1.1.1.4 synthesis increase in production of (R,R)-butanediol from xylose in batch and continuous cultures by increase of temperature from 30 to 39°C, analysis of byproducts 655087 1.1.1.4 synthesis Paenibacillus brasilensis produces 2,3-butanediol (2,3-BDO) and can be utilized for large scale production -, 760411 1.1.1.4 synthesis the enzyme is useful in production of 2,3-butanediol, an important starting material for the manufacture of bulk chemicals such as methyl ethyl ketone and 1,3-butadiene -, 685764 1.1.1.4 synthesis two coexpressed enantiocomplementary carbonyl reductases, BDHA (2, 3-butanediol dehydrogenase from Bacillus subtilis) and GoSCR (polyol dehydrogenase from Gluconobacter oxydans) are used for asymmetric reduction of 2-hydroxyacetophenone (2-HAP) to (R)-1-phenyl-1,2-ethanediol ((R)-PED) or (S)-1-phenyl-1,2-ethanediol ((S)-PED) with excellent stereochemical selectivity and coupled with cofactor regeneration by GDH. Enantiomerically pure (R)-1-phenyl-1,2-ethanediol ((R)-PED) can be used as a building block for the preparation of (R)-norfluoxetine, (R)-fluoxetine, and beta-lactam antibiotics -, 761565
