Growth, product formation, and calculated total rates of carbon fixation of the two product-forming mutants, compared to the wild-type strain Synechocystis sp. PCC6803. a Growth and product formation of the wild-type (WT) and the two product-forming strains (SAA012 and SAW041). b Total carbon fixation rate of SAA012, SAW041, and the corresponding WT Synechocystis strain plotted against the cell density of the culture. Data are mean ± SD of three biological replicates.
