A Gram-stain-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterium, designated W-WS1(T), was isolated from wood falls collected around Wando, an island located in the South Sea, Republic of Korea. Strain W-WS1(T) grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 0-3.0% (w/v) NaCl. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain W-WS1(T) belonged to the genus Pedobacter , clustering coherently with the type strains of Pedobacter daechungensis , Pedobacter lentus , Pedobacter terricola , Pedobacter arcticus and Pedobacter glucosidilyticus , showing 94.3-96.3% sequence similarity. Strain W-WS1(T) exhibited 16S rRNA gene sequence similarity values of 91.2-94.0% to the type strains of other species of the genus Pedobacter. Strain W-WS1(T) contained MK-7 as the predominant menaquinone and iso-C(15 : 0), iso-C(17 : 0) 3-OH and summed feature 3 (C(16 : 1)ω7c and/or C(16 : 1)ω6c) as the major fatty acids. The major polar lipids detected in strain W-WS1(T) were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain W-WS1(T) was 37.7 mol%. The differential phenotypic properties, together with its phylogenetic distinctiveness, revealed that strain W-WS1(T) is separated from recognized species of the genus Pedobacter . On the basis of the data presented, strain W-WS1(T) is considered to represent a novel species of the genus Pedobacter , for which the name Pedobacter silvilitoris sp. nov. is proposed. The type strain is W-WS1(T) ( = KCTC 42174(T) = CECT 8669(T)).
