Abstract

A Gram-positive-staining, filamentous bacterial strain that developed cylindrical sporangia containing four oval- to rod-shaped spores at the ends of short sporangiophores on branched aerial mycelium was isolated from tropical rainforest soil near a hot spring. The cell-wall peptidoglycan contained -diaminopimelic acid, glutamic acid and alanine as cell-wall amino acids; the whole-cell hydrolysate contained rhamnose, madurose, glucose, galactose and 3--methylmannose as whole-cell sugars. The predominant menaquinone was MK-9(H). Mycolic acids were not detected. The diagnostic phospholipid was phosphatidylethanolamine. The predominant cellular fatty acids were iso-C and 10-methylated C. The G+C content of the DNA was 71.1 mol%. The phenotypic and chemotaxonomic analyses showed that the isolate had characteristics typical of members of the genus . Furthermore, 16S rRNA gene sequence analysis also indicated that this strain belongs to the genus , but as a putative novel species. Following phenotypic, chemotaxonomic and genotypic studies, the isolate is proposed to be a representative of a novel species, to be named sp. nov. The type strain is BCC 21825 (=NBRC 104271). An emended description of the genus is also presented.
