Acidaminococcus

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.
