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).

A bacterial strain, DC-186T, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 °C and pH 5.5–8.0. Strain DC-186T was positive in tests for catalase, oxidase and β-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C16 : 1/iso-C15 : 0 2-OH (42 %) and iso-C15 : 0 (26 %), the major respiratory quinone was menaquinone-7 and the genomic DNA G+C content was 42 mol%. 16S rRNA gene sequence analysis and phenetic characterization indicated that this organism belongs to the phylum Bacteroidetes and revealed its affiliation to the family Sphingobacteriaceae. Of recognized taxa, strain DC-186T was most closely related to Sphingobacterium daejeonense (90 % sequence similarity) based on 16S rRNA gene sequence analysis. The low 16S rRNA gene sequence similarity with other recognized taxa and the identification of distinctive phenetic features for this isolate support the definition of a new genus within the family Sphingobacteriaceae. The name Pseudosphingobacterium domesticum gen. nov., sp. nov. is proposed, with strain DC-186T (=CCUG 54353T=LMG 23837T) as the type strain.

Two slightly halophilic bacterial strains, C1-52T and YD-9, were isolated from Daban and Aiding salt lakes in Xinjiang, China, respectively. The isolates were Gram-positive, non-endospore-forming, non-motile, facultatively anaerobic cocci. Colonies were pale yellow, and a light pink, diffusible pigment was produced after a few additional days of incubation. The isolates grew optimally with 2–3 % (w/v) NaCl, at pH 7.5 and at 30–35 °C. The peptidoglycan type was l-Lys–Gly3–4–l-Ala(Gly). The menaquinones were MK-7 (83.2 %) and MK-6 (16.8 %). The major fatty acids (>10 %) were anteiso-C15 : 0 and iso-C15 : 0. The DNA G+C content of strains C1-52T and YD-9 was 41.2 and 41.0 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains C1-52T and YD-9 were closely related to Jeotgalicoccus psychrophilus YKJ-115T (98.0 and 97.1 % 16S rRNA gene sequence similarity, respectively), followed by Jeotgalicoccus halotolerans YKJ-101T (97.1 and 96.8 %). Strains C1-52T and YD-9 shared, respectively, 20 and 11 % DNA–DNA relatedness with J. halotolerans JCM 11198T and 8 and 13 % with J. psychrophilus JCM 11199T. DNA–DNA relatedness between the isolates was 91 %. On the basis of phenotypic and phylogenetic distinctiveness, strains C1-52T and YD-9 belonged to the same species, which should be placed in the genus Jeotgalicoccus as a novel species. The name Jeotgalicoccus halophilus sp. nov. is proposed, with the type strain C1-52T ( = CGMCC 1.8911T  = NBRC 105788T).

A Gram-negative, motile, non-spore-forming bacterial strain, designated MJ07T, was isolated from a farm soil and was characterized to determine its taxonomic position by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ07T belongs to the family Alcaligenaceae, class Betaproteobacteria, and is related most closely to Pusillimonas ginsengisoli KCTC 22046T (98.6 % sequence similarity) and Pusillimonas noertemannii BN9T (96.9 %). The levels of 16S rRNA gene sequence similarity between strain MJ07T and members of all other recognized species of the family Alcaligenaceae were below 95.2 %. The G+C content of the genomic DNA of strain MJ07T was 59.4 mol%. The detection of a quinone system with ubiquinone Q-8 as the major respiratory lipoquinone, putrescine as the predominant polyamine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and two unknown aminolipids as major polar lipids and a fatty acid profile with C16 : 0 (32.0 %), C17 : 0 cyclo (24.7 %) and C19 : 0 cyclo ω8c (11.5 %) as the major components supported the affiliation of strain MJ07T to the genus Pusillimonas. Strain MJ07T exhibited relatively low levels of DNA–DNA relatedness with respect to P. ginsengisoli KCTC 22046T (50±8 %) and P. noertemannii KACC 13183T (18±7 %). On the basis of its phenotypic and genotypic properties together with its phylogenetic distinctiveness, strain MJ07T (=KCTC 22455T =JCM 16386T) should be classified in the genus Pusillimonas as the type strain of a novel species, for which the name Pusillimonas soli sp. nov. is proposed.

Two bacterial strains isolated from chicken caecum, C46T and C47, were characterized using a polyphasic taxonomic approach that included analysis of the phenotypic and biochemical features, cellular fatty acid profiles, menaquinone profiles and phylogenetic position (using 16S rRNA gene sequence analysis). The 16S rRNA gene sequence analysis showed that these strains belonged to the family Porphyromonadaceae. These strains shared 100 % 16S rRNA gene sequence similarity with each other and were related to Parabacteroides distasonis (showing 86 % sequence similarity). The strains were found to be obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative rods. Growth of the strains was inhibited on medium containing 20 % bile. The major menaquinones of the isolates were MK-11 and MK-12. This menaquinone composition was different from those of other genera of the family Porphyromonadaceae, such as Parabacteroides (in which the predominant menaquinones are MK-9 and MK-10), Porphyromonas (MK-9 and MK-10) and Tannerella (MK-10 and MK-11). This is an important chemotaxonomic characteristic of these micro-organisms. The DNA G+C content of strain C46T is 52.0 mol%. On the basis of these data, strains C46T and C47 represent a novel genus and species, for which the name Barnesiella viscericola gen. nov., sp. nov. is proposed. The type strain of Barnesiella viscericola is C46T (=JCM 13660T=DSM 18177T).

