A vertical photobioreactor containing the microalgae Scenedesmus obliquus is a highly efficient system for converting carbon dioxide (CO2) into biomass. The use of photobioreactor for CO2 mitigation has been explored using microalgae as photosynthetic microorganism. The growth rate (m, h-1) were 0.03; 0.13; 0.20; 0.09 at treatment of 0%, 2%, 5% and 7% pure CO2 supplied, respectively during 16 days experiment. The maximum dried biomass (gr ml-1) was 1.7 at 2% pure CO2. The highest CO2 removal effiency (%) was 34 at 2% pure CO2 supply. The results showed that the photobioreactor gave a high efficiency of CO2 removal by phototrophic microalgae culture.
