Fermentation production technique of schizogenesis chytrid

Abstract

The invention provides a fermentation production technique of schizogenesis chytrid, which solves the problems of lower yield and higher production cost in the prior art. The fermentation production technique has the technical scheme that bean pulp is taken as main nitrogen source for fermentation production, and the technique comprises the steps of bean pulp hydrolysis, pressing filter, preparation of fermentation medium, arrangement of a fermentation tank system, collection and drying of the schizogenesis chytrid, and preparing the schizogenesis chytrid dry powder. The new fermentation production technique of the schizogenesis chytrid takes the bean pulp as main nitrogen, thus not only reducing the cost of fermentation production, but also improving the growth rate of the schizogenesis chytrid and promoting fatty acid accumulation of the cells of the schizogenesis chytrid.

Description

technical field

[0001] The invention belongs to the field of microbial fermentation production, and in particular relates to a fermentation production process of Schizochytrium with soybean meal as the main nitrogen source. Background technique

[0002] In recent years, the important role of polyunsaturated fatty acids (PUFAs) on human health has been paid more and more attention. Among them, docosahexaenoic acid (22:6, n-3, docosahexaenoic acid, DHA), one of the important ω-3 PUFAs, is favored because of its important physiological functions in humans and animals. Studies have shown that DHA is the basic component of cell membranes in some tissues of the human body, plays an important role in the development of the baby's visual system and nervous system, and also has pharmacological effects such as lowering cholesterol, anticoagulation, and preventing cancer. In addition, DHA is also an essential fatty acid required for the growth and development of various seawater fish,...
