Species description is based on a single isolate.
Gram-positive cells showing a rod-coccus cycle. Non-motile. Non-spore-forming.
Colonies on nutrient agar are round, convex, glossy, with entire margins and have a
yellow, non-fluorescent pigment. Good growth at 1-25 ºC (facultative psychrophile). No
growth occurs at pH 5 or 11. Can tolerate 1-3% (w/v) NaCl. Aerobic.
