Gram negative rods, encapsulated, 1.4–1.6 x 0.4–0.5 μm, motile by means of a
single flagellum.
single flagellum.
Colonies on nutrient agar are circular, smooth, non - pigmented, whitish and
transparent, 2–3 mm in diameter, on TSA and MA. Fluorescent pigments and
pyocyanin are not produced on King B and King A medium, respectively. No
hemolysis.
Aerobic. Growth is observed in 0–10% (w/v) NaCl and at temperatures of 7–41 °C; no
growth occurs at 4 or 42 °C; optimal temperature 28 °C. Media: King A & B agar,
Trypticase Soy Agar, Marine agar / broth.
