A catalase-positive, rod-shaped, non-proteolytic, non-motile, anaerobic bacterial strain, designated B086562T, was isolated from a blood culture of an 84-year-old male patient in Israel. According to 16S rRNA gene sequence phylogeny, this strain has no known close relatives among recognized bacteria but should be placed within the family Lachnospiraceae . The most closely related recognized bacteria were from the ‘ Clostridium clostridioforme group’: C. clostridioforme (92.4 %) and Clostridium bolteae (92.3 %). The isolate produced butyrate, lactate, acetate and succinate as major metabolic end products. The major fatty acids were C16 : 0 and C18 : 1 cis 9 DMA and the DNA G+C content was 46.0 mol%. On the basis of the phenotypic properties and phylogenetic distinctiveness, the blood isolate represents a novel species of a new genus in the family Lachnospiraceae , for which the name Eisenbergiella tayi gen. nov., sp. nov. is proposed. The type strain of Eisenbergiella tayi is B086562T ( = LMG 27400T = DSM 26961T = ATCC BAA-2558T).

Four novel strains isolated from the cloacal contents of snow finches (Montifringilla taczanowskii) were characterized as aerobic, Gram-stain-negative, slightly motile, and rod-shaped. Analysis of the 16S rRNA gene sequence revealed that strain CF-458T had the highest similarities of 96.9 and 96.4 % with Limnobaculum parvum HYN0051T and Pragia fontium DSM 5563T, while strain CF-1111T shared the highest similarities of 96.4 and 96.1 % with Pantoea rodasii LMG 26273T and Pectobacterium punjabense SS95T. Phylogenomic analysis showed the four isolates were separated into group Ⅰ (CF-458T and CF-917) and group Ⅱ (CF-1111T and CF-509), and clustered independently in the vicinity of the genera Limnobaculum and Pragia . Summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c, 23.9 and 17.2 %, respectively), C16 : 0 (21.8 and 22.1 %, respectively) and C14 : 0 (10.6 and 17.7 %, respectively) were the common major fatty acids, and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c, 12.3 %) was also a major fatty acid for strain CF-458T while cyclo-C17 : 0 (13.1%) was for strain CF-1111T. Both had Q-8 as the sole quinone and contained phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol as the major polar lipids. The DNA G+C content of strains CF-458T and CF-1111T was 45.7 and 45.4 mol%, respectively. Based on taxonomic position in the phylogenomic tree and phenotypic properties, two novel species of a new genus within the family Budviciaceae are thus proposed, with the name Jinshanibacter gen. nov., zhutongyuii sp. nov. (type strain CF-458T=CGMCC 1.16483T=GDMCC 1.1586T=JCM 33489T) and Jinshanibacter xujianqingii sp. nov. (type strain CF-1111T=CGMCC 1.16786T=GDMCC 1.1587T=JCM 33490T), respectively.

A novel red-pigmented halophilic archaeon, strain EB27T, was isolated from Aran-Bidgol salt lake, a hypersaline playa in Iran. Cells of strain EB27T were non-motile and pleomorphic (rods to triangular or disc-shaped). Strain EB27T required at least 2.5 M NaCl and 0.1 M MgCl2 for growth. Optimal growth was achieved at 4 M NaCl and 0.5 M MgCl2. The optimum pH and temperature for growth were pH 7.5 and 40 °C; it was able to grow at pH 6.0–8.0 and 25–50 °C. 16S rRNA gene sequence analysis showed that strain EB27T is a member of the family Halobacteriaceae ; however, levels of 16S rRNA gene sequence similarity were as low as 90.0, 89.3 and 89.1 % to the most closely related haloarchaeal taxa, namely Halalkalicoccus tibetensis DS12T, Halosimplex carlsbadense 2-9-1T and Halorhabdus utahensis AX-2T, respectively. The DNA G+C content of strain EB27T was 61 mol%. Strain EB27T contained phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester, common phospholipids found in haloarchaea, together with two minor phospholipids. The only quinone present was MK-8(II-H2). Physiological, biochemical and phylogenetic differences between strain EB27T and recognized genera of extremely halophilic archaea suggest that this strain represents a novel species in a new genus within the family Halobacteriaceae , for which the name Halovenus aranensis gen. nov., sp. nov. is proposed. The type strain of Halovenus aranensis, the type species of the new genus, is strain EB27T ( = IBRC-M 10015T = CGMCC 1.11001T).

