sp. nov., isolated from soil of a natural cave.

A Gram-reaction-variable, strictly aerobic, motile, rod-shaped bacterium, designated strain C4-5, was isolated from soil of a natural cave. Cells were oxidase- and catalase-positive and formed endospores in sporangia. The 16S rRNA gene sequence comparison showed that the organism formed a distinct clade within the genus and was most closely related to CKOBP-6 ( = KCTC 13623) (96.85 % 16S rRNA gene sequence similarity) followed by CAU 1005 ( = KCTC 33036) (94.82 %). The following chemotaxonomic features of strain C4-5 are typical for the genus : -diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, MK-7 as the predominant menaquinone, the major fatty acids of anteiso-C, iso-C and C and the DNA G+C content of 54.8 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and four unidentified aminophospholipids. The phenotypic and phylogenetic data presented support that strain C4-5 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is C4-5 ( = KCTC 33652 = DSM 100100).
