Growth performance in outdoor PBR. Biomass production (A) and appearance (B) of Chlorella sp. GD wild type and mutant M4 were determined in outdoor PBR aerated with 6% CO2. The data are expressed as the mean ± SD (n = 3) and different letters indicate significant difference between the culture times (P < 0.05). Air temperature (C), PBR temperature (D), irradiance outside PBR (E), and irradiance inside PBR (F) were recorded over culture period
