Gram-positive cocci, 0.9 µm in diameter. Non-motile. Non-spore-forming.
Colonies on TSA after 48 hours incubation at 30 ºC are yellow, smooth, glossy
and circular with entire margins. Grows at 5-30 ºC (optimum 20-25 ºC), at pH 7.0-12.0
(optimum pH 8.0), and in the presence of 0-7.5% (w/v) NaCl (optimum 2.5% NaCl).
Aerobic.

Isolated from healthy roots of Glycyrrhiza uralensis F. collected from Xinyuan County, Xinjiang Province, China.
Sensitive to amikacin, chloramphenicol, ciprofloxacin, erythromycin, gentamicin, kanamycin, novobiocin, penicillin G, polymyxin B,
streptomycin, tetracycline and vancomycin. Resistant to netilmicin and tobramycin.
