Two strains of nocardioform actinomycetes, isolated from soil and plant litter in Yamanashi prefecture, Japan, showed substrate mycelium with purple to dark-red colours. 16S rRNA gene sequence analysis indicated that the organisms belonged to the family Actinosynnemataceae and were related closely to Saccharothrix strains (96.7–98.0 % sequence similarity). The isolates contained MK-9(H4) as the predominant menaquinone, meso-diaminopimelic acid, galactose as the diagnostic whole-cell sugar and phosphatidylethanolamine as the predominant polar lipid. Based on a combination of cultural, physiological and chemotaxonomic properties, in addition to the phylogenetic analysis and DNA–DNA hybridization data, we propose a novel species, Saccharothrix violaceirubra sp. nov., for these strains, with the type strain YU 692-1T (=NBRC 102064T =KCTC 19326T).
The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of Saccharothrix violaceirubra YU 692-1T is AB284261.
A scanning electron micrograph of the synnemata of strain YU 692-1T is available with the online version of this paper.
