Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
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 ºC. Produces
fluorescent pigment on King’s B medium.
Aerobic. Very poor growth detected under anaerobic conditions. Grows between 4 and
35 ºC, but not at 37 ºC. Tolerates NaCl up to 5% on nutritive agar.
Isolated from the surface tissue of a rusty root lesion of Korean ginseng (Panax ginseng).
Unknown. It's a possible plant pathogen.
