E. Yabuuchi et al., Burkholderia uboniae sp. nov., L-arabinose-assimilating but different fromBurkholderia thailandensis and Burkholderia vietnamiensis, MICROB IMMU, 44(4), 2000, pp. 307-317
A polar multitrichous Gram-negative motile rod, EY 3383, originally identif
ied as Burkholderia thailandensis, revealed a DNA-DNA reassociation rate of
36.7%, under stringent conditions, with the type strain of B. thailandensi
s, despite the 16S rDNA homology value between two type strains being as hi
gh as 97.9%. The strain was clearly differentiated from the type strain of
B. thailandensis by physiological, biochemical, and nutritional characteris
tics, without significant difference in cellular fatty acid and lipid compo
sition. Based on the results of 16S rDNA sequence analysis, DNA-DNA hybridi
zation and phenotypic characterization, Burkholderia uboniae sp, nov. is he
rein proposed. The type strain is NCTC 13147=EY 3383, isolated on 8 Decembe
r 1989 from surface soil along the roadside in Ubon Ratchathani, Thailand.
Major respiratory quinone is ubiquinone-8(Q(8)). G+C content of DNA is 69.7
1%.
