Table 2. Comparison of the efficiency of photosynthesis.

Comparison of the efficiency of photosynthesis in terms of moles of photons required for biomass production in Synechocystis calculated from growth simulations in a 380 ml vessel of the PBR upon acclimation for 24 h at 50, 200, 300, 500, 800 and 950 μmol photons m⁻² s⁻¹ of orange–red light. Shown are: I_in (μmol photons m⁻² s⁻¹), light intensity available to the PBR domains; μh⁻¹, growth rate per hour; g DW L⁻¹, biomass density in gram dry weight per liter; g DW/mol photons, growth yield in mol photons absorbed per gram biomass.
