Species description is based on a single isolate.
Gram-negative rods, 0.8-1.0 x 1.8-3.0 μm. Motile by peritrichous flagella.
Colonies on Luria Bertani agar are circular, smooth, creamy white and 1-2 mm in
diameter within 18 h at 30 ºC; swarming is not detected. Growth occurs at 15-42 ºC
(optimally at 30 ºC), in 0-6% NaCl (0% optimally, no growth at 7% NaCl) and at
pH 4.0-9.0 (optimally at pH 7.0-8.0). Facultatively anaerobic.
Isolated from a farmland soil sample in Yixing, China. Nitrogen-fixing bacterium.
Sensitive to streptomycin, chloramphenicol, nalidixic acid, carbenicillin, ofloxacin, nitrofurantoin, erythromycin, sulphamethizole,
kanamycin, tetracycline, neomycin, ampicillin, rifampicin, gentamicin, co-trimoxazole, amikacin, ciprofloxacin, furazolidone, amoxycillin
and norfloxacin. Resistant to bacitracin.
Undetermined.
