Gram-positive, ovoid to spherical, 0.5-1.0 x 0.5-1.5 µm, occuring singly, in pairs or
tetrads. No accumulation of poly-beta-hydroxybutyrate granules. Non-spore-forming.
Non-motile.

Non-motile.
Colonies on TSA incubated at 28 °C for 1 week are cream-yellow, with smooth
surfaces in young colonies and rough surfaces in old ones . Grows at 4-45 °C
(optimally at 35 °C), in the presence of 0–7% NaCl (optimally with 0-0.5% NaCl) and
at pH 5–10 (optimally at pH 7.0-8.0). Grows well in complex media, such as TSA and
Luria–Bertani media. Aerobic, poor growth in anaerobic conditions.

Isolated from root of Dysophylla stellata (Lour.) Benth., collected in Yunnan Province, south-west China.
Sensitive to gentamicin, novobiocin, penicillin G, neomycin, bacitracin, vancomycin and tetracycline. Resistant to kanamycin, nalidixic
acid, erythromycin, rifampicin and chloramphenicol.
