Nomenclatural type
NCBI Assembly: GCA_004284765.1
Reference strain
Nomenclatural status
Validly published under the SeqCode


Filamentous bacteria of centimeter length that inhabit the surface of freshwater sediment and conduct electrons from sulfide-oxidizing cells to oxygen- or nitrate-reducing cells. Gliding motility. Gram-negative, with 40 distinct ridges running longitudinally along the filament. Width of individual cells is 1.7 ± 0.1 µm. Can assimilate acetate but not propionate; CO2 fixation via the Wood-Ljungdahl pathway. Contains c-type cytochromes and type IV pili (PilA). Polyphosphate and polyglucose storage. Distinguishable by morphology and genome.

Submitter comments
Illumina sequencing (2x 300 bp) of DNA from 5 separate samples of a freshwater cable bacterium enrichment culture. A metagenome was assembled from the pooled libraries by IDBA v. 1.1.1, from which the E. aureum genome was extracted. Quality checks were by CheckM.
