Carbonaceous materials can accelerate extracellular electron transfer for the biotransformation of many recalcitrant,redox-sensitive contaminants and have received considerable attention in fields related to anaerobic bioremediation.As important electron shuttles (ESs),carbonaceous materials effectively partic-ipate in redox biotransformation processes,especially microbially-driven Fe reduction or oxidation cou-pled with pollutions transformation and anaerobic fermentation for energy and by-product recovery.The related bioprocesses are reviewed here to show that carbonaceous ESs can facilitate electron transfer be-tween microbes and extracellular substrates.The classification and characteristics of carbon-containing ESs are summarized,with an emphasis on activated carbon,graphene,carbon nanotubes and carbon-based immobilized mediators.The influencing factors,including carbon material properties (redox po-tential,electron transfer capability and solubility) and environmental factors (temperature,pH,substrate concentration and microbial species),on pollution catalytic e～ciency are discussed.Furthermore,we briefly describe the prospects of carbonaceous ESs in the field of microbial-driven environmental reme-diation.
