Gram-negative rods. Motile. Non-spore-forming.
Colonies are rounds, convex, mucoid, beige colored, with regular margins (3-5 mm)
on TSA-YE after incubation for 48 h at 28 ºC. No fluorescent pigments or pyocyanin
production. Grows at temperature range of 4-30 ºC (optimum 28 ºC),at pH 5-9
(optimum pH 6.5) and 0-5% NaCl (optimum 0% NaCl).
