Oxygen evolution and ECS measurements. Net oxygen evolution (A and B) and ECS decay rates (indicating proton fluxes across the thylakoid membrane; C and D) for cells grown in TAP (A and C) and HS (B and D) media. C and D are presented as per 10⁹ cells instead of 10⁶ used in the rest of the manuscript. Results for cells cultured at 160 μmol m⁻² s⁻¹ are indicated by empty diamonds, 40 μmol m⁻² s⁻¹ by empty squares, 15 μmol m⁻² s⁻¹ by empty triangles, 5 μmol m⁻² s⁻¹ by filled diamonds, and 0 μmol m⁻² s⁻¹ by filled squares. Error bars indicate sd (n = 3).
