(A) H2 and O2 production of C. reinhardtii strain cy6Nac2.49 (red) and it is parental wild-type (black) under photoheterotrophic conditions on TAP medium under a light/dark regime at light intensities of 50 W·m−2 and 10 W·m−2. Cultures were left under an air atmosphere in sealed vials at the start of the experiment and were not sparged with argon during the experiment. The maximum photosynthetic yields were measured at different light intensities (B) 50 W·m−2 and (C) 10 W·m−2 respectively, where Fv/Fm represents the maximum fluorescence emission recorded in the dark periods, while δFv/Fm’ represents the maximum fluorescence value recorded during illumination. Shaded and not shaded sections represent dark (14 h) and light (10 h) periods respectively.
