Fig. 4From: Pyruvate production using engineered Escherichia coli Effects of culture conditions on pyruvate production. E. coli strain LAFCPCPt-accBC-aceE was cultivated for 24 h in N5G medium. Shown are the effects of temperature (a), culture pH (b), stirrer speed (c), and airflow rate (d) on pyruvate production. Error bars indicate SE (n = 3)Back to article page
