Abstract
The generic position of two isolates from soils inside a gold mine cave in Kongju, Korea, was determined by 16S rDNA sequencing and chemotaxonomic cha racteristics. Phylogenetic analysis indicated that both of the isolates for med a clade with Lentzea albidocapillata and members of the genus Saccharot hrix of the family Pseudonocardiaceae. The chemical composition of the isol ates and of Lentzea albidocapillata was consistent with that of the genus S accharothrix, which is characterized by a type III cell wall (the meso-isom er of diaminopimelic acid, and galactose and rhamnose as characteristic who le-cell sugars), MK-9(H-4) as the major menaquinone, and a phospholipid typ e PII pattern (phosphatidylethanolamine as a diagnostic phospholipid). The combination of morphological features, chemotaxonomic characters and phylog enetic data supported the proposal that Lentzea albidocapillata, the only a nd type strain of the genus Lentzea, should be transferred to the genus Sac charothrix. On the basis of physiological properties, cellular fatty acid c omposition and DNA-DNA hybridization data, two new species within the genus Saccharothrix are proposed: Saccharothrix violacea sp. nov., type strain L M 036(T) (=IMSNU 50388(T)), and Saccharothrix albidocapillata comb. nov., t ype strain DSM 44073(T)(=IMSNU 21253(T)).
