Abstract

Thraustochytrium sp. ATCC 20892 produced high yields of docosahexaenoic acid (DHA), more than four other strains of Thraustochytrium and Schizochytrium tested, but insignificant amounts of other polyunsaturated fatty acids. Glucose and sodium glutamate were the preferred carbon and nitrogen sources, respectively, and the optimum conditions for growth and DHA production were pH 7.0 at 25°C with 40 g glucose 1-1 for 4 days. Temperature profiling under these optimum conditions further enhanced the yield and volumetric productivity of DHA.
