Reduction in ARGs and Mobile Genetic Elements Using 2-Bromoethane Sulfonate in an MFC-Powered Fenton System.

ABSTRACT: The integration of an MFC-powered Fenton (MFC-Fenton) system into the traditional anaerobic composting process can promote excess dewatered sludge (ES) decomposition. However, the antibiotic resistance gene (ARG) profiles in ES treated by MFC-Fenton systems remain poorly understood; in addition, the effect of adding 2-bromoethane sulfonate (BES, a methane inhibitor) during ES treatment using an MFC-Fenton system on ARG levels is largely unexplored. The present work focused on investigating the effects of BES and bioelectrochemical processes on ARG and MGE abundances and unraveling the ARG attenuation mechanism. According to our findings, adding BES promoted ARG reduction in ES in an MFC-Fenton system. The average ARG levels in the MFC-Fenton samples containing high BES contents (0.4 or 0.5
