The taxonomy of strain CCUG 55240T, a Gram-staining-positive, aerobic, endospore-forming bacterium that was isolated from a paper mill, was investigated using a polyphasic approach. In phylogenetic analysis based on 16S rRNA gene sequences, the novel strain was grouped with established members of the genus Paenibacillus and appeared most closely related to the type strains of Paenibacillus chinjuensis (93.7 % sequence similarity), P. elgii (93.7 %) and P. chitinolyticus (93.6 %). The levels of 16S rRNA gene sequence similarity with other species of the genus Paenibacillus , including the type species of the genus, Paenibacillus polymyxa , were all <93.5 %. The fatty acid profile of strain CCUG 55240T, which showed a predominance of iso- and anteiso-branched fatty acids, supported the allocation of the strain to the genus Paenibacillus . Unusually high amounts of some iso-branched fatty acids, especially iso-C15 : 0 and iso-C16 : 0, allowed differentiation of strain CCUG 55240T from the most closely related species of the genus Paenibacillus . The diagnostic diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid. The predominant menaquinone was MK-7. The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, an unknown glycolipid, an unknown aminophosphoglycolipid and an unknown phospholipid. Spermidine was the major polyamine. The results of some physiological and biochemical tests also allowed the phenotypic differentiation of strain CCUG 55240T from the most closely related recognized species. On the basis of the phylogenetic, phenotypic and molecular evidence, strain CCUG 55240T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus chartarius sp. nov. is proposed. The type strain of the novel species is CCUG 55240T ( = CCM 7759T).

Two lactic acid-producing, Gram-stain-positive rods were isolated from a microbial mat actively growing in the littoral zone of an Antarctic lake (Forlidas Pond) in the Pensacola mountains and studied using a polyphasic taxonomic approach. The isolates were examined by phylogenetic analysis of the 16S rRNA gene, multilocus sequence analysis of pheS, rpoA and atpA, and biochemical and genotypic characteristics. One strain, designated LMG 26641, belonged to Carnobacterium alterfunditum and the other strain, designated LMG 26642T, could be assigned to a novel species, with Carnobacterium funditum DSM 5970T as its closest phylogenetic neighbour (99.2 % 16S rRNA gene sequence similarity). Carnobacterium iners sp. nov. could be distinguished biochemically from other members of the genus Carnobacterium by the lack of acid production from carbohydrates. DNA–DNA relatedness confirmed that strain LMG 26642T represented a novel species, for which we propose the name Carnobacterium iners sp. nov. (type strain is LMG 26642T  = CCUG 62000T).

Four unknown strains belonging to the genus Arthrobacter were isolated from plateau wildlife on the Qinghai–Tibet Plateau of PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four isolates were separated into two clusters. Cluster I (strains 785T and 208) had the greatest 16S rRNA gene sequence similarity to Arthrobacter citreus (98.6 and 98.7 %, respectively), Arthrobacter luteolus (98.0 and 98.1%, respectively), Arthrobacter gandavensis (97.9 and 98.0 %, respectively) and Arthrobacter koreensis (97.6 and 97.7 %, respectively). Likewise, cluster II (strains J391T and J915) had the highest sequence similarity to Arthrobacter ruber (98.6 and 98.3 %, respectively) and Arthrobacter agilis (98.1 and 97.9  %, respectively). Average nucleotide identity and the digital DNA–DNA hybridization values illustrated that the two type strains, 785T and J391T, represented two separate novel species that are distinct from all currently recognized species in the genus Arthrobacter . These strains had DNA G+C contents of 66.0–66.1 mol% (cluster I) and 68.0 mol% (cluster II). The chemotaxonomic properties of strains 785T and J391T were in line with those of the genus Arthrobacter : anteiso-C15:0 (79.3 and 40.8 %, respectively) as the major cellular fatty acid, MK-8(H2) (65.8 %) or MK-9(H2) (75.6 %) as the predominant respiratory quinone, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycolipids and phospholipid, and A3α or A4α as the cell wall peptidoglycan type. On the basis of our results, two novel species in the genus Arthrobacter are proposed, namely Arthrobacter yangruifuii sp. nov. (type strain, 785T=CGMCC 1.16725T=GDMCC 1.1592T=JCM 33491T) and Arthrobacter zhaoguopingii sp. nov. (type strain, J391T=CGMCC 1.17382T=GDMCC 1.1667T=JCM 33841T).

