Abstract
A polar multitrichous Gram‐negative motile rod, EY 3383, originally identified as Burkholderia thailandensis, revealed a DNA‐DNA reassociation rate of 36.7%, under stringent conditions, with the type strain of B. thailandensis, despite the 16S rDNA homology value between two type strains being as high as 97.9%. The strain was clearly differentiated from the type strain of B. thailandensis by physiological, biochemical, and nutritional characteristics, without significant difference in cellular fatty acid and lipid composition. Based on the results of 16S rDNA sequence analysis, DNA‐DNA hybridization and phenotypic characterization, Burkholderia uboniae sp. nov. is herein proposed. The type strain is NCTC 13147=EY 3383, isolated on 8 December 1989 from surface soil along the roadside in Ubon Ratchathani, Thailand. Major respiratory quinone is ubiquinone‐8(Q8). G+C content of DNA is 69.71%.
