Acidaminobacter is a genus in the phylum Bacillota (Bacteria).
The name Acidaminobacter derives from Neo-Latin acidum aminum, amino acid, a rod bacter, nominally meaning "a rod", but in effect meaning a bacterium, a staff or rod; resulting in Acidaminobacter, the amino acid rod bacterium.
The genus contains a single species, Acidaminobacter hydrogenoformans. The specific name is based on New Latin hydrogenum (from Greek húdà Âr (á½ÂôÃÂÃÂ), water; and gennaà  (óõýýìÃÂ), to produce) hydrogen (that which produces water, so called because it forms water when exposed to oxygen); Latin formans, forming, giving hydrogen-forming.)
