Progresses and Prospects of Microbial Fuel Cell in Analytical Applications

微生物燃料电池(Microbial fuel cell,MFC)是一种利用微生物将化学能直接转化为电能的装置。近年来,除改善微生物燃料电池的输出性能外,研究者也不断开发其在传感分析中的应用。基于微生物燃料电池的传感分析装置无需外加电源,具有操作简单、可连续检测等优点,是一种极具应用前景的传感分析技术。本文依据这些传感分析装置的用途进行分类,主要综述了微生物燃料电池在检测分析生化需氧量(BOD)、挥发性脂肪酸、毒性物质、微生物活性和数量以及其它方面的研究,并对其发展趋势和应用前景进行了展望。

Microbial fuel cell( MFC) is a type of energy device in which exoelectrogens are harnessed for directly converting the chemical energy of organic matter into electric energy. In addition to researches on the development of high-performance MFC,we have witnessed a rapid progress in the analytical application of MFCs. The MFC-based biosensors are simple and easy to operate,and they can also be used to monitor target online without external power sources,thus attracting more and more attention. Here,we summarize and discuss the progress on using MFCs for measuring biological oxygen demand( BOD),volatile fatty acids,pollutant and toxic compounds,microbial activities and other substances. Furthermore,the design principle of MFC-based biosensors is clarified. The outlook and future prospect of MFC-based biosensors are also discussed in the end.
