Knockout of iclR and ackA for overcoming acetate excretion. a Time profiles for the cell biomass, glycolate production and acetate production of iclR konckout strain E. coli BL21(DE3) iclR::Kan/pLMe2/pLMa2 (Q2741) under fed-batch cultivation. b Time profiles for the cell biomass, glycolate production and acetate production of the ackA knockout strain E. coli BL21(DE3) ackA::Kan/pLMe2/pLMa2 (Q2742) under fed-batch cultivation. Strains were cultivated in a 3 L laboratory fermenter containing 1 L of fermentation medium. Error bars represent ± standard deviation from the mean