A Gram-negative, non-spore-forming, motile, facultatively anaerobic bacterium, designated strain MJ06T, was isolated from oil-contaminated soil and was characterized taxonomically by using a polyphasic approach. Strain MJ06T contained ubiquinone Q-8 as the major respiratory lipoquinone, putrescine as the predominant polyamine and phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol as major polar lipids. The G+C content of the genomic DNA of strain MJ06T was 66.2 mol%. The major fatty acids were summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH; 32.5 %), C16 : 0 (22.8 %) and summed feature 7 (one or more of C18 : 1 ω7c, C18 : 1 ω9t and C18 : 1 ω12t; 14.9 %). Comparative 16S rRNA gene sequence analysis showed that strain MJ06T belonged to the family Alcaligenaceae, class Betaproteobacteria, and joined the evolutionary radiation enclosed by the genus Castellaniella. Levels of 16S rRNA gene sequence similarity between strain MJ06T and its phylogenetically closest relatives, Castellaniella denitrificans NKNTAUT, Castellaniella defragrans 54PinT, Castellaniella ginsengisoli DCY36T and Castellaniella caeni Ho-11T, were 98.6, 98.3, 97.8 and 97.3 %, respectively. Levels of similarity between strain MJ06T and the type strains of all other recognized species in the family Alcaligenaceae were below 95.0 %. Strain MJ06T exhibited relatively low levels of DNA–DNA relatedness with respect to C. defragrans DSM 12141T (52 %), C. denitrificans DSM 11046T (31 %), C. ginsengisoli KCTC 22398T (18 %) and C. caeni KCTC 12197T (15 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ06T is considered to represent a novel species of the genus Castellaniella, for which the name Castellaniella daejeonensis sp. nov. is proposed. The type strain is MJ06T (=KCTC 22454T =JCM 16240T).

A novel strictly aerobic, orange-pigmented, Gram-stain-negative bacterium, designated strain GJ16T, was isolated from coastal seawater of Gangjin Bay, the southernmost part of the Korean peninsula, and subjected to a polyphasic taxonomic study. It grew optimally at 25–30 °C, at pH 7.0–8.0 and in the presence of 3 % NaCl. Comparative 16S rRNA gene sequence analysis revealed that strain GJ16T formed a distinct lineage within the family Flavobacteriaceae and shared less than 91.2 % 16S rRNA gene sequence similarity with members of the genera Leptobacterium, Zhouia, Winogradskyella, Dokdonia and Krokinobacter. The predominant cellular fatty acids were iso-C15 : 0 (40.2 %), iso-C15 : 1 G (12.8 %), iso-C17 : 0 3-OH (11.2 %) and C15 : 0 (6.6 %). The G+C content of the genomic DNA was 39.4 mol% and the major respiratory isoprenoid quinone was MK-6. On the basis of phenotypic and genotypic data, strain GJ16T represents a novel species in a new genus in the family Flavobacteriaceae, for which the name Gangjinia marincola gen. nov., sp. nov. is proposed; the type strain is GJ16T (=KCTC 22649T =JCM 16082T).

A Gram-negative bacterium, designated P2T, was isolated from the biofilm developed on the inner surface of an ultrapure cooling water system in a Hungarian power plant and was characterized by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain P2T was affiliated with the family ‘Flexibacteraceae’ in the phylum Bacteroidetes. Its closest relative was Flectobacillus lacus CL-GP79T (88.7 % 16S rRNA gene sequence similarity) followed by Arcicella rosea TW5T (86.5 %), Arcicella aquatica NO-502T (86.4 %), Flectobacillus roseus GFA-11T (86.3 %) and Flectobacillus major DSM 103T (85.4 %). Cells of strain P2T were facultatively anaerobic, non-motile rods. The major fatty acids were C16 : 1 ω5c (42.5 %), iso-C15 : 0 2-OH (17.2 %), iso-C17 : 0 3-OH (16.1 %) and iso-C15 : 0 (8.5 %). The major menaquinone was MK-7 and the predominant polar lipid was phosphatidylethanolamine. The DNA G+C content was 54.5 mol%. Thus, the phenotypic and genotypic analyses clearly showed that strain P2T is considerably different from members of other genera in the family ‘Flexibacteraceae’. Based on these results, it is concluded that strain P2T represents a novel species in a new genus, for which the name Siphonobacter aquaeclarae gen. nov., sp. nov. is proposed, with type strain P2T (=DSM 21668T =NCAIM B 02328T).
