Interaction of temperature and CO2 concentration on algal growth in indoor PBR. The growth performance of Chlorella sp. GD wild type and mutant M4 was determined first under different temperatures for 4 days (A) and then under different CO2 concentrations at 25 °C (B) and 40 °C (C) for 4 days. The data are expressed as the mean ± SD (n = 3) and different letters indicate significant difference between the culture times (P < 0.05)
