Problems solved by technology

At present, physical and chemical methods such as high temperature and high pressure, strong acid and strong alkali, and extrusion are usually used to treat feathers. The process is complicated, consumes a lot of energy, and is easy to cause environmental pollution.
Most of the feather-degrading bacteria isolated at present are not ideal for degrading feathers, and most microorganisms still need some pre-treatment to degrade feathers. It is more practical to screen microbial strains that can efficiently degrade natural feathers

Abstract

The invention discloses Bacillus paramycoides. The nucleotide sequence of the Bacillus paramycoides is shown in SEQ ID No. 1. The invention provides Bacillus paramycoides and the gene sequence of theBacillus paramycoides, in addition, the Bacillus paramycoides is utilized to degrade feathers, the degradation efficiency is high, no pre-treatment of the feathers is needed before degradation, and nopollution to the environment is caused in the degradation process.

Description

technical field [0001] The invention relates to the technical fields of biology and genetic engineering, in particular to a bacillus pseudomycoides. Background technique [0002] In recent years, my country's poultry breeding industry has developed rapidly. Feathers can account for 5%-7% of the weight of broilers, and the annual output exceeds 1 million tons. Waste, and seriously pollute the environment, and even spread diseases, causing Newcastle disease, air bag inflammation and keratoconjunctivitis. health problems. Feathers are rich in keratin, the content of crude protein can reach more than 85%, and the amino acid composition is relatively complete, and the content of cysteine ​​is the most among all natural feeds. But keratin is a kind of "water-insoluble hard protein" rich in disulfide bonds and stable in structure. At present, physical and chemical methods such as high temperature and high pressure, strong acid and alkali, and extrusion are usually used to treat fe...
