Gram-negative rods, motile by peritrichous flagella, 0.5-1.0 x 1-3 µm, occuring singly
or in pairs.
Colonies are white, circular with entire margins, convex, and 1.0-2.0 mm in diameter.
Facultatively anaerobic. Optimum growth temperature 26-30 ºC. No growth over 40 ºC.
Isolated from Japanese horseradish (Eutrema wasabi ).
Causes discoloured rhizomes and fibrous rot of Japanese horseradish (Eutrema wasabi), and experimentally, of potato tubers, carrot
and radish roots, midribs of chinese cabbage, tomato and tobacco plants.

Positive results for catalase, nitrates reduction, esculin hydrolysis, acetate utilization, acid production from: glucose, mannitol,
rhamnose, and salicin.
Negative results for casein hydrolysis, oxidase, indole production, arginine dihydrolase, lysine decarboxylase, ornithine
