A novel actinobacterium, designated IPBSL-7T, was isolated from a drilling core 297 m deep obtained from the Iberian Pyrite Belt. The strain was isolated anaerobically using nitrate as the electron acceptor. 16S rRNA gene sequence analysis revealed that it was related to Tessaracoccus flavescens SST-39T (95.7 % similarity), Tessaracoccus bendigoensis Ben 106T (95.7 %), Tessaracoccus lubricantis KSS-17SeT (95.6 %) and Tessaracoccus oleiagri SL014B-20A1T (95.0 %), while its similarity to any other member of the family Propionibacteriaceae was less than 94 %. Cells were non-motile, non-spore-forming, Gram-positive, oval to rod-shaped, and often appeared in pairs or small groups. The strain was facultatively anaerobic, oxidase-negative, catalase-positive and capable of reducing nitrate. Colonies were circular, convex, smooth and colourless. The organism could grow at between 15 and 40 °C, with an optimal growth at 37 °C. The pH range for growth was from pH 6 to 9, with pH 8 being the optimal value. Strain IPBSL-7T had peptidoglycan type A3-γ′, with ll-diaminopimelic acid as the diagnostic diamino-acid and glycine at position 1 of the peptide subunit. The dominant menaquinone was MK-9(H4) (93.8 %). The major cellular fatty acid was anteiso-C15 : 0 (55.0 %). The DNA G+C content was 70.3 mol%. On the basis of phenotypic and phylogenetic results, strain IPBSL-7T can be differentiated from previously described species of the genus Tessaracoccus and, therefore, represents a novel species, for which the name Tessaracoccus lapidicaptus sp. nov. is proposed. The type strain is IPBSL-7T ( = CECT 8385T = DSM 27266T).

Eight facultatively anaerobic rod-shaped bacteria were isolated from raw milk and two other dairy products. Results of phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates are placed in a distinct lineage within the family Propionibacteriaceae with Propioniciclava sinopodophylli and Propioniciclava tarda as the closest relatives (94.6 and 93.5 % similarity, respectively). The cell-wall peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid and was of the A1γ type (meso-DAP-direct). The major cellular fatty acid was anteiso-C15 : 0 and the major polar lipids were diphosphatidylglycerol, phosphatidyglycerol and three unidentified glycolipids. The quinone system contained predominantly menaquinone MK-9(H4). The G+C content of the genomic DNA of strain VG341T was 67.7 mol%. The whole-cell sugar pattern contained ribose, rhamnose, arabinose and galactose. On the basis of phenotypic and genetic data, eight strains (VG341T, WS4684, WS4769, WS 4882, WS4883, WS4901, WS4902 and WS4904) are proposed to be classified as members of a novel species in a new genus of the family Propionibacteriaceae , for which the name Brevilactibacter flavus gen. nov., sp. nov. is proposed. The type strain is VG341T (=WS4900T=DSM 100885T=LMG 29089T) and seven additional strains are WS4684, WS4769, WS4882, WS4883, WS4901, WS4902 and WS4904. Furthermore, we propose the reclassification of P. sinopodophylli as Brevilactibacter sinopodophylli comb. nov.

A novel halophilic, filamentous, actinomycete strain, designated CXB832T, was isolated from a salt pond in Qingdao, China. Optimal growth occurred at 37 °C, pH 7.0–8.0 and 9–12 % (w/v) NaCl. Strain CXB832T formed pale yellow to deep yellow branched substrate mycelium without fragmentation. Abundant white aerial mycelium differentiated into long chains of spores and the spores were rod-shaped with smooth surfaces. Strain CXB832T contained meso-diaminopimelic acid as the diagnostic diamino acid of the cell-wall peptidoglycan, and glucose and xylose as the major whole-cell sugars. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipids, glycolipid and unidentified lipids. MK-10(H8), MK-9(H8), MK-10(H2) and MK-10(H6) were the predominant menaquinones. The major fatty acids were i-C16 : 0 (30.71 %), ai-C17 : 0 (13.31 %) and C16 : 0 (11.28 %). The G+C content of the DNA was 60.1 mol%. Comparative analysis of 16S rRNA gene sequences showed that the novel strain was most closely related to genera within the family Nocardiopsaceae , but formed a separate lineage. The highest sequence similarities were to Nocardiopsis arabia DSM 45083T (95.4 %) and Haloactinospora alba DSM 45015T (94.9 %). On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain CXB832T represents a new genus and novel species in the family Nocardiopsaceae , for which the name Salinactinospora qingdaonensis gen. nov., sp. nov. is proposed. The type strain of the type species is CXB832T ( = DSM 45442T = LMG 25567T).

