betavasculorum (Thomson et al. 1984) Hauben et al. 1999.

Gram-negative rods, motile (peritrichous flagella), 0.5-1.0 x 1-3 µm. Occur 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 sugar beet, sunflower, artichoke and potato.

Causes root vascular necroses of sugar beet.

Positive results for catalase, casein hydrolysis, nitrates reduction, esculin hydrolysis, acetate utilization, acid production from:
glucose, mannitol, rhamnose, sucrose and salicin.

Negative results for oxidase, indole production, arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase, urea hydrolysis
and acid production from adonitol.
