Abstract

A novel filamentous bacterial strain, HSS8-18, was isolated from soil from a hot-spring pond in Krabi province, Thailand. The isolate produced single globose bodies and short, finger-like sporangia directly from the substrate mycelium. The cell wall of the isolate contained -diaminopimelic acid, glycine, arabinose and xylose. The characteristic phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, phosphatidylethanolamine and hydroxyl phosphatidylethanolamine. The predominant menaquinones were MK-10(H), MK-9(H) and MK-10(H) and the predominant cellular fatty acids were anteiso-C, iso-C, iso-C, iso-C and anteiso-C. The G+C content of the genomic DNA was 72.0 mol%. 16S rRNA gene sequence analysis indicated that isolate HSS8-18 belonged to the genus and shared the highest 16S rRNA gene sequence similarity with YIM 46034 (98.3 %) and YIM 48875 (98.0 %). However, DNA–DNA hybridization results and some physiological and biochemical properties indicated that strain HSS8-18 could be readily distinguished from its closest phylogenetic relatives. Based on phenotypic and genotypic properties, isolate HSS8-18 is judged to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is strain HSS8-18 ( = BCC 41917  = JCM 17129).
