Abstract
The bacteria strain EN12T 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 EN12T belonged to the class Sphingobacteriia of the phylum Bacteroidetes, and its closest relative is Pedobacter namyangjuensis 5G38T, with a sequence similarity of 95.5 %. The average DNA sequence similarity from validly described species within the genus Pedobacter was 92.5±1.3 %. Chemotaxonomic data including major ubiquinones (menaquinone-7), polar lipids (phosphatidylethanolamine and sphingolipid) and fatty acids (iso-C15 : 0, iso-C17 : 0 3-OH, and C16 : 1ω6c/C16 : 1ω7c) also supported an affiliation of strain EN12T with the genus Pedobacter. Genotypic and phenotypic differentiation of strain EN12T from six published Pedobacter species was revealed through DNA-DNA relatedness and physiological/biochemical tests. Results of these phenotypic, phylogenetic and chemotaxonomic analyses indicated that strain EN12T is a novel species in the genus Pedobacter, for which we propose the name Pedobacter solisilvae sp. nov. (=KCTC 42612T=LMG 28820T).
