Aerobic composting technology is an efficient, safe and practical method to reduce the residues of antibiotics and antibiotic resistance genes (ARGs) due to unreasonable disposal of livestock manure. Nowadays, it remains unclear how aerobic composting works to minimize the level of remaining antibiotics and ARGs in manure. Moreover, aerobic composting techniques even have the potential to enhance ARGs level. Therefore, this study conducted a literature review on ARGs variation during the composting process to assess the fate, migration, and risk features of antibiotics and ARGs in different livestock manure and compost. The relationship between ARGs reduction and crucial factors (temperature, heavy metal, and microbial community structures) in the composting process was discussed. The merits and limitations of different technologies used in compost was summarized. The effects on ARGs reduction in the aerobic composting process with various strategies was examined. We attempt to provide a fresh and novel viewpoint on the advancement of global aerobic composting technology.
好氧堆肥技术是一种高效、安全、实用的方法，可以减少由于不合理处理动物粪便而导致的抗生素和抗生素抗性基因（ARGs）的残留。目前，好氧堆肥技术如何最大限度地减少粪便中残留抗生素和 ARGs 的水平仍不清楚。此外，好氧堆肥技术甚至有可能提高 ARGs 的水平。因此，本研究对堆肥过程中 ARGs 变化进行了文献综述，以评估不同动物粪便和堆肥中抗生素和 ARGs 的命运、迁移和风险特征。讨论了 ARGs 减少与堆肥过程中关键因素（温度、重金属和微生物群落结构）之间的关系。总结了堆肥中不同技术的优缺点。研究了各种策略对好氧堆肥过程中 ARGs 减少的影响。我们试图为全球好氧堆肥技术的发展提供一个新的视角。
