A Gram-staining-positive, non-motile, aerobic, non-spore-forming and short rod-shaped bacterial strain, PAMC 26527T, was isolated from biofilm formed in coastal seawater of the Norwegian Sea. Analysis of the 16S rRNA gene sequence of strain PAMC 26527T revealed a clear affiliation with the genus Nocardioides . Based on phylogenetic analysis, strain PAMC 26527T showed the closest phylogenetic relationship with Nocardioides caricicola YC6903T with 16S rRNA gene sequence similarity of 96.3 %. Strain PAMC 26527T grew in the presence of 0–5.0 % sea salts. The optimum temperature and pH for growth were 20 °C and pH 7.5. The major cellular fatty acids of strain PAMC 26527T were iso-C16 : 0, C17 : 1ω8c and C18 : 1ω9c and the major isoprenoid quinone was MK-8(H4). Cell-wall analysis showed that strain PAMC 26527T contained ll-diaminopimelic acid. The genomic DNA G+C content was 69.3 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain PAMC 26527T could be clearly distinguished from recognized members of the genus Nocardioides . Thus, strain PAMC 26527T should be classified as representing a novel species in the genus Nocardioides , for which the name Nocardioides salsibiostraticola sp. nov. is proposed. The type strain is PAMC 26527T ( = KCTC 29158T = JCM 18743T).

Two Gram-stain-positive, rod-shaped and endospore-forming bacteria, designated WM-1T and WM-4, were isolated from a paddy soil and a forest soil, respectively, in South China. Comparative 16S rRNA gene sequence analyses showed that both strains were members of the genus Oceanobacillus and most closely related to Oceanobacillus chironomi LMG 23627T with pairwise sequence similarity of 96.0 %. The isolates contained menaquinone-7 (MK-7) as the respiratory quinone and anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0 as the major fatty acids (>10 %). Polar lipids consisted of a predominance of diphosphatidylglycerol and moderate to minor amounts of phosphatidylglycerol and phosphatidylinositol. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The DNA G+C content was 38.6–39.2 mol%. The 16S rRNA gene sequence of strain WM-1T displayed 99.7 % similarity to that of strain WM-4, and DNA–DNA hybridization between the two strains showed a relatedness value of 91 %. Based on the results of this polyphasic study, strains WM-1T and WM-4 represent a novel species in the genus Oceanobacillus , for which the name Oceanobacillus luteolus sp. nov. is proposed. The type strain is WM-1T ( = KCTC 33119T = CGMCC 1.12406T).

A Gram-staining-positive, aerobic organism, isolated from the Red Sea sponge Spheciospongia vagabunda was investigated to determine its taxonomic position. On the basis of results of 16S rRNA gene sequence analysis strain EG49T was most closely related to Actinokineospora cibodasensis and Actinokineospora baliensis (both 97.3 % similarity) and Actinokineospora diospyrosa and Actinokineospora auranticolor (both 97.0 % similarity). The 16S rRNA gene sequence similarity to all other species of the genus Actinokineospora was <97.0 %. The quinone system of strain EG49T contained the menaquinones MK-9(H4) (47 %), MK-9(H6) (27 %) and MK-9(H2) (15 %) in major amounts. Minor amounts of MK-7(H4) (2 %), MK-9(H0) (1 %), MK-9(H8) (3 %) and MK-10(H4) (3 %) were detected as well in addition to MK-8(H4), MK-8(H6), MK-10(H2) and MK-10(H6) (all <1 %). The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. In the polar lipid profile, diphosphatidylglycerol, phosphatidylethanolamine and hydroxyphosphatidylethanolamine were predominant. Phosphatidylinositol-mannoside, two unidentified phospholipids and two glycoglipids as well as one aminoglycolipid, one aminolipid and one unidentified lipid were found in addition. The fatty acid profile was composed of mainly iso-branched fatty acids: iso-C16 : 0, iso-C14 : 0, iso-C15 : 0 and iso-C16 : 1H. All these findings clearly supported the classification of the strain as representing a member of the genus Actinokineospora . In addition, the results of physiological and biochemical tests also allowed phenotypic differentiation of strain EG49T from the most closely related species of the genus Actinokineospora . Strain EG49T represents a novel species of the genus Actinokineospora , for which we propose the name Actinokineospora spheciospongiae sp. nov., with strain EG49T ( = DSM 45935T = CCM 8480T = LMG 27700T) as the type strain.

