Pseudomonas panacis Park et al. 2005.
Pseudomonas panacis Park et al. 2005.
Gram negative rods, motile by means of one or more flagella. Spores are not formed.
Colonies on nutritive agar are flat, translucent, butyraceous, beige-coloured with
entire margins and usually 2–3 mm in diameter within 2 days at 30 °C. Produces
fluorescent pigment on King’s B medium.
Aerobic. Very poor growth detected under anaerobic conditions. Grows between 4 and
35 °C, but not at 37 °C. Tolerates NaCl up to 5% on nutritive agar.