A Gram-stain-negative, strictly aerobic and heterotrophic bacterial strain, designed strain D1T, was isolated from a recirculating mariculture system in Tianjin, China. Its taxonomic position was determined using a polyphasic approach. Cells of strain D1T were non-flagellated short rods, 0.3–0.5 µm wide and 0.5–1.0 µm long. Growth was observed at 15–30 °C (optimum, 25 °C), at pH 5.5–9.0 (optimum, pH 6.5–7.0) and in the presence of 1–8 % (w/v) NaCl (optimum, 2–3 %). Cells contained carotenoid pigments but not flexirubin-type pigments. Strain D1T contained MK-6 as the sole menaquinone and phosphatidylethanolamine (PE) as the sole phospholipid and four unidentified lipids. The major cellular fatty acids (>10 %) were iso-C15 : 0 (23.2 %), iso-C17 : 0 3-OH (15.2 %), C16 : 1ω7c/C16 : 1ω6c (14.3 %), iso-C15 : 0 3-OH (13.5 %) and iso-C15 : 1 G (10.8 %). 16S rRNA gene sequence analyses indicated that strain D1T belonged to the family Flavobacteriaceae and showed closest phylogenetic relationship to the genus Lutibacter , with highest sequence similarity to Lutibacter aestuarii MA-My1T (92.2 %). The DNA G+C content of strain D1T was 35.9 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain D1T was considered to represent a novel species in a new genus of the family Flavobacteriaceae , for which the name Wenyingzhuangia marina gen. nov., sp. nov. is proposed. The type strain of the type species is D1T ( = CGMCC 1.12162T = JCM 18494T).

A novel obligately anaerobic, non-spore-forming, rod-shaped mesophilic, halophilic, Gram-stain-negative bacterium, was isolated from sediments of Guaymas Basin. The strain, designated Ra1766G1T, grew at 20–40 °C (optimum, 30–35 °C) and at pH 6.0–8.0 (optimum, pH 6.5–7.5). It required 0.5–7.5 % NaCl (optimum, 2–3 %) for growth. Sulfate, thiosulfate, elemental sulfur, sulfite, fumarate, nitrate and nitrite were not used as terminal electron acceptors. Strain Ra1766G1T used cellobiose, glucose, mannose, maltose, arabinose, raffinose, galactose, ribose, sucrose, pyruvate and xylose as electron donors. The main fermentation product from glucose metabolism was acetate. The predominant cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, anteiso DMA-C15 : 0 and C16 : 0. The main polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, iso-DMA-C15 : 0 glycolipids and phospholipids. The G+C content of the genomic DNA was 31.2 mol%. The closest phylogenetic relatives of strain Ra1766G1T were Natranaerovirga pectinivora AP3T (92.4 % 16S rRNA gene sequence similarity), Natranaerovirga hydrolytica APP2T(90.2 %) and Defluviitalea saccharophila 6LT2T (88.9 %). On the basis of phylogenetic inference and phenotypic properties, strain Ra1766G1T represents a novel species of a new genus for which the name Vallitalea guaymasensis is proposed. The type strain of the type species is Ra1766G1T ( = DSM 24848T = JCM17997T).

During our previous studies we reclassified Clostridium coccoides and a number of misclassified ruminococci into a novel genus Blautia within the family Lachnospiraceae . However, the Rules of the Bacteriological Code currently require that the types of all species and subspecies with new names (including new combinations) be deposited in two different collections in two different countries. The type strain of Ruminococcus obeum was, at that period in time, only deposited in the American Type Culture Collection (ATCC) and a second independent deposit, as required by the Code, was not available. Consequently, the transfer of this species to the genus Blautia could not be made, because the resulting species name would not conform to the Rules governing the valid publication of species names and deposit of type material (Rules 27 and 30) and consequently would not be considered to be validly published. This resulted in a nomenclatural and taxonomic anomaly with R. obeum being phylogenetically placed among members of the genus Blautia with 16S rRNA gene sequence similarities of between 91.8 and 96.6 %. In order to rectify this unsatisfactory situation, through our discussions with the ATCC, the deposit of strain R. obeum ATCC 29174T to the DSMZ as strain number DSM 25238T was completed. Hence, the transfer of R. obeum to the genus Blautia as Blautia obeum comb. nov. is now proposed. The type strain is ATCC 29174T ( = DSM 25238T = KCTC 15206T).

