Gram-negative rods, 0.6-1.0 x 1.2-1.7 µm. Motile by one polar-subpolar flagellum.
Non-spore-forming.
Non-spore-forming.
Colonies are circular convex, beige and usually 1.5-2.0 mm in diameter within 2 days
of growth at 28 ºC. Maximum growth temperature is 35 ºC, optimum 28 ºC, and the pH
range for growth is 5-9, with optimum growth at pH 7. Grows in TSB with 0-6% NaCl,
optimally in 0% NaCl. A diffusible fluorescent pigment is produced on King B
medium. Blue non-fluorescent pigment is not produced. Haemolysis is not produced.
Strictly aerobic.
