A non-lipophilic, coryneform bacterium isolated from a patient's wound caused by a dog bite was characterized by phenotypic, chemotaxonomic and molecular genetic methods. Chemotaxonomic features suggested assignment of the unknown bacterium to the genus Corynebacterium. The isolate exhibited the following unusual features, which made it possible to phenotypically differentiate it from all other medically relevant corynebacteria: the Gram stain showed some very filamentous rods (>15 μm in length); some cells exhibited branching; colonies were domed and adherent to agar; the micro-organism was positive for pyrazinamidase, β-glucosidase, α-glucosidase and trypsin but negative for β-galactosidase. 16S rRNA gene sequencing and partial rpoB gene sequencing showed that the closest phylogenetic relative, Corynebacterium freiburgense, exhibited more than 1.9 % and 17.9 % divergence with the unknown bacterium, respectively. Based on both phenotypic and molecular genetic data, it is proposed that the isolate should be classified as a novel species, Corynebacterium canis sp. nov., with the type strain 1170T (=CCUG 58627T =DSM 45402T).

Morphological, biochemical and molecular genetic studies were carried out on an unknown non-spore-forming, Gram-negative, rod-shaped bacterium which was isolated from dog faeces. The bacterium grew under anaerobic conditions, was asaccharolytic, resistant to 20 % (v/v) bile and was oxidase- and urease-negative. Phylogenetic analysis based on comparative 16S rRNA gene sequencing showed that the unidentified bacterium clustered with Sutterella wadsworthensis, although a sequence divergence of >5 % indicated that the bacterium from dog faeces represented a previously unrecognized subline within the genus. On the basis of the presented findings, a novel species, Sutterella stercoricanis sp. nov., is described. The type strain of Sutterella stercoricanis is 5BAC4T (=CCUG 47620T=CIP 108024T).

A polyphasic taxonomic study was performed on an uncharacterized Gram-positive, catalase-negative, elongated coccus-shaped bacterium isolated from a swine-manure storage pit. The bacterium, designated strain PPC9T, was facultatively anaerobic and had a DNA G+C content of 44.5 mol%. Comparative 16S rRNA gene sequencing indicated that the bacterium represented a novel subline within the genus Vagococcus, close to but distinct from Vagococcus lutrae. Strain PPC9T was readily distinguished from the five recognized species of the genus Vagococcus by using biochemical tests and molecular genetic analysis. Based on phylogenetic and phenotypic evidence strain PPC9T is considered to represent a novel species of the genus Vagococcus, for which the name Vagococcus elongatus sp. nov. is proposed. The type strain is PPC9T (=CCUG 51432T=NRRL B-41357T).

A novel bacterial strain, designated SA3-7T, was isolated from soil of a lava forest located in Jeju, Republic of Korea. Cells of strain SA3-7T were Gram-stain-negative, oxidase- and catalase-positive, non-motile rods and produced creamy white colonies on ten-fold-diluted R2A agar. The isolate contained menaquinone-7 (MK-7) as the predominant isoprenoid quinone and summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The DNA G+C content was 43.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain SA3-7T was related most closely to Mucilaginibacter frigoritolerans FT22T (96.7 % sequence similarity) and that it formed a separate lineage in the genus Mucilaginibacter . Combined phenotypic, chemotaxonomic and phylogenetic characteristics supported the conclusion that strain SA3-7T represents a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter gotjawali sp. nov. is proposed; the type strain is SA3-7T ( = KCTC 32515T = CECT 8628T = DSM 29289T).

A pigmented, slowly growing Mycobacterium avium complex AccuProbe-positive organism was isolated from the sputum and pleural fluid of a 72-year-old female with bronchiectasis. The unusual morphology of the organism prompted further identification by 16S rRNA gene sequencing, revealing a perfect identity with previously uncharacterized strain Mycobacterium sp. MCRO 8 (GenBank accession no. X93034), with the closest established species by 16S rDNA analysis being Mycobacterium interjectum. HPLC of the organism corresponded to previously obtained patterns identified as M. interjectum-like and, upon sequence evaluation of a selection of strains with a similar profile, more were subsequently identified as MCRO 8. A total of 16 strains isolated from human respiratory samples were evaluated in the characterization of this novel species, for which the name Mycobacterium saskatchewanense sp. nov. is proposed. The type strain is strain 00-250T (=ATCC BAA-544T=DSM 44616T=CIP 108114T).

