000 grain weight in sesame was significant. Under no water stress, the highest grain yield (1.22 ton ha-1 in sesame was obtained with applying 50kg nitrogen per ha. With supplying 75% water requirements plus 50 kg nitrogen per hactar, maximum yield of sesame (820 kg ha-1 was obtained. Results of this study indicated that interaction between studied factors had insignificant effect on economic and biological yield in sugar beet. With supplying 25% water requirements plus 50 kg nitrogen per ha, maximum yield of sugar beet (58.37 ton ha-1 was achieved. It seems that suitable nitrogen management can be considered as approach in optimize the water consuming.

2018-04-01

Four kinds of bleached, unbleached, second and third crystal sugars (BCS, UCS, SCS and TCS) were made from different massecuites in a sugar-beet factory, and their physiochemical (polarization, invert sugar, colorants, pH, ash and SO 2 ), microbiological and functional properties were measured. While the polarization of UCS, SCS and TCS were lower than BCS; their invert sucrose, colorants, pH and ash contents were significantly higher than BCS. The phenols and betaine of BCS, UCS, SCS, and TCS were 144, 401, 384 and 673 (mg/100 g); and 244, 791, 4662, and 6589 (mg/100 g); respectively. Whereas the phenol of milk chocolate bars (MCB) made with UCS, SCS, and TCS were only 10% higher than MCB completed with BCS; their betaine contents were substantially (up to 16 times) higher than the ones finished with BCS. Sensory evaluation showed that the MCB prepared with three sugars including UCS, SCS and TCS had significantly higher glossiness, brittleness, flavor and mouth feel than those made with BCS. The greater colorants, ash content and inverted sugars of UCS, SCS and TCS (in comparison with BCS) made considerable improvements in the glossiness, flavor and brittleness of MCB, respectively. BCS had 8 ppm of toxic sulfur; whereas, UCS, SCS and TCS had no detectable sulfur and significantly higher beneficial copper content than BCS. No pathogenic microorganism were detected in UCS, SCS, TCS or their subsequent MCB. Our results highly recommend using UCS, SCS and TCS instead of BCS in food products (such as MCB) due to their higher health benefits.

IMPACT OF FURFURAL ON THE SUGAR ANALYSIS OF PRE-HYDROLYSIS LIQUOR OF KRAFT-BASED DISSOLVING PULP PRODUCTION PROCESS USING THE HPAEC TECHNIQUE

Directory of Open Access Journals (Sweden)

Abrar Saeed

2011-03-01

Full Text Available High performance anion-exchange chromatography with pulse ampero-metric detector (HPAEC-PAD is a reliable method to systematically determine the sugar contents in pulp and paper waste streams, including bleaching and extraction liquors. We used the same method to determine the sugar content of industrially produced pre-hydrolysis liquor (PHL from a kraft-based dissolving pulp production process. The analysis showed that the traditional method cannot be applied for sugar analysis, and an improvement on the method was required. In fact, the presence of furfural in the PHL sample was the reason for the required modification. It was noted that the removal of furfural via evaporation could improve the reliability of the HPAEC technique for sugar assessments. If the concentration of furfural was higher than 0.045% (wt. in the PHL, the error introduced in the sugar analysis was profound. Also, the industrially produced PHL contained more furfural than the laboratory produced PHL under the same hydrolysis conditions. Consequently, the concentration of furfural in the PHL should be taken into account for sugar analysis using the HPAEC technique.

In conventional alcohol fermentation processes using yeast species, the substrate cost represents a major fraction of the total production cost. Therefore, it may be very attractive to use the bacterium Zymomonas mobilis, since it has shown higher ethanol yields than yeasts when grown on a glucose-based medium. A report is made on the use of mutant strain of Zymomonas mobilis for ethanol production from hydrolyzed sugar beet molasses in a two-stage continuous culture which showed high ethanol yield and an ethanol concentration sufficiently high for economical recovery. A single stage continuous culture was first operated in an attempt to reduce the formation of sorbitol. Further on, a second fermentor was added with additional substrate feeding to increase the effluent ethanol concentration. An ethanol concentration of 59.9g/l was obtained at 97% sugar conversion and at high ethanol yield. The volumetric ethanol productivity was superior to that of batch fermentation but inferior to that of a single-stage continuous system with the same medium. However, the ethanol concentration was increased to a level acceptable for economical recovery. 18 refs., 3 figs., 5 tabs.

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 m 2 ) 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 [fr

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

International Nuclear Information System (INIS)

Shieh, Wenjang; Geiger, D.R.

1990-01-01

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 14 CO 2 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 14 C 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

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.

This study investigated the effects of beet sugar (BS), calcium lactate (CL), and Staphylococcus xylosus (SX) on the general characteristics of uncured frankfurters. Minimum residual nitrite was observed in samples with a high level of BS and S. xylosus (8log(10) l0 viable cfu/g) after 2 mo. There was an increase in total aerobic counts in frankfurters after 4 wk. Samples containing higher BS and CL had no Clostridium perfringens at storage time. Histamine content was similar for all treatments except SX. No differences were observed in textural properties among the treatments. Water activity was decreased significantly in treatment CL1+BS2. The results indicated that samples treated with BS or CL had (P meat products in many countries. Health problems (such as cancer) associated with the overconsumption of cured meat have led to searches for new, alternative methods of preservation. Hurdle technology (combinations of beet sugar, calcium lactate, and Staphylococcus xylosus in different concentrations) can be developed for frankfurter processing. Results of this research will be useful for meat manufacturers; however, any new process may affect the strategies chosen for marketing these products. © 2012 Institute of Food Technologists®

2013-02-13

The study investigates the complexes formed between sodium caseinate (SC) and sugar beet pectin (SBP) and to harness them to stabilize SBP emulsions. We find that both hydrophobic and electrostatic interactions are involved in the complexation. In SC/SBP mixed solution, soluble SC/SBP complexes first form on acidification and then aggregate into insoluble complexes, which disassociate into soluble polymers upon further decreasing pH. The critical pH's for the formation of soluble and insoluble complexes and disappearance of insoluble complexes are designated as pH(c), pH(φ), and pH(d), respectively. These critical pH values define four regions in the phase diagram of complexation, and SC/SBP emulsions were prepared in these regions. The results show that the stability of SBP-stabilized emulsion is greatly improved at low SC/SBP ratios and acidic pH's. This enhancement can be attributed to an increase in the amount of adsorbed SBP as a result of cooperative adsorption to sodium caseinate. Using a low ratio of SC/SBP ensured that all caseinate molecules are completely covered by adsorbed SBP chains, which eliminates possible instability induced by thermal aggregation of caseinate molecules resulting from stress acceleration at elevated temperatures. A mechanistic model for the behavior is proposed.

The objective of this study was to develop a method for the thermally-assisted acidic hydrolysis of waste biomass from the sugar industry (sugar beet pulp and leaves) for chemical and biotechnological purposes. The distillates, containing furfural, can be catalytically reduced directly into furfurayl alcohol or tetrahydrofurfuryl alcohol. The sugars present in the hydrolysates can be converted by lactic bacteria into lactic acid, which, by catalytic reduction, leads to propylene glycol. The sugars may also be utilized by microorganisms in the process of cell proliferation, and the biomass obtained used as a protein supplement in animal feed. Our study also considered the effects of the mode and length of preservation (fresh, ensilage, and drying) on the yields of furfural and monosaccharides. The yield of furfural in the distillates was measured using gas chromatography with flame ionization detector (GC-FID). The content of monosaccharides in the hydrolysates was measured spectrophotometrically using enzymatic kits. Biomass preserved under all tested conditions produced high yields of furfural, comparable to those for fresh material. Long-term storage of ensiled waste biomass did not result in loss of furfural productivity. However, there were significant reductions in the amounts of monosaccharides in the hydrolysates.

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

Changes in acidification, proteolysis, sugars and free fatty acids (FFAs) concentrations of Ghanaian cocoa beans as affected by pulp preconditioning (pod storage or PS) and fermentation were investigated. Non-volatile acidity, pH, proteolysis, sugars (total, reducing and non-reducing) and FFAs concentrations were analysed using standard methods. Increasing PS consistently decreased the non-volatile acidity with concomitant increase in pH during fermentation of the beans. Fermentation decreased the pH of the unstored beans from 6.7 to 4.9 within the first 4 days and then increased slightly again to 5.3 by the sixth day. Protein, total sugars and non-reducing sugars decreased significantly (p cocoa beans was largely affected by fermentation than by PS.

