Gram-negative rods. Motile by peritrichous flagella.
Colonies are pale yellow in colour, circular, low convex and smooth. Older colonies
spread with irregular edges on LB medium. Grows at 10-45 ºC, pH 5.0-9.0, and can
tolerate up to 10% (w/v) NaCl.
Isolated from the roots of Ammodendron bifolium obtained from Takeermohuer desert, Xinjiang Uygur Autonomous Region, China.
Undetermined.
