Table 1 Comparison of specific growth rate, specific glucose uptake rate and D-LA yield between L. bulgaricus WT and ET45

From: Evolutionary engineering of Lactobacillus bulgaricus reduces enzyme usage and enhances conversion of lignocellulosics to D-lactic acid by simultaneous saccharification and fermentation
