Gram positive rods, 0.3-0.4 x 2.0-3.0 µm. Motile by peritrichous flagella. Produce
ellipsoidal spores located subterminally in the swollen sporangium.
ellipsoidal spores located subterminally in the swollen sporangium.
Colonies are circular to slightly irregular and cream-coloured. Grows at 20-40 ºC
(optimum 37 ºC), at pH range 8-10 (optimum at around pH 9-10). Can grow in 12%
(w/v) NaCl, but not in 15% NaCl.