Development of base populations from root and tuber crops for the production of sugar and starch as raw material for the industry

Frese, L.; Schittenhelm, S.; Dambroth, M.

1987-01-01

Based on results of evaluation and breeding programmes with beets, potato, Jerusalem artichoke and chicory the following conclusions can be drawn: For breeding beets with a high sugar yield it seems favourable to produce hybrids between sugar and fodder beet. Compared to the average of their parents the sugar beet x fodder beet and fodder beet x sugar beet hybrids produced 3,8 and 12,9% resp., higher sugar yields. It is, however, from this experiment not fully clear if heterosis allone is the explanation for this increase. Several preselected populations of the primitive potato species S. tuberosum subsp. andigena and S. phureja from the United States, Scotland and the Netherlands have been tested in a field trial. Compared to Phureja the Andigena material has reached a high level of adaptation. An immediate use in commercial breeding programmes for the production of high yielding Tuberosum-Andigena hybrids is possible. In Jerusalem artichoke the production of new genetic variability by crossing is complicated by the bad fertility of this species. Because of the very limited breeding activities in the past a large advance is possible. Even though the species C. intybus is of many shapes, only the root chicory is suitable for use as an industrial crop.

Sugar beets were gradually fertilized with 15 N-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

Full Text Available Abstract The aim of this study was to evaluate in sherbet formation the effects of sugar, milk, and jambolan pulp quantity on the overrun, color, physicochemical characteristics, microbiological characteristics, and acceptance of the experimental sherbets, in addition to evaluating the bioactive compounds of the selected product. Seven formulations were established through the Simplex method. The formulation with 20g 100g-1 sugar, 45g 100g-1 milk, and 35g 100g-1 jambolan pulp was selected (S5 because it was included among the most accepted sensorially (S4 and S5, and also presented higher overrun, chroma, SST/AT, and pH than S4, receiving the scores 8.0; 8.2, 6.4 and 7.1 and 6.1, respectively, for appearance, color, flavor, texture, and odor. The selected sherbet presented a high total phenolic compound content of 192mg gallic acid g-1, and a percentage of DPPH inhibition of 73%. It is concluded that it is possible to produce jambolan sherbet with desirable physical, chemical, microbiological, and sensory characteristics, which can increase the possibilities of applying the fruit as an ingredient in the edible ice cream industry.

Aspergillus niger produces an arsenal of extracellular enzymes that allow synergistic degradation of plant biomass found in its environment. Pectin is a heteropolymer abundantly present in the primary cell wall of plants. The complex structure of pectin requires multiple enzymes to act together. Production of pectinolytic enzymes in A. niger is highly regulated, which allows flexible and efficient capture of nutrients. So far, three transcriptional activators have been linked to regulation of pectin degradation in A. niger. The L-rhamnose-responsive regulator RhaR controls the production of enzymes that degrade rhamnogalacturonan-I. The L-arabinose-responsive regulator AraR controls the production of enzymes that decompose the arabinan and arabinogalactan side chains of rhamnogalacturonan-II. The D-galacturonic acid-responsive regulator GaaR controls the production of enzymes that act on the polygalacturonic acid backbone of pectin. This project aims to better understand how RhaR, AraR and GaaR co-regulate pectin degradation. For that reason, we constructed single, double and triple disruptant strains of these regulators and analyzed their growth phenotype and pectinolytic gene expression in A. niger grown on sugar beet pectin.

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.

Full Text Available The exact and reliable detection of sugar monomers and fructans provides important information for the evaluation of carbohydrate metabolism in plants and animals. Using the HPLC method; a large number of samples and single sugars; with both high sensitivity and selectivity; may be analysed. It was shown that the described method—using a Nucleosil column loaded with Pb2+ ions; a refractive index detector (RID; and HPLC-grade water as the eluent—gives precise and reproducible results regarding the detection of individual sugars in extracts of plants and feed materials. The method can be applied for the detection of sucrose; maltose; lactose; xylose; glucose; galactose; arabinose; fructose; ribose; and mannitol. Furthermore; depending on the plant material; the sugars verbascose; stachyose; and raffinose can be separated. The peaks were well resolved and the reproducibility of the analysis; with 94–108% of recovery (RC and relative standard deviation (RSD of up to 5%; was very good. The method was successfully applied to a variety of green forages and samples of sugar beet pulp silages. It is also possible to determine fructan with inulin as a standard; together with the other sugars; or alone by a different protocol and column.

2014-06-01

Full Text Available Soluble fibre (SF is an important nutrient to enhance fermentative activity and gut health in rabbits. The main source of SF in rabbit diets is sugar beet pulp (SBP, whereas, due to its high content of SF (34%, dried chicory pulp (ChP could be an alternative to SBP. In a fattening trial with 192 hybrid weanlings 32 d old weighing 837±45 g, chicory pulp was used in replacement of SBP to study effects on production performances and slaughter characteristics. Rabbits were fed one of 4 iso-energetic (9.65 MJ digestible energy/kg and isonitrogenous (15.6% crude protein diets: a negative control (NC diet with a low dietary SF content (7.3%, a positive control diet with quite a high SBP level (13.5% and SF content (10.6% and 2 diets with respectively 10% and 20% of chicory pulp (ChP10: 9.9% SF and ChP20: 13.7% SF. The SF content was measured as the difference between total dietary fibre and neutral detergent fibre, the latter corrected for ash and protein content. Each dietary treatment consisted of 12 replicates of 4 rabbits. Weight gain was high (on av. 54 g/d and comparable for the NC, SBP and ChP diets. However, feed conversion ratio was improved (P<0.05 with the ChP20 diet compared to the NC diet (2.88 vs. 2.97. Mortality was low and not influenced by the dietary treatment. Slaughter data were very similar and no effect of the SF level on caecal weight or slaughter yield was observed. It was concluded that chicory pulp is a good alternative soluble fibre source in balanced diets for rabbits and can be used at least up to 20% inclusion rate.

Full Text Available The aim of this work was to improve the quality of gluten-free bread made with high content of soy flour and enriched with sugar beet molasses by incorporating ingredients with a potential to simultaneously enhance the nutritional quality of the breads. The following ingredients were used: pea protein isolate, pea fibre and chia seeds. The chosen ingredients exerted positive effects on bread quality. They promoted volume increase and crumb softening. In this respect, the most effective ingredients were pea protein isolate (at 1% supplementation level, pea fibre (at up to 2% supplementation level and chia seeds (at 1% supplementation level. The sensory analysis revealed that pea fibre and chia addition at 1 and 2% supplementation level provided bread with higher scores regarding overall acceptance, crumb texture and taste. At 1% supplementation level, there was not found statistically significant difference in sensory attributes of bread supplemented with pea protein isolate in comparison to the control. However, pea protein isolate was found to strongly diminish bread taste at 4% supplementation level due to presence of beany taste.

2012-01-01

The conversion of two agricultural wastes, sugar beet pulp and peanut hulls, into sustainable activated carbons is presented and their potential application for the treatment of arsenate solution is investigated. A direct and physical activation is selected as well as a simple chemical treatment of the adsorbents. The material properties, such as BET surface areas, porous volumes, elemental analysis, ash contents and pH(PZC), of these alternative carbonaceous porous materials are determined and compared with a commercial granular activated carbon. An adsorption study based on experimental kinetic and equilibrium data is conducted in a batch reactor and completed by the use of different models (intraparticle diffusion, pseudo-second-order, Langmuir and Freundlich) and by isotherms carried out in natural waters. It is thus demonstrated that sugar beet pulp and peanut hulls are good precursors to obtain activated carbons for arsenate removal.

