Abstract

A novel bacterial strain, designated PMB02, was isolated from a leaf of the tree . Colonies grown on TYG agar plates were circular, pink-pigmented and slow-growing, being 0.2–1.5 mm in diameter after 3 days growth. The cells of strain PMB02 were Gram-negative, aerobic, motile rods that possessed oxidase and catalase activities and grew at 20–30 °C, pH 6–8 and in media containing less than 1 % NaCl. The major respiratory quinone was identified as Q-10. A phylogenetic analysis based on 16S rRNA gene sequence comparisons indicated that strain PMB02 was related to members of the genus . A comparative 16S rRNA gene sequence-based phylogenetic analysis placed the strain in a clade with the species and , with which it showed sequence similarities of 97.7 and 97.4 %, respectively. The values for DNA–DNA hybridization between strain PMB02 and CCM 7218 and GR3 were less than 32 %. On the basis of the phenotypic characterization, the phylogenetic analysis and the DNA–DNA relatedness data, strain PMB02 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is PMB02 (=KCTC 12901=JCM 14648).
