Macro-micro scales insights into the effect of enrofloxacin on the Fe-C-Anammox system: Performance enhancement, metabolic optimization, and ARGs reduction

Key Points

• Performance enhancement observed in the Fe-C-Anammox system due to enrofloxacin treatment, optimizing its metabolic processes.
• Reduction of antibiotic resistance genes (ARGs) was significantly correlated with improved microbial productivity in the system.
• Observational analysis focusing on the interactions between enrofloxacin and the Fe-C-Anammox microbial processes in an environmental framework.
• Findings highlight a potential for improving wastewater treatment and mitigating antibiotic resistance in microbial communities.