1980-01-01

The sugar contents in undiluted molasses were found to be stable on γ-irradiation. The contents of total sugar and direct reducing sugar in cane molasses were completely unaffected by irradiation with doses of less than 3 Mrad. The reduction of total sugar content in beet molasses was 2% at 3 Mrad. On the other hand, in the molasses diluted with water, sugar contents decreased with the dose. Sucrose in molasses was degraded by irradiation, and subsequently glucose and fructose were formed. Raffinose in beet molasses was also degraded by irradiation, but galactose could not be detected. The irradiation temperature ranging from room temperature to 61 0 C, was hardly responsible for the change of sugar contents, but the changes in sugar caused by irradiation were enhanced at pHs of less than 4 and with an excess of oxygen.

Full Text Available The mathematical model describing distribution of fields of temperatures and moisture contents in a particle of a squared beet press at convective drying is given. As the initial equations the differential equations of material and thermal balances in which transfer of warmth and weight is caused by phase transformations have been accepted. The algorithm of the numerical solution of a non-stationary regional problem of heat conductivity with variable heat and mass transfer coefficients of the dried-up product, boundary and entry conditions and also phase transition with mobile limit of the section of phases is developed for the solution of mathematical model. At the same time the initial system of the equations is given to a dimensionless look. For the solution of a problem of non-stationary heat conductivity the zone method of calculation of temperature fields when drying a beet press is used. Process of drying broke into some time intervals. Within each interval geometrical form of a particle, its density, heatphysical and mass-exchanged characteristics; initial distribution of temperature and moisture content on particle volume and also density of a mass and thermal stream with the evaporated moisture are constant. The zone method of the solution of a problem of the non-stationary three-dimensional equation of heat conductivity for a parallelepiped taking into account internal sources of warmth has been checked on experimental data of stationary drying of a beet press with use of basic data. For realization of a zone method dependences of change of the linear size of a particle of a beet press on spatial coordinate x and its moisture content in the course of drying are received. At constant values of moisture content and the sizes of the party of the dried-up particle on each step the method of a machine experiment has found the current values of coefficient of phase transformation on condition of the maximum rapprochement of settlement and

Full Text Available Abstract Background It is known that large dogs who are fed lamb and rice diets are at increased risk to develop taurine-deficiency-induced dilated cardiomyopathy. Since dogs obligatorily conjugate bile acids (BA with taurine, we determined whether rice bran (RB or other fibers (cellulose; CL, beet pulp; BP would affect BA excretion and/or the taurine status of dogs. Results Eighteen medium/large mixed-breed dogs were given purified diets containing CL, BP, or RB for 12 weeks. Taurine concentrations in plasma and whole blood were significantly decreased at week 12. The BP group, compared to the CL or RB groups, showed significantly lower taurine concentrations in plasma (6.5 ± 0.5 vs 20.4 ± 3.9 and 13.1 ± 2.0 μmol/L, respectively, P < 0.01, mean ± SEM and in whole blood (79 ± 10 vs 143 ± 14 and 127 ± 14 μmol/L, respectively, P < 0.01, lower apparent protein digestibility (81.9 ± 0.6 vs 88.8 ± 0.6 and 88.1 ± 1.2 %, respectively, P < 0.01, and higher BA excretions (5.6 ± 0.1 vs 3.4 ± 0.5 and 3.4 ± 0.4 μmol/g feces, respectively, P < 0.05 at week 12. Conclusions These results do not support the hypothesis that RB is likely to be a primary cause of lamb meal and rice diets, increasing the risk of taurine deficiency in large dogs. However these indicate that BP may contribute to a decrease taurine status in dogs by increasing excretion of fecal BA and decreasing protein digestibility, thus decreasing the bioavailability of sulfur amino acids, the precursors of taurine.

Putnik-Delić Marina I.

2010-01-01

Full Text Available Eleven sugar beet genotypes were tested for their capacity to tolerate drought. Plants were grown in semi-controlled conditions, in the greenhouse, and watered daily. After 90 days, water deficit was imposed by the cessation of watering, while the control plants continued to be watered up to 80% of FWC. Five days later concentration of free proline in leaves was determined. Analysis was done in three replications. Statistical analysis was performed using STATISTICA 9.0, Minitab 15, and R2.11.1. Differences between genotypes were statistically processed by Duncan test. Because of nonormality of the data distribution and heterogeneity of variances in different groups, two types of transformations of row data were applied. For this type of data more appropriate in eliminating nonormality was Johnson transformation, as opposed to Box-Cox. Based on the both transformations it may be concluded that in all genotypes except for 10, concentration of free proline differs significantly between treatment (drought and the control.

This work investigated the improvement of ethanol production by engineered ethanologenic Escherichia coli to express the hemoglobin from the bacterium Vitreoscilla (VHb). Ethanologenic E. coli strain FBR5 and FBR5 transformed with the VHb gene in two constructs (strains TS3 and TS4) were grown in cheese whey (CW) medium at small and large scales, at both high and low aeration, or with whey powder (WP) or sugar beet molasses hydrolysate (SBMH) media at large scale and low aeration. Culture pH, cell growth, VHb levels, and ethanol production were evaluated after 48 h. VHb expression in TS3 and TS4 enhanced their ethanol production in CW (21-419%), in WP (17-362%), or in SBMH (48-118%) media. This work extends the findings that "VHb technology" may be useful for improving the production of ethanol from waste and byproducts of various sources.

When ethanol is produced using beet molasses, the concentration of ethanol is lower than that obtained using suger cane molasses. Yeast strain improvement was conducted to enhance ethanol production from beet molasses. The procedures and the results are as follows: (1) After giving ethanol tolerance to the flocculent yeast, strain 180 and the killer yeast, strain 909-1, strain 180-A-7, and strain 909-1-A-4 were isolated. These ethanol tolerant strains had better alcoholic fermentation capability and had more surviving cells in mash in the later process of fermentation than the parental strains. (2) Strain H-1 was bred by spore to cell mating between these two ethanol tolerant strains. Strain H-1 is both flocculent and killer and has better alcoholic fermentation capability than the parental strains. (3) In the fermentation test of beet molasses, strain H-1 showed 12.8% of alcoholic fermentation capability. It is equal to that of sugar cane molasses. Fermentation with reused cells were also successful. (5 figs, 21 refs)

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.

Konservierung von Zuckerrüben zur Substratversorgung von Biogasanlagen – Verlauf der Silierung und Verluste bei 12 Sorten

Full Text Available Due to the criticism of the intensive cultivation of maize in Germany as well as the problem of more frequently occurring pests in crop rotation sugar beet has been used successfully as a substrate for biogas plants in recent years. Varieties with a high sugar yield proved to be particularly suitable. However, sugar beet has to be conserved and stored in order to integrate it into the process of biogas production throughout the entire year. Neither the success of conservation nor potential losses over the storage period have been documented so far. Batch tests have been used to investigate the course of conservation, watching the pH value and the losses while ensiling twelve different sugar beet varieties. The sugar beets were ensilaged as pulp under anaerobic conditions in a fourfold repetition for 90 days. In all variants, an almost parallel development of the pH value was observed. Although there were significant differences between the pH values of the different variants all pH values were sufficiently low to ensure safe conservation. Losses of methane forming potential after 90 days of storage fluctuated between approximately 10 and 20%. Alcoholic fermentation was identified as the reason for these losses. The results show that ensiling of different sugar beet varieties can be achieved quickly and safely. Also, alcoholic fermentation after acidification of the silage leads to considerable fluctuations in the level of losses, both the dry substance and the methane forming potential.

