    Full Text Available The influence of oxygen supply rate on the growth and the production of both ethanol and acetaldehyde by the aerotolerant fermentative bacterium Z. mobilis is discussed in this work. The results showed similar values of cell mass yield (0.043 g/g for the five different levels of initial volumetric oxygen transfer coefficient (K La studied. The maximum specific growth rate (µx,m. under anaerobic conditions was higher than those found in aerated runs. Anaerobic cultivation resulted in the best ethanol yield (0.38 g/g. For initial K La values of 62, 94, and 118 h-1, ethanol yields were 0.10, 0.12, and 0.09 g/g, respectively, whereas for K La of 30 h-1, an intermediate value (0.24 g/g was achieved. Under anaerobiosis, no acetaldehyde was produced. With initial K La values of 62, 94, and 118 h-1, acetaldehyde yields were similar (0.12 to 0.17 g/g, and for K La of 30 h-1 only 0.07 gram of acetaldehyde was formed per gram of glucose. Although increasing values for the maximal specific acetaldehyde formation rate were calculated as K La was increased, our results showed that the presence of an excess of dissolved oxygen throughout fermentation is enough to provide appropriate conditions for the production of acetaldehyde by Z. mobilis.

    Detailed time-and-space-averaged structure of MgSO4 in the concentrated aqueous solutions was investigated via X-ray diffraction with an X'pert Pro θ-θ diffractometer at 298 K, yielding structural function and radial distribution function(RDF). The developed KURVLR program was employed for the theoretical investigation in consideration of the ionic hydration and ion association. Multi-peaks Gaussian fitting method was applied to deconvolving the overlapping bands of Differential radial distribution function(DRDF). The calculation of the geometric model shows that octahedrally six-coordinated Mg(H2O)62+, with an Mg2+…Ow bond length of 0.201 nm dominates in the solutions. There exists contact ion-pair(CIP) in the more concentrated solution(1:18, H2O/salt molar ratio) with a coordination number of 0.8 and a characteristic Mg…S distance of 0.340 nm. The result indicates the hydrated SO42ion happens in the solution. The S…Ow bond distance was determined to be 0.382 nm with a coordination number of 13. The fraction of CIP increases significantly with the increasing concentration. The symmetry of the hydration structure of sulfate ion is lowered by forming complex with magnesium ion.

    Full Text Available A damaging earthquake of Mw 7.7, which struck the Bhuj region of India on January 26, 2001, was followed by a large number of aftershocks. The aftershock data available at Gauribidanur Seismic Array Station (GBA, India, till 869 h following the main shock were compiled. The plot of the aftershocks rate with time was found to be oscillatory decay. There was a sharp decrease of the aftershocks rate in the initial 144 h from the main shock and this paper presents the analysis of the temporal characteristics of aftershock activity during this period. Astatistical best fit for the rate of aftershocks is performed using the generalised Omori?s law and the exponential decay law. The statistical errors for the exponential fit are found to be lower than that of the generalised Omori's fit. The superimposed oscillations present in the aftershock activity are extracted by differencing the observed aftershock activity from the statistical fits. The frequencies of these oscillations are found to be 0.062 h?1, 0.078 h-1, 0.102 h-1, 0.118 h-1, 0.141 h-1, 0.164 h-1, 0.233 h-1 and 0.476 h-1. Some of the plausible causes for this kind of oscillations present in the aftershock activity are also discussed in this paper.

    Influenza virus neuraminidase (NA) plays a crucial role in facilitating the spread of newly synthesized virus in the host and is an important target for controlling disease progression. The NA crystal structure from the 1918 'Spanish flu' (A/Brevig Mission/1/18 H1N1) and that of its complex with zanamivir (Relenza) at 1.65-{angstrom} and 1.45-{angstrom} resolutions, respectively, corroborated the successful expression of correctly folded NA tetramers in a baculovirus expression system. An additional cavity adjacent to the substrate-binding site is observed in N1, compared to N2 and N9 NAs, including H5N1. This cavity arises from an open conformation of the 150 loop (Gly147 to Asp151) and appears to be conserved among group 1 NAs (N1, N4, N5, and N8). It closes upon zanamivir binding. Three calcium sites were identified, including a novel site that may be conserved in N1 and N4. Thus, these high-resolution structures, combined with our recombinant expression system, provide new opportunities to augment the limited arsenal of therapeutics against influenza.

    Although the sunlight-mediated inactivation of viruses has been recognized as an important process that controls surface water quality, the mechanisms of virus inactivation by sunlight are not yet clearly understood. We investigated the synergistic role of temperature and Suwannee River natural organic matter (SRNOM), an exogenous sensitizer, for sunlight-mediated inactivation of porcine rotavirus and MS2 bacteriophage. Upon irradiation by a full spectrum of simulated sunlight in the absence of SRNOM and in the temperature range of 14-42 °C, high inactivation rate constants, kobs, of MS2 (k obs ≤ 3.8 h-1 or 1-log10 over 0.6 h) and rotavirus (kobs ≤ 11.8 h-1 or ∼1-log10 over 0.2 h) were measured. A weak temperature (14-42 °C) dependence of kobs values was observed for both viruses irradiated by the full sunlight spectrum. Under the same irradiation condition, the presence of SRNOM reduced the inactivation of both viruses due to attenuation of lower wavelengths of the simulated sunlight. For rotavirus and MS2 solutions irradiated by only UVA and visible light in the absence of SRNOM, inactivation kinetics were slow (kobs < 0.3 h-1 or <1-log10 unit reduction over 7 h) and temperature-independent for the range considered. Conversely, under UVA and visible light irradiation and in the presence of SRNOM, temperature-dependent inactivation of MS2 was observed. For rotavirus, the SRNOM-mediated exogenous inactivation was only important at temperatures >33 °C, with low rotavirus kobs values (kobs ≈ 0.2 h-1; 1-log10 unit reduction over 12 h) for the temperature range of 14-33 °C. These kobs values increased to 0.5 h-1 at 43 °C and 1.5 h-1 (1-log10 reduction over 1.6 h) at 50 °C. While SRNOM-mediated exogenous inactivation of MS2 was triggered by singlet oxygen, the presence of hydrogen peroxide was important for rotavirus inactivation in the 40-50 °C range. © 2011 American Chemical Society.
