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

Strain DHOC27(T) 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 degrees C (optimal 28-33 degrees 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 Glade with Paraburkholderia phenazinium LMG 2247(T), Paraburkholderia. sartisoli LMG 24000(T) and Paraburkholderia. pallidirosea DHOK13(T), with a sequence similarity of 98.5, 97.5 and 98.1 % to the above strains, respectively. The DNA G+C content of DHOC27(T) was 62.3 mol%. The digital DNA-DNA relatedness values and the average nucleotide identities between strain DHOC27(T) and P. phenazinium LMG 2247(T) and P. sartisoli LMG 24000(T) were 26.9 and 24.3 % and 82.3 and 79.9%, respectively. C-16:0, C-17:0 cyclo and C-19:0 cyclo omega 8c were the major fatty acids, and ubiquinone-8 was the major respiratory quinone detected, all of which supported the affiliation of DHOC27(T) to the genus Paraburkholderia. On the basis of the data presented above, strain DHOC27(T) represents a novel species of the genus Paraburkholderia and the name Paraburkholderia telluris sp. nov. is proposed. The type strain is DHOC27(T) (=LMG 30263(T) =GDMCC 1.1281(T)).
