Gram positive, 0.6-0.9 x 1.2-4.0 μm, straight or slightly curved rods. Motile. Ellipsoidal, paracentral spore, may swell the
sporangium slightly.
sporangium slightly.
Colonies on TSA at 30 ºC are 1-2 mm in diameter, whitish, opaque and flat, with
glossy surfaces and entire margins. Growth temperature from 10 ºC to 35 ºC.
No growth in anaerobic agar. Grow in 5% NaCl, but not in 10% NaCl. NaCl is not
required for growth. Range of pH 6-9, optimum 8. Variable growth at pH 5 and 10.
