  abstract = {{D}eep-sea hydrothermal vents are extreme and complex ecosystems based on a trophic chain. {W}e are still unsure of the identities of the first colonizers of these environments and their metabolism, but they are thought to be (hyper)thermophilic autotrophs. {H}ere we investigate whether the electric potential observed across hydrothermal chimneys could serve as an energy source for these first colonizers. {E}xperiments were performed in a two-chamber microbial electrochemical system inoculated with deep-sea hydrothermal chimney samples, with a cathode as sole electron donor, {CO}2 as sole carbon source, and nitrate, sulfate, or oxygen as electron acceptors. {A}fter a few days of culturing, all three experiments showed growth of electrotrophic biofilms consuming the electrons (directly or indirectly) and producing organic compounds including acetate, glycerol, and pyruvate. {W}ithin the biofilms, the only known autotroph species retrieved were members of {A}rchaeoglobales. {V}arious heterotrophic phyla also grew through trophic interactions, with {T}hermococcales growing in all three experiments as well as other bacterial groups specific to each electron acceptor. {T}his electrotrophic metabolism as energy source driving initial microbial colonization of conductive hydrothermal chimneys is discussed.},
