In modern ecological systems, the overuse and misuse of antibiotics have escalated prevalence antibiotic resistance genes (ARGs) mobile genetic elements (MGEs), positioning them as emerging environmental contaminants. Notably, composting serves a sustainable method to recycle agricultural waste into nutrient-rich fertilizer while potentially reducing ARGs MGEs. This study conducted 47-day experiment using pig manure corn straw, supplemented with chitin N-Acetyl-D-glucosamine, explore impact these additives on dynamics MGEs, unravel interplay between microbial communities in composting. Results showed that adding 5% significantly postponed thermophilic phase, yet enhanced removal efficiency total MGEs by over 20% compared control. Additionally, addition N-Acetyl-D-glucosamine increased abundance tetracycline-resistant sulfonamide-resistant genes, well High-throughput sequencing revealed bacterial α-diversity, providing diverse hosts for Resistance mechanisms, predominantly efflux pumps deactivation, played pivotal role shaping resistome process. Co-occurrence network analysis identified key phyla Proteobacteria , Firmicutes Gemmatimonadota Myxococcota transformation dissemination. Redundancy indicated physicochemical factors, particularly carbon-to-nitrogen ratio emerged critical variables influencing The findings lay foundation developing regulation reduce risks animal composts.
