Abstract:
A Gram-negative, rod-shaped, Brevundimonas-like bacterial strain, DS-18(T), was isolated from soil in Dokdo, Korea, and its exact taxonomic position was investigated by using a polyphasic approach. Strain DS-18(T) grew optimally at pH 6.5-7.0 and 25 degrees C without NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-18(T) belonged to the genus Brevundimonas. Strain DS-18(T) contained Q-10 as the predominant ubiquinone and C(18 : 1)omega7c and C(16 : 0) as the major fatty acids. The DNA G+C content was 68.7 mol%. Strain DS-18(T) 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-18(T) and the type strains of phylogenetically related Brevundimonas species and M. bullata were in the range 15-32 %. Strain DS-18(T) differed from Brevundimonas species and M. bullata in several phenotypic characteristics. On the basis of phenotypic, phylogenetic and genetic data, strain DS-18(T) represents a novel species of the genus Brevundimonas, for which the name Brevundimonas lenta sp. nov. is proposed. The type strain is DS-18(T) (=KCTC 12871(T) =JCM 14602(T)).
