Gram-negative motile rods, 1.0-1.5 μm in length, about 0.5 μm diameter.
Forms mucoid colonies with regular margins when grown on TSA and produces
brown-orange difusible pigment. Strictly aerobic, optimum growth temperature 30 ºC.
Media: Trypticase Soy Agar ± 5% sheep blood, Nutrient agar, King's B medium.
Isolated from Brassica napus & Arabidopsis thaliana rhizoplane.

Oxidase-positive, arginine dihydrolase-positive, produces levan, not pectinolytic.
Reduction of nitrate to nitrite is variable.
Hydrolyses gelatin, but not aesculin.
Acid is produced from sucrose and sorbitol but not from erythritol & mannitol.