A Gram-stain-positive, non-motile rod, designated strain SGM3-12T, was isolated from paddy soil in Suwon, Republic of Korea. 16S rRNA gene sequence analysis revealed that the strain represented a novel member of the family Microbacteriaceae . The nearest phylogenetic neighbour was Leifsonia kribbensis MSL-13T (97.4 % 16S rRNA gene sequence similarity). Strain SGM3-12T and Leifsonia kribbensis MSL-13T formed a distinct cluster within the family Microbacteriaceae . Strain SGM3-12T contained MK-12(H2) and MK-11(H2) as the predominant menaquinones with moderate amounts of MK-12 and MK-11; anteiso-C15 : 0 and iso-C16 : 0 as the major cellular fatty acids (>10 % of total); and diphosphatidylglycerol, phosphatidylglycerol and unidentified glycolipids as the polar lipids. The peptidoglycan type of the isolate was B1δ with l-Lys as the diagnostic cell-wall diamino acid. On the basis of these results, strain SGM3-12T represents a novel species within a new genus, for which the name Lysinimonas soli gen. nov., sp. nov. is proposed (the type strain of the type species is SGM3-12T = KACC 13362T = NBRC 107106T). It is also proposed that Leifsonia kribbensis be transferred to this genus as Lysinimonas kribbensis comb. nov. (the type strain is MSL-13T = DSM 19272T = JCM 16015T = KACC 21108T = KCTC 19267T).

A novel filamentous bacterium, designated strain JIR-001T, was isolated from hemipelagic sediment in deep seawater. This strain was non-motile, Gram-positive, aerobic, heterotrophic and thermophilic; colonies were of infinite form and ivory coloured with wrinkles between the centre and the edge of the colony on ISP2 medium. The isolate grew aerobically at 55–73 °C with the formation of aerial mycelia; spores were produced singly along the aerial mycelium. These morphological features show some similarities to those of the type strains of some species belonging to the family Thermoactinomycetaceae . Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain JIR-001T belongs to the family Thermoactinomycetaceae within the class Bacilli . Similarity levels between the 16S rRNA gene sequence of strain JIR-001T and those of the type strains of Thermoactinomycetaceae species were 85.5–93.5 %; highest sequence similarity was with Melghirimyces algeriensis NariEXT. In the DNA–DNA hybridization assays between strain JIR-001T and its phylogenetic neighbours the mean hybridization levels with Melghirimyces algeriensis NariEXT, Planifilum fimeticola H0165T, Planifilum fulgidum 500275T and Planifilum yunnanense LA5T were 5.3–7.5, 2.3–4.7, 2.1–4.8 and 2.5–4.9 %, respectively. The DNA G+C content of strain JIR-001T was 55.1 mol%. The major fatty acids were iso-C15 : 0, iso-C17 : 0, iso-C16 : 0 and C16 : 0. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, glucolipid, phosphatidylserine, an amino-group containing phospholipid, an unknown phospholipid and two unknown lipids. The predominant menaquinone was MK-7 and the cell-wall peptidoglycan contained meso-diaminopimelic acid, glutamic acid and alanine. On the basis of phenotypic characteristics and 16S rRNA gene sequence comparisons, strain JIR-001T is considered to represent a novel species in a new genus of the family Thermoactinomycetaceae , for which the name Polycladomyces abyssicola gen. nov., sp. nov. is proposed. The type strain of Polycladomyces abyssicola is JIR-001T ( = JCM 18147T = CECT 8074T).

A bacterial strain designated M1MS02T was isolated from a surface-sterilized nodule of Medicago sativa in Zamora (Spain). The 16S rRNA gene sequence of this strain showed 96.5 and 96.2 % similarity, respectively, with respect to Gluconacetobacter liquefaciens IFO 12388T and Granulibacter bethesdensis CGDNIH1T from the family Acetobacteraceae . The novel isolate was a Gram-stain-negative, non-sporulating, aerobic coccoid to rod-shaped bacterium that was motile by a subpolar flagellum. The major fatty acid was C18 : 1ω7c and the major ubiquinone was Q-10. The lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, two aminophospholipids, three aminolipids, four glycolipids, two phospholipids and one lipid. Strain M1MS02T was catalase-positive and oxidase- and urease-negative. Acetate and lactate were not oxidized. Acetic acid was produced from ethanol in culture media supplemented with 2 % CaCO3. Ammonium sulphate was assimilated in glucose medium. The strain produced dihydroxyacetone from glycerol. Phylogenetic and phenotypic analyses commonly used to differentiate genera within the family Acetobacteraceae showed that strain M1MS02T should be classified as representing a novel species of a new genus within this family, for which the name Endobacter medicaginis gen. nov., sp. nov. is proposed. The type strain of the type species is M1MS02T ( = LMG 26838T = CECT 8088T). To our knowledge, this is the first report of a member of the Acetobacteraceae occurring as a legume nodule endophyte.
