主要研究方向及内容

Main Research area and subject

The research direction focuses on bioenergy and renewable resource utilization. Based on two microbial platforms, "Enterobacter aerogenes" and "Klebsiella", metabolic pathway design has been conducted for the biosynthesis of C4 platform chemicals (succinic acid, ethylene glycol, 1,3-propanediol, and 2,3-butanediol), C1 chemicals (acetyl-CoA derived chemicals, and ethanol), as well as CO2 fixation.
