Formula: C4H10O2, Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. In a document type is Article, and a compound is mentioned, 19132-06-0, Name is (2S,3S)-Butane-2,3-diol, introducing its new discovery.
(3S)-Acetoin and (2S, 3S)-2, 3-butanediol are important platform chemicals widely applied in the asymmetric synthesis of valuable chiral chemicals. However, their production by fermentative methods is difficult to perform. This study aimed to develop a whole-cell biocatalysis strategy for the production of (3S)-acetoin and (2S, 3S)-2, 3-butanediol from meso-2, 3-butanediol. First, E. coli co-expressing (2R, 3R)-2, 3-butanediol dehydrogenase, NADH oxidase and Vitreoscilla hemoglobin was developed for (3S)-acetoin production from meso-2, 3-butanediol. Maximum (3S)-acetoin concentration of 72.38 g/L with the stereoisomeric purity of 94.65% was achieved at 24 h under optimal conditions. Subsequently, we developed another biocatalyst co-expressing (2S, 3S)-2, 3-butanediol dehydrogenase and formate dehydrogenase for (2S, 3S)-2, 3-butanediol production from (3S)-acetoin. Synchronous catalysis together with two biocatalysts afforded 38.41 g/L of (2S, 3S)-butanediol with stereoisomeric purity of 98.03% from 40 g/L meso-2, 3-butanediol. These results exhibited the potential for (3S)-acetoin and (2S, 3S)-butanediol production from meso-2, 3-butanediol as a substrate via whole-cell biocatalysis.
