Amycolatopsis samaneae sp. nov., isolated from roots of Samanea saman (Jacq.) Merr.
A novel actinomycete, designated strain RM287(T), was isolated from surface-sterilized roots of Samanea saman (Jacq.) Merr., collected from Bangkok, Thailand. The status of the novel strain was determined using a polyphasic taxonomic approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism formed a distinct phyletic line within the radiation of the genus Amycolatopsis. The 16S rRNA gene sequence similarity indicated that strain RM287(T) was most closely related to Amycolatopsis mediterranei IMSNU 20056(T) (97.4 %), A. rifamycinica DSM 46095(T) (97.2 %), A. kentuckyensis NRRL B-24129(T) (97.2 %), A. pretoriensis DSM 44654(T) (97 %) and A. australiensis DSM 44671(T) (97 %). The novel organism was found to have chemical properties typical of members of the genus Amycolatopsis such as meso-diaminopimelic acid as the dignostic diamino acid in the cell-wall peptidoglycan and arabinose and galactose as the diagnostic sugars. The major menaquinone was MK-9(H(4)). The major fatty acids were iso-C(16 : 0) iso-C(15 : 0), iso 2-OH-C(16 : 0) and iso-C(17 : 0). The DNA G+C content was 71.7 mol%. Phenotypic data clearly distinguished the novel isolate from its closest relatives. The combined genotypic and phenotypic data indicated that strain RM287(T) represented a novel species of the genus Amycolatopsis. The proposed name for this organism is Amycolatopsis samaneae sp. nov., with the type strain RM287(T) ( = TISTR 1919(T) = BCC 35842(T) = NBRC 106095(T)).
