RANK: Species

TAXONOMY: Terrabacteria group -> Firmicutes -> Negativicutes -> Selenomonadales -> Acidaminococcaceae -> Acidaminococcus -> Acidaminococcus fermentans


Acidaminococcus is a genus in the phylum Firmicutes (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 Firmicutes, which are normally gram-positive. Identified as constituent of vaginal microbiome. [PMID:23282177]

This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
