Abstract
Nine thraustochytrid strains isolated from subtropical mangroves were scree ned for their eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) pr oduction potential in a glucose yeast extract medium. Their ability to util ize okara (soymilk residue) for growth and EPA and DHA production was also evaluated. EPA yield was low in most strains, while DHA level was high on g lucose yeast extract medium, producing 28.1-41.1% of total fatty acids, for all strains, with the exception of Ulkenia sp. KF13. The DHA yield of Schi zochytrium mangrove! strains ranged from 747.7 to 2778.9 mg/l after 52 h of fermentation at 25 degreesC. All strains utilized okara as a substrate for growth, but DHA yield was lower when compared with fermentation in a gluco se yeast extract medium.
