'''''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.<ref name=LPSN /> 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:<br />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.<ref name=LPSN />
==Phylogeny== The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)<ref name=LPSN>{{lpsn3|genus/acidaminococcus|Acidaminococcus}}</ref> and National Center for Biotechnology Information (NCBI).<ref name=NCBI>{{cite web |author=Schoch CL |display-authors=et al. |url=https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?command=show&mode=tree&id=904&lvl=3 |title=Acidaminococcus |accessdate=2025-06-05 |publisher=National Center for Biotechnology Information (NCBI) taxonomy database}}</ref>
