EXOELECTROGENIC BACTERIA THAT POWER MICROBIAL FUEL CELLS PDF

Abstract. There has been an increase in recent years in the number of reports of microorganisms that can generate electrical current in microbial fuel cells. There has been an increase in recent years in the number of reports of microorganisms that can generate electrical current in microbial fuel cells. Although many. The use of microbial fuel cells to generate electrical current is increasingly being seen as a viable source of renewable energy production. In this Progress article.
