2,3-butanediol (2,3-BDO) can be chemically changed into butadiene which is an important precursor of synthetic rubber, thus the production of 2,3-BDO have been attracting attention continuously in scholar circle. It can be produced by fermenting several bacteria such as Enterobacter asburiae. However, different culture conditions will affect the production and productivity of 2,3-BDO. For example, under different pH values, the productivity of 2,3-BDO from glucose vary a lot. As well, different substrate concentrations will also influence the final results of 2,3-BDO production due to the potential possibility of substrate inhibition effect. In this work, fermentation experiments by a new Enterobacter asburiae strain under different pH control conditions from 5 to 8 have been conducted to examine the influence on 2,3-BDO productivity. Also, different initial glucose concentrations have been also examined in the experiment to observe the substrate shortage condition and substrate inhibition condition and the optimized substrate concentration for producing 2,3-BDO by Enterobacter asburiae was determined by the experimental results.
