The generic position of two isolates from soils inside a gold mine cave in
Kongju, Korea, was determined by 16S rDNA sequencing and chemotaxonomic
characteristics. Phylogenetic analysis indicated that both of the isolates
formed a clade with Lentzea albidocapillata and members of the genus
Saccharothrix of the family Pseudonocardiaceae. The chemical composition of
the isolates and of Lentzea albidocapillata was consistent with that of the
genus Saccharothrix, which is characterized by a type III cell wall (the
meso-isomer of diaminopimelic acid, and galactose and rhamnose as
characteristic whole-cell sugars), MK-9(H(4)) as the major menaquinone, and
a phospholipid type PII pattern (phosphatidylethanolamine as a diagnostic
phospholipid). The combination of morphological features, chemotaxonomic
characters and phylogenetic data supported the proposal that Lentzea
albidocapillata, the only and type strain of the genus Lentzea, should be
transferred to the genus Saccharothrix. On the basis of physiological
properties, cellular fatty acid composition and DNA--DNA hybridization
data, two new species within the genus Saccharothrix are proposed:
Saccharothrix violacea sp. nov., type strain LM 036(T) (=IMSNU 50388(T)),
and Saccharothrix albidocapillata comb. nov., type strain DSM 44073(T)
(=IMSNU 21253(T)). |
