Gram-negative, motile by means of polar multitrichous flagella, nonspore-forming,
straight rods, 2.0-3.5 x 1.3-1.7 μm.
straight rods, 2.0-3.5 x 1.3-1.7 μm.
Colonies are circular, flat, opaque, creamy white to pale yellow with slightly spreading
edges on nutrient agar. Pyocyanin and fluorescent pigments are not produced.
Aerobic, can grow in nutrient broth at 30 and 37 ºC, not at 4 or 42 ºC. Fluorescent
pigment production was tested on King A & King B medium. On CFMM/APs agar get
visible colonies in 3 days at 30 ºC.
