Bacteria, which are one of the essential organisms in healthy soil, have been shown to “eat” electricity and transfer it to metals or other solid surfaces, producing a stream of electricity. An experiment by WSU scientists has revealed electricity-consuming bacteria living in a Yellowstone Park hot spring.
For the first time, scientists made a successful in situ collection of bacteria living in hot springs in Yellowstone National Park and using an unconventional source – electricity – for food and energy.
