Gram-positive short rods with a mean size of 0.8-1.2 µm; sometimes branching is
observed. In older cultures, cocci predominate. Non-motile. Poly-beta-hydroxybutyrate
granules are not produced.

Colonies show a bright yellow pigmentation. Thiamin.HCl is required, and nicotinic
acid and biotin stimulate growth. The optimal temperature for growth is 27–33.5 °C,
and the optimal pH is 8.6. NaCl tolerance for growth is 0-15%. Aerobic.

Isolated from hypersaline Ekho Lake (Vestfold Hills, East Antarctica).
Undetermined.

Positive results for catalase, citrate utilization (weak), DNase, H2S production, acid production from fructose, maltose, manose,
sucrose, and trehalose.
Can utilize glucose, trehalose, D-fructose, D-mannose, sucrose, and maltose.
Negative results for alginate hydrolysis, gelatinase, indole production, methyl-red test, nitrate reduction, oxidase, starch hydrolysis,
Tween 80 hydrolysis, Voges-Proskauer test, acid production from galactose, lactose, mannitol, and xylose.
