A Gram-positive, endospore-forming bacterium, designated strain BT080T, was isolated from a soil sample in Jeju, Korea. Cells of the isolate were strictly aerobic rods that were motile by means of peritrichous flagella. The strain grew optimally at 30–33 °C and pH 5.5–6.5. Chemotaxonomic data (major isoprenoid quinone, MK-7; DNA G+C content, 43.3 mol%; major fatty acids, anteiso-C15 : 0, iso-C14 : 0, iso-C16 : 0 and iso-C15 : 0) supported the affiliation of the isolate to the genus Bacillus. Comparative 16S rRNA gene sequence analyses showed that strain BT080T formed a distinct phyletic line within the genus Bacillus. The levels of 16S rRNA gene sequence similarity with respect to related Bacillus species were below 96.4 %. On the basis of physiological, biochemical and phylogenetic properties, strain BT080T represents a novel species within the genus Bacillus, for which the name Bacillus kribbensis sp. nov. is proposed. The type strain is BT080T (=KCTC 13934T=DSM 17871T).

A Gram-staining-negative, yellow-coloured, strictly aerobic, non-spore-forming, rod-shaped bacterium, designated HS39T, isolated from a soil sample collected from a natural Populus euphratica forest in Xinjiang, China, was characterized using a polyphasic approach. The isolate grew optimally at 30–37 °C, at pH 6.5–8.0 and with 0–3 % NaCl. Analysis of the 16S rRNA gene sequence of strain HS39T revealed that it is a member of the genus Sphingobacterium. Sphingobacterium mizutaii ATCC 33299T was the nearest relative (94.0 % 16S rRNA gene sequence similarity). The G+C content of the genomic DNA was 40.2 mol%. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1 ω6c and/or C16 : 1 ω7c). The predominant isoprenoid quinone was MK-7. On the basis of phenotypic properties and phylogenetic inference, strain HS39T represents a novel species of the genus Sphingobacterium, for which the name Sphingobacterium shayense sp. nov. is proposed. The type strain is HS39T (=CCTCC AB 209006T =NRRL B-59203T).

A Gram-negative, strictly aerobic bacterium, designated CL-ES53T, was isolated from surface water of the East Sea in Korea. Cells of strain CL-ES53T were short rods and motile by means of monopolar flagella. Strain CL-ES53T grew with 4–21 % NaCl (optimum 10 %) and at 5–40 °C (optimum 25 °C) and pH 5.2–8.8 (optimum pH 6.3–7.2). The major isoprenoid quinone was Q-8. The major fatty acids were C18 : 1 ω7c (42.0 %), C18 : 1 ω9c (14.8 %) and C14 : 0 (9.4 %). The genomic DNA G+C content was 64.9 mol%. Analysis of the 16S rRNA gene sequence of strain CL-ES53T revealed that it was a member of the genus Salinisphaera and most closely related to Salinisphaera shabanensis E1L3A T (96.9 % sequence similarity) and Salinisphaera hydrothermalis EPR70T (93.8 %). Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain CL-ES53T formed a robust cluster with S. shabanensis E1L3A T. Although the 16S rRNA gene sequence similarity between strain CL-ES53T and S. shabanensis E1L3A T was rather high (96.9 %), DNA–DNA relatedness between these strains was 12 %, suggesting that they represent genomically distinct species. Strain CL-ES53T was differentiated from S. shabanensis E1L3A T and S. hydrothermalis EPR70T on the basis of optimum temperature for growth and certain phenotypic characteristics. The phylogenetic analysis and physiological and chemotaxonomic data show that strain CL-ES53T should be classified in the genus Salinisphaera within a novel species, for which the name Salinisphaera dokdonensis sp. nov. is proposed. The type strain is CL-ES53T (=KCCM 90064T =DSM 19549T).