The taxonomic position of a novel actinomycete isolated from soil in Fars Province (Iran) was determined using a polyphasic approach. Phenotypic characterization and 16S rRNA gene sequence analysis of the isolate matched those described for members of the genus Streptomyces . On ISP2 medium, strain HM 1154T produced a dark cream, branched substrate mycelium and Retinaculiaperti aerial hyphae that in some images also appeared spiral and that developed into greyish-white spore chains with a smooth surface. The isolate showed optimal growth at 28 °C and pH 6–9 with 0–4 % (w/v) NaCl. Whole-cell hydrolysates contained ll-diaminopimelic acid as diagnostic diamino acid, ribose and glucose. The main phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol, three unknown phospholipids and an unknown aminophospholipid; MK-9(H4) and MK-9(H2) were the predominant menaquinones. The major cellular fatty acids were the branched saturated iso-C16 : 0 and anteiso-C15 : 0. Strain HM 1154T exhibited the highest 16S rRNA gene sequence similarities to Streptomyces coerulescens DSM 40146T (99.4 %), Streptomyces varsoviensis DSM 40346T (99.3 %), Streptomyces youssoufiensis DSM 41920T (99.2 %), Streptomyces abikoensis DSM 40831T (99.2 %), Streptomyces rimosus subsp. rimosus DSM 40260T (99.1 %), Streptomyces luteireticuli DSM 40509T (99.1 %), Streptomyces thioluteus DSM 40027T (99.1 %), Streptomyces blastmyceticus DSM 40029T (99.0 %) and Streptomyces hiroshimensis DSM 40037T (99.0 %). DNA–DNA hybridization studies showed relatedness values of 11.0–35.8 % with the closest related species. Based on these results, strain HM 1154T is considered to represent a novel species within the genus Streptomyces , for which the name Streptomyces zagrosensis sp. nov. is proposed. The type strain is HM 1154T ( = DSM 42018T = UTMC 1154T = CECT 8305T).

An actinomycete strain, designated Sco-B23T, was isolated from a brown-coloured layer of scoria collected near Darangshi Oreum (a small mountain) in Jeju, Republic of Korea. Cells of the organism were Gram-positive, non-endospore-forming, non-motile cocci and grew at 20–35 °C, at pH 5.1–11.1 and with 0–1 % (w/v) NaCl. Colonies were circular, translucent and moderate yellow in colour with entire margins. On the basis of 16S rRNA gene sequence analysis, the isolate belonged to the genus Phycicoccus and formed a monophyletic line between a Phycicoccus bigeumensis – Phycicoccus dokdonensis cluster and a Phycicoccus aerophilus – Phycicoccus ginsenosidimutans cluster. Levels of 16S rRNA gene sequence similarity between strain Sco-B23T and the type strains of Phycicoccus species were: P. bigeumensis (98.8 %), P. dokdonensis (98.7 %), P. aerophilus (97.7 %), P. ginsenosidimutans (97.7 %), P. cremeus (96.9 %) and P. jejuensis (96.5 %). Chemotaxonomic analyses showed that the isolate possessed meso-diaminopimelic acid as the diamino acid of the peptidoglycan, MK-8(H4) as the predominant menaquinone, a polar lipid profile including diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unknown phospholipid and two unknown lipids, predominant fatty acids represented by iso-C15 : 0, C17 : 1 cis9, iso-C16 : 0 and iso-C14 : 0, and DNA G+C content of 69.7 mol%. DNA–DNA relatedness between strain Sco-B23T and the close relatives within the genus Phycicoccus was below 18.1 %. On the basis of phenotypic features and DNA–DNA hybridization data, strain Sco-B23T represents a novel species of the genus Phycicoccus , for which the name Phycicoccus badiiscoriae sp. nov. is proposed. The type strain is Sco-B23T ( = KCTC 19807T  = KACC 15111T  = NBRC 107918T).

A novel filamentous bacterium, strain SCSIO 10219T, was isolated from a sediment sample collected from the South China Sea (113° 3.752′ E 18° 1.722′ N) at a depth of 2105 m. Growth was observed at 25–35 °C (optimum 30 °C) and pH 5.0–8.0 (optimum pH 6.0–7.0). The organism formed yellow–white colonies with radial wrinkles. Aerial mycelium was not produced on any of the growth media tested. Phenotypic characterization and 16S rRNA gene sequence analysis indicated that strain SCSIO 10219T belongs to the family Thermoactinomycetaceae . The strain contained ll-diaminopimelic acid in the cell wall. The predominant menaquinone was MK-7. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and five unknown phospholipids. Major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The DNA G+C content was 46.5 mol%. On the basis of chemotaxonomic properties and phylogenetic analysis based on 16S rRNA gene sequence data, it is proposed that this strain represents a novel species in a new genus, Marininema mesophilum gen. nov., sp. nov., in the family Thermoactinomycetaceae . The type strain of the type species is SCSIO 10219T ( = CCTCC AA 2011006T = DSM 45610T). In addition, we propose that the description of the family Thermoactinomycetaceae should be further emended based on the present study.
