Gram-positive cocci. Non-motile. Non-spore-forming.
Colonies on TSA medium incubated at 30 ºC for 48 hours are light yellow, smooth,
glossy, circular with entire margins, and 1.0-1.2 mm in diameter. Growth occurs at
10-45 ºC, pH 6-11 and with 0-15% (w/v) NaCl.

Isolated from a rhizosphere soil sample of Reaumuria soongorica found in the desert soils of Fukang, Xinjiang, north-west China.
Sensitive to ampicillin, gentamicin, kanamycin, nalidixic acid, neomycin, streptomycin, tetracycline and vancomycin. Resistant to
cephalosporin, chloramphenicol, erythromycin, novobiocin, rifampicin
and roxithromycin.
