Gram positive / variable, 0.6–1.5 x 1.5–3.5 μm pleomorphic rods. Motile by peritrichous and abundant flagella.
Spores ellipsoidal, central or paracentral, swelling the sporangium.The spore may fill most of the sporangium and may lie
laterally.

Sporulates and germinates at 0 ºC. Facultatively anaerobic. Grow
s in 2% NaCl;
variable growth in 5% NaCl and no growth in  10% NaCl. Range of pH: 6-7.2 to 9.5.
Allantoin or urate are not required.
Isolated  from soil and marshes.
Not determined.