Wide Range

Members of the metabolically diverse order Nitrosomonadales inhabit a wide range of environments. Two strains affiliated with this order were isolated from soils in Germany and characterized by a polyphasic approach. Cells of strains 0125_3T and Swamp67T are Gram-negative rods, non-motile, non-spore-forming, non-capsulated and divide by binary fission. They tested catalase-negative, but positive for cytochrome c-oxidase. Both strains form small white colonies on agar plates and grow aerobically and chemoorganotrophically on SSE/HD 1 : 10 medium, preferably utilizing organic acids and proteinaceous substrates. Strains 0125_3T and Swamp67T are mesophilic and grow optimally without NaCl addition at slightly alkaline conditions. Major fatty acids are C16 : 1  ω7c, C16 : 0 and C14 : 0. The major polar lipids are diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyglycerol. The predominant respiratory quinone is Q-8. The G+C content for 0125_3T and Swamp67T was 67 and 66.1 %, respectively. The 16S rRNA gene analysis indicated that the closest relatives (<91 % sequence similarity) of strain 0125_3T were Nitrosospira multiformis ATCC 25196T, Methyloversatilis universalis FAM5T and Denitratisoma oestradiolicum AcBE2-1T, while Nitrosospira multiformis ATCC 25196T, Nitrosospira tenuis Nv1T and Nitrosospira lacus APG3T were closest to strain Swamp67T. The two novel strains shared 97.4 % 16S rRNA gene sequence similarity with one another and show low average nucleotide identity of their genomes (83.8 %). Based on the phenotypic, chemotaxonomic, genomic and phylogenetic analysis, we propose the two novel species Usitatibacter rugosus sp. nov (type strain 0125_3T=DSM 104443T=LMG 29998T=CECT 9241T) and Usitatibacter palustris sp. nov. (type strain Swamp67T=DSM 104440T=LMG 29997T=CECT 9242T) of the novel genus Usitatibacter gen. nov., within the novel family Usitatibacteraceae fam. nov.

A non-motile, yellow–orange-pigmented bacterial strain, designated HME6664T, was isolated from Lake Soyang, Republic of Korea. The major fatty acids of strain HME6664T were summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 44.7 %) and iso-C15 : 0 (20.2 %). The DNA G+C content was 40.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME6664T formed a lineage within the genus Mucilaginibacter . Strain HME6664T was closely related to Mucilaginibacter ximonensis (96.7 %), Mucilaginibacter dorajii (96.5 %) and Mucilaginibacter lappiensis (96.3 %). On the basis of the evidence presented in this study, strain HME6664T represents a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter soyangensis sp. nov., is proposed. The type strain is HME6664T ( = KCTC 23261T = CECT 7824T).

Two Gram-stain-negative, non-fermentative bacterial strains, designated 11-0202T and 11-0607, were isolated from soil in South Korea, and four others, LUH 13522, LUH 8638, LUH 10268 and LUH 10288, were isolated from a beet field in Germany, soil in the Netherlands, and sediment of integrated fish farms in Malaysia and Thailand, respectively. Based on 16S rRNA, rpoB and gyrB gene sequences, they are considered to represent a novel species of the genus Acinetobacter . Their 16S rRNA gene sequences showed greatest pairwise similarity to Acinetobacter beijerinckii NIPH 838T (97.9–98.4 %). They shared highest rpoB and gyrB gene sequence similarity with Acinetobacter johnsonii DSM 6963T and Acinetobacter bouvetii 4B02T (85.4–87.6 and 78.1–82.7 %, respectively). Strain 11-0202T displayed low DNA–DNA reassociation values (<40 %) with the most closely related species of the genus Acinetobacter . The six strains utilized azelate, 2,3-butanediol, ethanol and dl-lactate as sole carbon sources. Cellular fatty acid analyses showed similarities to profiles of related species of the genus Acinetobacter : summed feature 3 (C16 : 1ω7c, C16 : 1ω6c; 24.3–27.2 %), C18 : 1ω9c (19.9–22.1 %), C16 : 0 (15.2–22.0 %) and C12 : 0 (9.2–14.2 %). On the basis of the current findings, it is concluded that the six strains represent a novel species, for which the name Acinetobacter kookii sp. nov. is proposed. The type strain is 11-0202T ( = KCTC 32033T = JCM 18512T).

A polyphasic analysis was undertaken of seven independent isolates of Gram-negative cocci collected from pathological clinical samples from New York, Louisiana, Florida and Illinois and healthy subgingival plaque from a patient in Virginia, USA. The 16S rRNA gene sequence similarity among these isolates was 99.7–100 %, and the closest species with a validly published name was Neisseria lactamica (96.9 % similarity to the type strain). DNA–DNA hybridization confirmed that these isolates are of the same species and are distinct from their nearest phylogenetic neighbour, N. lactamica . Phylogenetic analysis of 16S and 23S rRNA gene sequences indicated that the novel species belongs in the genus Neisseria . The predominant cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C18 : 1ω7c. The cellular fatty acid profile, together with other phenotypic characters, further supports the inclusion of the novel species in the genus Neisseria . The name Neisseria oralis sp. nov. (type strain 6332T  = DSM 25276T  = LMG 26725T) is proposed.

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.

