Scientists from Harvard University identified a bacterium that is unique in its species, called Rhodopseudomonas palustris, which is capable of taking electrons from the environment to survive.
The bacterium obtains its desired electrons using the natural conductivity of minerals located in the soil and sediments, and while remaining on the surface it absorbs the sunlight needed to produce energy.
In nature, the microbe depends on the existence of iron to obtain the electrons needed to generate energy, but in laboratory tests it was observed that it could also obtain electrons from other sources.