Full Text Available Cooking of massecuites has been study in the connection with different particle size distribution of white sugar. During the crystallization is possible to operate with parameters which have influence on particle size of white sugar. Dry matter of juice in crystallizer, volume of the standard syrup in crystallizer and heating curve of crystallization process are constant parameters in this process. Quantity of slurry (seed magma crystallizate and volume of slurry massecuite are parameters which can be changed for control the particle size distribution of white sugar. Five variants of viable parameters have been trying for obtain ideal particle size distribution of white sugar. As a best has been evaluated variant with 1100 cm3 of slurry and 20 % of volume of slurry massecuite in crystallizer. This variant has had the crystals proportions captured by the sieves between 1.00 and 0.40 mm with minimal differences in weight. More results have been related to reduction of losses of sugar in molasses with the right setting for the line of cooling crystallization process. The looses of sugar can be reduced by adding two coolers in the end of cooling crystalization process what will decrease a temperature to 40 ° C. This temperature will lead to more efficient crystallization in the cooling crystallization process.doi:10.5219/122

Full Text Available The objective of the pot trial carried out at the area of the Slovak University of Agriculture in Nitra was to determine the impact of dry pig manure produced on the sawdust bedding and sawdust litter on the level of nutrients’ mobility in the soil and sugar beet yield. The achieved results showed that one month after the sawdust and manure application to the soil, the contents of mobile nutrients (Nan, P, K, Ca, Mg in soil were lower than in the control unfertilized treatment. The sawdust litter immobilized nutrients more considerably than manure. Four months after the manure application into soil, its immobilization effect was not evident. On the contrary, the manure increased the mobile nutrients content in soil. In the second year of experiment the immobilization effect of sawdust litter was proved even four months after its application into soil. The application of manure increased considerably the beet root yield. The maximum root yield was determined in the treatment where the highest dose of manure was applied. The minimum root yield was detected in the treatment where the highest dose of sawdust litter was applied.

Hydrogen was produced from carrot pulp hydrolysate, untreated carrot pulp and (mixtures of) glucose and fructose by the extreme thermophiles Caldicellulosiruptor saccharolyticus and Thermotoga neapolitana in pH-controlled bioreactors. Carrot pulp hydrolysate was obtained after enzymatic hydrolysis of the polysaccharide fraction in carrot pulp. The main sugars in the hydrolysate were glucose, fructose, and sucrose. In fermentations with glucose hydrogen yields and productivities were similar for both strains. With fructose the hydrogen yield of C. saccharolyticus was reduced which might be related to uptake of glucose and fructose by different types of transport systems. With T. neapolitana the fructose consumption rate and consequently the hydrogen productivity were low. The hydrogen yields of both thermophiles were 2.7-2.8 mol H{sub 2}/mol hexose with 10 g/L sugars from carrot pulp hydrolysate. With 20 g/L sugars the yield of T. neapolitana was 2.4 mol H{sub 2}/mol hexose while the yield of C. saccharolyticus was reduced to 1.3 mol H{sub 2}/mol hexose due to high lactate production in the stationary growth phase. C. saccharolyticus was able to grow on carrot pulp and utilized soluble sugars and, after adaptation, pectin and some (hemi)cellulose. No growth was observed with T. neapolitana when using carrot pulp in agitated fermentations. Enzymatic hydrolysis of the polysaccharide fraction prior to fermentation increased the hydrogen yield with almost 10% to 2.3 g/kg of hydrolyzed carrot pulp. (author)

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. © 2015 The Authors The Plant Journal © 2015 John Wiley & Sons Ltd.

Full Text Available The article presents a sustainability assessment of the beet-to-sugar production system in Sweden from 2003 until 2015. It focuses on the life-cycle phases of beet growing, beet transport and sugar processing. Based on the Swedish sustainable development strategy, eight indicators in environmental and socio-economic domains based significantly on EU price and production quota changes are assessed. The study also appraises the autumn wheat-to-flour production system as an alternative scenario to provide a better understanding of the overall impacts on the region of the effects of the EU price and quota changes. The method used is a system analysis (simulation model developed with the software STELLA 9.1. The study is a part of a broader regional sustainability assessment that focuses on the sugar sector in Sweden. Model results of the combined sugar and flour systems show general declines in agricultural landscape diversity and revenues earned in the region with only slight decreases in the number of full-time jobs in the region. Results also reveal decreases in the amount of nutrient runoff, fossil fuel energy use, greenhouse gas releases and field chemical use, with more substantial decreases in biodiversity via the suspension of organic beet growing in the region.

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.

Improvement of the energy balance and efficiency for reduced input of cropping systems is one of the main goals for the cultivation of energy crops. In this field study, two sugar crops for bioethanol production were cultivated under different soil tillage management (conventional; no tillage) and mineral nitrogen application (0, 75, 150 kg N ha"−"1): sweet sorghum and sugar beet. The energy performance and efficiency along the bioethanol supply chain were analysed and compared. Both of these crops showed good growth adaptation to the different soil and nitrogen management, and thus the energy return, resource and energy efficiencies were significantly improved in the low-input system. Sweet sorghum provided better responses in terms of water and nitrogen use efficiency for biomass accumulation, as well as its energy yield and net gain, compared to sugar beet, whereas sugar beet showed higher energy efficiency than sorghum. According to these data, both of these crops can be cultivated in a Mediterranean environment with low energy input, which guarantees good crop and energy performances for biofuel strategy planning. - Highlights: • Two sugar crops for the bioethanol supply chain were evaluated. • Energy performances and efficiencies were assessed under different energy input. • Sugar yield resulted not compromised by the different crop management. • The energy gain was improved with low energy input at field level. • Sweet sorghum gave the highest energy yield, sugar beet the energy efficiency.

Full Text Available Crop Fe deficiency is a worldwide problem. The aim of this study was to assess the effects of foliar Fe applications in two species grown in different environments: peach (Prunus persica L. Batsch trees grown in the field and sugar beet (Beta vulgaris L. cv. ‘Orbis’ grown in hydroponics. The distal half of Fe-deficient, chlorotic leaves was treated with Fe sulfate by dipping and using a brush in peach trees and sugar beet plants, respectively. The re-greening of the distal (Fe-treated and basal (untreated leaf areas was monitored, and the nutrient and photosynthetic pigment composition of the two areas were also determined. Leaves were also studied using chlorophyll fluorescence imaging, low temperature-scanning electron microscopy microanalysis, scanning transmission ion microscopy-particle induced X-ray emission and Perls Fe staining. The distal, Fe-treated leaf parts of both species showed a significant increase in Fe concentrations (across the whole leaf volume and marked re-greening, with significant increases in the concentrations of all photosynthetic pigments, as well as decreases in de-epoxidation of xanthophyll cycle carotenoids and increases in photochemical efficiency. In the basal, untreated leaf parts, Fe concentrations increased slightly, but little re-greening occurred. No changes in the concentrations of other nutrients were found. Foliar Fe fertilization was effective in re-greening treated leaf areas both in peach trees and sugar beet plants. Results indicate that the effects of foliar Fe-sulfate fertilization in Fe-deficient, chlorotic leaves were minor outside the leaf surface treated, indicating that Fe mobility within the leaf is a major constraint for full fertilizer effectiveness in crops where Fe-deficiency is established and leaf chlorosis occurs.

2012-05-01

The effects of feeding bees artificial sugars and/or proteins on the sugar compositions and (13)C isotopic measurements of royal jellies (RJs) were evaluated. The sugars fed to the bees were two C4 sugars (cane sugar and maize hydrolysate), two C3 sugars (sugar beet, cereal starch hydrolysate), and honey. The proteins fed to them were pollen, soybean, and yeast powder proteins. To evaluate the influence of the sugar and/or protein feeding over time, samples were collected during six consecutive harvests. (13)C isotopic ratio measurements of natural RJs gave values of around -25 ‰, which were also seen for RJs obtained when the bees were fed honey or C3 sugars. However, the RJs obtained when the bees were fed cane sugar or corn hydrolysate (regardless of whether they were also fed proteins) gave values of up to -17 ‰. Sugar content analysis revealed that the composition of maltose, maltotriose, sucrose, and erlose varied significantly over time in accordance with the composition of the syrup fed to the bees. When corn and cereal starch hydrolysates were fed to the bees, the maltose and maltotriose contents of the RJs increased up to 5.0 and 1.3 %, respectively, compared to the levels seen in authentic samples (i.e., samples obtained when the bees were fed natural food: honey and pollen) that were inferior to 0.2% and not detected, respectively. The sucrose and erlose contents of natural RJs were around 0.2 %, whereas those in RJs obtained when the bees were fed cane or beet sugar were as much as 4.0 and 1.3 %, respectively. The combination of sugar analysis and (13)C isotopic ratio measurements represents a very efficient analytical methodology for detecting (from early harvests onward) the use of C4 and C3 artificial sugars in the production of RJ.

