Growth of the Synechocystis strains under different conditions. a Growth under light. The cells were cultivated under 20 μmol photons m⁻² s⁻¹ for 8 days and induced with 2.5 µM of NiCl₂ every second day. b Growth under light with acetate. The cells were cultivated as for (A), with addition of 0.2% acetate every second day. c Growth in darkness with acetate. The cells were cultivated in the dark with addition of 2.5 µM of NiCl₂ and 0.2% acetate every second day during 8 days. Error bars represent the mean ± SE
