Fig. 4From: The effect of enhanced acetate influx on Synechocystis sp. PCC 6803 metabolismPhotosynthetic activity of the cyanobacterial strains. Relative oxygen evolution capacity of Synechocystis sp. PCC 6803 acetate transporter expression strain (AT; red bars) in comparison to the control strain (CS; blue bars) grown for eight days in MC1000 under continuous low light (20 μmol photons m−2 s−1). a Light-saturated oxygen evolution of PSII measured in the presence of artificial electron acceptor DCBQ. b Light-saturated whole chain net photosynthesis from water to NaHCO3. The oxygen evolution capacity was calculated as µmol O2 produced h−1 (mL cell culture)−1 at OD750 = 1. The mean and standard deviation represent three biological replicatesBack to article page
