Efficient cofermentation of D-glucose, D-xylose, and L-arabinose, three major sugars present in lignocellulose, is a fundamental requirement for cost-effective utilization of lignocellulosic biomass. The Gram-positive anaerobic bacterium Clostridium acetobutylicum, known for its excellent capability of producing ABE (acetone, butanol, and ethanol) solvent,(More)
BACKGROUND Mandelic acid (MA), an important component in pharmaceutical syntheses, is currently produced exclusively via petrochemical processes. Growing concerns over the environment and fossil energy costs have inspired a quest to develop alternative routes to MA using renewable resources. Herein we report the first direct route to optically pure MA from(More)
There is an urgent need for vaccine against enterohemorrhagic Escherichia coli (EHEC), which causes a wide range of life-threatening diseases in human and animals. E. coli secreted protein A (EspA), intimin and shiga toxin (Stx) are important pathogenic factors and protective antigens of EHEC. In our previous study, we found that recombinant trivalent(More)
The color prediction of fluorescent ink security printing is a very concerned issus in the field of security printing quality control. This paper first analyzed the light transmission of solid fluorescent ink prints.We make the assumption that the absorption of ink layer and the the radiation of fluorescence are all occur on a very thin layer in the middle(More)
