Abstract Fermentation for EPA production by diatom Nitzschia laevis under different mediums was investigated.As a result, the basic medium was selected,which is 8LDM that is enhanced the concentration of nutritions 7 times. By applying 8LDM medium, the EPA yield reached 93.22mg/L. This result was 4.24 times and 4.36 times to f/2 and LDM, respectively.
