Gram-positive rods with rounded ends, 0.5-0.7 x 1.6 to 2.8 µm. Motile. Produce
ellipsoidal endospores in terminal position; not swelling the sporangium (admin note).
ellipsoidal endospores in terminal position; not swelling the sporangium (admin note).
After 48 h growth on 2216E medium at 30 ºC, colonies are circular, cream white,
smooth and 1.5±0.15 mm in diameter. Growth occurs at 10-30 ºC (optimum 25 ºC), at
pH 6.0-11.0 (optimum 8.0) and in the presence of 0-7% (w/v) NaCl (optimum 0% (w/v)
NaCl). Aerobic.
