Gram-negative, motile rods.
The colonies are greenish with redish-brown centers on NBTA indicator plates, red
on MacConkey agar plates after 48 h incubation, and light orange on LB, Nutrient, and
BHI agar after 96 h incubation.The phase I colonies are bioluminescent, granulated,
convex, and opaque, and have a sticky consistency. The phase II colonies are fat, kind
of translucent. Maximum temperature for growth in nutrient broth is 35 ºC.
