Fig. 3From: Enhanced productivity of extracellular free fatty acids by gene disruptions of acyl-ACP synthetase and S-layer protein in Synechocystis sp. PCC 6803Growth curve (A), oxygen evolution rate (B), chlorophyll a content (C), and carotenoid content (D) of WT, KS, KA, and KAS Synechocystis sp. PCC 6803 strains cultured in BG11 medium for 14 days. In (A), (C), and (D), the error bars represent standard deviations of means (mean ± S.D., n = 3). In (B), the oxygen evolution rate was measured using log phase-growing cells (5 days). Data represent mean ± S.D., n = 3. Means with the same letter are not significantly different with the significance level at P < 0.05Back to article page
