A novel Gram-stain-positive actinobacterium, designated HR08-44T, was isolated from a sea-sediment sample collected from the foreshore of Rishiri Island, Japan, and its taxonomic position was investigated by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain HR08-44T was closely related to the members of the genus Janibacter , with pairwise sequence similarities of 97.3–98.8 %. Strain HR08-44T had peptidoglycan type A1γ, with meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinone was MK-8(H4) and the major fatty acids were iso-C16 : 0, C17 : 1ω8c, C17 : 0 and C18 : 1ω9c. These data supported the affiliation of the novel strain to the genus Janibacter . Meanwhile, the results of DNA–DNA hybridization and physiological and biochemical tests indicated that strain HR08-44T can be distinguished from recognized species of the genus Janibacter . Therefore, strain HR08-44T represents a novel species of the genus Janibacter , for which the name Janibacter cremeus sp. nov. is proposed; the type strain is HR08-44T ( = NBRC 107693T = DSM 26154T).

A Gram-stain-negative, aerobic, rod-shaped and motile bacterium, designated THG-DD7T, was isolated from tomato plant rhizosphere soil. Strain THG-DD7T grew optimally at 25–30 °C, at pH 7.0–7.5 and in the presence of 0.5 % (w/v) NaCl. According to the results of 16S rRNA gene sequence comparisons, strain THG-DD7T was most closely related to Rhodanobacter umsongensis GR24-2T (98.2 %), Rhodanobacter panaciterrae LnR5-47T (98.0 %), Rhodanobacter soli DCY45T (97.9 %), Rhodanobacter terrae GP18-1T (97.9 %) and Dyella ginsengisoli Gsoil 3046T (97.7 %). The DNA G+C content was 65.2 mol%. In DNA–DNA hybridization, the DNA relatedness levels between strain THG-DD7T and its closest phylogenetically neighbours were below 40.0 %. The predominant isoprenoid quinone was ubiquinone Q-8. The major polar lipids were diphosphatidylglycerol, phosphtidylethanolamine, phosphatidyl-N-methylethanolamine and phosphatidylglycerol. The major fatty acids were iso-C15 : 0, iso-C16 : 0, iso-C17 : 0, anteiso-C15 : 0 and iso-C17 : 1ω9c and/or C16 : 0 10-methyl (summed feature 9). These data supported the affiliation of strain THG-DD7T to the genus Rhodanobacter . The results of physiological and biochemical tests enabled strain THG-DD7T to be differentiated genotypically and phenotypically from the species of the genus Rhodanobacter with validly published names. Therefore, the novel isolate represents a novel species, for which the name Rhodanobacter koreensis sp. nov. is proposed. The type strain is THG-DD7T ( = KACC 17650T = JCM 19614T).

A Gram-positive, non-spore-forming bacterium (GW-12028T) of unknown origin showing filamentous growth and producing spherical sporangia was studied for its taxonomic allocation. The 16S rRNA gene sequence analysis and subsequent similarity studies showed that strain GW-12028T belongs to the genus Streptosporangium , and is most closely related to Streptosporangium pseudovulgare DSM 43181T (99.9 %) and Streptosporangium nondiastaticum DSM 43848T (99.6 %) and more distantly related to Streptosporangium fragile IFO 14311T (98.4 %) and other species of the genus Streptosporangium (95.8 to 98 %). Chemotaxonomic analyses showed that the peptidoglycan diamino acid was meso-diaminopimelic acid. Whole-cell hydrolysates contained madurose as the diagnostic sugar and exhibited a quinone system that contained predominantly menaquinones with nine isoprenoic units in the side chain [MK-9, MK-9(H2), MK-9(H4)]. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phoshatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannosides, four unidentified glycolipids, a phospholipid and an aminolipid. The polyamine pattern contained the major compounds spermine and spermidine. The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C15 : 0. These chemotaxonomic traits are common to other species of the genus Streptosporangium . DNA–DNA hybridizations and physiological and biochemical tests in comparison with the type strains of the most closely related species, S. nondiastaticum and S. pseudovulgare , allowed genotypic and phenotypic differentiation of strain GW-12028T. This strain represents a novel species, for which we propose the name Streptosporangium sandarakinum sp. nov., with the type strain GW-12028T ( = LMG 27062T  = DSM 45763T).

A Gram-stain-positive, novel actinobacterium, designated strain JL-6T, was isolated from the litter of a bamboo (Sasa borealis) forest in Damyang, Korea. Strain JL-6T had white‐grey, smooth, cylindrical spores that were borne in straight, long spore-chains. The novel strain grew aerobically at 15–28 °C (optimum, 28 °C), pH 4.0–8.0 (optimum, pH 5.5) and with 0–1.5 % (w/v) NaCl. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glutamic acid, alanine and glycine. The predominant menaquinones were MK-9(H6) and MK-9(H8). Whole-cell hydrolysates mainly contained glucose and ribose. Phosphatidylinositol and phosphatidylcholine were the diagnostic phospholipids. The G+C content of the genomic DNA was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JL-6T belonged to the genus Streptomyces with sequence similarities ranging from 97.3 % to 98.3 %. However, DNA–DNA hybridization between JL-6T and the closest related strain, Streptomyces turgidiscabies , ATCC 700248T and other closely related species in the genus Streptomyces showed <50 % relatedness. Based on these observations, strain JL-6T is proposed to represent a novel species of the genus Streptomyces , for which the name Streptomyces graminilatus sp. nov. is proposed. The type strain is JL-6T ( = KACC 16470T = NBRC 108882T).

A Gram-positive, aerobic, coccus-shaped, non-endospore-forming bacterium (Gsoil 633T) was isolated from soil from a ginseng field in Pocheon province in South Korea. The novel isolate was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarities, strain Gsoil 633T was shown to belong to the family Propionibacteriaceae. The closest phylogenetic relative was Microlunatus phosphovorus DSM 19555T, with 96.1 % sequence similarity; the sequence similarity to other members of the family was less than 95.4 %. The isolate was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 69.8 mol%. The morphological and chemotaxonomic properties of the isolate were consistent with those of M. phosphovorus, but the results of physiological and biochemical tests allowed the phenotypic differentiation of strain Gsoil 633T from this species. Therefore, strain Gsoil 633T represents a novel species, for which the name Microlunatus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 633T (=KCTC 13940T=DSM 17942T).
