Gram-positive, motile rods, 0.5-0.8 x 2-12 µm. Produce ellipsoidal, central /
subterminal spore in swollen sporangium.
subterminal spore in swollen sporangium.
Colonies are white, convex, translucent, 0.02-1 mm in diameter 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 15-45 ºC. No growth at 10 or 50 ºC. Can grow in 3 and 5% NaCl.
Grows at pH 7-9 but not at pH 5-6. No growth on TSI agar.
