Gram-positive diphtheroids rods. Non-spore-forming. Non-motile.
Colonies on modified ISP 5 medium, trypticase/soy agar medium and Mueller–Hinton
agar medium are yellow, circular, entire, somewhat convex, opaque and 0.5–1.5 mm
in diameter after 24 h at 28 ºC. Growth at pH 7.2, in 2-3 days. Aerobic. Halotolerant:
grows in 0-25% KCl (optimum 10%).
Isolated from a saline soil sample from the west of China.
Undetermined.

sp. nov., isolated from saline soil in the west of China. IJSEM 54, 779-782.
Most biochemical reactions were determined by API Coryne and API ID 32 E.
Positive results for gelatin hydrolysis, beta-glucuronidase, H2S production, lipase,
nitrate reduction, urease & acid production from glucose.
Can utilize: arabinose, dextrin, glucose, galactose, mannose, mannitol, maltose, starch, ribose, salicin, sucrose & xylose.
Negative results for beta-galactosidase, alpha- and beta-glucosidase, N-acetyl-beta-glucosaminidase, starch hydrolysis, acid
production from: 5-ketogluconate, lactose, maltose, mannitol, ribose, sucrose & xylose. Amygdalin, cellobiose, fructose, and lactose
are not utilized.
