Abstract
Disclosed is a process for growing the microflora Thraustochytrium, Schizochytrium, and mixtures thereof, which includes the growing of the microflora in fermentation medium containing non-chloride containing sodium salts, in particular sodium sulfate. In a preferred embodiment of the present invention, the process produces microflora having a cell aggregate size useful for the production of food products for use in aquaculture. Further disclosed is a food product which includes Thraustochytrium, Schizochytrium, and mixtures thereof, and a component selected from flaxseed, rapeseed, soybean and avocado meal. Such a food product includes a balance of long chain and short chain omega-3 highly unsaturated fatty acids.
Claims20
A process for culturing a microorganism of the order Thraustochytriales for the production of lipids, the process comprising:
- culturing the microorganism of the order Thraustochytriales in a culture medium that comprises a chloride concentration of less than about 500 mg/L and a non-chloride source of sodium selected from the group consisting of soda ash, sodium carbonate, sodium bicarbonate, sodium sulfate and mixtures thereof, and wherein the microorganism after culturing has a sterol content of at least about 0.1% ash-free dry weight (afdw) and a cholesterol content of at least about 15% of the total sterol content.
