| Abstrak | This study investigated the ability of microalgae to reduce the emission of CO2 from the atmosphere. Airlift photobioreactor used in this investigation in order to cultivate Chaetoceros gracilis in batch and close system. The experiments were conducted by two different initial cell numbers, 10,000 and 40,000 cells / mL respectively..Carbon dioxide with concentration of 12% and flow rate 0.5 mL/minute were injected into the reactor and monitored its reduction. It can be found that the trend of growth rate shown similar results with Wu and Merchuk(1), but its value was smaller than that obtained by Sutomo(2). As increasing of initial cell number from 10.000 and 40.000 cells / mL, carbon dioxide reduction increased slightly. Generally, both experiments shown that at the first day injection, the concentration of CO2 in the gas holder reduced significantly by 4% (from 12% to 8%), indicating that high gas holdup was occurred in the riser. This concentration decrease gradually by 50% after 5 days and 75% after 8-9 days due to utilization of CO2 in photosynthesis. |
