Production of Eicosapentaenoic Acid (20:5 n-3) by Vibrio pelagius Isolated from Turbot (Scophthalmus maximus (L.)) Larvae

摘要

Fourteen bacterial strains isolated from turbot, Scophthalmus maximus (L.), larvae were screened for eicosapentaenoic acid (20:5 n-3) (EPA) production. Gas chromatography analysis revealed that one bacterial species, Vibrio pelagius, contained a high proportion of EPA in cellular lipid. This finding was confirmed by gas chromatography-mass spectrometry analysis. A higher concentration of EPA was detected when the bacterium was cultured at 4°C.
