Acidaminococcus is a genus in the phylum Bacillota (Bacteria), whose members are anaerobic diplococci that can use amino acids as the sole energy source for growth. Like other members of the class Negativicutes, they are gram-negative, despite being Bacillota, which are normally gram-positive.

Etymology

The name Acidaminococcus derives from:
Neo-Latin noun acidum (from Latin adjective acidus, sour), an acid; Neo-Latin adjective aminus, amino; Neo-Latin masculine gender noun coccus (from Greek masculine gender noun kokkos (κόκκος), grain, seed), coccus-shaped; Neo-Latin masculine gender noun Acidaminococcus, the amino acid coccus.

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).
