Electric microbes – X-ray diffraction has been used to reveal the structure of proteins attached to the surface of the microbe Shewanella oneidensis, a species found in deep-sea anaerobic habitats. These proteins can transfer electrons making this micro-organism potentially rather interesting as an electricity-generating system. The research could allow researchers to tether bacteria directly to electrodes creating efficient microbial fuel cells or bio-batteries powered by human or animal waste. Such an advance could also …
