ABSTRACT
This chapter demonstrates that the research towards sustainable power generation using cyanobacteria as a catalyst. In photosynthetic-microbial fuel cell (p-MFC), microorganisms are able to generate electrons through both catabolism and photosynthesis process. Apart from biofuel production, microalgae is utilised for production of electrical energy using p-MFC. Researchers are looking for new catalysts which will be able to generate electricity without emission of carbon dioxide during their utilization at MFC. Electricity or biofuel derived from microbial photosynthetic organisms has been recognised as an emerging technology to contribute a substantial amount of renewable energy. The length of bacterial pili is in the range of nanometres, although the electrical conduction range can be extended into the micrometer scale through networks of pili between cells. These length scales illustrate the importance of biofilm over the electrode, which is responsible for microbial exoelectrogenic activity.
