Old synonym: Pseudomonas urumqiensis Zou et al. 2019.
Species decription is based on a single isolate.
Gram-negative, ovoid cells, 0.8-1.2 x 1.5-2.3 µm. Motile. Non-spore forming.
Colonies on Luria Bertani agar are circular, smooth and bright yellow in colour. Grows
well on LB agar, R2A agar and TSA, but poor growth occurs on Doberener medium.
Growth occurs at 15-42 ºC, pH 4-9 and with NaCl concentrations of 1–6 % (w/v).
Isolated from from rhizosphere soil of Alhagi sparsifolia, collected from Xinjiang, P, China.
Undetermined.
