  • Patent number: 7033584
    Abstract: A process is provided for growing microflora of the order Thraustochytriales such as Thraustochytrium, Schizochytrium, and mixtures thereof, in fermentation medium containing non-chloride containing sodium salts, in particular sodium sulfate. In a preferred embodiment, the process produce, microflora having a cell aggregate size useful for the production of food products for use in aquaculture. Further provided is a food product which includes Thraustochytrium, Schizochytrium, and mixture thereof, and a component selected from flaxseed, reapedeed, soybean and avocado meal. Such a food product includes a balance of long chain and short chain omega-3 highly unsaturated fatty acids. A method for increasing omega-3 highly unsaturated fatty acid content of eggs by feeding a feed to poultry. The feed contains the microorganisms of the order Thraustochytriales having a omega-3 highly unsaturated fatty acid content of more than 6.7 percent of total cell dry weight.

  • Patent number: 6399803
    Abstract: This invention is directed to a process for separating a first triglyceride comprising a docosahexaenoic acid residue from a second triglyceride. The process comprises introducing a feed mixture comprising the first triglyceride and the second triglyceride into a chromatographic separation zone, and then isolating a fraction of the feed mixture in the separation zone that has a mass ratio of the first triglyceride to the second triglyceride that is greater than in the feed mixture. The separation zone comprises a stationary phase which comprises metal ions that are capable of coordinating with a double bond of a fatty acid residue of the first triglyceride to form a metal complex with the fatty acid residue.

  • Patent number: 6395778
    Abstract: This invention is directed to a process for making an enriched mixture comprising a polyunsaturated fatty acid ester having the Formula (V): In one embodiment, this process comprises transesterifying an oil from Schizochytrium sp. with an alcohol in the presence of a base to form a saturated fatty acid ester and the polyunsaturated fatty acid ester (the fatty acid esters are formed from the alcohol and fatty acid residues of at least one glyceride in the oil). Urea is subsequently dissolved in a medium comprising the fatty acid esters to form a medium comprising the fatty acid esters and dissolved urea. This medium is then cooled or concentrated to form (a) a precipitate comprising urea and at least a portion of the saturated fatty acid ester, and (b) a liquid fraction comprising at least most of the polyunsaturated fatty acid ester. Afterward, the precipitate and liquid fraction are separated.

  • Patent number: 6177108
    Abstract: A process for the heterotrophic or predominantly heterotrophic production of whole-celled or extracted microbial products with a high concentration of omega-3 highly unsaturated fatty acids, producible in an aerobic culture under controlled conditions using biologically pure cultures of heterotrophic single-celled fungi microorganisms of the order Thraustochytriales. The harvested whole-cell microbial product can be added to processed foods as a nutritional supplement, or to fish and animal feeds to enhance the omega-3 highly unsaturated fatty acid content of products produced from these animals. The lipids containing these fatty acids can also be extracted and used in nutritional, pharmaceutical and industrial applications.
