Paper Title:
High Power Generation by a Strain of Facultative Anaerobe in Double-Chamber Microbial Fuel Cell
  Abstract

Microbial Fuel Cells (MFCs) are systems that can convert chemical energy into electrical energy by biological oxidation, current effort to improve the power output is limited by the lack of knowledge about the electrochemical activity bacteria and researches on the power generation mechanisms of pure strains are rare. In this study, the exoelectrogenic (”exo” for exocellular) bacterium staphylococcus SJ-1 was directly isolated from the MFC, which was stably run for 90 days. Cyclic Voltammetry (CV) indicated that temporary mediator produced by SJ-1 may take the work of transferring electron. A new built double-chamber MFC was inoculated with pure SJ-1, and after 40 days enrichment, the system produced 520mW/m2 power density and the highest open circuit voltage (OCV) reached to 616mV, the power output was higher than most of the single-strain MFCs reported.
