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.[1] Like other members of the class Negativicutes, they are gram-negative, despite being Bacillota, which are normally gram-positive.

Etymology

[edit]

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.[1]

Phylogeny

[edit]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[1] and National Center for Biotechnology Information (NCBI).[2]
