摘要： Antibiotic-degrading bacteria are commonly used to treat antibiotic contamination, but the antibiotic resistance genes (ARGs) they carry are often overlooked. This study used metagenomic assembly and binning analyses to explore potential antibiotic-degrading bacteria and their ARGs during pig manure composting. The result showed that 35 metagenome-assembled genomes (MAGs) mainly containing alkyl-aryl transferase and decarboxylase genes involved in the removal of antibiotics. Multidrug (12 4), beta-lactam (67), macrolide-lincosamide-streptogramin (MLS) (64), and tetracycline (43) were the central ARG types detected in the 35 MAGs. Furthermore, the risk of ARGs was evaluated using the arg_ranker framework, and 19 MAGs were found to contain intermediate-high-risk ARGs with human-associated-enrichment, gene transferability, and host pathogenicity. Bin 34 of the genus of Geofilum had the highest ARG risk. Bin 6, Bin 11 and Bin 14 of the genus of Limnochorda, Chelatococcus and Niabella, had a lower ARG risk and were considered as potential antibiotic-degrading bacteria.