The analysis of major and minor monosaccharides, aliphatic carboxylic acids and furfurals has been optimised. An important drawback of the spent liquors generated after sulphite pulping is their acidic nature, high viscosity and adhesive properties that interfere in the column lifetime. This work recommends both a CHO-782Pb column for the sugar analysis and an SH-1011 resin-based cross-linked gel column to separate low-molecular-weight chain acids, alcohols and furfurals. Such columns resulted in a good separation with long lifetime, wide pH operating range and low fouling issues.

A flocculent killer yeast, strain H-1 selected for ethanol fermentation of beet molasses, has a tendency to lose its viability in distillery waste water (DWW) of beet molasses mash after ethanol fermentation. Through acclimations of strain H-1 in DWW, strain W-9, resistant to DWW, was isolated. Strain M-9, resistant to 2-deoxyglucose was further isolated through acclimations of strain W-9 in medium containing 150 ppm 2-deoxyglucose. A fermentaion test of beet molasses indicated that the ethanol productivity and suger consumption were improved by strain M-9 compared with the parental strain H-1 and strain W-9. The concentration of ethanol produced by strain M-9 was 107.2 g/1, and concentration of residual sugars, which were mainly composed of sucrose and fructose, were lower than those produced by the parental strain H-9 and strain W-9 at the end of fermentation of beet molasses. 6 refs., 2 figs., 2 tabs.

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)

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

International Nuclear Information System (INIS)

Mikami, Tetsuo; Kinoshita, Toshiro; Takahashi, Man-emon

1976-01-01

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 M 4 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.)

This work investigated the feasibility of recovering and concentrating sugars and acetic acid (HAc) from prehydrolysis liquor (PHL) of the kraft-based dissolving pulp process prior to fermentation of hemicellulosic sugars, by the combination of activated carbon adsorption, nanofiltration (NF) and reverse osmosis (RO) processes. To reduce the fouling PHL was subjected to adsorption on activated carbon, then the treated PHL (TPHL) passed through a nanofiltration (NF DK) membrane to retain the sugars, and the permeate of acetic acid rich solution was passed through a reverse osmosis membrane (RO SG). It was found that for NF process sugars were concentrated from 48 to 227g/L at a volume reduction factor (VRF) of 5 while 80 to 90% of acetic acid was permeated. For the reverse osmosis process, 68% of acetic acid retention was achieved at pH 4.3 and 500 psi pressure and the HAc concentration increased from 10 to 50g/L. Crown Copyright © 2013.

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.

The present study investigated the application of near infrared spectroscopy as a green, quick, and efficient alternative to analytical methods currently used to evaluate the quality (moisture, total sugars, acidity, soluble solids, pH and ascorbic acid) of frozen guava and passion fruit pulps. Fifty samples were analyzed by near infrared spectroscopy (NIR) and reference methods. Partial least square regression (PLSR) was used to develop calibration models to relate the NIR spectra and the reference values. Reference methods indicated adulteration by water addition in 58% of guava pulp samples and 44% of yellow passion fruit pulp samples. The PLS models produced lower values of root mean squares error of calibration (RMSEC), root mean squares error of prediction (RMSEP), and coefficient of determination above 0.7. Moisture and total sugars presented the best calibration models (RMSEP of 0.240 and 0.269, respectively, for guava pulp; RMSEP of 0.401 and 0.413, respectively, for passion fruit pulp) which enables the application of these models to determine adulteration in guava and yellow passion fruit pulp by water or sugar addition. The models constructed for calibration of quality parameters of frozen fruit pulps in this study indicate that NIR spectroscopy coupled with the multivariate calibration technique could be applied to determine the quality of guava and yellow passion fruit pulp.

fungal species were screened for their ability to produce pectinases on sugar-beet pulp medium. The highest producer strain was identified as Penicillium citrinum. The optimum conditions for polygalacturonases production were achieved by growing the fungus on sugar beet pulp mineral salts medium and incubation for 7 days at 250 degree C, ph 5.5 and 0.04 g N/g dry SBP by using the conventional method and 1.2 % of nitrogen source by using the factorial design method and surfactant of 0.1% Tween 40. The use of gamma irradiation at a dose of 0.7% kGy yields the highest increase of production of PGase. Polygalacturonases were precipitated from culture supernatant using ammonium sulphate then purified by gel filtration chromatography on sephadex G-100. The optimum ph and temperature of the enzyme activity production were found to be 6.0 and 40°C respectively. The enzyme was found to be stable at ph rang 4 – 8 and showed high stability at temperature rang 20°C -60°C. Mg +2 and Zn +2 stimulated PGase activity.

Full Text Available The influence of benzoic acid and formic acid (positive control of ensilaged maize and pressed sugar beet pulp on quality fermentation processes was studied in a laboratory experiment. The effect of additive on the quality of fermentation process during maize ensiling was studied in a first model experiment. Preservatives such as formic acid and benzoic acid were added to ensiled maize at the concentration of 1L/t and 1 kg/t, respectively. When benzoic acid was used as a preservative, the pH and the N-NH3/ N total ratio decreased statistically (PSugar beet pulp silages with benzoic acid or formic acid after 32 days of storage had a better sensuous evaluation than the control silage. The most intensive decrease of pH value was observed after formic acid addition as compared with control silage. The statistically significantly (P<0.05 highest lactic acid content (49.64 ± 0.28 as well as the highest ratio of LA/VFA were found in the sugar beet pulp silage with benzoic acid. Lactic acid constituted the highest percentage (P<0.05 of all fermentation acids in the silage with benzoic acid additive (65.12 ± 0.80. Undesirable butyric acid (BA was not found in any variant of silages.

The combined action of endo-polygalacturonase (endo-PGII), pectin lyase (PL), pectin methyl esterase (fungal PME) and RG-I degrading enzymes enabled the extended degradation of methylesterified and acetylated sugar beet pectins (SBPs). The released oligomers were separated, identified and quantified using hydrophilic interaction liquid chromatography (HILIC) with online electrospray ionization ion trap mass spectrometry (ESI-IT-MS(n)) and evaporative light scattering detection (ELSD). By MS(n), the structures of galacturonic acid (GalA) oligomers having an acetyl group in the O-2 and/or O-3 positions eluting from the HILIC column were elucidated. The presence of methylesterified and/or acetylated galacturonic acid units within an oligomer reduced the interaction with the HILIC column significantly compared to the unsubstituted GalA oligomers. The HILIC column enables a good separation of most oligomers present in the digest. The use of ELSD to quantify oligogalacturonides was validated using pure GalA standards and the signal was found to be independent of the chemical structure of the oligomer being detected. The combination of chromatographic and enzymatic strategies enables to distinguish SBPs having different methylesters and acetyl group distribution. Copyright © 2012 Elsevier Ltd.

The influence of the feeding ratio of a non-forage fiber source and hay on ruminal mat characteristics and chewing activity was evaluated in dairy dry cows. Cows were fed four different diets: the ratios of alfalfa hay (AH) to beet pulp (BP) were 8:2 (dry matter basis, A8B2) and 2:8 (A2B8), and those of grass hay (GH) to BP were 8:2 (G8B2) and 2:8 (G2B8). Total eating time was decreased with increasing BP content (P rumination time for AH was shorter than that for GH (P content (P ruminal mat was detected by using a penetration resistance test of the rumen digesta. Penetration resistance value (PRV) of ruminal mat was highest with the G8B2 diet and PRV decreased with increasing BP content (P ruminal mat was greater for increasing BP content (P ruminal mat PRV on total rumination time resulted in a high positive correlation (r = 0.744; P ruminal mat stimulated rumination activity and a ruminal mat could be formed, although it was soft even when cows were offered a large quantity of BP.

The accelerated use of iron oxide nanoparticles (IONPs) and multi-wall carbon nanotubes (MWCNTs) in the consumer and industrial sectors has triggered the need to understand their potential environmental impact. The response of anaerobic granular sludge (AGS) to IONPs and MWCNTs during the anaerobic digestion of beet sugar industrial wastewater (BSIW) was investigated in this study. The IONPs increased the biogas and subsequent CH 4 production rates in comparison with MWCNTs and the control samples. This might be due to the utilization of IONPs and MWCNTs as conduits for electron transfer toward methanogens. The MWCNTs majorly enriched the bacterial growth, while IONP enrichment mostly benefitted the archaea population. Furthermore, scanning electron microscopy and confocal laser scanning microscopy revealed that AGS produced extracellular polymeric substances, which interacted with the IONPs and MWCNTs. This provided cell protection and prevented the nanoparticles from piercing through the membranes and thus cytotoxicity. The results provide useful information and insights on the adjustment of anaerobic microorganisms to the natural complex environment based on nanoparticles infiltration.

