Summary

Minimizing the usage of glucose carbon for growth and cell maintenance energy requirement, specific glucose uptake rates, specific ethanol production rates were increased 5-fold. At 0.2 hr−1 and Yg = 0.007–0.009, ethanol production rates of 7.99–8.46 g/ltr/hr, Qp values of 14.85 g/g/hr were obtained. This relationship is discussed in regard to glucose fermentation efficiency.
