From: Development of an industrial yeast strain for efficient production of 2,3-butanediol
Endogenous and engineered 2,3-BDO production in yeast. A Endogenous mitochondrial 2,3-BDO synthesis pathway and engineered heterologous cytosolic 2,3-BDO production pathway in S. cerevisiae. B Production of 2,3-BDO from glucose by the PDC-negative strain HGS4 engineered with the 2,3-BDO synthesis pathway. C Production of 2,3-BDO from glucose by the PDC-negative strain HGS7 overexpressing bdhA. The fermentation was performed in 50Â ml medium in a static fermentation tube
