Popis:	The effects of trace elements on the lipid productivity and fatty acid composition ofNannochloropis oculata (N. oculata)were studied. The results showed that trace elements had a strong influence on not only the lipid productivity but also the fatty acid composition. The addition of Fe3+, Zn2+, Mn2+, Mo6+, and EDTA and the deletion of Cu2+and Co2+can increase the lipid productivity. The optimum concentrations of the trace elements in the culture medium are 6 times of Fe3+and EDTA, the same concentration of Zn2+, Mn2+, and Mo6+as the control group, but the optimum medium has no Cu2+or Co2+. Fe3+, Zn2+, Mn2+, Mo6+, and EDTA are indispensable during the EPA formation ofN. oculata. The addition of Fe3+, Zn2+, Mn2+, Mo6+, and EDTA can strongly increase the content of EPA in the lipid ofN. oculata, but the concentration of the trace elements had little influence on the level of EPA.
