Validly published under the SeqCode


Multicellular filaments, up to several centimeters in length, with 15–58 characteristic longitudinal ridges and shared periplasm across cells; electron-conducting; typically spanning the suboxic zone in surface sediments; individual cells are 0.4–3 µm × 1-3 µm in size; no sulfur inclusions; gliding motility; mostly freshwater-inhabiting.
First proposed as Candidatus Electronema on the basis of 16S rRNA and dsrAB sequences amplified from single filaments by Trojan et al. 2016
First genome (from same material as Trojan et al. 2016) published by Kjeldsen et al. 2019
First stable enrichment with genome of an Ca. Electronema strain by Thorup et al. 2021
First closed genome (from same material as Thorup et al. 2021) by Sereika et al. 2023
Proposal for valid publication as Electronema under the SeqCode: Plum-Jensen et al. 2024
