Abstract

The invention discloses Bacillus subtilis bred by a space mutation breeding technology. The strain is named Bacillus subtilis N9-1-35 and was collected in China Center for Type Culture Collection on August 31, 2011, and the collection number is CCTCC M2011301. The test shows that the Bacillus subtilis is an excellent probiotic strain. After entering intestinal tracts of animals, the Bacillus subtilis achieves the effects of a probiotic and can also generate a plurality of kinds of digestive enzymes in the growth and reproduction process of the animals, so that the digestion and absorption of the animals on feeds are improved, the conversion rate of the feeds is improved, and the cost of the feeds is reduced; and the Bacillus subtilis can be used for producing enzyme-producing probiotics, and is a strain which has excellent research and development value. The invention also discloses an enzyme-producing probiotic. The enzyme-producing probiotic consists of Bacillus subtilis powder, Streptococcus lactis powder, Lactobacillus acidophilus powder and corn starch.

Description

technical field

[0001] The invention relates to a bacillus subtilis bred by space breeding technology and its application, belonging to the field of biotechnology. Background technique

[0002] In the 21st century, people have higher and higher requirements for food safety and ecological environment, and the feed industry, which is at the forefront of the aquaculture industry, has generally attracted people's attention. The "1996-2020 China Feed Industry Development Strategy Research" promulgated by the National Feed Industry Office has clearly stated that "it is very urgent to replace the abuse of chemical synthetic substances such as feed antibiotics with green environmental protection products". The best way to replace these pollutants is to use biological technology. Microecological preparation is a modern high-tech product of biotechnology. It is a functional biological feed additive that organically combines probiotics, enzyme preparations, oligosaccharides, and biolo...
