Gram-variable, motile rods, 0.7-0.9 x 2.5-4.5 µm, occurring singly; Gram-positive
reactions are only in cultures of less than 18 h at 30 ºC. Produce paracentral or
subterminal, ellipsoidal endospores wich usually swell the sporangia.

Colonies are 2–5 mm in diameter, have a granular appearance and butyrous texture,
with opaque, cream-colored center and translucent irregular margins after 2 days on
TSA. Aerobic. Growth temperature 20-55 ºC (optimum 40 ºC); pH 5-9 (optimum pH 7).
NaCl, alantoin or urate are not required for growth.
