Abstract

This study provided a novel evaluation scheme to quantitatively reveal "synergistic" stimulation of microbial fuel cell (MFC)-assisted dye decolorization for industrial practicability. This work also disclosed why dye decolorization was more electrochemically favorable during simultaneous bioelectricity generation and dye decolorization (SBG&DD). Quantitative assessment upon stimulating effects of different decolorized metabolites on BG and DD alone was also implemented for conclusive remarks. Apparently, using MFC as the method of dye decontamination could considerably increase ca. 40-70% of electron transfer capabilities for SBG&DD, thereby significantly improving the performance of dye decontamination.

Keywords: Bioelectricity generation; Microbial fuel cell; Reductive decolorization.