A novel marine actinomycete, designated strain KJ-029T, was isolated from a marine sediment sample (water depth of 226 m) in Kagoshima, Japan. 16S rRNA gene sequence analysis revealed that the new isolate was most closely related to Micromonospora craniellae LHW 63014T (99.3 % similarity). Phylogenetic analyses of the genus Micromonospora based on 16S rRNA gene sequences showed that strain KJ-029T was clustered with Micromonospora craniellae LHW 63014T and Micromonospora endophytica 202201T. However, digital DNA–DNA hybridization analyses presented low levels of relatedness in the range of 24.8–32.9 % between strain KJ-029T and the above closely related strains. The novel strain contained meso-diaminopimelic acid and 3-OH-diaminopimelic acid, d-glutamic acid, glycine and d-alanine in the cell-wall peptidoglycan. The acyl type of the peptidoglycan was glycolyl and mycolic acids were absent. The major menaquinone was MK-9(H4). The whole-cell sugars consisted of glucose, mannose, xylose and ribose. Phosphatidylethanolamine was detected as the major phospholipid and corresponded to phospholipid type II. The predominant cellular fatty acid was iso-C16 : 0. The DNA G+C content of the genomic DNA was 71.5 mol%. Based on the present polyphasic study, strain KJ-029T represents a novel species of the genus Micromonospora , for which the name Micromonospora pelagivivens sp. nov. is proposed. The type strain is KJ-029T (=NBRC 113519T=TBRC 9233T).

An anaerobic, rod-shaped, hyperthermophilic and acidophilic crenarchaeon, designated strain CBA1501T, was isolated from solfataric soil of the Mayon volcano in the Republic of the Philippines. Phylogenetic analysis showed that strain CBA1501T is affiliated with the genus Vulcanisaeta in the phylum Crenarchaeota . DNA sequence similarities between the 16S rRNA gene of strain CBA1501T and those of Vulcanisaeta distributa IC-017T and Vulcanisaeta souniana IC-059T were 98.5 and 97.4 %, respectively. Strain CBA1501T grew between 75–90 °C, over a pH range of 4.0–6.0 and in the presence of 0–1.0 % (w/v) NaCl, with optimal growth occurring at 85 °C, pH 5.0, and with 0 % (w/v) NaCl. Fumarate, malate, oxidized glutathione, sulfur and thiosulfate were used as final electron acceptors, but FeCl3, nitrate and sulfate were not. The DNA G+C content of strain CBA1501T was 43.1 mol%. On the basis of polyphasic taxonomic analysis, strain CBA1501T represents a novel species of the genus Vulcanisaeta in the phylum Crenarchaeota , for which we propose the name Vulcanisaeta thermophila sp. nov.

A novel psychrophilic strain, SSB001T, was isolated from an alpine swamp meadow soil in Tibet, China, and identified as a representative of a novel phylogenetic subclade in the genus Paenibacillus , with Paenibacillus antarcticus (96.2 %), Paenibacillus macquariensis (96.53 %) and Paenibacillus glacialis (96.2 %) as the most closely related species on the basis of 16S rRNA gene sequence analyses. The strain was distinguished from defined species of the genus Paenibacillus by further study of rpoB gene sequences, phenotypic characterization, cellular fatty acid composition, quinones, polar lipids and meso-diaminopimelic acid in the peptidoglycan. Based upon these results, we propose the strain as a representative of a novel species named Paenibacillus tibetensis sp. nov., with SSB001T ( = ACCC 19728T = DSM 29321T) as the type strain. The DNA G+C content (mol%) of strain SSB001T was 40.18 mol% (HPLC).

A Gram-staining-positive, aerobic, non-motile, irregular coccus, designated strain YIM M13146T, was isolated from a sediment sample collected from the South China Sea at a depth of 2439 m, and its taxonomic position was determined by a polyphasic approach. Optimal growth of the strain was observed at 30 °C (range 5–40 °C), pH 7.0 (pH 6.0–9.0) and 0–1 % NaCl (0–6 %, w/v) on/in tryptic soy agar/broth. Strain YIM M13146T had the major cellular fatty acid anteiso-C15 : 0, the predominant respiratory menaquinone MK-9(H4), peptidoglycan type A3γ (ll-DAP–Gly) containing alanine, glycine, glutamic acid and ll-diaminopimelic acid (ll-DAP) and the polar lipids phosphatidylcholine, diphosphatidylglycerol, one unknown phospholipid and several glycolipids. The G+C content of the DNA was 67.2 mol%. Phenotypic and chemotaxonomic characteristics together with 16S rRNA gene sequence analyses showed that strain YIM M13146T was distinct from its close phylogenetic relatives in the genera Propioniferax and Granulicoccus of the family Propionibacteriaceae . Hence, a new genus and species, Mariniluteicoccus flavus gen. nov., sp. nov., is proposed. The type strain of Mariniluteicoccus flavus is YIM M13146T ( = DSM 25892T = CCTCC AB 2012055T).
