A Gram-negative, oxidase-positive, catalase-negative, facultatively anaerobic, motile, curved rod-shaped bacterium, strain N384T, was isolated from a marine sponge (Scleritoderma cyanea; phylum Porifera) collected from a depth of 795 feet (242 m) off the west coast of Curaçao. On the basis of 16S rRNA gene sequencing, strain N384T was shown to belong to the genus Vibrio , most closely related to Vibrio brasiliensis LMG 20546T (98.8 % similarity), Vibrio nigripulchritudo ATCC 27043T (98.5 %), Vibrio tubiashii ATCC 19109T (98.6 %) and V. sinaloensis DSM 21326T (98.2 %). The DNA G+C content of strain N384T was 41.6 mol%. An analysis of concatenated sequences of five genes (gyrB, rpoA, pyrH, mreB and ftsZ; 4068 bp) demonstrated a clear separation between strain N384T and its closest neighbours and clustered strain N384T into the ‘Orientalis’ clade of vibrios. Phenotypically, the novel species belonged to the arginine dihydrolase-positive, lysine decarboxylase- and ornithine decarboxylase-negative (A+/L−/O−) cluster. The novel species was also differentiated on the basis of fatty acid composition, specifically that the proportions of iso-C13 : 0, iso-C15 : 0, C15 : 0, iso-C16 : 0, C16 : 0, iso-C17 : 0, C17 : 1ω8c and C17 : 0 were significantly different from those found in V. brasiliensis and V. sinaloensis . The results of DNA–DNA hybridization, average nucleotide identity and physiological and biochemical tests further allowed differentiation of this strain from other described species of the genus Vibrio . Collectively, these findings confirm that strain N384T represents a novel Vibrio species, for which the name Vibrio caribbeanicus sp. nov. is proposed, with the type strain N384T ( = ATCC BAA-2122T = DSM 23640T).

Strains originating from various sources and classified as members of the genus Citrobacter within the family Enterobacteriaceae were characterized by sequencing internal portions of genes rpoB, fusA, pyrG and leuS, 16S rRNA gene sequencing, average nucleotide identity (ANI) of genomic sequences and biochemical tests. Phylogenetic analysis based on the four housekeeping genes showed that the 11 species of the genus Citrobacter with validly published names are well demarcated. Strains CIP 55.13T and CIP 55.9 formed a distinct branch associated with Citrobacter youngae . The ANI between CIP 55.9 and CIP 55.13T was 99.19 %, whereas it was 94.75 % between CIP 55.13T and strain CIP 105016T of the species C. youngae , the most closely related species. Biochemical characteristics consolidated the fact that the two isolates represent a separate species, for which the name Citrobacter pasteurii sp. nov. is proposed. The type strain is CIP 55.13T ( = DSM 28879T = Na 1aT).

A Gram-stain-negative, rod-shaped, motile via polar flagellum, facultatively aerobic, light-yellow, bacterium (designated 188UL20-2T) was isolated from a mussel sample of Mytilus coruscus collected on Ulleung Island, Ulleung-gun, Gyeongsangbuk-do, Republic of Korea. On the basis of 16S rRNA gene sequencing results, strain 188UL20-2T clustered with species of the genus Vibrio and appeared closely related to Vibrio marisflavi DSM 23086T (96.59%), Vibrio variabilis DSM 26147T (96.57%), Vibrio penaeicida DSM 14398T (96.37%) and Vibrio litoralis DSM 17657T (95.97%). The average nucleotide identity and digital DNA–DNA hybridization values between strain 188UL20-2T and its closest related strain were 71.3 and 16.4%, indicating that 188UL20-2T represents a novel species of the genus Vibrio . Growth occurred at 18–37 °C on MA medium in the presence of 1–4% NaCl (w/v) and at pH 5.0–10.0. The DNA G+C content of the genomic DNA was 45.4 mol%, and ubiquinone-8 (Q-8) was the major respiratory quinone. The major cellular fatty acids (>5%) were C16:1 ω6c and/or C16:1 ω7c (summed feature 3), C18:1 ω7c and/or C18:1 ω6c (summed feature 8), C16:0, C16:0 iso, C14:0, C14:0 iso and C12:0. The polar lipids consisted of phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids, unidentified aminophospholipid, unidentified glycolipid and seven unidentified lipids. Physiological and biochemical characteristics indicated that strain 188UL20-2T represents a novel species of the genus Vibrio , for which the name Vibrio ulleungensis sp. nov. is proposed. The type strain is 188UL20-2T (=KACC 22258T=LMG 32202T).

A novel strain, yH16, was isolated on nutrient agar from soil samples collected at KyungHee University, Suwon City, Republic of Korea. Cells of strain yH16T were short rods, Gram-negative-staining, motile and non-spore-forming, with a polar flagellum. Biochemical and molecular characterization revealed that this strain was most similar to Pseudogulbenkiania subflava BP-5T. Further 16S rRNA gene sequencing studies revealed that the new strain clustered with Pseudogulbenkiania subflava BP-5T (95.9 % similarity), Paludibacterium yongneupense 5YN8-15T (95.2 % similarity), Gulbenkiania mobilis E4FC31-5T (94.6 % similarity) and Chromobacterium aquaticum CC-SE-YA-1T (93.9 % similarity). The isolate was able to grow at 25–40 °C, 0.3–2 % NaCl and pH 5.5–7. The DNA G+C content was 65.9±1.0 mol%. The predominant fatty acids were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C16:0. Ubiquinone 8 was the major respiratory quinone. It was evident from the data obtained that the strain should be classified as a novel species of the genus Pseudogulbenkiania . The name proposed for this taxon is Pseudogulbenkiania gefcensis sp. nov., and the type strain is yH16T ( = KCCM 90100T = JCM 17850T).

