Effects of culture medium on growth kinetics and fatty acid composition of Chlorella sp. T12
Many factors affect the growth performance of microalgae, especially culture medium impacts growth rate and fatty acid composition. Thus, the aims of this study were to investigate the effects of various culture media including NSIII, Chu No.10, BG11 and BBM on the growth kinetics, biomass product...

| description | Many factors affect the growth performance of microalgae, especially culture medium impacts growth rate and fatty
acid composition. Thus, the aims of this study were to investigate the effects of various culture media including NSIII, Chu
No.10, BG11 and BBM on the growth kinetics, biomass productivity, lipid content, lipid productivity and fatty acid profiles of
cultivated Chlorella sp.T12. The Chlorella sp.T12 was cultured at 25±2 ºC temperature under continuous 3,500 Lux light
intensity for 14 days. The culture in BBM medium allowed the highest of the specific growth rate (0.83±0.69 d-1
), biomass
productivity (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 percentage
of unsaturated fatty acid (67.56%). The unsaturated fatty acid meet requirement of fatty acid composition that suitable for
biodiesel 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 medium
choice for cultivating Chlorella sp.T12 to provide high productivity of biomass and lipids that can be used in biodiesel. NSIII
was the best medium choice for cultivating Chlorella sp.T12 for pharmaceutical and cosmetic production. |
