Electronema halotolerans sp. nov. and Electrothrix laxa sp. nov.
Submitted by Schramm, Andreas
Species Electrothrix laxa
- Etymology
- [la'xa] L. fem. adj. laxa, large, referring to its relatively large cell diameter compared to other cable bacteria species
- Nomenclatural type
- NCBI Assembly: GCA_942492895.1 Ts
- Reference Strain
- MAR-scMAG (TS)
- Description
-
Filamentous bacteria of centimeter length that inhabit the surface of marine and coastal sediment and conduct electrons from sulfide-oxidizing cells to oxygen- or nitrate-reducing cells. Gliding motility. Gram-negative, with distinct ridges running longitudinally along the filament. Cell diameters 1-6 µm. 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 morphology and genome.
- Classification
- Bacteria » Desulfobacterota » Desulfobulbia » Desulfobales » Desulfobulbaceae » Electrothrix » Electrothrix laxa

Species Electronema halotolerans
- Etymology
- [ha.lo.to'le.rans] Gr. masc. n. hals, salt, brine; L. pres. part. tolerans, tolerating; N.L. part. adj. halotolerans, salt tolerant. Due to its presence in, and genomic adaptations to, brackish/saltwater.
- Nomenclatural type
- NCBI Assembly: GCA_942493095.1 Ts
- Reference Strain
- BRK-cMAG (TS)
- Description
-
Filamentous bacteria of centimeter length that inhabit the surface of brackish/intertidal sediment and conduct electrons from sulfide-oxidizing cells to oxygen-reducing cells. Gram-negative, width of individual cells is 1-2 µm. Can assimilate acetate but not propionate; CO2 fixation via the Wood-Ljungdahl pathway. Contains c-type cytochromes, type IV pili (PilA) and Na+antiporters. Polyphosphate and polyglucose storage. Distinguishable by morphology and genome.
