Abstract |
A rod-shaped, round and white colony-forming strain AD18T
was isolated from the soil on Halla mountain in Jeju Island,
Republic of Korea. Comparative analysis of 16S rRNA gene
sequence revealed that this strain was closely related to Burkholderia
oklahomensis C6786T (98.8%), Burkholderia thailandensis
KCTC 23190T (98.5%). DNA-DNA relatedness
(14.6%) indicated that the strain AD18T represents a distinct
species that is separate from B. oklahomensis C6786T. The
isolate grew at pH 5.0–9.0 (optimum, pH 7.0), 0–3% (w/v)
NaCl (optimum, 0%), and temperature 10–40°C (optimum
35°C). The sole quinone of the strain was Q-8, and the predominant
fatty acids were C16:0, C17:0 cyclo, and C19:0 cyclo ω8c.
The genomic DNA G + C content of AD18T was 65.6 mol%.
Based on these findings, strain AD18T is proposed to be a novel
species in the genus Burkholderia, for which the name Burkholderia
alba sp. nov. is proposed (= KCCM 43268T = JCM
32403T). The type strain is AD18T. |
