Popis: This study evaluates the performance of alkaliphilic microalgae Ankistrodesmus falcatus in the Bicarbonate-based Integrated Carbon Capture and Algae Production System (BICCAPS). The system utilized bicarbonate as carbon source for microalgae production. BICCAPS parameters such as pH, algal biomass productivity and CO2 utilization (inorganic carbon conversion, Ci) were observed at different sodium bicarbonate (NaHCO3) loading concentration and type of culture media. The highest productivity was observed at 10 g/L of NaHCO3 loading in BRSP medium at 3.5539 mg/L/day. This value is 30% lower compared to the control experiment (continuously aerated bioreactor). The Ci values of the different system ranges from 1.17 x 10-4 to 1.51 x 10-4 moles/L/day. Both the pH of the BRSP and NPK media at 10 g/L and 30g/L loading of NaHCO3 increased through time. The result shows that A. falcatus has a potential in BICCAPS utilization.
