Paraburkholderia telluris sp. nov., isolated from subtropical forest soil.

Strain DHOC27 is a Gram-stain-negative, aerobic, non-motile, light yellow-pigmented and rod-shaped bacterium isolated from the forest soil of Dinghushan Biosphere Reserve, Guangdong Province, PR China. It grew at 4-37 °C (optimal 28-33 °C), pH 4.0-8.5 (optimal 4.5-6.0) and 0-1.5 (optimal 0-0.5) % (w/v) NaCl. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain formed a clade with Paraburkholderia phenazinium LMG 2247, Paraburkholderia. sartisoli LMG 24000 and Paraburkholderia. pallidirosea DHOK13, with a sequence similarity of 98.5, 97.5 and 98.1 % to the above strains, respectively. The DNA G+C content of DHOC27 was 62.3 mol%. The digital DNA-DNA relatedness values and the average nucleotide identities between strain DHOC27 and P. phenazinium LMG 2247 and P. sartisoli LMG 24000 were 26.9 and 24.3 % and 82.3 and 79.9 %, respectively. C16 : 0, C17 : 0 cyclo and C19 : 0 cyclo ω8c were the major fatty acids, and ubiquinone-8 was the major respiratory quinone detected, all of which supported the affiliation of DHOC27 to the genus Paraburkholderia. On the basis of the data presented above, strain DHOC27 represents a novel species of the genus Paraburkholderia and the name Paraburkholderia telluris sp. nov. is proposed. The type strain is DHOC27 (=LMG 30263=GDMCC 1.1281).
