L-Glutamate production by C. glutamicum WT (pEKEx3) (open columns) and WT(pEKEx3- bioYMN ) (closed columns). L-Glutamate concentrations in the culture supernatant (upper panel), biomass yields (g cell dry weight formed per g glucose consumed; middle panel) and product yields (g L-glutamate formed per g glucose consumed) of three fermentations in minimal medium with 40 g/l glucose, 25 μM IPTG and 1 μg/l biotin are given as means with standard deviations.
