Abstract

The invention discloses a novel bacillus strain X901 with a relatively strong bacteriostatic action and an application thereof. The preservation number of the strain is GDMCC No: 61472. The bacillus X901 strain is a new bacillus strain which is separated and identified for the first time in China and has bacteriostatic activity, and bacteriostatic substances can be generated in the whole culture process. The crude antibacterial product and the extracellular polysaccharide extract have a relatively obvious antibacterial effect on gram-negative bacteria (escherichia coli, haemophilus parasuis and aeromonas veronii) and gram-positive bacteria (staphylococcus aureus, streptococcus suis and bacillus subtilis). The strain has no drug resistance or drug resistance, has no pathogenicity when being orally taken, and is safe. In the breeding production of livestock and poultry, aquatic products and other animals, the strain can be used as a probiotic strain or a feed microbial additive, the use of antibiotics is reduced, the disease resistance of animals is improved, and the strain has very high application value.

Description

Technical field [0001] The present invention relates to the field of microorganisms, and more particularly to a new Bacillus X901 strain having a strong bacteriostatic action and its application thereof. Background technique [0002] At present, problems such as the residue of livestock and poultry products caused by antibiotic abuse have increased significant increase in drug resistance. my country is the largest antibiotic producer and the country in the world. It is also a hitting area of ​​antibiotics and bacterial resistance, especially the animal husbandry fields, and serious harmful people's food health. Under the advocacy of national defensance, farm tries to use substitutes, but the effect is not significant, so seeking feeding antibiotics is imminent. [0003] At present, in the existing feed additive, Bacillus, Bacillus, Bacillus, Bacillus, Bacillus, Bacillus, Bacillus, Bacillus, Bacillus, Bacillus, etc. The research and development significance of Bacillus Antibacteri...
