Time-course changes in photosynthetic activity in indoor PBR. The photosynthetic O2 evolution (A) and PSII activity (F v′/F m′) (B) of wild type and mutant M4 of Chlorella sp. GD were determined in indoor PBR aerated with ambient air or 6% CO2 at 40 °C under 200 μmol/m2/s illumination. The data are expressed as the mean ± SD (n = 3) and different letters indicate significant difference between the culture times (P < 0.05)
