Figure 4From: High cell density media for Escherichia coli are generally designed for aerobic cultivations – consequences for large-scale bioprocesses and shake flask culturesGrowth curves and anaerobic metabolite concentrations in fed-batch cultivations of E. coli W3110 in the STR-PFR system with (△ and dashed line) or without (□ and solid line) addition of the trace elements selenium, nickel and molybdenum. (A) Specific growth rate and optical density; (B) accumulation of formate, (C) acetate, (D) lactate, (E) succinate, and (F) ethanol. Time of feed start is set to zero hours.Back to article page
