Historical synonym:
Bacillus circulans group 6.
Gram-positive rods, 0.5–0.8 x 3–5 μm. Motile by peritrichous flagella. Produce terminal
/ subterminal, ellipsoidal spores in swollen sporangia.
Colonies are yellowish-gray, translucent, smooth, flat. Grow on nutrient agar & TSA.
Aerobic and anaerobic growth. Grow in 2% NaCl, but not in 5% NaCl media. Growth
temperature 10-50 ºC, optimum 37 ºC.
Can grow at pH 4.5-9.0, optimum 7.
Isolated from soil. Resistance to lysozyme 0.001% is variable.
Undetermined.
