Growth curves of wild-type, TAM-2, and TAM-4 mutants under autotrophic conditions. Wild-type was grown with TAM-2 (a) or TAM-4 (b) and the cell content was measured once a day. All experiments were performed in 1-L cylinders, illuminated with 450 μmol photons m^-2 s^-1, 25°C. Growths were performed in a semi-batch system fed with air/CO₂ mix; the CO₂ supply was modulated in order to keep the pH of the medium always below 7.1.
