Klebsiella oxytoca stains are excellent 2,3-butanediol producers. To use this strain in industry area, 2,3-butanediol must be produced more than now. In order to achieve a high production, the optimization of fermentation condition is necessary. Among the various factors for 2,3-BDO fermentation, pH is the most important factor affecting 2,3-BDO production. 2,3-BDO production was measured in time, performing the fermentation with pH control and non-controlled pH at different initial pH values(5, 6, 7). 2,3-BDO was more produced without pH control than with pH control. Increasing pH values, 2,3-BDO was producued less but organic acid was produced more. Especially, 2,3-BDO was not yielded in the medium with pH maintained at 7. Metabolic flux analysis was perfored and the different results were shown according to the variable pH conditon. In conclution, pH is the important variable affecting 2,3-BDO metabolic pathway.
