Production of Carotenoids and Phospholipids by Thraustochytrium sp. in Batch and Repeated-Batch Culture.

ABSTRACT: The carotenogenic thraustochytrid Thraustochytrium sp. RT2316-16 was grown in batch and repeated-batch cultures using different feeds containing glucose, or glycerol, and yeast extract, for the production of lipids, phospholipids and carotenoids. RT2316-16 produced canthaxanthin, astaxanthin and β-carotene. The effects of biotin, ascorbic acid, light and temperature were evaluated in some of the experiments. In 2-day-old batch cultures, the combined mass percentage of eicosapentaenoic acid and docosahexaenoic acid in total lipids was between 16.5% (glycerol-based medium in the dark; biomass concentration = 4.2 ± 1.1 g L^-1) and 42.6% (glucose-based medium under light; biomass concentration = 3.3 ± 0.1 g L^-1), decreasing to 3.8% and 6.1%, respectively, after day
