Gram-negative, slightly curved rods, 0.6-0.7 x 1.6-2.3 µm, motile by means of a single
polar flagellum.

Colonies are yellow on YDCP medium and King medium B. A diffusible fluorescent
pigment is produced on King medium B. No poly-beta-hydroxybutyrate accumulation.
Aerobic, growth factors are not required. Growth temperature 28 ºC, no growth at 4, 37
or 42 ºC.
