Abstract

2,3-Butanediol is an attractive product for biorefinery due to its various applications and industrial potential. Enterobacter aerogenes is also considered as a major 2,3-butanediol producer. This study is intended to enhance the production of 2,3-butanediol with addition of acetate into the culture media using E. aerogenes ATCC 29007 and to determine the mechanism of improved 2,3-butanediol production. 2,3-Butanediol production was increased by 34.2% with the addition of acetate in batch culture compared to that without acetate in 130 g/L of glucose. This increase was caused by buffering effects and upregulation of the transcription levels of genes involved in 2,3-butanediol production through acetate addition.
