Progress on application of photosynthetic bacteria in microbial fuel cells

Abstract:

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.
