Abstract

A Gram-positive, rod-shaped, yellow-pigmented actinomycete, designated strain NAA-13, was isolated from a freshwater spring located in Kaoshiung, southern Taiwan. This strain was characterized using a polyphasic taxonomic approach. The organism had chemotaxonomic and morphological properties consistent with its classification in the genus . The strain contained -diaminopimelic acid as the principal diamino acid of the peptidoglycan, MK-8(H) as the major menaquinone, and iso-C and C as the predominant fatty acids. 16S rRNA gene sequence studies showed that the strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus ; its closest neighbours were DS-51 (94.9 % similarity), KCTC 0074BP (96.5 % similarity) and GW-9 (96.6 % similarity). The DNA GC content of strain NAA-13 was 71.8 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain NAA-13 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is NAA-13 (=LMG 24213=BCRC 16874).
