Gram-negative rods, 0.67-1.0 x 2.2 μm. Motile by means of one polar flagellum.
After 16 h incubation at 30 ºC on LB agar, colonies are circular, beige in colour, flat,
with regular edges and approximately 3-4 mm in diameter. A fluorescent pigment is
produced on Pseudomonas agar F, but no pyocyanin is produced on Pseudomonas
agar P. Grows at 4-42 ºC (optimum at 30-37 ºC), at pH 5-9 and in the presence of
0-6% (w/v) NaCl (optimum at 2-3%). Strictly aerobic.
