A Gram-negative bacterium, designated CKTN2T, was isolated from compost. Cells of strain CKTN2T were strictly aerobic rods. The isolate grew at 20-50 °C (optimum 40-45 °C), but not below 15 °C or above 52 °C, and at pH 5.9-8.8 (optimum pH 7.0), but not below pH 5.4 or above pH 9.3. The DNA G+C content was 40.3 mol%. The predominant menaquinone was MK- 7. The major fatty acids were iso-C15:0 (45.2 %), iso-C17:0 3-OH (11.1 %) and C18: 0 (14.5 %). Analysis of the 16S rRNA gene sequence of strain CKTN2T revealed that it is a member of the genus Sphingobacterium and is most closely related to Sphingobacterium alimentarium DSM 22362T (93.2% 16S rRNA gene sequence similarity). Strain CKTN2T could be distinguished from its closest phylogenetic relatives by different phenotypic characteristics. According to the phenotypic and genotypic characteristics, strain CKTN2T represents a novel species of the genus Sphingobacterium, for which the name Sphingobacterium thermophilum sp. nov. is proposed. The type strain is CKTN2T (5JCM 17858T 5KCTC 23708T).
