Abstract

The bacteria strain EN12 was isolated from forest soil in the Republic of Korea. The cells were Gram-negative, non-motile and rod-shaped, and the strain was strictly aerobic. Phylogenetic analysis of its 16S rRNA gene sequences showed that strain EN12 belonged to the class of the phylum , and its closest relative is 5G38, with a sequence similarity of 95.5 %. The average DNA sequence similarity from validly described species within the genus was 92.5±1.3 %. Chemotaxonomic data including major ubiquinones (menaquinone-7), polar lipids (phosphatidylethanolamine and sphingolipid) and fatty acids (iso-C, iso-C 3-OH, and C 6/C 7) also supported an affiliation of strain EN12 with the genus . Genotypic and phenotypic differentiation of strain EN12 from six published species was revealed through DNA–DNA relatedness and physiological/biochemical tests. Results of these phenotypic, phylogenetic and chemotaxonomic analyses indicated that strain EN12 is a novel species in the genus , for which we propose the name sp. nov. (=KCTC 42612=LMG 28820).
