Abstract

The invention discloses a Bacillus subtilis L1, and an application thereof in the degradation of lincomycin residual in lincomycin residues. The application is characterized in that the lincomycin residues are inoculated with a fermentation solution obtained by fermenting and culturing the Bacillus subtilis L1, and are cultured at 25-37 DEG C under 80-220 rpm to realize the degradation of lincomycin in the residues. The Bacillus subtilis L1 can degrade the lincomycin residual in lincomycin residues, and the lincomycin degradation rate within 6 days reaches 95.39%; and microorganisms for degrading antibiotics also can be used for degrading antibiotics in tap water or soil.

Description

technical field

[0001] The invention relates to a strain and a method for harmlessly treating lincomycin in lincomycin fermentation residue, belonging to the field of environmental protection. Background technique

[0002] my country is a major producer of antibiotics, with an annual output of more than 140,000 tons of major antibiotics, and an annual output of more than 1.4 million tons of solid waste (mycelium and protein), namely antibiotic residues, produced during antibiotic production.

[0003] Antibiotic residues are solid fermentation wastes produced in the process of fermenting and producing antibiotics. A small amount of antibiotics is a special kind of hazardous waste. If it is not disposed of properly, it will cause potential harm to the ecological environment and human health. The harm has the characteristics of concealment, lag, accumulation, synergy and jointness.

[0004] There are a small amount of residual antibiotics and their degradation products in anti...
