Highlights Biochar enhanced microbes’ metabolic activity by adsorbing TCE and intermediate products allowing them to be degraded on its surface. While biochar itself cannot remove As, it acted as carrier to remove As-laden microorganisms, achieving 70% As-removal from groundwater. Biochar enhanced the self-detoxification ability of microorganisms for As by enriching microbes possessing crucial As-transforming genes.
