The novel strain GMKU 370T was isolated from roots of a Thai jasmine rice plant (Oryza sativa L. ‘KDML 105’) collected from Pathum Thani Rice Research Center, Pathum Thani province, Thailand. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain GMKU 370T formed a distinct clade within the genus Actinoallomurus. Strain GMKU 370T contained meso-diaminopimelic acid and lysine in the cell-wall peptidoglycan and galactose and madurose as whole-cell sugars. No mycolic acids were detected. The predominant menaquinones were MK-9(H6) and MK-9(H8). The polar phospholipids consisted of phosphatidylglycerol and phosphatidylinositol. These chemical properties reveal that strain GMKU 370T belongs to the genus Actinoallomurus. Strain GMKU 370T is distinct from the phylogenetically closely related type strains Actinoallomurus iriomotensis NBRC 103685T and Actinoallomurus coprocola NBRC 103688T (99.20 % 16S rRNA gene sequence similarity to both) in terms of differences in phenotypic characteristics and DNA–DNA relatedness (51 and 17 %, respectively). It is proposed that strain GMKU 370T represents a novel species of the genus Actinoallomurus, for which the name Actinoallomurus oryzae sp. nov. is proposed. The type strain is GMKU 370T ( = BCC 31373T  = NBRC 105246T).

Two novel actinomycete strains, designated KB2-4T and KB9-2, were isolated from soil samples. Both isolates formed finger-shaped sporangia on short sporangiophores that emerged directly from substrate hyphae. The cell-wall peptidoglycan contained glutamic acid, glycine, alanine and meso-diaminopimelic acid; the whole-cell sugars were galactose, glucose, mannose, rhamnose, ribose and xylose. The diagnostic phospholipid was phosphatidylethanolamine. The predominant menaquinones were MK-9(H8) and MK-9(H6). Mycolic acids were not detected. The predominant cellular fatty acids (>20 %) were iso-C16 : 0 and anteiso-C17 : 0. For both strains, the G+C content of the genomic DNA was about 72 mol%. The morphological and chemotaxonomic characteristics of the two strains were typical of members of the genus Dactylosporangium. Phylogenetic analysis using 16S rRNA gene sequences also indicated that these strains should be classified in the genus Dactylosporangium and showed that the closest relative was Dactylosporangium salmoneum NRRL B-16294T (99.1 % 16S rRNA gene sequence similarity). DNA–DNA relatedness and some physiological and biochemical properties indicated that the isolates could be readily distinguished from their closest phylogenetic relatives. On the basis of these phenotypic and genotypic data, the isolates represent a novel species, for which the name Dactylosporangium tropicum sp. nov. is proposed. The type strain is strain KB2-4T ( = BCC 34760T  = JCM 15673T).
