A novel, anaerobic filamentous bacterium, strain MO-CFX1T, was isolated from a methanogenic community, which was originally established from subseafloor sediments collected from off the Shimokita Peninsula, Japan. Cells were non-spore-forming, non-motile, Gram-stain-negative and filamentous. The filaments were longer than 10 µm and 130–150 nm in width. Growth of the strain was observed at 10–37 °C (optimum 25–30 °C), at pH 5.5–8.5 (optimum pH 7.0) and in 0–50 g NaCl l−1 (optimum 15 g NaCl l−1). The strain was able to grow with a number of carbohydrates in the presence of yeast extract. The major cellular fatty acids were monounsaturated C18 : 1ω9, C16 : 1ω7 and saturated C18 : 0 and C16 : 0. The intact polar lipids of the strain were dominated by diacylglyceride and sphingolipid core lipid structures with monoglycosidic, mixed phosphomonoglycosidic and fatty-acid-modified monoglycosidic polar head groups. The G+C content of the genomic DNA was 52.4 mol%. Based on the comparative 16S rRNA gene sequence analysis, strain MO-CFX1T was affiliated with the class Anaerolineae within the phylum Chloroflexi and was most closely related to Leptolinea tardivitalis YMTK-2T (sequence identity of 91.0 %). Based on phenotypic and genetic properties of the novel isolate, we propose a novel species representing a new genus Pelolinea submarina gen. nov., sp. nov., for strain MO-CFX1T ( = JCM 17238T, = KCTC 5975T). This is the first formal description, to our knowledge, of an isolate of the phylum Chloroflexi from the deep-sea sedimentary environment.

A novel actinomycete, designated strain NEAU-FHS4T, was isolated from the root of black false hellebore (Veratrum nigrum L.). Strain NEAU-FHS4T formed single spores with smooth surfaces on substrate mycelium. The novel strain contained meso-diaminopimelic as amino acid of the peptidoglycan and xylose and glucose as whole-cell sugars. The predominant menaquinones were MK-10(H6) and MK-10(H8). Mycolic acids were not detected. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol. The predominant cellular fatty acids were iso-C16 : 0, C16 : 0, C18 : 0 and anteiso-C17 : 0. Phenotypic and chemotaxonomic analysis showed that the novel isolate had characteristics typical of members of the genus Plantactinospora . 16S rRNA gene sequence analysis also indicated that strain NEAU-FHS4T belonged to the genus Plantactinospora , with highest sequence similarities to Plantactinospora mayteni YIM 61359T (98.88 %) and Plantactinospora endophytica YIM 68255T (98.85 %). The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the novel strain from the most closely related strains. Based on morphological, chemotaxonomic and phylogenetic data, strain NEAU-FHS4T is considered to represent a novel species of the genus Plantactinospora , for which the name Plantactinospora veratri sp. nov. is proposed. The type strain is NEAU-FHS4T ( = CGMCC 4.7143T = DSM 46718T).

A Gram-stain-negative bacterium, strain 5410S-62T, was isolated from an air sample collected in Suwon, Republic of Korea. It was aerobic, motile, mesophilic and formed rod-shaped cells. Colonies on R2A agar were convex, circular and pale orange with entire margins. Growth occurred at pH 5–9 (optimally at pH 7) and at 10–40 °C (optimally at 28 °C). It did not grow in the presence of 1 % NaCl. Comparative analyses of 16S rRNA gene sequences demonstrated that the novel strain was closely related to members of the genus Noviherbaspirillum . Strain 5410S-62T showed the highest sequence similarity (98.2 %) to Glaciimonas singularis A2-57T. It also showed high 16S rRNA gene sequence similarity (98.1–95.6 %) to members of the genus Noviherbaspirillum (98.1 % to Noviherbaspirillum aurantiacum SUEMI08T, 97.8 % to Noviherbaspirillum soli SUEMI10T and Noviherbaspirillum canariense SUEMI03T, 97.6 % to Noviherbaspirillum psychrotolerans PB1T and 95.6 % to Noviherbaspirillum malthae CC-AFH3T). The strain contained summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), C16 : 0 and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) as major fatty acids, Q-8 as the only ubiquinone and large amounts of phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. Strain 5410S-62T revealed less than 70 % DNA–DNA relatedness with the type strains of closely related species of the genera Noviherbaspirillum and Herbaspirillum and Glaciimonas singularis . Based on the physiological, biochemical and chemotaxonomic data obtained in this study, it is proposed that strain 5410S-62T represents a novel species, Noviherbaspirillum suwonense sp. nov., with 5410S-62T ( = KACC 16657T =  NBRC 108944T) as the type strain.

A novel actinomycete, strain DS3030T, was isolated from a deep sediment sample, collected from the southern Black Sea coast, Turkey, and was examined using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain DS3030T was shown to belong to the genus Saccharomonospora and to be related most closely to Saccharomonospora marina XMU15T (99.6 % similarity). Sequence similarities with other strains of the genus Saccharomonospora were lower than 97.0 %. The organism had chemical and morphological features typical of the genus Saccharomonospora . The cell wall of the novel strain contained meso-diaminopimelic acid, arabinose and galactose as diagnostic sugars. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The predominant menaquinone was MK-9(H4). Major fatty acids were iso-C16 : 0, iso-C16 : 0 2-OH and C16 : 1 cis 9. Phenotypic data clearly distinguished the new isolate from its closest relative, S. marina XMU15T. The combined genotypic and phenotypic data and low DNA–DNA relatedness with its closest related strain reveal that strain DS3030T represents a novel species of the genus, for which the name Saccharomonospora amisosensis sp. nov. is proposed. The type strain is DS3030T ( = DSM 45685T = KCTC 29069T = NRRL B-24885T).

An anaerobic, psychrophilic bacterium, strain MO-SPC2T, was isolated from a methanogenic microbial community in a continuous-flow bioreactor that was established from subseafloor sediments collected from off the Shimokita Peninsula of Japan in the north-western Pacific Ocean. Cells were pleomorphic: spherical, annular, curved rod, helical and coccoid cell morphologies were observed. Motility only occurred in helical cells. Strain MO-SPC2T grew at 0–17 °C (optimally at 9 °C), at pH 6.0–8.0 (optimally at pH 6.8–7.2) and in 20–40 g NaCl l−1 (optimally at 20–30 NaCl l−1). The strain grew chemo-organotrophically with mono-, di- and polysaccharides. The major end products of glucose fermentation were acetate, ethanol, hydrogen and carbon dioxide. The abundant polar lipids of strain MO-SPC2T were phosphatidylglycolipids, phospholipids and glycolipids. The major cellular fatty acids were C14 : 0, C16 : 0 and C16 : 1ω9. Isoprenoid quinones were not detected. The G+C content of the DNA was 32.3 mol%. 16S rRNA gene-based phylogenetic analysis showed that strain MO-SPC2T was affiliated with the genus Sphaerochaeta within the phylum Spirochaetes , and its closest relatives were Sphaerochaeta pleomorpha GrapesT (88.4 % sequence identity), Sphaerochaeta globosa BuddyT (86.7 %) and Sphaerochaeta coccoides SPN1T (85.4 %). Based on phenotypic characteristics and phylogenetic traits, strain MO-SPC2T is considered to represent a novel species of the genus Sphaerochaeta , for which the name Sphaerochaeta multiformis sp. nov. is proposed. The type strain is MO-SPC2T ( = JCM 17281T = DSM 23952T). An emended description of the genus Sphaerochaeta is also proposed.
