Gram-positive rods, 0.3-0.5 x 1.5-2.5 µm, motile by means of peritrichous flagella.
Produce subterminal, spherical or ellipsoidal endospores in swollen sporangia.

Colonies on TSA at 37 ºC are orange and slightly raised. Growth occurs at 15-45 ºC
(optimum 37 ºC), at pH 4.5-10.0 (optimum pH 6.0-7.0), and in the presence of 0-9%
(w/v) NaCl. Aerobic; no anaerobic growth.
