ABSTRACT

Microalgae culture is now growing interest because of it can be cultivated on non-agricultural land using wastewater along with CO2 that can be obtained from fossil fuel combustion. Also microalgae are contains high oil and starch making possible the production of good quality biodiesel. Thus, algae culture can contribute to CO2 fixation, wastewater treatment and can be a source of bio-energy. As in the Middle East countries especially in Saudi Arabia region huge amount of CO2 emitted from industrial and automobile sources (power plant, desalination, cement). Due to the scarcity of sweet water, reuse of wastewater also a necessary with minimum energy and costs. With targeting the CO2 mitigation and wastewater treatment Chlorella Vulgaris were cultured in batch photo-bioreactors. The six different CO2 concentrations of 2%,
4%, 6%, 8%, 10% and 12% in Air are used to study the effect of growth kinetics, cell density and dry biomass production rate. Results of the finding used for optimize operating parameters for culture developing of Chlorella Vulgaris with maximum CO2 utilization.
