Gram-negative rods. Motile by one or two polar flagella. Non-spore-forming.
Colonies on standard method agar plates are pale yellow to light cream in colour,
opaque, round with an entire margin, raised, smooth, glistening and usually 1-2 mm
in diameter after growth for 2 days at 27 ºC. No diffusible pigments are produced.
Fluorescent pigment is produced on King’s B medium Growth occurs at 4-30 ºC, at
pH 6-8 and in the presence of 0-6% (w/v) NaCl. Levan is produced from sucrose.

Isolated from soft rot lesions of onion (Allium cepa L.) in Japan.
Causes soft rot of onion. Positive for potato soft rot. Not pathogenic to lettuce. Negative for tobacco hypersensitive reaction.
