Gram-positive bifurcated and elongated cocci, 0.5-1 x 2 µm. Non-spore-forming.
Non-motile.
Non-motile.
Colonies are white to beige, shiny, 1 mm in diameter after 2 days of incubation under
anaerobic or microaerobic conditions on MRS agar. Grows at temperature 10-40 ºC
(optimum 37 ºC; not growing at 45 ºC), pH 5.0-7.0 (not at pH 4.0 or 9.0). Anaerobic;
growth occurs on agar under microaerophilic conditions.
