| abstract |
A process is provided 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. Corrosion in a fermentor is reduced by obtaining microorganisms such as those of the genus Thraustochytrium or Schizochytrium from a saline environment and growing the microorganisms in the fermentor in a culture medium containing sodium ions provided by a non-chloride sodium salt such that the chloride concentration in the medium is less than about 3 grams chloride per liter. |
