Gram-negative rods, 0.6-1.0 x 1.2-3.4 µm. Motile by one polar flagellum.
Non-spore-forming.
Non-spore-forming.
Colonies grown on Luria-Bertani are round or oval, flat, opaque and beige-coloured
with irregular margins, and are approximately 3-5 mm in diameter after growth for 2
days at 30 ºC. Produce fluorescent pigment on King’s B agar. Pigment is not
produced on King A agar. Grows at temperatures between 4-37 ºC (optimum 30 ºC),
at pH 6.0-10.0 and in the presence of 0-6% (w/v) NaCl. Aerobic.

Isolated from rainbow trouts (Onchorhynchus mykiss) in Turkey, from sand of an intertidal shore on the Galicia coast in Spain and
from water collected at the Woluwe River in Belgium.
