Fig. 1From: Isolation and characterization of Chlorella sp. mutants with enhanced thermo- and CO2 tolerances for CO2 sequestration and utilization of flue gasesEffects of different CO2 concentrations on the growth and photosynthesis rates of the wild type and mutants 283 and 359 of Chlorella vulgaris ESP-31. a Growth curves under 5% CO2. b Growth curves under 25% CO2. c Biomass productivity. d Net photosynthesis rates. A 50-mL culture of each strain aerated with different CO2 (0.1 vvm) was grown in BG-11 at 28 °C under 12 h light–dark (light intensity 150 μmol m−2 s−1) conditions for 4 days. Data shown are the means (along with the standard deviations) of at least two independent experimentsBack to article page
