Abstract

The invention provides a mutant strain of Schizochytrium and its application, relates to the technical field of marine microorganism application, and is used for increasing the growth rate of Schizochytrium strains. Wherein, the Schizochytrium limacinum mutant strain (Schizochytrium limacinum) was deposited in the General Microbiology Center of the China Committee for the Collection of Microorganisms, with a preservation date of October 22, 2015, and a preservation number of CGMCC No.11534. The mutant strain of Schizochytrium has the traits of fast growth, high content of oil and DHA, and the traits are stable. The aforementioned mutant strain of Schizochytrium can be used for large-scale production of oil or DHA.

Description

technical field [0001] The invention relates to the technical field of application of marine microorganisms, in particular to a mutant strain of Schizochytrium and its application. Background technique [0002] Schizochytrium is a marine algae-like fungus belonging to the class Labyrinthulomycota, Labyrinthulomycetes, Thraustochytriales, Thraustochytriaceae . Schizochytrium is generally unicellular and spherical. Schizochytrium can accumulate a large amount of active substances useful to the human body, such as oil, DHA (docosahexaenoic acid), etc., and is a good source of oil and DHA production. [0003] However, the growth rate of the existing Schizochytrium strains is slow, resulting in low biomass yield, which hinders the large-scale industrialization process of Schizochytrium. Contents of the invention [0004] The invention proposes a mutant strain of Schizochytrium and its application to improve the growth rate of the Schizochytrium strain. [0005] To achieve t...
