A Gram-negative bacterium, designated AD8T, was isolated from a tidal flat of the Taean coast in South Korea. Cells were strictly aerobic, motile, ovoid rods or rods, with two lateral flagella on one side. Strain AD8T was catalase- and oxidase-positive and able to oxidize thiosulfate and reduce nitrate to nitrite. Growth of strain AD8T was observed at 15–40 °C (optimum 25–30 °C), at pH 5.0–9.5 (optimum pH 6.0–7.5) and with 1.0–11.0 % (w/v) NaCl (optimum 2.0–4.0 %). The predominant fatty acids were C18 : 1ω7c and C19 : 0 cyclo ω8c. The G+C content of the genomic DNA was 67.5 mol% and the major quinone was Q-10. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain AD8T belonged to the genus Citreicella and was most closely related to Citreicella marina CK-I3-6T within the class Alphaproteobacteria (96.9 % 16S rRNA gene sequence similarity). On the basis of phenotypic, chemotaxonomic and phylogenetic analysis, strain AD8T represents a novel species within the genus Citreicella, for which the name Citreicella aestuarii sp. nov. is proposed. The type strain is AD8T ( = KACC 13699T  = DSM 22011T).

Three isolates originating from Spanish-style green-olive fermentations in a manufacturing company in the province of Seville, Spain, were taxonomically characterized by a polyphasic approach. This included a phylogenetic analysis based on 16S rRNA gene sequences and multi-locus sequence analysis (MLSA) based on pyrH, recA, rpoA, gyrB and mreB genes. The isolates shared 98.0 % 16S rRNA gene sequence similarity with Vibrio xiamenensis G21T. Phylogenetic analysis based on 16S rRNA gene sequences using the neighbour-joining and maximum-likelihood methods showed that the isolates fell within the genus Vibrio and formed an independent branch close to V. xiamenensis G21T. The maximum-parsimony method grouped the isolates to V. xiamenensis G21T but forming two clearly separated branches. Phylogenetic trees based on individual pyrH, recA, rpoA, gyrB and mreB gene sequences revealed that strain IGJ1.11T formed a clade alone or with V. xiamenensis G21T. Sequence similarities of the pyrH, recA, rpoA, gyrB and mreB genes between strain IGJ1.11T and V. xiamenensis G21T were 86.7, 85.7, 97.3, 87.6 and 84.8 %, respectively. MLSA of concatenated sequences showed that strain IGJ1.11T and V. xiamenensis G21T are two clearly separated species that form a clade, which we named Clade Xiamenensis, that presented 89.7 % concatenated gene sequence similarity, i.e. less than 92 %. The major cellular fatty acids (>5 %) of strain IGJ1.11T were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). Enzymic activity profiles, sugar fermentation patterns and DNA G+C content (52.9 mol%) differentiated the novel strains from the closest related members of the genus Vibrio. The name Vibrio olivae sp. nov. is proposed for the novel species. The type strain is IGJ1.11T ( = CECT 8064T = DSM 25438T).

A novel, moderately halophilic, Gram-positive coccus, designated strain S2R53-5T, was isolated from jeotgal, a traditional Korean fermented seafood. The organism was strictly aerobic, non-motile, non-sporulating and catalase- and oxidase-positive. Strain S2R53-5T grew in the presence of 0.5–15 % (w/v) NaCl and at pH 6.5–11.0, with optimum growth at 5 % (w/v) NaCl and pH 7.0. The temperature range for growth was 20.0–30.0 °C, with an optimum temperature of 30 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2R53-5T belongs to the family Staphylococcaceae and was most closely related to Salinicoccus roseus DSM 5351T (96.8 % gene sequence similarity), Salinicoccus hispanicus DSM 5352T (96.1 %), Salinicoccus alkaliphilus T8T (95.2 %) and Jeotgalicoccus halotolerans YKJ-101T (95.1 %). The genomic DNA G+C content was 47.0 mol%, which is in the range of 46–51 mol% that is characteristic for the genus Salinicoccus. Levels of DNA–DNA relatedness between strain S2R53-5T and S. roseus DSM 5351T, S. hispanicus DSM 5352T and S. alkaliphilus KCTC 13928T were 32.2, 15.4 and 4.6 %, respectively. Chemotaxonomic data (major menaquinone, MK-6; major fatty acids, iso-C15 : 0 and anteiso-C15 : 0; cell-wall murein type, Lys and Gly) and 16S rRNA gene sequence analysis supported the affiliation of strain S2R53-5T with the genus Salinicoccus. The combined evidence from the low DNA–DNA relatedness, physiological, biochemical and other genotypic data indicate that strain S2R53-5T clearly represents a novel species of the genus Salinicoccus, for which the name Salinicoccus jeotgali sp. nov. is proposed. The type strain is S2R53-5T (=KCTC 13030T=LMG 23640T).

