Electrothrix gigas sp. nov.

Submitted by Schramm, Andreas

Species Electrothrix gigas

[gi'gas] N.L. masc. n. gigas, a giant (nominative in apposition), referring to its very large cell diameter
Nomenclatural type
NCBI Assembly: GCA_022766165.1 Ts
Reference Strain
AU1_5 (TS)
Filamentous bacteria of centimeter length that inhabit the surface of marine and coastal sediment and conduct electrons from sulfide-oxidizing cells to oxygen-reducing cells. Cell diameters >2.5 µm (commonly 2.5-8 µm). Gliding motility. Gram-negative, with distinct ridges running longitudinally along the filament. Can assimilate acetate and propionate; CO2 fixation via the Wood-Ljungdahl pathway. Contains c-type cytochromes and type IV pili (PilA). Polyphosphate and polyglucose storage. Distinguishable by size, 16S rRNA gene sequence and genome.
