Non-spore-forming.
Colonies are cream in colour, with sharp edges and small irregular cores, 0.1-2.2
mm in diameter after 2 days of incubation under anaerobic conditions on TPY agar.
Anaerobic; no growth on agar under microaerophilic conditions. Growth temperature
10-40 ºC, optimum 37 ºC; no growth at 5 ºC. Grows at pH 5.0, weak growth at pH 4.5.
