Microbial production of meso-2,3-butanediol by metabolically engineered Escherichia coli under low oxygen condition.

Zheng-Jun Li et al.

Applied microbiology and biotechnology, 87(6), 2001-2009 (2010-05-26)

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

Production of 2-butanol through meso-2,3-butanediol consumption in lactic acid bacteria.

Payam Ghiaci et al.

FEMS microbiology letters, 360(1), 70-75 (2014-09-02)

2-Butanol has been an issue of industries in many areas, for example, biofuel production (as an advanced alternate fuel), fermented beverages, and food (as taste-altering component). Thus, its source of production, the biological pathway, and the enzymes involved are of

Efficient (3S)-Acetoin and (2S,3S)-2,3-Butanediol Production from meso-2,3-Butanediol Using Whole-Cell Biocatalysis.

Yuanzhi He et al.

Molecules (Basel, Switzerland), 23(3) (2018-03-23)

(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

Medium optimization and proteome analysis of (R,R)-2,3-butanediol production by Paenibacillus polymyxa ATCC 12321.

Jinshan Li et al.

Applied microbiology and biotechnology, 97(2), 585-597 (2012-08-07)

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

Inhibition of acetate accumulation leads to enhanced production of (R,R)-2,3-butanediol from glycerol in Escherichia coli.

Xiaolin Shen et al.

Journal of industrial microbiology & biotechnology, 39(11), 1725-1729 (2012-07-27)

This work describes the production of (R,R)-2,3-butanediol in Escherichia coli using glycerol by metabolic engineering approaches. The introduction of a synthetic pathway converting pyruvate to (R,R)-2,3-butanediol into wild-type E. coli strain BW25113 led to the production of (R,R)-2,3-butanediol at a
