Abstract | Many factors affect the growth performance of microalgae, especially culture medium impacts growth rate and fattyacid composition. Thus, the aims of this study were to investigate the effects of various culture media including NSIII, ChuNo.10, BG11 and BBM on the growth kinetics, biomass productivity, lipid content, lipid productivity and fatty acid profiles ofcultivated Chlorella sp.T12. The Chlorella sp.T12 was cultured at 25?2 ?C temperature under continuous 3,500 Lux lightintensity for 14 days. The culture in BBM medium allowed the highest of the specific growth rate (0.83?0.69 d-1), biomassproductivity (0.20?0.05 g/l/d), lipid content of the dry weight (14.434%) and lipid productivity (0.029?0.01 g/l/d) and percentageof unsaturated fatty acid (67.56%). The unsaturated fatty acid meet requirement of fatty acid composition that suitable forbiodiesel production. Although, the lipid content of cultivation in NSIII was the lowest, the percentage of saturated fatty acid(51.88%) was the highest that suitable for pharmaceutical and cosmetic production. Therefore, the BBM was the best mediumchoice for cultivating Chlorella sp.T12 to provide high productivity of biomass and lipids that can be used in biodiesel. NSIIIwas the best medium choice for cultivating Chlorella sp.T12 for pharmaceutical and cosmetic production. |
