Register list for 3 new Electrothrix species names including Electrothrix gen. nov.

Submitted by Schramm, Andreas

Genus Electrothrix

Etymology: [E.lec'tro.thrix] Gr. neut. n. êlektron, amber (which is the origin of the term electric); Gr. fem. n. thrix, hair; N.L. fem. n. Electrothrix, electric hair
Nomenclatural type: Species Electrothrix communis^Ts
Description: Multicellular filaments, up to several centimeters in length, with 15 to >70 characteristic longitudinal ridges and shared periplasm across cells; electron-conducting; typically spanning the suboxic zone in surface sediments; individual cells are 0.4–8 µm × 2-3 µm in size; polyphosphate inclusions; no sulfur inclusions; gliding motility; mostly marine, including coastal, salt marsh and salt lake inhabiting.
Classification: Bacteria » Desulfobacterota » Desulfobulbia » Desulfobales » Desulfobulbaceae » Electrothrix

Species Electrothrix rattekaaiensis

Etymology: [rat.te.kaai.en'sis] N.L. fem. adj. rattekaaiensis, from Rattekaai, referring to the location of sample collection
Nomenclatural type: NCBI Assembly: GCA_032595675.1 ^Ts
Reference Strain: Rat3
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. Gliding motility. Gram-negative, with 15 distinct ridges running longitudinally along the filament. Width of individual cells is 1.2 µm. Can assimilate acetate and 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.
Classification: Bacteria » Desulfobacterota » Desulfobulbia » Desulfobales » Desulfobulbaceae » Electrothrix » Electrothrix rattekaaiensis
