Table 3 Maximum biomass, maximum biomass productivity, CO2 biofixation rate and specific growth rate of Chlorella vulgaris ESP-31 wild type and mutants under indoor and outdoor condition with simulated flue gas

From: Isolation and characterization of Chlorella sp. mutants with enhanced thermo- and CO2 tolerances for CO2 sequestration and utilization of flue gases
