Abstract

The invention discloses a Schizochytrium sp.TIO1101 strain with high-yield DHA (docosahexaenoic acid) and a fermentation method thereof. The Schizochytrium sp.TIO1101 strain provided by the invention has a preservation number of CGMCC (China General Microbiological Culture Collection Center) No.4603. After the Schizochytrium sp.TIO1101 is subjected to high-density heterotrophic fermentation for 72h, the biomass liveweight, the lipid content and the DHA are respectively 120g / L, 54.3% and 51.4% of the content of total lipid, therefore the Schizochytrium sp.TIO1101 has development and application values extremely. The Schizochytrium sp.TIO1101 disclosed by the invention has the advantages that: the Schizochytrium sp.TIO1101is obtained through separation; the high-density heterotrophic fermentation of the Schizochytrium sp.TIO1101 is realized; and the lipid extracted from the Schizochytrium sp.TIO1101 cells obtained under the fermentation condition has high DHA content and purer components.

Description

technical field

[0001] The invention relates to a high-yield DHA-producing Schizochytrium strain and a fermentation method thereof. Background technique

[0002] Docosahexaenoic acid (DHA) mainly exists in the gray matter of the human brain and the retina. It is an essential fatty acid component to maintain the normal physiological metabolism of the human body. It has a very important physiological role in the development of the brain and vision of infants and young children. Vascular disease, improve human immunity, etc. DHA has aroused great interest and been widely used because of its unique physiological regulation function.

[0003] The traditional source of DHA is deep-sea fish oil, but polyunsaturated fatty acids (PUFAs) extracted from fish oil have problems such as unstable yield, low yield, high cost, and other ω-6PUFAs. Nervous, traditional DHA resources have been unable to meet the growing market demand. Therefore, the development of new resources of DHA has be...