Two strains of Gram-stain-positive, aerobic, spore-forming and rod-shaped bacteria, designated U13T and U14, were isolated from soil of the Ukraine. Comparative analysis of the 16S rRNA gene sequences indicated that these strains belong to the genus Tumebacillus, with the highest 16S rRNA gene sequence similarity with Tumebacillus ginsengisoli Gsoil 1105T (95.48 % and 95.49 %, respectively). Strains U13T and U14 had iso-C15 : 0 and summed features 1 and 4 as the main fatty acids, and were able to grow at pH ranging from pH 5.0 to 9.0 (optimum pH 6.0–7.0), temperatures ranging from 25 to 42 °C (optimum 28–37 °C) and with 0–1 % (w/v) NaCl (optimum 0 %, w/v) on R2A agar medium. Chemotaxonomic data revealed that the cell-wall peptidoglycan type of the two strains was type A1γ (meso-diaminopimelic acid). On the basis of the evidence from this study, strains U13T and U14 represent a novel species of the genus Tumebacillus, for which the name Tumebacillus luteolus sp. nov. is proposed. The type strain is U13T ( = KEMB 7305-100T = JCM 19866T) and a second strain is U14 ( = KEMB 7305-101 = JCM 19867).

A Gram-negative, motile, non-spore-forming and lipolytic bacterial strain, designated Gung47T, was isolated from a tidal flat on the west coast of Korea. Strain Gung47T grew optimally at 30 °C and with 2−5 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain Gung47T belonged to the genus Photobacterium. Strain Gung47T exhibited 98.1 % 16S rRNA gene sequence similarity with Photobacterium rosenbergii LMG 22223T and 94.3–96.3 % similarity with other type strains of species of the genus Photobacterium. Strain Gung47T exhibited 47 % DNA–DNA relatedness to P. rosenbergii LMG 22223T. Strain Gung47T contained Q-8 as the predominant ubiquinone and C16 : 1 ω7c and/or iso-C15 : 0 2-OH, C16 : 0 and C18 : 1 ω7c as the major fatty acids. In this study, two closely related type strains, P. rosenbergii LMG 22223T and Photobacterium halotolerans LMG 22194T, were also found to have Q-8 as the predominant ubiquinone. The DNA G+C content of strain Gung47T was 50.6 mol%. The differential phenotypic properties together with the phylogenetic and genetic distinctiveness of strain Gung47T demonstrated that this strain is distinguishable from recognized Photobacterium species. Therefore, strain Gung47T is considered to represent a novel species of the genus Photobacterium, for which the name Photobacterium gaetbulicola sp. nov. is proposed. The type strain is Gung47T (=KCTC 22804T =CCUG 58399T).

Tidal Flat Sediment

Two moderately halotolerant Gram-negative bacteria were isolated from tidal flat sediment of the South Sea in Korea (the Korea Strait). The strains, designated M9T and M18T, were strictly aerobic, rod-shaped and non-spore-forming and motile with a flagellum and their major fatty acids were C16 : 0 and C19 : 0 cyclo ω8c. Strains M9T and M18T could grow in the presence of up to 13–15 % (w/v) NaCl, but their optimum salt concentrations were relatively low (0–3 %, w/v). The major predominant isoprenoid quinone was Q-8 and the G+C content of the genomic DNA was 57–58 mol%. Phylogenetic analyses and comparative 16S rRNA gene sequence studies revealed that strains M9T and M18T formed a phylogenetic lineage distinct from the genus Teredinibacter within the class Gammaproteobacteria and were most closely related to the genera Microbulbifer, Saccharophagus and Teredinibacter, with less than 92·5 % 16S rRNA gene sequence similarity. The level of 16S rRNA gene sequence similarity between the two strains was 96·7 %. On the basis of physiological and phylogenetic properties, strains M9T and M18T represent separate species within a novel genus of the class Gammaproteobacteria, for which the names Marinimicrobium koreense gen. nov., sp. nov. (type species) and Marinimicrobium agarilyticum sp. nov. are proposed. The type strains of Marinimicrobium koreense and Marinimicrobium agarilyticum are M9T (=KCTC 12356T=DSM 16974T) and M18T (=KCTC 12357T=DSM 16975T), respectively.
