Application method and preparation method of a kind of bacteriostatic microbial fermentation agent

Abstract

The invention belongs to the technical field of microorganisms, and in particular relates to an application method of a bacteriostatic microbial starter and a preparation method thereof. The bacteriostatic type microbial fermentation agent contains Bacillus pumilus, Bacillus licheniformis, Saccharomyces bradis, Enterococcus faecium, Streptococcus thermophilus and Lactobacillus acidophilus, and the number of live bacteria is 1.05×10 10 ~1.5×10 10 cfu / g. After the fermented agent prepared by the present invention is used for fermentation, antibacterial substances are produced in the fermented feed, and the fermented bacteria themselves also have antibacterial effects, which can realize the purpose of antibiotic substitutes, and the fermented agent of the present invention can improve the utilization rate of feed materials , promote animal growth, can ferment and improve the nutritional value of low-value agricultural and sideline products, and alleviate the problem of human and livestock competition for food.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a bacteriostatic microbial starter and a preparation method thereof. Background technique [0002] Antibiotics have created huge economic benefits for the aquaculture industry. Antibiotics have been widely used as feed growth-promoting additives. However, due to the widespread use of antibiotics in livestock and poultry feed, especially excessive use, various pathogenic microorganisms are resistant to antibiotics, and animals Double infection will seriously affect the health of livestock and poultry; at the same time, it will cause drug residues in livestock and poultry products, which will not only affect the quality and safety of livestock and poultry products, but also cause pathogenic microorganisms in humans to develop resistance to antibiotics, thereby directly threatening Human health: In the past 20 to 30 years, the rate of drug-resistant strains has be...

[0002] Antibiotics have created huge economic benefits for the aquaculture industry. Antibiotics have been widely used as feed growth-promoting additives. However, due to the widespread use of antibiotics in livestock and poultry feed, especially excessive use, various pathogenic microorganisms are resistant to antibiotics, and animals Double infection will seriously affect the health of livestock and poultry; at the same time, it will cause drug residues in livestock and poultry products, which will not only affect the quality and safety of livestock and poultry products, but also cause pathogenic microorganisms in humans to develop resistance to antibiotics, thereby directly threatening Human health: In the past 20 to 30 years, the rate of drug-resistant strains has been increasing, and it has become more and more difficult for humans to treat bacterial infectious diseases. Strengthening, antibiotic-free breeding is the general trend of the future development of the breeding industry. Therefore, microbial fermented feed uses the metabolism and reproduction of microorganisms to produce or prepare feed with many advantages such as green, safe and efficient.
