Five novel Kitasatospora species from soil: Kitasatospora arboriphila sp. nov., K. gansuensis sp. nov., K. nipponensis sp. nov., K. paranensis sp. nov. and K. terrestris sp. nov.

ABSTRACT

A polyphasic study was carried out to establish the taxonomic positions of six strains isolated from diverse soil samples and provisionally assigned to the genus Kitasatospora. The isolates were found to have chemical and morphological properties consistent with their classification as Kitasatospora strains. Direct 16S rRNA gene sequence data confirmed the taxonomic position of the strains following the generation of phylogenetic trees by using three tree-making algorithms. Five of the isolates were considered to merit species status using complementary genotypic and phenotypic data. These organisms were designated Kitasatospora arboriphila sp. nov. (HKI 0189(T)=2291-120(T)=DSM 44785(T)=NCIMB 13973(T)), Kitasatospora gansuensis sp. nov. (HKI 0314(T)=2050-015(T)=DSM 44786(T)=NCIMB 13974(T)), Kitasatospora nipponensis sp. nov. (HKI 0315(T)=2148-013(T)=DSM 44787(T)=NCIMB 13975(T)), Kitasatospora paranensis sp. nov. (HKI 0190(T)=2292-041(T)=DSM 44788(T)=NCIMB 13976(T)) and Kitasatospora terrestris sp. nov. (HKI 0186(T)=2293-012(T)=DSM 44789(T)=NCIMB 13977(T)). The remaining organism, isolate HKI 0316 (=2122-022=DSM 44790=NCIMB 13978), was considered to be a strain of Kitasatospora kifunensis on the basis of 16S rRNA gene sequence, DNA-DNA relatedness and phenotypic data.
