Pedobacter silvilitoris sp. nov., isolated from wood falls

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_16:1ω7c and/or C_16:1ω6c) 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 WWS1^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).
