Electrotroph

An electrotroph is a microorganism which can receive electrons necessary for its growth from an electrode (power supply) terminal or other electron donors.

[1] The chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans, that lives in ocean thermal vents, has been shown to exhibit electrotrophic behavior in experiments.

[2] In particular, it switches the electron source for carbon assimilation from diffusible Fe2+ ions to an electrode under the condition that electrical current is the only source of energy and electrons.
