Gram-negative, straight rods, 0.6-0.8 x 1.8-2.3 µm, occurring singly and in pairs. Motile
by a polar flagellum. Non-spore-forming.
by a polar flagellum. Non-spore-forming.
Colonies are 1.5-2.0 mm in diameter, raised, circular-shaped, and cream-colored
after 48 hours incubation at 25 ºC on Luria Bertani (LB) agar. Non-haemolytic. No
diffusible fluorescent pigment is produced on King B. Growth occurs at 4-30 ºC with
an optimum at 28 ºC, and at pH 4.0-10.0. Tolerant to 0-7% NaCl (w/v) in LB broth.
Strictly aerobic.
