Gram negative, 1.3–1.9 / 0.5–0.7 µm; motile with a single polar flagellum, rods.
On solid medium: circular, convex, translucent , yellow colonies and 0.5–2.5 mm in
diameter / 48 h. Produce a water-insoluble yellow pigment and a fluorescent pigment.
Strictly aerobic, optimum growth temperature 28 ºC. No growth at 4 or 41 ºC.
