Abstract

The invention provides a method for culturing clostridium butyricum through mixed fermentation, and belongs to the technical field of microbial culture. The method includes the following step that single-bacterium culture solutions of clostridium butyricum, bacillus subtilis, yeast and lactic acid bacteria are mixed for mixed culture, wherein the temperature of mixed culture is 29 DEG C, the pH value of mixed culture is 6.4-6.8, the time for mixed culture is 16-20 hours, the rotating speed of mixed culture is 150-170 rpm, and the mixing ratio of clostridium butyricum to yeast to bacillus subtilis to lactic acid bacteria is 1:1:3:1. The method is simple to operate, the biological activity of cultured clostridium butyricum is remarkably improved, and the biological activity is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of microorganism culture, and in particular relates to a method for culturing Clostridium butyricum by mixed fermentation. Background technique [0002] The rapid development of science and technology has significantly improved the living standards of human beings, and the increasingly prominent environmental protection and food safety issues have attracted more and more attention. The antibiotics that were favored by the aquaculture and feed industries earlier are gradually being replaced by greener and safer probiotics. As a member of the new probiotics family, Clostridium butyricum has a very broad market prospect for the aquaculture industry and other related industries. [0003] Clostridium butyricum is a non-resident, spore-forming probiotic that exists in the intestines of humans and animals, and is also widely distributed in leaves, soil, cheese, and natural yogurt. Inactivation), acid resistance (...
