Gram-positive short rods, 0.5-0.6 x 0.8-1.3 µm. Non-motile. Non-spore-forming.
Colonies are smooth, circular and sulfuryellow in colour on LB-NaCl agar medium.
Alkaliphilic and moderately halophilic. Grows at 10-42 ºC (optimum 37 ºC), at pH
8.0-12.0 (optimum 9.0) and in the presence of 3-15% (w/v) NaCl (optimum 5-10%
(w/v) NaCl). Aerobic.

Positive results for alkaline phosphatase (weak), catalase, oxidase, ONPG (negative in Wang's study), urease, acid production from
fructose, D-fucose, mannitol, rhamnose, sucrose, and L-sorbose.
Can utilize as sole carbon source cellobiose, D-fructose, glucose, myo-inositol, maltose, L-rhamnose, D-sorbitol, sucrose and
trehalose.
Negative results foracid phosphatase, cellulose degradation, esculin hydrolysis, H2S production, indole production, gelatin
liquefaction, alpha-glucosidase, beta-galactosidase, milk coagulation, alpha-mannosidase, nitrate reduction, starch hydrolysis,
trypsin, and Tween 80 hydrolysis, acid production from L-arabinose, D-glucose, D-galactose, lactose, trehalose, and D-xylose.
No utilization of D-galactose, lactose, D-mannitol, D-mannose and raffinose.
