Gram-positive rods, 3.0-5.0 x 0.9-1.2 µm. Motile. Produce ellipsoidal endospores that
lie terminally and swell the sporangia.
lie terminally and swell the sporangia.
Colonies after 24 h incubation at 60 ºC on Nutrient Agar are opaque and white in colour,
circular, with smooth edges and glossy surfaces, and diameters of approximately 0.5
mm. Grows at 40-65 ºC, with an optimum at 55 ºC. Grows between pH 6 and 9; no
growth at pH 5. Tolerates up to 2% NaCl. Facultatively anaerobic.
