As decolorized intermediates could play a role of electron-shuttling mediator to enhance the performance of dye decolorization and bioelectricity generation, this study selected model compounds with auxochromes (e.g., benzene-1,2-diol, 1,2-diaminobenzene) to explore how chemical structure(s) affected color removal and power producing capabilities in microbial fuel cells (MFCs). According to cyclic voltammetry, respiratory testing and MFC data, promising electron-shuttling capabilities of aforementioned compounds were revealed using Proteus hauseri ZMd44, Aeromonas sp. C78, Acinetobacter johnsonii NIUx72 bearing MFCs. These findings clearly indicated that chemical structure(s) of decolorized mediators directly affected characteristics of simultaneous reductive decolorization and bioelectricity generation in MFCs, suggesting feasible operation strategy of MFCs for industrial applications.
作为脱色中间体,它们可以作为电子穿梭介体来增强染料脱色和生物电能产生的性能。本研究选择带有助色团的模型化合物(如苯-1,2-二醇、1,2-二氨基苯),以探索化学结构如何影响微生物燃料电池(MFC)中的脱色和产电能力。根据循环伏安法、呼吸测试和 MFC 数据,使用 Proteus hauseri ZMd44、Aeromonas sp. C78 和 Acinetobacter johnsonii NIUx72 负载的 MFC 揭示了上述化合物具有良好的电子穿梭能力。这些发现清楚地表明,脱色介体的化学结构直接影响 MFC 中同时还原脱色和生物电能产生的特性,这为 MFC 在工业应用中的可行操作策略提供了依据。
