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.

74. 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 3 grams of chloride per liter of said culture medium and that comprises 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 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. - View Dependent Claims (75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94)
