摘要
抗生素在畜禽养殖中被广泛用于治疗动物感染,但动物体并不能完全代谢吸收抗生素,大部分抗生素随着尿液、粪便排出体外释放到环境中,导致抗生素残留和抗性基因污染。本文综述了畜禽养殖中抗生素的使用现状、抗生素残留的危害,总结了降解抗生素的纯培养微生物及其降解机理,讨论了抗生素降解菌在堆肥中的应用,展望了微生物降解抗生素的发展前景,以期为畜禽养殖废弃物中抗生素污染的治理提供参考。
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.
