Gram negative rods. Motile by means of a single polar flagellum. Poly-beta-
hydroxybutyrate is not accumulated.
Grows on MacConkey agar, Salmonella Shigella (SS agar and Cetrimide and in BHI)
with 3 % (w/v) NaCl. Variable growth in BHI with 5 % (w/v) NaCl. No growth in BHI with
7, 9 and 10 % (w/v) NaCl. Grow
s at 4 ºC and 30 ºC, with weak growth at 37 ºC and no
growth at 41 ºC. Does not grow anaerobically on CSA.
No beta-haemolysis. Produces
fluorescent pigment (pyoverdin) on King B medium,
Isolated from French natural mineral waters.
Unknown.