A novel myxobacterium, MCy1366T (Ar1733), was isolated in 1981 from a soil sample collected from a region near Tokyo, Japan. It displayed general myxobacterial features like Gram-negative-staining, rod-shaped vegetative cells, gliding on solid surfaces, microbial lytic activity, fruiting-body-like aggregates and myxospore-like structures. The strain was mesophilic, aerobic and showed a chemoheterotrophic mode of nutrition. It was resistant to many antibiotics such as cephalosporin C, kanamycin, gentamicin, hygromycin B, polymyxin and bacitracin, and the key fatty acids of whole cell hydrolysates were iso-C15 : 0, iso-C17 : 0 and iso-C17 : 0 2-OH. The genomic DNA G+C content of the novel strain was 65.6 mol%. The 16S rRNA gene sequence showed highest similarity (97.60 %) to ‘Stigmatella koreensis’ strain KYC-1019 (GenBank accession no. EF112185). Phylogenetic analysis based on 16S rRNA gene sequences and MALDI-TOF MS data revealed a novel branch in the family Myxococcaceae . DNA–DNA hybridization showed only 28 % relatedness between the novel strain and the closest recognized species, Corallococcus exiguus DSM 14696T (97 % 16S rRNA gene sequence similarity). A recent isolate from a soil sample collected in Switzerland, MCy10622, displayed 99.9 % 16S rRNA gene sequence similarity with strain MCy1366T and showed almost the same characteristics. Since some morphological features like fruiting-body-like aggregates were barely reproducible in the type strain, the newly isolated strain, MCy10622, was also intensively studied. On the basis of a comprehensive taxonomic study, we propose a novel genus and species, Aggregicoccus edonensis gen. nov., sp. nov., for strains MCy1366T and MCy10622. The type strain of the type species is MCy1366T ( = DSM 27872T = NCCB 100468T).

Five strains of strictly aerobic, heterotrophic bacteria that form pink–red colonies and are capable of hydrolysing pectin, xylan, laminarin, lichenan and starch were isolated from acidic Sphagnum peat bogs and were designated OB1010T, LCBR1, TPB6011T, TPB6028T and TPO1014T. Cells of these isolates were Gram-negative, non-motile rods that produced an amorphous extracellular polysaccharide-like substance. Old cultures contained spherical bodies of varying sizes, which represent starvation forms. Cells of all five strains were acidophilic and psychrotolerant, capable of growth at pH 3.0–7.5 (optimum pH 3.8–4.5) and at 2–33 °C (optimum 15–22 °C). The major fatty acids were iso-C15 : 0, C16 : 0 and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH). The major menaquinone detected was MK-8. The pigments were carotenoids. The genomic DNA G+C contents were 57.3–59.3 mol%. The five isolates were found to be members of subdivision 1 of the phylum Acidobacteria and displayed 95.3–98.9 % 16S rRNA gene sequence similarity to each other. The closest described relatives to strains OB1010T, LCBR1, TPB6011T, TPB6028T, and TPO1014T were members of the genera Terriglobus (94.6–95.8 % 16S rRNA gene sequence similarity) and Edaphobacter (94.2–95.4 %). Based on differences in cell morphology, phenotypic characteristics and hydrolytic capabilities, we propose a novel genus, Granulicella gen. nov., containing four novel species, Granulicella paludicola sp. nov. with type strain OB1010T (=DSM 22464T =LMG 25275T) and strain LCBR1, Granulicella pectinivorans sp. nov. with type strain TPB6011T (=VKM B-2509T =DSM 21001T), Granulicella rosea sp. nov. with type strain TPO1014T (=DSM 18704T =ATCC BAA-1396T) and Granulicella aggregans sp. nov. with type strain TPB6028T (=LMG 25274T =VKM B-2571T).