Members of the genus Sneathia are fastidious bacteria that predominantly colonise the female genital tract and are significantly associated with reproductive disorders and genital and neonatal disease. From a taxonomical perspective, the genus only comprises the species Sneathia sanguinegens . Numerous reports on a second species, ‘Sneathia amnii’, have been published, but the name has never been validated. The same is the case for ‘Leptotrichia amnionii’, which was previously shown to belong to the same species as ‘Sneathia amnii’. We studied strains DSM 16631T and DSM 16630, which have been identified and deposited as ‘Leptotrichia amnionii’ previously. At the time of isolation, these strains were found to be most closely related to, but clearly different from, Sneathia sanguinegens based on 16S rRNA gene sequence similarities. Both strains proved to be almost indistinguishable from ‘Sneathia amnii’ based on molecular, morphological and physiological traits. The 16S rRNA gene sequence analysis revealed that strain DSM 16631T was assigned to the genus Sneathia with a sequence similarity of 95.47 % to Sneathia sanguinegens CCUG 41628T, followed by type strains of Caviibacter abscessus (93.03 %), Oceanivirga salmonicida (92.68 %) and Oceanivirga miroungae (91.97 %) as the next closely related members of the Leptotrichiaceae . The novel species was also clearly differentiated from other related taxa by core genome phylogeny, average nucleotide and amino acid identities, in silico DNA–DNA hybridization and MALDI-TOF MS. With respect to chemotaxonomic and physiological patterns, strains DSM 16631T and DSM 16630 were again highly similar to Sneathia sanguinegens . On the basis of these data, we propose the novel species Sneathia vaginalis sp. nov. with the type strain DSM 16631T (=CCUG 52977T=CCUG 52889AT) and a second strain DSM 16630 (=CCUG 52976=CCUG 52888) that were both isolated from bloodstream infections in women with puerperal fever in France. The G+C content of the DNA of the type strain is 28.4 mol% and the genome size is 1.28 Mbp. Based on the observed extremely high similarities of genotypic and phenotypic traits of the novel proposed species to those reported for ‘Sneathia amnii’, we recommend using this new name in all further publications on this taxon.

A novel nitrogen-fixing strain, designated HL-12T, was isolated from a freshwater lake in Taiwan. Cells of strain HL-12T were aerobic, Gram-negative, motile rods that were surrounded by a thick capsule, contained poly-β-hydroxybutyrate granules, and formed light-yellow to brownish-red colonies. Growth occurred at 15–40 °C (optimum 25–35 °C), at pH 6.0–7.0 (optimum pH 6.0) and with 0–4 % NaCl (optimum 0–1 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HL-12T belonged to the genus Derxia and exhibited 99.1 and 98.8 % 16S rRNA gene sequence similarity, respectively, with Derxia gummosa IAM 14990 and D. gummosa IAM 13946T. The major fatty acids (>10 %) of strain HL-12T were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c. The cellular hydroxy fatty acids were C12 : 0 3-OH, C14 : 0 2-OH and C14 : 0 3-OH. The isoprenoid quinone was Q-8 and the DNA G+C content was 72.0 mol%. The polar lipid profile contained phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several unknown aminophospholipids and phospholipids. DNA–DNA relatedness between strain HL-12T and LMG 3975 and LMG 3977T was <70 %. On the basis of the genotypic and phenotypic data, strain HL-12T represents a novel species in the genus Derxia , for which the name Derxia lacustris sp. nov. is proposed. The type strain is HL-12T ( = BCRC 80208T  = KCTC 23311T).

A thermophilic bacterium, designated DX-1T, was isolated from the anode biofilm of a microbial fuel cell (MFC). Cells of strain DX-1T were oxidase-positive, catalase-positive and Gram-staining-negative. The strain was found to be rod-shaped and non-motile and to produce subterminal spores. The strain was able to grow with NaCl at concentrations ranging from 0 to 6 %, at temperatures of 25–60 °C (optimum 55 °C) and pH 6.0–8.0 (optimum pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DX-1T formed a cluster with Ureibacillus thermosphaericus DSM 10633T (96.9 % 16S rRNA sequence similarity), Ureibacillus composti DSM 17951T (95.8 %), Ureibacillus thermophilus DSM 17952T (95.7 %) and Ureibacillus terrenus DSM 12654T (95.3 %). The G+C content of the genomic DNA was 40.4 mol%. The major quinone was MK-7, the peptidoglycan type was l-Lys←d-Asp, and the major cellular fatty acids (>5 %) were iso-C16 : 0 and iso-C14 : 0. The polar lipids consisted of phosphatidylglycerol, diphosphatidylglycerol and phospholipids of unknown composition. Based on phenotypic characteristics, chemotaxonomic features and results of phylogenetic analyses, the strain was determined to represent a distinct novel species of the genus Ureibacillus , and the name proposed for the novel species is Ureibacillus defluvii sp. nov., with type strain DX-1T ( = CGMCC 1.12358T = KCTC 33127T).
