Gram-positive rods, 0.5-1.2 x 3.0-7.0 µm. Motile. Spores are oval, 0.9-1.1 x 1.8-2.0 µm,
located terminally or subterminally, swelling the sporangium.
located terminally or subterminally, swelling the sporangium.
Colonies on agar media, 0.8-1.2 mm in diameter, circular, flat, entire, translucent,
slightly brown, smooth, glistening. In broth smooth viscid pellicles are formed. Grows
between 42 ºC and 67-69 ºC, optimal at 61-63 ºC ; at initial pH 6.5-8.5; in 0.5% NaCI
but not in 2% NaCl. Azide sensitive. Strictly aerobic.
