Exploring Optimal Strategy of Microbial Fuel Cell-Assisted Bioremediation of Textile Dyes

摘要

According to our novel quantitatively revealing synergies gained from microbial fuel cell (MFC)-aided dye decolorization for biodegradation, this work optimized electron transfer (ET) characteristics for maximal performance of dye decolorization via simultaneous bioelectricity generation and dye decolorization (SBG&DD). The findings indicated that appropriate accumulation of decolorized metabolites of textile dyes could significantly facilitate both rates of BG and DD. However, higher dye concentration seemed to be more favorable to electron distribution dominated for color removal. As indicated, the most promising mode of MFC-aided pollutant degradation should be batch or plug flow reactor operating at low conversions for optimal dye decolorization.