Terboven, Christiane; Ramm, Patrice; Herrmann, Christiane

2017-10-01

A newly developed fixed bed disc reactor (FBDR) which combines biofilm formation on biofilm carriers and reactor agitation in one single system was assessed for its applicability to demand-driven biogas production by variable feeding of sugar beet silage. Five different feeding patterns were studied at an organic loading of 4g VS L -1 d -1 under mesophilic and thermophilic conditions. High methane yields of 449-462L N kg VS were reached. Feeding variable punctual loadings caused immediate response with 1.2- to 3.5-fold increase in biogas production rates within 15min. Although variable feeding did not induce process instability, a temporary decrease in pH-value and methane concentration below 40% occurred. Thermophilic temperature was advantageous as it resulted in a more rapid, higher methane production and less pronounced decrease in methane content after feeding. The FBDR was demonstrated to be well-suited for flexible biogas production, but further research and comparison with traditional reactor systems are required. Copyright © 2017 Elsevier Ltd.

Hanna S. Hörhammer

2012-06-01

Full Text Available This study deals with a biorefinery concept based on larch wood. Wood chips of Siberian larch (Larix sibirica Lebed. were treated with water before pulping at the optimal pre-extraction (PE condition of 150 °C and 90 minutes. Through PE, about 12.4% of the wood mass is dissolved, mainly from the arabinogalactan hemicellulose component. Fermentation of the hemicellulose-rich larch extract with Bacillus coagulans resulted in consumption of all C6 and C5 sugars and produced lactic acid in high yield. PE before pulping resulted in lower (4 to 5% pulp yield than for control kraft pulps. However, the pulp yield loss may be reduced by addition of polysulfide (PS and anthraquinone (AQ. The present study focuses on the effect of the degree of washing of the extracted chips and that of the PS charge in PSAQ pulping on the final properties of the pulp. Three different levels of washing and three different PS charges were tested. The characteristics of the extract, wash water, pulp, and black liquor samples were determined. The amount of sugars in the combined stream of collected extract and wash water obtained by mild washing was 10.2% on o.d. wood.

Full Text Available The study aimed to develop two formulations (F1 and F2 of probiotic mango smoothie with fermented milk, and to evaluate the microbiological viability and physicochemical (pH, acidity and desorption characteristics under refrigerated storage. The formulation F1 was prepared with addition of 30% of mango pulp and 10% of sugar, and in F2 was added 40% of pulp and 8% of sugar. The hygienic sanitary quality was satisfactory, and the samples were safe for consumption. The samples did not differ in pH, titratable acidity, syneresis and viability of the microorganisms along the refrigerated storage, therefore, the sugar and pulp levels did not significantly influence the formulations. Probiotic levels remained within the dose considered therapeutic. Therefore, these beverages F1 and F2 may be considered appropriate vehicles for incorporation of probiotics and a new functional product may be made available to the market.

Hou, Jun-Jie; Guo, Jian; Wang, Jin-Mei; Yang, Xiao-Quan

2016-10-01

In this study, soy protein isolate/sugar beet pectin (SPI/SBP) emulsion gels were prepared through an enzymatic gelation process. The effects of emulsifier (SBP, SPI or SPI/SBP complex) and emulsification process on the microstructure, texture, breakdown properties and aroma release behavior of resulting emulsion gels were investigated. Oil emulsification by SBP/SPI complex resulted in a higher amount of emulsifier absorbing on the oil-water interface than by SBP and SPI alone, indicating that a more compact interfacial network was formed. Flocculation of oil droplets was observed and corresponding emulsion gels exhibited lower fracture force and strain when the oil was emulsified by SPI and SBP/SPI complex. Moreover, emulsion gels with small droplets produced a greater quantity of small fragments after mastication. However, microstructure did not have a significant effect on breakdown properties of emulsion gels. Headspace gas chromatography analysis showed that the release rate of ethyl butyrate before and after mastication was significantly lower in emulsion gel with more compact network, but the release of aroma compounds with higher hydrophobicity did not show a significant influence of the microstructure and texture of emulsion gel. This finding provides a useful application for designing semi-solid foods with desirable flavor perception. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Drought Impact Is Alleviated in Sugar Beets (Beta vulgaris L.) by Foliar Application of Fullerenol Nanoparticles.

Over the past few years, significant efforts have been made to decrease the effects of drought stress on plant productivity and quality. We propose that fullerenol nanoparticles (FNPs, molecular formula C60(OH)24) may help alleviate drought stress by serving as an additional intercellular water supply. Specifically, FNPs are able to penetrate plant leaf and root tissues, where they bind water in various cell compartments. This hydroscopic activity suggests that FNPs could be beneficial in plants. The aim of the present study was to analyse the influence of FNPs on sugar beet plants exposed to drought stress. Our results indicate that intracellular water metabolism can be modified by foliar application of FNPs in drought exposed plants. Drought stress induced a significant increase in the compatible osmolyte proline in both the leaves and roots of control plants, but not in FNP treated plants. These results indicate that FNPs could act as intracellular binders of water, creating an additional water reserve, and enabling adaptation to drought stress. Moreover, analysis of plant antioxidant enzyme activities (CAT, APx and GPx), MDA and GSH content indicate that fullerenol foliar application could have some beneficial effect on alleviating oxidative effects of drought stress, depending on the concentration of nanoparticles applied. Although further studies are necessary to elucidate the biochemical impact of FNPs on plants; the present results could directly impact agricultural practice, where available water supplies are often a limiting factor in plant bioproductivity.

Characteristics of fermentation of refined cane sugar syrup for alcohol

Energy Technology Data Exchange (ETDEWEB)

Raev, Z A; Bazilevich, K K

1956-01-01

Technological properties of cane sugar syrup, obtained on refining of raw cane sugar, were investigated. Its poor fermentation is caused by the lack of nitrous substances (1/10 as much as in sugar beet) necessary for the nutrition of yeast. It is necessary to introduce into the mixture of yeast and must 0.8% (NH/sub 4/)/sub 2/SO/sub 4/ based on weight of syrup (at a permanent aeration the assimilability of N from (NH/sub 4/)/sub 2/SO/sub 4/ by the yeast will be higher and the dosage has to be increased), 1% of superphosphate or 0.12% of a 70% phosphoric acid solution, and 0.5% of a yeast autolyst. For the fermentation of cane sugar syrup the mixture of yeast and must has to be prepared with a concentration of 10 to 11/sup 0/ by the saccharometer scale, but the average initial concentration of the fermentive must has to be 17 to 18/sup 0/ with the intention to keep the alcohol content of the ripe must at 8.7 to 8.8% by volume. Considering the low buffer ability of the syrup from cane sugar, the acidity of the must, mixed with yeast, has to be kept less than or equal to 0.4 to 0.5/sup 0/, the pH at 4.6 to 4.8; on a higher acidity the pH drops to a value which inhibits the fission of the yeast cells. On a joint fermentation of syrup from sugar cane and sugar beets 1% of superphosphate in the form of an aqueous extract and an autolyst of yeast in an amount of 0.5% of the weight of syrup was introduced into the must; the yield of alcohol from cane sugar syrup increased compared with the yield on separate processing.

