Bioelectricity production from paper industry waste using a microbial fuel cell by Clostridium species

Renewable energy is an increasing need in our society. Microbialfuel cell (MFC) technology represents a new form of renewableenergy by generating electricity from what would otherwise beconsidered waste. It is possible to directly generate electricity-using bacteria while accomplishing wastewater treatment in processesbased on microbial fuel cell technologies. When bacteria oxidize asubstrate, they remove electrons. Electric current generation is madepossible by keeping bacteria separated from oxygen, but allowingthe bacteria growing on an anode to transfer electrons to the counterelectrode (cathode) that is exposed to air. In this report, thecellulosic waste was utilized for the bioelectricity production byClostridium acetobutylicum and Clostridium thermohydrosulfuricum.
