Abstract
Present invention provides a method to efficiently manufacture an oil-containing product including long chain polyunsaturated fatty acid, or a high added value oil containing long chain polyunsaturated fatty acids. The method comprises culturing a microorganism belonging to the Genus Labyrinthula. The Labyrinthula microorganism is cultured in a medium containing oil or fatty acid as a carbon source, and the produced long chain polyunsaturated fatty acid is recovered from the culture. With the present invention, it is possible to efficiently produce from the vegetable oil and the like, an oil containing product comprising long chain polyunsaturated fatty acids such as docosahexanoic acid having a carbon number of 20 or more, and two or more unsaturated bonds, or an oil containing the long chain polyunsaturated fatty acid. Further, the method of the present invention may be used to reform oil by converting the plant oil and like to high added value oil containing the long chain polyunsaturated fatty acid.