A xylanolytic bacterium, US15T, was isolated from swamp forest soil in Ulsan, Korea. The cells of the novel strain were Gram-positive, non-motile, short-rod-shaped and showed chemotaxonomic properties that were consistent with its classification in the genus Microbacterium. Chemotaxonomic results showed MK-12 and MK-11 as major menaquinones, predominating iso- and anteiso-branched cellular fatty acids, glucose, galactose and mannose as cell-wall sugars, peptidoglycan-type B2β with glycolyl residues and a DNA G+C content of 66·5 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain US15T was closely related to Microbacterium arborescens IFO 3750T, Microbacterium imperiale IFO 12610T and Microbacterium ulmi LMG 20991T (96·9, 96·8 and 96·2 % similarities, respectively), and formed a separate lineage within the genus Microbacterium. Combined genotypic and phenotypic data showed that strain US15T (=DSM 16915T=KCTC 19080T) merits recognition as the type strain of a novel species within the genus Microbacterium, for which the name Microbacterium paludicola sp. nov. is proposed.

A total of 14 Halomonas strains were isolated from the blood of two patients and from dialysis machines of a renal care centre. The strains were Gram-negative, halophilic, motile and non-spore-forming rods. They produced cream-coloured colonies and contained Q-9 as the predominant ubiquinone and C18 : 1 ω7c and C16 : 0 as the major fatty acids. Phylogenetic analysis based on 16S rRNA gene sequencing showed that the 14 isolates were most closely related to Halomonas magadiensis 21 MIT with 98.1–98.9 % sequence similarity and that they formed three separate lineages among themselves. Combined phenotypic and DNA–DNA hybridization data support the conclusion that they represent three novel species of the genus Halomonas, for which the names Halomonas stevensii sp. nov. (type strain S18214T=KCTC 22148T=DSM 21198T), Halomonas hamiltonii sp. nov. (type strain W1025T=KCTC 22154T=DSM 21196T) and Halomonas johnsoniae sp. nov.

A novel, strictly aerobic, heterotrophic, gliding, Gram-negative, oxidase-, catalase-, β-galactosidase- and alkaline phosphatase-positive marine bacterium, designated strain KMM 6220T, was isolated from seawater and studied by using a polyphasic taxonomic approach. The DNA G+C content of strain KMM 6220T was 59.9 mol%. The predominant fatty acids were iso-C15 : 1, iso-C15 : 0, iso-C15 : 0 3-OH, iso-C17 : 0 3-OH and C16 : 1 ω7/iso-C15 : 0 2-OH. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that strain KMM 6220T formed a cluster with the misclassified strains [Flexibacter] aggregans NBRC 15974 and [Flexibacter] tractuosus NBRC 16035 and with the type strains of Reichenbachiella agariperforans and Roseivirga ehrenbergii with levels of similarity of 95.9, 94.4, 92.0 and 91.8 %, respectively. On the basis of its phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, strain KMM 6220T is considered to represent a novel species of a new genus in the phylum Bacteroidetes, for which the name Fulvivirga kasyanovii gen. nov., sp. nov. is proposed. The type strain of the type species is KMM 6220T (=CCTCC AB 206119T=KCTC 12832T).

Three strains of an unidentified Gram-stain-variable, fastidious, catalase-negative, capnophilic, non-spore-forming, coccus-shaped bacterium from human wound specimens were characterized by phenotypic and molecular taxonomic methods. Initially, these strains were anaerobic; with repeated culture, they became aerotolerant. Comparative 16S rRNA gene sequencing studies demonstrated that the unknown strains were genealogically homogeneous and constituted a novel subline within the genus Gemella. The unknown bacterium was readily distinguished from other Gemella species by biochemical tests. On the basis of both phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium from clinical specimens be classified as Gemella asaccharolytica sp. nov. The type strain is WAL 1945JT (=ATCC BAA-1630T =CCUG 57045T).
