Gram-positive rods, 0.7-1.0 / 2.5-4.28 µm. Non-motile. Non-spore-forming.
Colonies are white, circular to slightly irregular after 2 days of anaerobic incubation at
37 ºC on MRS agar. Can grow at 28-45 ºC (optimally at 30-37 ºC), pH 4.0-11 and in 3%
NaCl media. Grows under microaerophilic and anaerobic conditions.
