Abstract:

Antibiotics are widely used in animal husbandry for the treatment of animal infections. However, animals cannot completely metabolize and absorb antibiotics, and most of the antibiotics are released into the environment with urine and feces, which leads to antibiotic residues and contamination of antibiotic resistance genes. In the present assay, we reviewed the usage of antibiotics in livestock and poultry breeding and the hazards of antibiotic residues, and summarized the pure culture of microorganisms which could degrade antibiotics and the degradation mechanisms. Furthermore, the applications of antibiotics-degrading bacteria in composting were discussed, and the development prospects of microbial degradation of antibiotics were explored, to provide references for the treatment of antibiotic pollution in livestock and poultry breeding wastes.

Key words: livestock and poultry waste, antibiotics, microbial degradation
