An electrotroph is a microorganism which can receive electrons necessary for its growth from an electrode (power supply) terminal.
The chemolithoautotrophic bacterium
Acidithiobacillus ferrooxidans, that lives in ocean
thermal vents, has been shown to exhibit electrotrophic behavior in experiments.
[1] 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.
