Key Points

This research aims to explore how microplastics and tetracycline affect antibiotic resistance genes during anaerobic digestion of sludge.
Examined the performance of anaerobic digestion under mesophilic conditions
Investigated the enrichment of antibiotic resistance genes
Analyzed the interactions between microplastics and tetracycline
Identified potential hosts for low-abundance bacteria that may harbor antibiotic resistance genes
Observed combined effects of microplastics and tetracycline on sludge digestion efficiency

Abstract

The combined impact of MPs and TC on ARG enrichment in sludge during mesophilic AD, where low-abundance bacteria may serve as potential hosts, warrants greater attention.
