Photosynthesis rates of WT and Δgox #46 mutant at increasing concentrations of externally supplied dissolved inorganic carbon (DIC). Cells were cultivated under HC conditions (5% CO₂) and O₂ evolution was measured using a Clark electrode. For LC measurements, cells were shifted for 24h to LC conditions (0.04% CO₂). The photosynthetic rate was analysed according to increasing DIC concentration in the medium. Fitting analysis was performed using the Michaelis–Menten Kinetic (Prism 5) on the basis of three biological replicates each.
