SCIENCE - Clean electricity from bacteria? Researchers make breakthrough in race to create 'bio-batteries'

Scientists have made an important breakthrough in the quest to generate clean electricity from bacteria. New findings show that proteins on the surface of bacteria can produce an electric current by simply touching a mineral surface. The research shows that it is possible for bacteria to lie directly on the surface of a metal or mineral and transfer electrical charge through their cell membranes. This means that it is possible to 'tether' bacteria directly to electrodes - bringing scientists a step closer to creating efficient microbial fuel cells or 'bio-batteries.'