Sustainability Issues and Opportunities in the Sugar and Sugar-Bioproduct Industries

Gillian Eggleston

2015-09-01

Full Text Available Like many other industries, the sugar and sugar-bioproduct industries are facing important sustainability issues and opportunities. The relatively low and fluctuating profit for sugar, surpluses of sugar, world-wide trend to produce alternative, renewable bio-based fuels and chemicals to those derived from petroleum and reduce greenhouse gases, water- and energy-intensive factories and refineries, and increased consumer demands for sustainably manufactured products are putting pressure on the industries to diversify for sustainability. Sugar crops, including sugar and energy cane (Saccharum officinarum, sugar and energy beets (Beta vulgaris, and sweet sorghum (Sorghum bicolor L. Moench, are excellent, renewable biomass feedstocks because of their availability, their being amongst the plants that give the highest yields of carbohydrates per hectare, and high sugar contents. While much research has been focused on conversion technologies for advanced biofuels and bioproducts, attention is now focused on developing sustainable supply chains of sugar feedstocks for the new, flexible biorefineries, with customers wanting maximum feedstock reliability and quality, while minimizing cost. All biomass from sugar crops are potential feedstocks. The cogeneration of bioelectricity from bagasse and leaf residues is being increasingly manufactured in more countries and, due to the high carbon content of bagasse and leaves, can also be converted into value-added products such as biochar. Sugar crops are superior feedstocks for the production of platform chemicals for the manufacture of a range of end-products, e.g., bioplastics, chemicals, and biomaterials. In several countries and regions, green sustainability criteria are now in place and have to be met to count against national biofuel targets. Processes to convert high-fiber sugar crop biomass into biofuel have been developed but there has only been limited commercialization at the large-scale.

Full Text Available Objective Two ex vivo experiments were conducted to verify the effect of barley grain (Nusrat cultivar treated with alkaline compounds (AC including alum, ammonium, and sodium hydroxide or cation-exchanged organic extracts (OE prepared from alfalfa hay, sugar beet pulp and Ulva Fasciata, on extent and digestion of starch. Methods In the first study, the in vitro first order disappearance kinetic parameters of dry matter (DM, crude protein (CP and starch were estimated using a non-linear model (D(t = D(i · e(−kd · time + I, where: D(t = potentially digestible residues at any time, D(i = potentially digestible fraction at any time, kd = fractional rate constant of digestion (/h, I = indigestible fraction at any time. In the second experiment, the ruminal and post-ruminal disappearance of DM, CP, and starch were determined using in situ mobile nylon bag. Results Barley grains treated with alum and alfalfa extract had a higher constant rate of starch digestion (0.11 and 0.09/h than others. Barley grain treated with OE had a higher constant rate of CP digestion and that of treated with AC had a higher constant rate of starch digestion (0.08 and 0.11/h compared with those of the other treatments. The indigestible fraction of starch treated with alum and sugar beet pulp extract was higher than that of the control group (0.24 and 0.25 vs 0.21. Barley grain treated with AC and OE had significant CP disappearance in the rumen, post-rumen and total tract, and also starch disappearance for post-rumen and total tract compared with the untreated (p<0.001. Conclusion This study demonstrated that AC and OE might have positive effects on the starch degradation of the barley grain. In addition, treating barley grain with alum and sugar beet pulp extract could change the site and extend digestion of protein and starch.

Effect of different concentration of sucrose and potassium metabisulphite on the apricot pulp was studied fortnightly for 90 days through physicochemical and microbial analysis. No significant change in total soluble solids (TSS) of apricot pulp was observed during the storage. Acidity and non-reducing sugar significantly (p<0.05) decreased, while pH and reducing sugars significantly (p<0.05) increased during the storage. Samples with added 20% sucrose and 0.2% potassium metabisulphite, packed in plastic and glass containers, had negligible microbial population maintained maximum nutrients and the best sensory characteristics during the storage. Storage duration and treatments had significant (p<0.05) effect on pH, acidity, non reducing sugars and total fungal count, while on TSS (total soluble solids) and reducing sugar, the effect of treatments was nonsignificant (p<0.05).

De Leon, R.; Calzada, F.; Herrera, R.; Rolz, C.

1980-01-01

Coffee pulp or skin represents about 40% of the weight of the fresh coffee fruit. It is currently a waste and its improper handling creates serious pollution problems for coffee producing countries. Mechanical pressing of the pulp will produce two fractions: coffee pulp juice (CPJ) and pressed pulp. Aspergillus oryzae, Trichoderma harzianum, Penicillium crustosum and Gliocladium deliquescens grew well in supplemented CPJ. At shake flask level the optimum initial C/N ratio was found to be in the range of 8 to 14. At this scale, biomass values of up to 50 g/l were obtained in 24 hours. Biomass production and total sugar consumption were not significantly different to all fungal species tested at the bench-scale level, even when the initial C/N ratio was varied. Best nitrogen consumption values were obtained when the initial C/N ratio was 12. Maximum specific growth rates occurred between 4-12 hours for all fungal species tested. (Refs. 8).

Increase of alcohol yield per ton of pulp

Energy Technology Data Exchange (ETDEWEB)

Sokolov, B N

1957-01-01

Digestion processes of cellulose were studied under production conditions. When the digestion was carried out with acid having 5.2% total SO/sub 2/ and 0.92% CaO, the concentration of total sugars in the spent liquor was 1.8 to 2.5%. When the acidity was reduced to 4.8% total SO/sub 2/ and 0.82% CaO, all other conditions being the same, the sugar concentration in the spent liquor increased to 3.0 to 3.7%. The importance of the acid strength and CaO content of the cooking liquor was further demonstrated at the end of 1955. At that time the total SO/sub 2/ in the acid rose to 8% while the amount of CaO remained practically the same-0.85 to 0.90%. These conditions permitted an increase in the amount of ships by 25 to 30%, which further changed the ratio CaO: wood and created conditions favorable for an improved yield of sugar. The increase in the activity of the acid was reflected favorably in the degree of hydrolysis of the hemicelluloses and in the degree to which the oligosaccharides or polysaccharides were hydrolyzed to simple sugars. At that time the yield of alcohol reached 53 1/ton of unbleached pulp. The process was further improved in 1956 by the use of successive washings; at the end of the digestion period the concentrated spent liquor was piped to the alcohol unit. The yield of alcohol reached 59.4 1/ton of pulp. Sugar recovery from the tank was 92.5% of that theoretically possible. Further improvements resulted by saturating the wood chips with acid under variable pressures. As a result, the base of the cooking acid was reduced to 0.7 to 0.72% and, at the end of the process the liquor contained 0.03 to 0.06% CaO instead of 0.2 to 0.18%. The alcohol yield/ton of pulp then rose to 66.8 l.

Full Text Available An extensive survey was conducted during the summer and autumn of 2004 in sugar beet fields in the area of Larissa, Thessaly region, with plants showing symptoms of root rot diseases. The aim of the monitoring was to identify the causal agents of root rot diseases. In total, 76 sugar beet fields were surveyed and 5-10 diseased roots were examined from each field. Isolations, carried out on PDA, showed that two main fungal pathogens causing root rot were Rhizoctonia solani and Phytophthora cryptogea. The former was isolated in 46% of the fields and the latter in 38% of the fields. In addition, Rhizopus stolonifer, Fusarium spp., Scerotium rolfsii and Rhizoctonia violacea were isolated in 14%, 7%, 4% and 1% of the fields respectively. In most of the surveyed fields only one pathogen species was isolated and only in a few of them more than one fungal species was identified.

The numerical solution of Fick's' law for unsteady-state mass transfer in a perfect cube configuration was used to calculate the effective diffusivities of water, sucrose and minerals (Na, K, Ca and Mg. Zugarramurdi and Lupin's model was used to predict the equilibrium condition, which was shown to be appropriate for water loss and solute uptake during osmotic treatment. Effective diffusivity of water was found to be in the range of 6.95×10-10 - 8.03×10-10 m2s-1, the sucrose effective diffusivity was between 6.39×10-10 and 8.25×10-10 m2s-1, while diffusivities for minerals were in the range 6.34×10-10 - 8.82×10-10 m2s-1, for Na, 6.27×10-10 - 7.43×10-10 m2s-1, for K, 6.44×10-10 - 8.94×10-10 m2s-1, for Ca and 3.47×10-10 - 5.66×10-10 m2s-1, for Mg.

The effects of 5-(N-methyl-N-isobutyl)-amiloride (MIA), an amiloride analog, was tested on the Na(+)/H(+) antiport activity of intact vacuoles and tonoplast vesicles isolated from sugar beet (Beta vulgaris L.) cell suspension cultures. MIA inhibited Na(+)/H(+) exchange in a competitive manner with a K(i) of 2.5 and 5.9 micromolar for DeltapH-dependent (22)Na(+) influx in tonoplast vesicles and Na(+)-dependent H(+) efflux in intact vacuoles, respectively. Scatchard analysis of the binding of [(3)H]MIA to tonoplast membranes revealed a high affinity binding component with a K(d) of 1.3 micromolar. The close relationship between the dissociation constant value obtained and the constants of inhibition for MIA obtained by fluorescence quenching and isotope exchange suggests that the high affinity component represents a class of sites associated with the tonoplast Na(+)/H(+) antiport. Photolabeling of the tonoplast with [(3)H]MIA revealed two sets of polypeptides with a different affinity to amiloride and its analog.

