Gram-positive rods, 1.8 x 5.9 µm. Motile by a single polar flagellum. Produce
subterminal, ellipsoidal endospores.
subterminal, ellipsoidal endospores.
Colonies after 48h of incubation at 37 ºC are creamy, smooth, circular and slightly
irregular, measuring 5-8 mm in diameter. Growth occurs optimally at 37 ºC, pH 7.5
and at 10% NaCl. Aerobic.
