Burkholderia monticola sp nova, isolated from mountain soil

Abstract

An ivory/yellow, Gram-stain-negative, short-rod-shaped, aerobic bacterial strain, designated JC2948(T), was isolated from a soil sample taken from Gwanak Mountain, Republic of Korea. 16S rRNA gene sequence analysis indicated that strain JC2948(T) belongs to the genus Burkholderia. The test strain showed highest sequence similarities to Burkholderia tropica LMG 22274(T) (97.6%), Burkholderia acidipaludis NBRC 101816(T) (97.5%), Burkholderia tuberum LMG 21444(T) (97.5 %), Burkholderia sprentiae LMG 27175(T) (97.4%), Burkholderia terricola LMG 20594(T) (97.3%) and Burkholderia diazotrophica LMG 26031(T) (97.1 %). Based on average nucleotide identity (ANI) values, the new isolate represents a novel genomic species as it shows less than 90 % ANI values with other closely related species. Also, other phylosiological and biochemical comparisons allowed the phenotypic differentiation of strain JC2948(T) from other members of the genus Burkholderia. Therefore, we suggest that this strain should be classified as the type strain of a novel species of the genus Burkholderia. The name Burkholderia monticola sp. nov. (type strain, JC2948(T)=JCM 19904(T)=KACC 17924(T)) is proposed.
