Cocci, occurring in pairs, tetrads, irregular masses or chains. Gram-stain-positive. Nonmotile. Nonsporeforming. Strictly anaerobic. Metabolize peptones and amino acids; the major metabolic end products are butyric acid, lactic acid and small amounts of propionic and succinic acids. Most species are able to ferment several carbohydrates, but are weakly fermentative. Glucose, fructose, sucrose and lactose are major sugars fermented. Most species do not produce indole. The position 1, position 3, and interpeptide bride of peptidoglycan are glycine or alanine, l-lysine, and d-glutamic acid or d-aspartic acid. Major cellular fatty acid are C18:1, C16:1, C18, and C16 (Ezaki et al., 1983; O'Leary and Wilkinson, 1988). Members of the genus are typically isolated from the human vagina and various purulent secretions.
DNA G+C content (mol%): 30–35.
Type species: Anaerococcus prevotii (Foubert and Douglas 1948) Ezaki, Kawamura, Li, Li, Zhao and Shu 2001b, 1526VP.
