terminally, ellipsoidal endospores in swollen sporangia.
Colonies are creamy-white on alkaline meat extract-peptone medium, 1-2 mm in
diameter (2 days at 45 ºC). Obligately alkaliphilic. Grow at pH 9-10 ( 9.7 optimum), in
0-10%% NaCl (optimum 1-2% NaCl). Growth temperature 10-47 ºC (optimum 30-35
ºC. Allantoin, urate or NaCl are not required for growth.

Isolated from soil and feces (of old horses), Denmark and Germany; one strain was contaminant on an agar plate in Great Britain.
