Immobilized solid-phase humin on a graphite electrode set at -500 mV (vs. standard hydrogen electrode) significantly enhanced the microbial reductive dechlorination of pentachlorophenol as a stable solid-phase redox mediator in bioelectrochemical systems (BESs). Compared with the suspended system, the immobilized system dechlorinated PCP at a much higher efficiency, achieving 116 μmol Cl(-)g(-1) humin d(-1). Fluorescence microscopy showed a conspicuous growth of bacteria on the negatively… Expand
