Abstract:
1. A process for producing microbial lipids comprising: a) growing microorganisms of the order Thraustochytriales in a fermentation medium comprising a carbon source and a nitrogen source to increase the biomass density of the fermentation medium to at least 100 g/L on a dry cell weight basis, wherein: b) limiting a nutrient source other than carbon in the fermentation medium to induce lipid production by the microorganisms after reaching a biomass density of 100 g/L, while maintaining a biomass density of at least 100 g/L on a dry cell weight basis; wherein the primary use of the carbon source by the microorganisms is to produce lipids after induction of lipid production and when the biomass density of the fermentation medium is at least 100 g/L on a dry cell weight basis; and c) recovering the lipids, wherein greater than about 15% of the lipids are polyunsaturated lipids.
