Abstract

A novel actinomycete, designated strain VN05A0561, was isolated from plant litter collected at Ba Be National Park, Vietnam. The substrate mycelia and spore chains fragmented in a manner similar to nocardioform actinomycetes; the spores had smooth surfaces and were rod-shaped. Strain VN05A0561 had the following chemotaxonomic characteristics: -diaminopimelic acid in the cell-wall peptidoglycan, arabinose and galactose as characteristic sugars, MK-8(H) as the major isoprenoid quinone, phosphatidylcholine as the diagnostic phospholipid and iso-C as the major cellular fatty acid. Strain VN05A0561 shared low levels of 16S rRNA gene sequence similarity (<97 %) with the type strains of recognized species of the genus and could be differentiated from its closest phylogenetic relatives based on phenotypic characteristics. These results suggested that strain VN05A0561 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is VN05A0561 (=VTCC-A-1757=NBRC 105793).
