Gram-negative rods, 0.6-0.8 x 1.5-6.0 µm, motile by peritrichous flagella. Produce
subterminal, ellipsoidal endospores in swollen sporangia.

Colonies are white on complex medium at pH 10. Aerobic. Growth occurs at pH 7 to
10 (optimum pH 8-10) and at 15-40 ºC. Grow in nutrient broth with 2-11% NaCl
added. Allantoin and urate are not required for growth. NaCl requirement is variable.

Isolated from garden soil in Hokkaido, Japan.
