Definition: A genus of nonmotile, strictly anaerobic bacteria (family Peptococcaceae) containing gram-positive cocci, 1.8–3.0 mcm in diameter, which divide in three perpendicular planes, producing regular packets of eight or more cells. The metabolism of these chemoorganotrophic organisms is fermentative. Saprophytic and facultatively parasitic species occur. The type species is Sarcina ventriculi.
