Autotrophic growth of the Synechocystis PCC 6803 (A and B) and Anabaena PCC 7120 (C and D) strains with light intensities of 30 μmol photons m−2 s−1 (A and C), 5 μmol photons m−2 s−1 (B), and 10 μmol photons m−2 s−1 (D). Cells were cultured in BG11 medium at 30°C, and the growth was determined by monitoring the optical density at 730 nm (OD730). sll0860-sll0861-com, complemented with sll0860-sll0861; mlla-1-com, complemented with omega-P6803rbcL-mlla-1 or omega-P7120rbcL-mlla-1; murQ-com, complemented with omega-P6803rbcL-murQ or omega-P7120rbcL-murQ.