Transcriptome Analysis of Beta macrocarpa and Identification of Differentially Expressed Transcripts in Response to Beet Necrotic Yellow Vein Virus Infection.

Directory of Open Access Journals (Sweden)

Full Text Available Rhizomania is one of the most devastating diseases of sugar beet. It is caused by Beet necrotic yellow vein virus (BNYVV transmitted by the obligate root-infecting parasite Polymyxa betae. Beta macrocarpa, a wild beet species widely used as a systemic host in the laboratory, can be rub-inoculated with BNYVV to avoid variation associated with the presence of the vector P. betae. To better understand disease and resistance between beets and BNYVV, we characterized the transcriptome of B. macrocarpa and analyzed global gene expression of B. macrocarpa in response to BNYVV infection using the Illumina sequencing platform.The overall de novo assembly of cDNA sequence data generated 75,917 unigenes, with an average length of 1054 bp. Based on a BLASTX search (E-value ≤ 10-5 against the non-redundant (NR, NCBI protein, Swiss-Prot, the Gene Ontology (GO, Clusters of Orthologous Groups of proteins (COG and Kyoto Encyclopedia of Genes and Genomes (KEGG databases, there were 39,372 unigenes annotated. In addition, 4,834 simple sequence repeats (SSRs were also predicted, which could serve as a foundation for various applications in beet breeding. Furthermore, comparative analysis of the two transcriptomes revealed that 261 genes were differentially expressed in infected compared to control plants, including 128 up- and 133 down-regulated genes. GO analysis showed that the changes in the differently expressed genes were mainly enrichment in response to biotic stimulus and primary metabolic process.Our results not only provide a rich genomic resource for beets, but also benefit research into the molecular mechanisms of beet- BNYV Vinteraction.

The effects of 5-(N-methyl-N-isobutyl)-amiloride (MIA), an amiloride analog, was tested on the Na + /H + antiport activity of intact vacuoles and tonoplast vesicles isolated from sugar beet (Beta vulgaris L.) cell suspension cultures. MIA inhibited Na + /H + exchange in a competitive manner with a K i of 2.5 and 5.9 micromolar for ΔpH-dependent 22 Na + influx in tonoplast vesicles and Na + -dependent H + efflux in intact vacuoles, respectively. Scatchard analysis of the binding of [ 3 H]MIA to tonoplast membranes revealed a high affinity binding component with a K d of 1.3 micromolar. The close relationship between the dissociation constant value obtained and the constants of inhibition for MIA obtained by fluorescence quenching and isotope exchange suggests that the high affinity component represents a class of sites associated with the tonoplast Na + /H + antiport. Photolabeling of the tonoplast with [ 3 H]MIA revealed two sets of polypeptides with a different affinity to amiloride and its analog

Full Text Available Sugar yield, an important indicator, is resulting from interaction of two components: the yield and sugar content, both they are controlled by polygenes, and influenced significantly by environment. A.V. Kilchevskyi and L.V. Hotyliova pointed to the fact that in breeding, contrary to evolution, stabilizing forms are dominated by driving ones, which determine the growth response to regulated factors and decreased resistance to non-regulated environmental factors [1]. A relevant breeding trend is to create the genotypes adequate with certain technologies, so to say «low input variety high input variety» i.e. varieties with low and high energy contribution to technology. From this perspective, selection of stable in their manifestation lines against the analyzing backgrounds has become an important element of the breeding process [2]. Home scientists, such as A.L. Mazmulov and M.S. Hrytsyk have contributed greatly to the development and application of the agro-backgrounds [3, 4].

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

Full Text Available As the fossil energy decrease such as petroleum and natural gas, that are encourages a lot of research to develop new sources of energy from renewable raw materials. One of the source is through reducing sugar (glucose and xylose obtained from coffee pulp waste; this is due to abundant production of coffee pulp every year reaching 743 kg/ha. In addition, this waste has not been used optimally and the cellulose and hemicellulose content of the coffee is high. The purpose of this study is to get the optimal operating condition for reducing sugar production from coffee pulp waste. The method used for optimization is Response Surface Methodology with Central Composite Design. The optimum operation condition obtained was pH 4.63 at 34ºC for 16.29 hours of hydrolysis. As a result, the predicted yield gained was 0.147 grams of reducing sugars / gram of cellulose+hemicellulose. The result indicates the gained yield was 0.137 grams of reducing sugars / gram of cellulose+hemicellulose.

One of potential non wood bioresources utilized in industrial application is bamboos. Bamboos are include in graminae family which have high biomass productivity, easy and rapid production, wide avability and high holocellulose content. Indonesia has a huge potential of bamboos, more than 162 bamboo species are found however only some of them are planted that have a high economic value. Bamboos have some advantages such as can be harvested at 3 years, straight culm, high strength, easy to be processed, and relatively cheap. Research Center for Biomaterials has developed utilization of bamboo culm for ply bamboo product as alternative of plywood since 1995, using gombong bamboo, tali bamboo, sembilang bamboo, andong bamboo with PF resin as adhesive. Other biocomposite products from bamboos include particle board, cement board and polymer-bamboo fiber composites. In term of processing technique and final product quality, bamboo composites from ply bamboo are the most prospectable material to be utilized in industrial application. Yellow bamboo and betung bamboo have also been developed as pulp and paper. Biopulping using soda and kraft pulping after biological pretreatment using white rot fungi to remove lignin was used as pulping method in this conversion. Biokraft pulping with Trametes versicolor for 45 days with inoculum loading of 10% resulted better pulp quality compared to the other fungi. Betung bamboo had good morphological characteristics and chemical component content to be converted into bioenergy such as bioethanol. Several pretreatment methods have been developed in order to result high sugar yield. Microwave assisted acid hydrolysis was preferedin producing higher yield from the pretreated bamboo compared to enzymatic hydrolysis. By using this method, the bamboo pretreated by biological-microwave pretreatment results higher improvement to increase sugar yield.

Formowanie powierzchni asymilacyjnej i biomasy przez rośliny buraków cukrowych [Formation of the assimilation area and biomass by sugar beet plants

Full Text Available Measurements were carried out of the assimilation area, NAR value, the crop growth rate (C and of the yield of roots and leaves of sugar beet plants in a production field during two successive vegetation years. An interdependence was found between the formation of the assimilation area in the canopy and the final yield of biomass. The assimilation area depended mainly on the date of sowing. In 1975, the sowing was earlier by 15 days, amid this resulted in a much more favourable LAI and in a higher yield of biomass. During both vegetation years, a violent decrease of the crop growth rate was observed at the end of August and at the beginning of September. This may be due to an unfavourable change in the ratio of the area of younger, photosynthetically active leaves to older, less active leaves and also to the increased participation of the loss of the assimilates resulting from stronger respiration of the fast growing roots while the photosynthesis of the whole plants decreases.

Co-production of fermentable sugars and nanofibrillated cellulose from cassava pulp was achieved by the combination of thermophilic enzymes (endoglucanase, β-glucosidase, and α-amylase) and a new atomization system (Star Burst System; SBS), which employs opposing water jets. The SBS represents a key technology for providing cellulose nanofibers and improving the enzymatic saccharification of cassava pulp. Depending on the enzymes used, the production of glucose from cassava pulp treated with the SBS was 1.2- to 2.5-fold higher than that from pulp not treated with the SBS. Nanofibrillated cellulose with the gel-like property in suspension was produced (yield was over 90%) by α-amylase treatment, which completely released trapped starch granules from the fibrous cell wall structure of cassava pulp pretreated with the SBS. The SBS provides an environmentally low-impact pretreatment system for processing biomass material into value-added products. Copyright © 2012 Elsevier Ltd. All rights reserved.

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
