Gram-positive, thin, slightly curved, round-ended, rods, 0.7-0.9 x 4.0-7.0 µm, occuring
singly or in pairs. Highly motile. Produce ellipsoidal, or spherical endospores that
appear in subterminal or terminal positions and may swell the sporangia.

Colonies are small (pin-head size, 1 mm in diameter), convex, whitish, glossy, and
have watery texture after 24 h incubation on NA at 30 ºC. Growth occurs at 4-42 ºC
(optimally at 30 ºC), at pH 6-10 (optimally at pH 7) and in 0.5-8% (w/v) NaCl (optimally
in 1-2% NaCl). Growth in anaerobic conditions is weak. Unable to grow on
skimmed-milk agar.
