Gram-negative or Gram-variable, ellipsoidal- to rod-shaped cells depending on age,
2.0 x 2.5-3.5 µm, occuring singly, in pairs, or in clumps. Motile by lophotrichous
flagella that tend to bind together to form thick, whip-like structures. Cysts are not
formed.

Colonies are 2–6 mm in diameter (after several days incubation at 30 ºC),
translucent, low convex, butyrous, and smooth. Produce a brown-black pigment in the
presence of benzoate. A fluorescent pigment is not produced. Optimum temperature
for growth is around 30 ºC; minimum 14 ºC. Variable growth at 9 ºC. Grows
aerobically and microaerobically.
