Gram-negative rods, 0.5-1.0 x 1-3 µm. Motile by peritrichous flagella.

Colonies are about 2.5 mm in diameter after 48 h at 25 ºC and also on yeast peptone
dextrose (YPDA) medium. Colonies are circular, grayish (to yellowish on media
containing sucrose or gelatin), slightly domed, and semitranslucent. Pectinolytic.
Causes maceration of potato tuber slices. Facultatively anaerobic.

Isolated from chicory, leek, celery and hyacinth.

Causes odorous soft rot of chicory (Cichorium intybus L.) and decay of other plants such as leek, celery and hyacinth. The
development of slimy rot in witloof chicories is always associated with the production of a sweet, ripe, banana-like odor.
