The widespread occurrence of tire particles (TPs) in soils has attracted considerable attention due to their potential threats. The assemblage of bacteria and associated antibiotic resistant genes (ARGs) on TPs is yet largely unknown, especially under the stress of soil pollutants. In the present study, TPs were incubated in soils with or without the stress of heavy metal (Cu2+) or/and antibiotic (tetracycline), and bacterial community and ARG profile on TPs and in soils were explored using high-throughput sequencing and high-throughput quantitative PCR. Results indicated that bacterial community structure on TPs was significantly different from the surrounding soils, with a lower diversity,..View full abstract
