and Kim  2006. Description is based on a single isolate.
Gram-positive, motile rods, 0.8-1.6 x 1.6-2.8 µm, producing oval, central spores.
Colonies are yellow-cream, smooth, convex and slightly irregular. Aerobic. Grow at pH
4.5-9.0  (optimum pH 7.0). Temperature range 15-48 ºC; optimum growth at 35 or 40
ºC. NaCl is not  required for growth; tolerates up to 9% NaCl. Optimum growth occurs
in nutrient broth with 0-3% NaCl added.
Isolated from the rhizosphere of willow roots in Korea.
Not determined.
