endospores. Sporangia are not deformed (admin note).
Colonies on LB medium are white, circular, non-translucent and 2-3 mm in diameter
after incubation at 32 ºC for 48 h. Growth occurs at 15-45 ºC (optimum 30 ºC), at pH
5-10 (optimum pH 6) and with 0-9% (w/v) NaCl (optimum 1%). Facultatively anaerobic.
