Optimization of CO₂ Supply for the Intensive Cultivation of Chlorella sorokiniana IPPAS C-1 in the Laboratory and Pilot-Scale Flat-Panel Photobioreactors.

ABSTRACT: Microalgae are increasingly being used for capturing carbon dioxide and converting it into valuable metabolites and biologically active compounds on an industrial scale. The efficient production of microalgae biomass requires the optimization of resources, including CO₂. Here, we estimated the productivity of Chlorella sorokiniana IPPAS C-1 depending on CO₂ concentrations and the ventilation coefficient of the gas-air mixture (GAM) in flat-panel photobioreactors (FP-PBRs) at laboratory (5 L) and pilot (18 L) scales. For the laboratory scale, the PBRs operated at 900 µmol quanta m^-2 s^-1 and 35.5 ± 0.5 °C; the optimal CO₂ flow rate was estimated at 3 mL CO₂ per 1 L of suspension per minute, which corresponds to 1.5% CO<
