Bacillus pabuli (ex Schieblich 1923) Nakamura 1984.
Gram-positive, motile (peritrichous flagella) rods, 0.5–1.0 x 2–4 μm. Produce ellipsoidal
spore in swollen sporangium.
Colonies are grayish-white, translucent, smooth, flat, 1-2 mm in diameter after 3 days
at 30 ºC. Grow on nutrient agar. Aerobic and anaerobic growth. Growth temperature
5-10 to 35-40 ºC, optimum 28-30 ºC. No growth at 50 ºC. Grow in 2% and 3% NaCl,
variable at 5% NaCl. Grow at pH 5.6.
Habitat: soil and fodder. Resistance to lysozyme 0.001% is negative.
Undetermined.
