Abstract

Marine baceteria of fish interstines were screened for high eicosapentaenoic acid(EPA) productivity. An isolated bacteria, KS-90, identified and designated as Allteromonus putrefaciens KS-90. A. putrefaciens KS-90 was found to be a rich source of EPA production and it was observed on incuibation at 4~12.5$^{\circ}C$ and pH 7.0. The production of EPA reached 18mg/g of dry cell weight when A. putrefaciens KS-90 was grown in the medium containing 1.0% pepton, 0.5% yeast extract, 0.025% meat extract and 2.0% glucose in 1/2 concentration of an artificial seawater, pH for 48 hr at $25^{\circ}C$. This value accounted for 24.7% of the total fatty acid in the extractable lipids.
