This study explored dye decolorization and bioelectricity generation of indigenous Proteus hauseri ZMd44 for dye-bearing wastewater treatment. Chemical structures of azo dyes apparently affected the performance of dye biodecolorization. Additions of diazo dye C.I. reactive blue 160 (RBu160) stimulated simultaneous dye decolorization and bioelectricity generation of ZMd44 in single chamber microbial fuel cells (MFCs). However, high-level additions of RBu160 repressed capabilities of power production in MFC due to competition of electrons used for reductive decolorization. Decolorized intermediates of RBu160-phenyl methadiamine and 5-sulfoanthranilic acid as electron shuttles might mediate electron transport for current generation in MFC.
本研究探索了土著变形菌 ZMd44 对偶氮染料的脱色和生物电能产生性能，用于处理含染料废水。偶氮染料的化学结构明显影响染料的生物脱色性能。重氮染料 C.I. 活性蓝 160（RBu160）的添加刺激了 ZMd44 在单室微生物燃料电池（MFC）中同时进行染料脱色和生物电能产生。然而，由于用于还原脱色的电子的竞争，RBu160 的高水平添加抑制了 MFC 中的发电能力。RBu160 的脱色中间产物苯基甲二胺和 5-磺基邻氨基苯甲酸作为电子穿梭体，可能介导了 MFC 中的电子传递以产生电流。
