摘要

本研究使用染料中間物之模式芳香胺中間物，來刺激含染料廢水脫色及生物產電之可行性。循環伏安圖譜指出部分偶氮染料脫色中間物具有電子梭之能力，添加於微生物燃料電池可促進其脫色效果及產電效能，並在此條件下進行比較研究結果表示微生物燃料電池添加實際染料脫色代謝物確實可有效刺激生物降解作用。研究中並探討染料脫色中間物(DMs)在以MFC為手段下，如何進一步有效刺激總電子通量，在連續操作下更可進行經濟可行之生物能源電池刺激最適化染料脫色操作。

This study revealed the feasibility of simultaneous bioelectricity generation and dye decolorization (SBG&DD) of microbial fuel cells (MFCs) in salty media. With supplementation of decolorized intermediates (DIs), MFCs significantly enhanced the performance of SBG&DD. Due to supplementation of DIs, electron-transporting characteristics of microbes effectively increased the electron-transfer flux in MFCs. By adding various species of DIs at different levels, optimal stimulation of DIs to SBG&DD could be achieved. This also significantly increased color removal efficiencies. Apparently, DI-augmented MFCassisted bioremediation seemed to be the most promising strategy to resolve operation disadvantages of dye decontamination in salty media. The approach provided effective alternatives to improve decolorization of textile dyes and suggested strategies for bioremediation of recalcitrant organics.
