Liu et al.  2008.
Gram-negative non-motile, nonspore-forming, round-ended, aerobic rods,
approximately 0.6–0.8 x 0.7–1.1 μm.
On Luria Bertani agar plates, produces dry, yellow, circular, convex, translucent, hard,
wrinkled colonies and approximately 1.0–2.5 mm in diameter within 2 days at 30 ºC.
Fluorescent pigments are not produced on King’s medium B. The temperature, pH and
NaCl ranges for growth are 5–42 ºC (optimum, 30–37 ºC), pH 5.0–9.0 (optimum, pH
7.0–8.0) and 0–2% NaCl (optimum, 0–1 %). Good growth occurs on nutrient agar,
MacConkey agar and Simmons’ citrate agar.
Isolated from a desert soil sample in China.
Resistant to vancomycin.
Unknown.
