Abstract

About 5, 000 strains of marine microorganisms were screened for eicosapentaenoic acid (EPA)-producing ability, which was detected in 88 of them. All of the latter were found to be obligate aerobic, Gram-negative, motile, short rod-shaped bacteria. One strain, designated as SCRC-8132, showed a doubling time of 30min at 25°C and produced 20mg/iter (4mg/g dry cells) when cultured in a P-Y-M-Glucose medium for 18h. The EPA to total fatty acids ratio was 24%. The strain produced 26mg EPA/liter (15mg/g dry cells) when cultured at 4°C for 5 days, the EPA ratio being increased to 40%.
