Abstract

Relative growth rate and fatty acid compositions of Phaeodactylum tricornutum UTEX640 were examined. The glgae were grown under different initial NaNO 3 concentrations (75, 375, 750, 1 125, 1 500 and 1 875 mg/L) and harvested at the late exponential phase. The culture temperature was 22±1 ℃; the salinity was adjusted to 28 by distilled water. The results showed that the optimum NaNO 3 concentration for the highest relative growth rate was 1 125 mg/L. The optimum NaNO 3 concentration for the highest EPA content was 1 875 mg/L.
