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.
