• ARGs were detected in livestock manure, sludge, food waste and fermentation dregs. • The succession of microbial community is an important factor affecting ARGs. • Horizontal transfer mechanism of ARGs during composting should be further studied. Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However, the effect of composting in removing ARGs from organic solid waste has recently become controversial. Thus, this article summarizes and reviews the research on ARGs in relation to composting in the past 5 years. ARGs in organic solid waste could spread in different environmental media, including soil and the atmosphere, which could widen environmental risks. However, the conventional composting technology had limited effect on ARGs removal from organic solid waste. Improved composting processes, such as hyperthermophilic temperature composting, could effectively remove ARGs, and the HGT of ARGs and the microbial communities are identified as vital influencing factors. Currently, during the composting process, ARGs were mainly affected by three response pathways, (I) “Microenvironment-ARGs”; (II) “Microenvironment-microorganisms-ARGs”; (III) “Microorganisms-horizontal gene transfer-ARGs”, respectively. Response pathway II had been studied the most which was believed that microbial community was an important factor affecting ARGs. In response pathway III, mainly believed that MGEs played an important role and paid less attention to eARGs. Further research on the role and impact of eARGs in ARGs may be considered in the future. It aims to provide support for further research on environmental risk control of ARGs in organic solid waste.  相似文献

本文基于我国近海典型底栖双壳类生物毛蚶、紫贻贝急性和慢性毒性效应实验数据,分析了重金属汞对受试生物体质量、体长及消化腺超氧化物歧化酶(superoxide dismutase, SOD)酶活力的影响,获取了无观察效应浓度(No Observed Effect Concentration, NOEC),并以生存率为反应终点分析计算了重金属汞的非检测毒性效应浓度及半致死浓度。结果表明,各实验组SOD酶活力的组内方差与组间方差的差异整体上并不显著(P > 0.05),实验周期内仅在个别时间处理组间存在显著性差异(P < 0.05);实验周期内毛蚶和紫贻贝体质量、体长的组内方差与组间方差并没有显著性差异(P > 0.1),体长及体质量不适合作为毒性效应的评价终点。重金属汞对毛蚶、紫贻贝的非检测毒性效应浓度分别为23.7 μg·L-1、87.8 μg·L-1,半致死浓度分别为683.4 μg·L-1、773.2 μg·L-1。  相似文献
