Abstract The role of ferric chloride (FC) on the reduction of antibiotic resistance genes (ARGs) in anaerobic digestion (AD) system was investigated from the perspective of vertical (VGT) and horizontal gene transfer (HGT) network through the high-throughput qPCR (HT-qPCR). Although FC showed limited impacts on methane production in AD of swine manure, the tetracycline and MLSB resistance genes were specifically reduced at the end, where tetQ of antibiotic target protection and ermF of antibiotic target alteration contributed the most to the reduction. Both VGT and HGT network were divided into three modules, and the complexity of HGT network was largely reduced along with AD, where the HGT connection was reduced from 683 (Module III) to 172 (Module I), and FC addition could further reduce the relative abundance of ARG hosts in Module I. The contribution of VGT and HGT to the changes of ARGs in AD was further deciphered, and although the VGT reflected by the changes of microbial community contributed the most to the dynamics of ARGs (68.0 %), the HGT contribution could further be reduced by the FC addition. This study provided a new perspective on the fate of ARGs response to the FC addition in the AD system.
