Oxidation stability and cold fluid property are important factors in the quality of biodiesel. Monounsaturated fatty acids (MUFAs) are suitable fatty acids for biodiesel when considering the low temperature fluidity and oxidative stability in regards to the biodiesel fuel standards. In this study, MUFA productivity of Phaeodactylum tricornutum MBEyh07L (KCTC18366P), isolated from coastal seawater of Young-Heung Island, Incheon, Korea, was investigated. The biomass was produced using bubble column photobioreactors in modified f/2-Si medium prepared with natural seawater. The highest MUFA productivity obtained was 28.5 mg/L/d. MUFAs accounted for 43.1% of the total fatty acids produced whereas saturated fatty acids and polyunsaturated fatty acids accounted for 26.0% and 18.0% of the total fatty acids, respectively. The result implies that the lipids from P. tricornutum MBEyh07L may contribute to improve the oxidation stability and cold flow property of biodiesel. |
