Nitrilases have found wide use in the pharmaceutical industry for the production of fine chemicals, and it is important to have a method by which to screen libraries of isolated or engineered nitrilase variants (including bacteria and fungi). The conventional methods, such as high-performance liquid chromatography, liquid chromatography-mass spectrometry,(More)
A novel Gram-positive, strictly anaerobic, spore-forming, rod-shaped bacterium, designated strain S11-3-10T, was isolated from the pit mud used for Chinese Luzhou-flavor liquor production. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the strain formed a monophyletic clade with the closely related type strains of Clostridium cluster(More)
A critical step in the synthesis of the rare sugars, L-lyxose and L-ribose, from the corresponding D-sugars is the oxidation to the lactone. Instead of conventional oxidizing agents like bromine or pyridinium dichromate, it was found that a heterogeneous catalyst, Pd-Bi/C, could be used for the direct oxidation with molecular oxygen. The composition of the(More)
