stereoisomeric composition analysis of 2,3-butanediol produced by strain 10-1-A using gas chromatography. Strain 10-1-A produces a mixture of (2R,3R)-2,3-butanediol and meso-2,3-butanediol with a ratio of nearly 1:1. As (3R)-acetoin is the major source of (2R,3R)-2,3-butanediol and meso-2,3-butanediol, a meso-butanediol dehydrogenase and a (2R,3R)-2,3-butanediol dehydrogenase are co-present in strain 10-1-A
