Enhancement of Lipid Production of Chlorella pyrenoidosa Cultivated in Municipal Wastewater by Magnetic Treatment

Abstract

Abstract. Despite the significant breakthroughs in research on microalgae as a feedstock for biodiesel, its production cost is still much higher than that of fossil diesel. One possible solution to overcome this problem is to optimize algal growth and lipid production in wastewater. The present study examines the feasibility of using magnetism treatment for algae lipid production enhancement when do outdoor cultivation of Chlorella pyrenoidosa. In this study, the effect of magnetic field intensity and treatment time on algal growth and lipid production was determined. Results indicated that magnetic treatment enhanced biomass and lipid production of C. pyrenoidosa by 14.87% and 29.79%. It was concluded that magnetism treatment is an efficient method for algae lipid production enhancement.
