A novel actinomycete, designated strain DLS-45T, was isolated from soil from the surface of a rock collected from the peak of Darangshi Oreum (Small Mountain) in Jeju, Republic of Korea. Substrate mycelium was well developed, but aerial mycelium was scant on most of the media tested. Spherical to subspherical spores on the aerial mycelium were in chains that were arranged in hooks and their surfaces were warty. The combination of morphological and chemical features supported the classification of the new isolate in the genus Actinomadura. The neighbour-joining tree based on 16S rRNA gene sequences showed that the strain belonged to the family Thermomonosporaceae and formed a coherent cluster with Actinomadura pelletieri IMSNU 22169T (98.0 % sequence similarity). The other closest relatives were Actinomadura bangladeshensis 3-46-b(3)T (98.2 %) and Actinomadura chokoriensis 3-25-a(11)T (97.9 %). Levels of DNA–DNA relatedness between strain DLS-45T and the type strains of the phylogenetic relatives were less than 17 %. A battery of phenotypic, genotypic and DNA–DNA relatedness data indicated that strain DLS-45T represented a novel species of the genus Actinomadura, for which the name Actinomadura meridiana sp. nov. is proposed. The type strain is strain DLS-45T ( = KCTC 19558T = DSM 45252T).

A novel actinomycete, designated strain OU-40T, was isolated from farm soil collected from the Hyderabad region of Andhra Pradesh, southern India. The strain was found to have morphological and chemotaxonomic characteristics typical of species of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain OU-40T belonged to the genus Streptomyces, and was related most closely to Streptomyces pactum NBRC 13433T (99.0 % sequence similarity), Streptomyces olivaceus NBRC 12805T (99.0 %) and Streptomyces parvulus NBRC 13193T (98.8 %). Strain OU-40T could be distinguished from the type strains of its closest phylogenetic relatives based on levels of DNA–DNA relatedness and comparison of morphological and phenotypic data. It is therefore concluded that strain OU-40T represents a novel species of the genus Streptomyces, for which the name Streptomyces hyderabadensis sp. nov. is proposed. The type strain is OU-40T (=CCTCC AA 209024T =PCM 2692T).

A Gram-positive, aerobic, non-motile, rod-shaped, spore-forming bacterium, designated Gsoil 139T, was isolated from soil from a ginseng field in Pocheon Province, South Korea, and was characterized using a polyphasic approach. Comparative analysis of 16S rRNA gene sequences revealed that strain Gsoil 139T belongs to the family Paenibacillaceae. The greatest sequence similarity was found with respect to the type strains of Paenibacillus hodogayensis (95.6 %) and Paenibacillus koleovorans (93.8 %). The strain showed less than 93.8 % sequence similarity with respect to other species of the genus Paenibacillus. The G+C content of the genomic DNA was 48.1 mol%. In addition, the presence of MK-7 as the major menaquinone and C15 : 0 anteiso as a major fatty acid (27.9 %) justifies its affiliation to the genus Paenibacillus. On the basis of its phenotypic characteristics and phylogenetic distinctiveness, strain Gsoil 139T represents a novel species within the genus Paenibacillus, for which the name Paenibacillus ginsengarvi sp. nov. is proposed.

A Gram-negative, non-motile, rod-shaped bacterial strain, DS-57T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated using a polyphasic approach. It grew optimally at 25 °C and in trypticase soy broth without NaCl and trypticase soy broth with 0.5 % NaCl. Strain DS-57T contained MK-7 as the predominant menaquinone and iso-C15 : 0, C16 : 1 ω7c and/or iso-C15 : 0 2-OH and iso-C17 : 0 3-OH as the major fatty acids. The DNA G+C content was 39.7 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DS-57T was most closely related to the genus Pedobacter of the family Sphingobacteriaceae, clustering coherently with Pedobacter suwonensis, Pedobacter roseus and Pedobacter sandarakinus. Strain DS-57T exhibited 16S rRNA gene sequence similarity values of 99.2, 97.9 and 97.2 % with respect to the type strains of P. suwonensis, P. roseus and P. sandarakinus, respectively, and values less than 95.6 % with respect to the type strains of other Pedobacter species. Strain DS-57T exhibited levels of DNA–DNA relatedness of 45, 17 and 15 % with respect to the type strains of P. suwonensis, P. roseus and P. sandarakinus, respectively. Differential phenotypic properties, together with the phylogenetic distinctiveness and the DNA–DNA relatedness data, were sufficient to allow the classification of strain DS-57T as a species that is separate from recognized Pedobacter species. On the basis of phenotypic properties and phylogenetic distinctiveness, therefore, strain DS-57T represents a novel species of the genus Pedobacter, for which the name Pedobacter terrae sp. nov. is proposed. The type strain is DS-57T (=KCTC 12762T=DSM 17933T).

A novel strain, 219820T, whose metabolites were found to be active against tumour cells, was isolated and characterized. The isolate belonged to the genus Streptomyces and had white to grey aerial mycelium and long chains of smooth spores in the aerial mycelium. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 219820T had highest similarity to members of the genus Streptomyces and was most closely, albeit loosely, associated with Streptomyces crystallinus NBRC 15401T (98.624 % similarity), Streptomyces melanogenes NBRC 12890T (98.565 %) and Streptomyces noboritoensis NBRC 13065T (98.564 %). However, DNA–DNA relatedness and phenotypic data readily distinguished strain 219820T from these phylogenetically related type strains. It is evident from the combination of genotypic and phenotypic data that strain 219820T represents a novel species of the genus Streptomyces, for which the name Streptomyces sanyensis sp. nov. is proposed; the type strain is 219820T ( = CGMCC 4.5626T  = DSM 42014T).