Several Gram-negative-staining, facultatively anaerobic bacterial isolates were obtained from Eucalyptus seedlings showing symptoms of bacterial blight and dieback in Colombia, Rwanda and South Africa. Partial 16S rRNA gene sequencing, together with partial gyrB sequencing, placed the isolates in the genus Pantoea and indicated that they constituted three novel species. Multilocus sequence analysis (MLSA) based on partial sequences of gyrB, rpoB, infB and atpD revealed Pantoea dispersa , Pantoea eucrina and Pantoea cypripedii as their closest phylogenetic relatives. DNA–DNA hybridization studies confirmed the classification of the new isolates as three novel species and phenotypic tests allowed them to be differentiated from their closest phylogenetic neighbours. The names Pantoea rodasii sp. nov. [type strain LMG 26273T = BD 943T (deposited with the Plant Pathogenic and Plant Protecting Bacteria Collection, South Africa) = BCC 581T (deposited with the Bacterial Culture Collection, Forestry and Agricultural Institute, South Africa)], Pantoea rwandensis sp. nov.

A novel Gram-stain-positive, non-motile, non-spore-forming coccus-shaped obligately anaerobic bacterium was recovered from a fecal sample obtained from an individual from a traditional community located on the southern coast of Peru. The results of analysis based on 16S rRNA gene sequencing indicated the novel bacterium to be phylogenetically distinct from other genera of members of the Peptoniphilaceae family, sharing a loose affinity with the genera Ezakiella , Finegoldia , Gallicola and Parvimonas . The major cellular fatty acids of the novel isolate were determined to be C16:0, C17:1ω8c, and C18:1ω9c. The DNA G+C content was 29.9 mol%. End products of metabolism from peptone yeast glucose broth (PYG) were determined to be acetate and methyl succinate. The diagnostic diamino acid present in the cell wall was lysine. On the basis of the phenotypic, chemotaxonomic and phylogenetic results the organism is a member of a novel genus belonging to the family Peptoniphilaceae for which the name Citroniella saccharovorans gen nov. sp. nov., is proposed. The type strain is M6.X9T (DSM 29873T=CCUG 66799T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

Four Gram-positive, catalase-negative, coccoid isolates that were obtained from donkey oral cavities formed two distinct clonal groups when characterized by phenotypic and phylogenetic studies. From the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genus Streptococcus . Two of the isolates were related most closely to Streptococcus ursoris with 95.6 % similarity based on the 16S rRNA gene and to Streptococcus ratti with 92.0 % similarity based on the 60 kDa heat-shock protein gene (groEL). The other two isolates, however, were related to Streptococcus criceti with 95.0 and 89.0 % similarities based on the 16S rRNA and groEL genes, respectively. From both phylogenetic and phenotypic evidence, the four isolates formed two distinct clonal groups and are suggested to represent novel species of the genus Streptococcus . The names proposed for these organisms are Streptococcus orisasini sp. nov. (type strain NUM 1801T = JCM 17942T = DSM 25193T) and Streptococcus dentasini sp. nov. (type strain NUM 1808T = JCM 17943T = DSM 25137T).

A Gram-stain-negative, facultatively anaerobic, non-motile and coccoid- to short-rod-shaped bacterium, designated strain Dys-CH1T, was isolated from the hindgut of a fungus-growing termite Macrotermes barneyi. The optimal pH and cultivation temperature of strain Dys-CH1T were pH 7.2–7.6 and 35–37 °C, respectively. Sequence analysis of 16S rRNA gene showed that Dys-CH1T shared 94.6 % and 90.9 % similarity with Dysgonomonas capnocytophagoides JCM 16697T and Dysgonomonas gadei CCUG 42882T, respectively. Strain Dys-CH1T was found to be different from other species of the genus Dysgonomonas with validly published names with respect to taxonomically important traits, including habitat, biochemical tests, DNA G+C content, bile resistance, fatty-acid composition and susceptibility to antimicrobial agents. On the basis of these characteristics, strain Dys-CH1T represents a novel species of the genus Dysgonomonas for which the name Dysgonomonas macrotermitis sp. nov. is proposed. The type strain is Dys-CH1T ( = JCM 19375T = DSM 27370T).

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.

Four Gram-stain-positive, catalase-negative, coccoid-shaped organisms were isolated from elephant oral cavities. The isolates were tentatively identified as streptococcal species based on the results of biochemical tests. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genus Streptococcus . Two isolates (NUM 6304T and NUM 6312) were related most closely to Streptococcus salivarius with 96.8 % and 93.1 % similarity based on the 16S rRNA gene and the RNA polymerase β subunit encoding gene (rpoB), respectively, and to Streptococcus vestibularis with 83.7 % similarity based on the 60 kDa heat-shock protein gene (groEL). The other two isolates (NUM 6306T and NUM 6318) were related most closely to S. vestibularis with 97.0 % and 82.9 % similarity based on the 16S rRNA and groEL genes, respectively, and to S. salivarius with 93.5 % similarity based on the rpoB gene. Based on phylogenetic and phenotypic evidence, these isolates are suggested to represent novel species of the genus Streptococcus , for which the names Streptococcus loxodontisalivarius sp. nov. (type strain NUM 6304T = JCM 19287T = DSM 27382T) and Streptococcus saliviloxodontae sp. nov. (type strain NUM 6306T = JCM 19288T = DSM 27513T) are proposed.
