A Gram-negative, rod-shaped, Brevundimonas-like bacterial strain, DS-18T, was isolated from soil in Dokdo, Korea, and its exact taxonomic position was investigated by using a polyphasic approach. Strain DS-18T grew optimally at pH 6.5–7.0 and 25 °C without NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-18T belonged to the genus Brevundimonas. Strain DS-18T contained Q-10 as the predominant ubiquinone and C18 : 1{omega}7c and C16 : 0 as the major fatty acids. The DNA G+C content was 68.7 mol%. Strain DS-18T exhibited levels of 16S rRNA gene sequence similarity of 96.3–98.7 % to the type strains of Brevundimonas species and Mycoplana bullata. Mean DNA–DNA relatedness values between strain DS-18T and the type strains of phylogenetically related Brevundimonas species and M. bullata were in the range 15–32 %. Strain DS-18T differed from Brevundimonas species and M. bullata in several phenotypic characteristics. On the basis of phenotypic, phylogenetic and genetic data, strain DS-18T represents a novel species of the genus Brevundimonas, for which the name Brevundimonas lenta sp. nov. is proposed. The type strain is DS-18T (=KCTC 12871T =JCM 14602T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain DS-18T is EF363713.

Differential phenotypic characteristics of Brevundimonas lenta sp. nov. and related species are available as supplementary material with the online version of this paper.
