光合细菌在微生物燃料电池中的应用研究进展

Progress on application of photosynthetic bacteria in microbial fuel cells

微生物燃料电池(Microbial fuel cells,MFCs)降解污染物的同时产生电能,受到广泛关注。光合细菌在MFCs领域的应用实现了污水处理、CO2捕捉、光电转换等多重功能,并显示出了良好的产电特性。本文根据光合细菌在MFCs中所起作用的不同对其产电机理进行评述,并在此基础上分析了光照对光合细菌型MFCs产电性能的影响;针对当前研究的不足与面临的问题,提出了今后光合细菌在MFCs领域的应用前景与发展方向。

Microbial fuel cells （MFCs） are receiving wide attentions as a promising method of producing electricity through degradation of pollutants by microorganism. MFCs with photosynthetic bacteria as biocatalyst showed high capability of electricity generation, and achieved multiple functions of sewage treatment, capture of carbon dioxide, conversion of light energy into electricity, as well as recycling of valuable photosynthetic bacteria biomass. Based on the role of photosynthetic bacteria in the system, the ability of electricity production and electron transfer mechanism were reviewed. Moreover, the effects of light on the performance of MFCs inoculated with photosynthetic bacteria were also discussed. Finally the perspective of application of photosynthetic bacteria in MFCs was proposed.
