Gram-positive rods, 0.5 x 4-5 µm, non-motile. Borne subterminally, ellipsoidal
endospores in swollen sporangia.
endospores in swollen sporangia.
Colonies are brownish, circular, opaque, flat, 3-7 mm. in diameter on peptone - yeast
extract - succinate (PYES) agar. Alkalitolerant. Facultatively anaerobic.
Growth is observed at pH 6 - 9.5; temperature range 18-42 ºC (optimum 30-37 ºC).
NaCl is not required for growth, 2% NaCl tolerance. Allantoin or urate are not required.
