Species description is based on a single isolate.
Gram-positive rods, occurring singly or in pairs. Produce oval endospores located
subterminally, swelling the sporangia. Motile.
Colonies on Nutrient agar are cream-white, flat, opaque, and smooth, with circular
margins and are 2-3 mm in diameter. Grows at 15-40 ºC (optimum at 30 ºC), at pH
5-10 (optimum pH 7) and in 0-3% (w/v) NaCl (optimum 0% NaCl). Aerobic.
Isolated from weed rhizosphere soil of the Gobi desert in the Xinjiang Autonomous Region of China.
Undetermined.
