Gram-positive rods. Motile. Endospores are formed within 24 h of incubation at 60 ºC
on NA containing 5 mg MnSO4 /l ; they are ellipsoidal and sometimes cylindrical, lie
subterminally and/or terminally and do not swell the sporangia.

Colonies after 24 h incubation at 60 ºC on NA are circular in shape with smooth edges,
glossy surfaces and diameters of approximately 5 mm. Grows between 37 and 70 ºC
(at 48 h), with optimum at 60 ºC. Grows at pH 5.0 and 9.0 with optimum growth at pH
6.5-7.0. Tolerates up to 0.5% NaCl.Strictly aerobic.
