Old synonym:
Burkholderia diazotrophica Sheu et al. 2013.
Gram-negative rods, 0.8-1.0 x 1.0-2.0 μm. Motile. Non-sporeforming. Accumulate poly-
beta-hydroxybutyrate.
Colonies are yellow-pigmented, circular, smooth and convex with entire edges,
1.0-1.3 mm in diameter on YEM agar after 48 h incubation at 25 ºC. Grows at 15-40 ºC
(optimum, 30-37 ºC), at pH 4.0-8.0 (optimum, pH 6.0-7.0) and with 0-1% (w/v) NaCl
(optimum, 0%).
Isolated from nitrogen-fixing nodules on the roots of Mimosa spp. Nodulation and nitrogen fixation of Mimosa pudica are present.
Sensitive to chloramphenicol, kanamycin, streptomycin, nalidixic acid, tetracycline, sulfamethoxazole + trimethoprim, gentamicin,
penicillin G, novobiocin, ampicillin and resistant to rifampicin.
Undetermined.
