摘要
针对如抗生素菌渣、畜禽粪便和污泥等固体废弃物中抗生素抗性基因(ARGs)污染问题,对传统好氧堆肥技术及外源添加物强化堆肥技术对ARGs的处理效果、好氧堆肥体系内重金属和细菌群落对ARGs消长的影响及微生物通过分子内部可移动遗传元件实现ARGs在不同微生物之间的水平传播进行了分析。发现不同重金属不同浓度下对多种ARGs的影响效果不同;对不同的ARGs与同一宿主菌之间的正相关表明了不同的ARGs的共存,进一步得出细菌群落演替可能是所有混合堆肥条件下ARGs降解的主要驱动力。
Aiming at the pollution of antibiotic resistance genes(ARGs) in solid wastes such as antibiotic residues, livestock and poultry manure, sludge, etc.,this article discussed the effects of traditional aerobic composting technology and enhanced composting technology with external additives on ARGs.The influence of heavy metals and bacterial communities in the oxygen composting system on the growth and decline of ARGs and the horizontal transmission of ARGs between different microorganisms by microorganisms through movable genetic elements within the molecules were analyzed.The study found that different heavy metals have different effects on multiple ARGs at different concentrations;the positive correlation between different ARGs and the same host bacteria indicates the coexistence of different ARGs, and further concluded that the bacterial community succession may be all mixed the main driving force for the different fates of ARGs under composting conditions.
