Gram-positive rods. Motile. Produce ellipsoidal, central spores.
Colonies on nutrient agar are peach-coloured, entire, round, flat and 5-8 mm in
diameter. Growth occurs at 10-37 ºC and pH 6-10. Does not grow at 42 ºC or at pH 4
or 11. Tolerates up to 11.6 % NaCl. Resistant to UV radiation. Grows on peptone.
