Gram-positive rods, 0.4-0.8 x 2.1-5.5 µm, occuring single or in long chains. Motile by
peritrchous flagella. Produce ellipsoidal, terminal endospores.
peritrchous flagella. Produce ellipsoidal, terminal endospores.
Colonies grown on solid medium at 55°C are pale white-yellowish in color with an
irregular edge. Colony diameter ranges from 1 to 3 mm. Grows at 30-35 to 70-75 ºC,
(optimal growth at 60 ºC), at pH 5.0-5.5 to 10.5-10.8 (optimum pH 8.0) and at NaCl
concentrations of 0-5% (w/v) with the optimum at 0.2-0.5%; no growth occurs at 6%.
Requires yeast extract (0.05 g/l) for growth. Facultatively anaerobic.
