Fig. 3From: Targeted optimization of central carbon metabolism for engineering succinate production in Escherichia coli Deletion of sdh and iclR, and co-overexpression of pck-ecaA increased succinate production. Error bars represent SD for three replicates. Asterisks indicate p-values (**p < 0.01, *p < 0.05) in which BKS9 and BKS10 were compared to BKS8 and BKS11 was compared to BKS10Back to article page
