Gram-positive rods, 0.5-0.9 x 2.0-3.5 µm. Motile. Spores are ellipsoidal,
located subterminally to terminally in swollen sporangia.
located subterminally to terminally in swollen sporangia.
Colonies are cream in colour, with smooth, glossy surfaces and diameters of 0.5-2.0
mm after 24-48 h at 60 ºC. Can grow at temperatures between 37 (weakly) and 70 ºC
(optimum 60 ºC), at pH range 6.0-9.0 (optimum 7.5) and from 0 to less than 5% (w/v)
NaCl. Aerobic.
