Metagenomic insights into suppressing antibiotic-resistant bacteria in mesocosm-scale constructed wetlands: calamus-biochar alleviates selective pressure and disrupts genetic co-occurrence network.
As a mainstream technology for the advanced treatment of wastewater treatment plant effluents, constructed wetlands (CWs) exhibit limited efficiency in antibiotic removal and may instead serve as reservoirs for antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB). To address this, a mesocosm-scale...
