Fig. 6From: Metabolic engineering of Synechocystis sp. PCC 6803 for the improved production of phenylpropanoidsSpecific production of tCA (A) and pCou (B) during photoautotrophic growth of Synechocystis PRM8-based strains. Values are the means of three biological replicates and two technical replicates, error bars represent the standard deviation. Statistically significant differences were examined by Student’s t-test and are represented by an asterisk (*P < 0.05)Back to article page
