Burkholderia humi sp. nov., Burkholderia choica sp. nov., Burkholderia telluris sp. nov., Burkholderia terrestris sp. nov. and Burkholderia udeis sp. nov.: Burkholderia glathei-like bacteria from soil and rhizosphere soil

Analysis of partial gyrB gene sequences revealed six taxa in a group of 17 Burkholderia glathei -like isolates which were further examined by (GTG)5-PCR fingerprinting, 16S rRNA gene sequence analysis, DNA–DNA hybridizations, determination of the DNA G+C content, whole-cell fatty acid analysis and an analysis of cell and colony morphology and more than 180 biochemical characteristics. The results demonstrated that one taxon consisting of three human clinical isolates represented Burkholderia zhejiangensis , a recently described methyl-parathion-degrading bacterium isolated from a wastewater-treatment system in China. The remaining taxa represented five novel species isolated from soil or rhizosphere soil samples, and could be distinguished by both genotypic and phenotypic characteristics. We therefore propose to formally classify these bacteria as Burkholderia humi sp. nov. (type strain, LMG 22934T = CCUG 63059T), Burkholderia choica sp. nov. (type strain, LMG 22940T = CCUG 63063T), Burkholderia telluris sp. nov. (type strain, LMG 22936T = CCUG 63060T), Burkholderia udeis sp. nov. (type strain, LMG 27134T = CCUG 63061T) and Burkholderia terrestris sp. nov. (type strain, LMG 22937T = CCUG 63062T).
