Abstract

The invention provides bacillus subtilis Pro-N2 as well as application and a product thereof, and belongs to the technical field of microorganisms. The preservation number of the bacillus subtilis Pro-N2 provided by the invention is CGMCC (China General Microbiological Culture Collection Center) No. 17882. The bacillus subtilis Pro-N2 as well as the fermentation liquor and the product of the bacillus subtilis Pro-N2 have relatively strong intestinal tract colonization capability, can rapidly improve microbial balance in host intestinal tracts, can be applied to foods or food additives and feeds or feed additives, and are simple in preparation method and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a bacillus subtilis and its application and products. Background technique [0002] Bacillus subtilis is a species of Bacillus. Its single cell is 0.7-0.8×2-3 microns, and the coloring is uniform. Uncapsulated, with periosteum flagella, able to move. Gram-positive bacteria can form endogenous stress-resistant spores. The spores are 0.6-0.9×1.0-1.5 microns, oval to columnar, located in the center of the bacterium or slightly biased, and the bacterium does not expand after spore formation. Bacillus subtilis grows and reproduces quickly. The surface of the colony is rough and opaque, stained white or slightly yellow. When growing in a liquid medium, it often forms wrinkles. It is an aerobic bacterium. [0003] Bacillus subtilis can use protein, various sugars and starch to decompose tryptophan to form indole. Active substances such as subtilisin, polymyxin, ny...
