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).
菌株DHOC27是从中国广东省鼎湖山生物圈保护区的森林土壤中分离得到的革兰氏阴性、需氧、不运动、浅黄色色素沉着的杆状细菌。它在4-37 °C(最适温度28-33 °C)、pH 4.0-8.5(最适pH 4.5-6.0)和0-1.5(最适0-0.5)%(w/v)NaCl条件下生长。基于16S rRNA基因序列的系统发育分析结果表明,该菌株与吩嗪类伯克霍尔德氏菌LMG 2247、萨氏伯克霍尔德氏菌LMG 24000和苍白玫瑰色伯克霍尔德氏菌DHOK13形成一个分支,与上述菌株的序列相似性分别为98.5%、97.5%和98.1%。DHOC27的DNA G+C含量为62.3 mol%。菌株DHOC27与吩嗪类伯克霍尔德氏菌LMG 2247和萨氏伯克霍尔德氏菌LMG 24000之间的数字DNA-DNA相关性值和平均核苷酸同一性分别为26.9%和24.3%以及82.3%和79.9%。C16 : 0、C17 : 0环丙烷和C19 : 0环丙烷ω8c是主要脂肪酸,检测到的主要呼吸醌是泛醌-8,所有这些都支持DHOC27属于伯克霍尔德氏菌属。基于上述数据,菌株DHOC27代表伯克霍尔德氏菌属的一个新物种,提议命名为Telluris伯克霍尔德氏菌(Paraburkholderia telluris sp. nov.)。模式菌株为DHOC27(=LMG 30263=GDMCC 1.1281)。
