Progress in metabolic mechanism of docosahexenoic acid production by fermentation

Abstract:

Docosahexenoic acid (DHA) is an important polyunsaturated fatty acid which is beneficial to human health. Compared with the DHA derived from fish oil, DHA by microbial production possesses many advantages, and has a bright prospect. In this article, we reviewed strains, metabolic pathway, key enzymes and mechanism of lipid accumulation for microbial production of DHA. Those information would be greatly helpful for further improving DHA production by metabolic engineering.
