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 novel actinomycete, designated strain 06182M-1T, was isolated from a mangrove soil sample collected from Chiayi County in Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences revealed levels of similarity of 97.0–98.8 % to the type strains of recognized species of the genus Isoptericola. Chemotaxonomic data also supported the placement of strain 06182M-1T within the genus Isoptericola. However, the low levels of DNA–DNA relatedness between the novel strain and the type strains of recognized species of the genus Isoptericola, in combination with differential phenotypic data, demonstrate that strain 06182M-1T represents a novel species of the genus Isoptericola, for which the name Isoptericola chiayiensis sp. nov. is proposed. The type strain is 06182M-1T ( = BCRC 16888T  = KCTC 19740T).

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).

A novel actinomycete, designated strain OU-63T, was isolated from garden soil collected on the campus of Osmania University in Hyderabad, southern India. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Streptomyces, and was related most closely to Streptomyces chartreusis NBRC 12753T (98.6 % similarity). However, the mean level of DNA–DNA relatedness between the two strains was only 25±1.73 %. Based on DNA–DNA relatedness, morphological and phenotypic data, strain OU-63T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces osmaniensis sp. nov. is proposed. The type strain is OU-63T (=CCTCC AA209025T =PCM 2690T).

A coccoid, non-motile actinobacterium, designated strain YIM 70003T, was isolated from a saline, alkaline, desert-soil sample from Egypt. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism formed a distinct phyletic line within the genus Kocuria and was most closely related to Kocuria polaris DSM 14382T (98·6 % sequence similarity) and Kocuria rosea DSM 20447T (98·2 %). Chemotaxonomic data, including the Lys–Ala3 peptidoglycan type, the presence of phosphatidylglycerol and diphosphatidylglycerol as the predominant phospholipids, the presence of MK-8(H2) and MK-9(H2) as the major menaquinones, the predominance of fatty acids ai-C15 : 0 and i-C15 : 0 and the DNA G+C content, also supported the affiliation of the isolate to the genus Kocuria. The low DNA–DNA relatedness with K. polaris DSM 14382T (56·6 %) and K. rosea DSM 20447T (15·5 %) in combination with phenotypic data show that strain YIM 70003T should be classified as a novel species of the genus Kocuria. The name Kocuria aegyptia sp. nov. is proposed, with strain YIM 70003T (=CCTCC AA203006T=CIP 107966T=KCTC 19010T=DSM 17006T) as the type strain.

A Gram-variable, motile, endospore-forming, slightly halophilic bacterial strain, DSW-10T, was isolated from Dokdo, an island located at the edge of the East Sea, Korea, and was characterized taxonomically by using a polyphasic approach. This isolate grew optimally at 37 °C and in the presence of 4–5 % NaCl. Strain DSW-10T had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-7 as the predominant menaquinone, and anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and unidentified phospholipids. The DNA G+C content was 36·7 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DSW-10T is phylogenetically affiliated to the genus Virgibacillus, and exhibited sequence similarity of 95·3–98·7 % to the type strains of Virgibacillus species. DNA–DNA relatedness levels between strain DSW-10T and the type strains of some phylogenetically related Virgibacillus species were in the range 8·4–17·5 %. On the basis of phenotypic properties and phylogenetic and genetic distinctiveness, strain DSW-10T (=KCTC 3933T=DSM 16826T) was classified as the type strain of a novel Virgibacillus species, for which the name Virgibacillus dokdonensis sp. nov. is proposed.

A Gram-negative, aerobic, rod-shaped, motile, oxidase-positive, catalase-negative bacterium, designated strain BL03T, was isolated from landfill soil in Pohang, Republic of Korea. Colonies on Luria–Bertani agar plates were yellow. The strain grew in the presence of 0–3 % (w/v) NaCl, at 15–42 °C and at pH 5.0–9.5. The predominant ubiquinone was Q-10, and the major cellular fatty acids were C17 : 1 ω6c, C15 : 0 2-OH and C18 : 1 ω7c. Polar lipids detected were phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid and an unknown glycolipid. Spermidine was identified as the major polyamine component. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BL03T belongs to the genus Sphingopyxis with high sequence similarity to Sphingopyxis taejonensis JSS54T (97.8 %), Sphingopyxis alaskensis RB2256T (97.4 %) and Sphingopyxis chilensis S37T (96.9 %). Levels of DNA–DNA relatedness between strain BL03T and the above three type strains were only 10.3–40.3 %. The DNA G+C content of strain BL03T was 65.9 mol%. Based on the data presented, strain BL03T is considered to represent a novel species of the genus Sphingopyxis, for which the name Sphingopyxis soli sp. nov. is proposed. The type strain is BL03T (=KCTC 22405T =JCM 15910T).

A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated, non-gliding and rod-shaped bacterial strain, SSK2-2T, was isolated from the place where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK2-2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain SSK2-2T fell within the clade comprising the type strains of species of the genus Maribacter, joining the type strain of Maribacter sedimenticola with which it shared 99.4 % similarity. Sequence similarities to the type strains of other Maribacter species were 94.6–98.2 %. Strain SSK2-2T contained MK-6 as the predominant menaquinone and iso-C17 : 0 3-OH, iso-C15 : 0, iso-C15 : 1 G, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0) as the major fatty acids. The major polar lipids of strain SSK2-2T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain SSK2-2T was 38.2 mol% and mean levels of DNA–DNA relatedness with the type strains of four phylogenetically related species of the genus Maribacter were 11–24 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SSK2-2T is separate from other Maribacter species. On the basis of the data presented, strain SSK2-2T is considered to represent a novel species of the genus Maribacter, for which the name Maribacter confluentis sp. nov. is proposed. The type strain is SSK2-2T ( = KCTC 42604T = CECT 8869T).

Strain KIT 00200-70066-1T was isolated from the sputum of a patient with pulmonary disease. Cells of the strain were Gram-variable, facultatively anaerobic, motile, spore-forming rods and formed colourless to white colonies on tryptic soy agar at 30 °C and pH 7. The pathogenicity of the strain is not known. The strain contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, MK-7 as the predominant menaquinone, anteiso-C15 : 0, iso-C16 : 0 and C16 : 0 as the major fatty acids and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and several unknown lipids in the polar lipid profile. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Paenibacillus, sharing the highest levels of sequence similarity with Paenibacillus nanensis MX2-3T, Paenibacillus agaridevorans DSM 1355T and Paenibacillus alkaliterrae KSL-134T (95.4, 95.2 and 94.8 %, respectively), and that it occupied a distinct position within this genus. Combined phylogenetic and phenotypic data supported the conclusion that strain KIT 00200-70066-1T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus sputi sp. nov. is proposed; the type strain is KIT 00200-70066-1T (=KCTC 13252T =DSM 22699T).
