Gram-negative rods, 0.6-0.7 x 1.1-1.4 µm. Weakly motile by one polar flagellum.
Colonies are opalescent, opaque, lackluster, moist, circular and about 1 mm in
diameter after 48-h incubation at 30 ºC on Luria-Bertani agar. Grows at 15-41 ºC
(optimum, 25-30 ºC), at pH 4.0-12.0 (optimum, pH 8.0) and in the presence of 0-6%
NaCl (optimum, 4%). Aerobic.

Isolated from a wheat soil subjected to herbicides for several years.
Sensitive to amikacin, piperacillin, ciprofloxacin, tetracycline, gentamicin. Resistant to roxithromycin, clindamycin, penicillin G,
sulfamethoxazole, amoxicillin, chloramphenicol, bacitracin, erythromycin, vancomycin, ampicillin, azithromycin, rifampicin and
novobiocin.
