Strings of Electron-Carrying Proteins May Hold The Secret to 'Electric Bacteria'

Scientist Moh El-Naggar studies bacteria that construct membrane wires to 'breathe' rock. This three-dimensional construct depicts a wire composed of spherical vesicles containing electron-transporting proteins (red and green).

Could a unique bacterium be nature's microscopic power plant? Scientist Moh El-Naggar and his team think it's possible. They work with the Shewanella oneidensis species of bacteria, one of a group of microbes that essentially "breathe" rocks. As part of their metabolism, the bacteria
