Colonies on solid BYA medium are 4 to 5 mm diameter, have a crenate, low, convex
morphology, and have a “ringed” appearance, with a cream-colored center
surrounded by a ring of light orange, followed by a light blue edge.
Strict aerobe;
obligate microaerophile. Growth occurs on solid media in atmosphere
containing 0.5-
4.0% (vol/vol) oxygen (optimum oxygen concentration, 1 to 2%). No growth under 6%
oxygen or under anoxia.
Optimum temperature is 30 ºC (range 22-37 ºC) ; no growth
at 42 ºC.
