【Abstract】 Docosahexaeonic acid( DHA) is an important kind of ω-3 polyunsaturated fatty acid,which has been widely used in infant food additive and pharmaceutical industry. Bio-production of DHA-rich oil is the hot topic in recent research. This paper reviewed the common producing strains,product safety assessment and bio-production of DHA,especially the enhancement of DHA production by Schizochytrium sp.,and technology innovation of lipid refining. Furthermore,combined with current status of domestic industrialization of DHA,the prospect of DHA-rich oil was also analyzed in this paper,which would provide the reference for the development of other value-added lipid-soluble chemicals.更多还原
