A metabolically engineered Escherichia coli has been constructed for the production of meso-2,3-butanediol (2,3-BD) under low oxygen condition. Genes responsible for 2,3-BD formation from pyruvate were assembled together to generate a high-copy plasmid pEnBD, in which each gene was transcribed

(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

Paenibacillus polymyxa can produce the (R,R)-stereoisomer of 2,3-butanediol (2,3-BDL) which is industrially very useful. Two important factors affecting (R,R)-BDL production by P. polymyxa ATCC 12321, medium composition, and addition of acetic acid to the culture were investigated in this study
