subterminally endospores in swollen sporangia.
Colonies on Degryse 162 medium containing 5% NaCl are orange. Growth factors
are required for growth. Aerobic. Grow at pH 6.5-8.5 (optimum pH 8.0). Temperature
range 20-40 ºC; no growth at 15 or 45 ºC. Halophilic, NaCl is required for growth.
Optimum growth occurs in nutrient broth with 4-6% NaCl added.
