Gram-positive irregular rods. Non-motile. Asporogenous.
Colonies are white, opaque, 0.5-1.2 mm in diameter on BHI agar supplemented with
defibrinated sheep blood after 3 days of incubation. Grows under both aerophilic
conditions with 5% CO2 and anaerobic conditions. Optimum growth temperature 35 ºC;
range 20-42 ºC. Grows at pH 5.0-9.0 (optimum pH 6.0).
