Gram-positive, motile (peritrichous flagella) rods, 1-1.2 x 3-8 µm. Produce ellipsoidal,
central / subterminal spore in swollen sporangium.
central / subterminal spore in swollen sporangium.
Colonies are white, convex, 1-3 mm in diameter after incubation at 37 ºC 2 days on C
agar (5 g peptone Difco, 1 g yeast extract Difco, 4 g K2HPO4, 1 g MgSO4 * 7H2O, 0.2 g
KCl,0.02 g FeSO4 * 7H2O and 1000 ml distilled water and adjusted to pH 7.0). Aerobic
and anaerobic growth. Growth temperature 20-45 ºC, optimum 37 ºC. No growth at 15
or 50 ºC. Can grow in 3%, but not in 5% NaCl. Grow at pH 6.5-9 (optimum pH 7.5),
but not at pH 5-6.
