Fig. 3From: Metabolic engineering of Synechocystis sp. PCC 6803 for the improved production of phenylpropanoidsSpecific production titer of tCA (A) and pCou (B) of Synechocystis strains during photoautotrophic growth. 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