A Gram-stain-negative, yellow-pigmented, rod-shaped, strictly aerobic, non-flagellated, non-gliding and oxidase- and catalase-positive bacterium, designated A6T, was isolated from a marine sponge, Halichondria oshoro, collected on the coast of Jeju Island, South Korea. Phylogenetic analysis based on the nearly complete 16S rRNA gene sequence revealed that strain A6T was a member of the family Flavobacteriaceae. The closest relatives were Aquimarina intermedia LMG 23204T, A. latercula ATCC 23177T, A. brevivitae SMK-19T and A. muelleri KMM 6020T, with which strain A6T shared 95.7, 95.1, 94.7 and 94.6 % 16S rRNA gene sequence similarity, respectively. The dominant fatty acids of strain A6T were iso-C15 : 0 (32.2 %), iso-C17 : 0 3-OH (20.0 %), iso-C15 : 0 3-OH (12.3 %), iso-C15 : 1 G (7.2 %) and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1 ω7c; 6.8 %). The DNA G+C content of strain A6T was 36.0 mol% and the major respiratory quinone was MK-6. On the basis of combined phenotypic and phylogenetic analyses, strain A6T represents a novel species of the genus Aquimarina, for which the name Aquimarina spongiae sp. nov. is proposed. The type strain is A6T (=KCTC 22663T =DSM 22623T).

Abstract Strain WRN001T, a Gram–staining–negative, strictly aerobic, non–motile bacterium was isolated from the natural saline-alkali wetland soil of Binhai new district, Tianjin, China (38°46′N, 117°13′E). Cells of strain WRN001T were 0.3-0.5 µm in width and 1.5-2.5 µm in length, and the growth occurred optimally at 33-37 °C, pH 7.5-8.0, and in the presence of 8-10% (w/v) NaCl. Based on 16S rRNA gene sequence analysis, the isolate could be affiliated to the genus Halomonas, and the highest 16S rRNA gene sequence similarity of strain WRN001T to its closest relative Halomonas qiaohouensis YIM QH88T was 97.47%. The size of the genome as presented here was 5,475,884 bp with a G+C content of 63.8 mol %. The major respiratory quinone of strainWRN001T was Q-9, and the dominant fatty acids were summed feature 8, summed feature 3, C10:0, C12:0, C12:0 3-OH, C16:0, and C17:0 cyclo. The major polar lipids were diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phophatidylcholine (PC), two phospholipids (PL), aminolipid (AL), and three unidentified lipids (L). These data mentioned above combined with the low DDH values between strain WRN001T and the close relative, Halomonas alkalitolerans 1513T (42.20%) and base on comparisons with currently available genomes, the highest average nucleotide identity (ANIm) value was 91.39% to Halomonas alkalitolerans 1513T (GenBank accession No. GCA_001971685.1). Therefore, we propose a novel species in the genus Halomonas to accommodate this novel isolate: Halomonas salipaludis sp. nov. (type strain WRN001T = KCTC 52853T = ACCC 19974T).

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated Gsoil 104T, was isolated from a soil sample from a ginseng field in Pocheon Province (South Korea) and was characterized taxonomically by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain Gsoil 104T was shown to belong to the family Sphingobacteriaceae, being related to Pedobacter africanus DSM 12126T (97.0 %), Pedobacter caeni LMG 22862T (96.9 %), Pedobacter cryoconitis DSM 14825T (96.8 %) and Pedobacter heparinus DSM 2366T (96.6 %). The phylogenetic distance from any other Pedobacter species with a validly published name was greater than 3.4 % (i.e. <96.6 % 16S rRNA gene sequence similarity). DNA–DNA hybridization experiments showed that values for DNA–DNA relatedness between strain Gsoil 104T and its phylogenetically closest neighbours were below 37 %. The G+C content of the genomic DNA was 43.6 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were C16 : 1 ω7c, iso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH and iso-C15 : 0 2-OH. These chemotaxonomic data support the affiliation of strain Gsoil 104T to the genus Pedobacter. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 104T represents a novel species in the genus Pedobacter, for which the name Pedobacter ginsengisoli sp. nov. is proposed. The type strain is Gsoil 104T (=KCTC 12576T=LMG 23399T).

A Gram-positive, non-motile, endospore-forming bacterial strain, designated Gsoil 420T, was isolated from soil of a ginseng field in Pocheon Province, South Korea, and was characterized, using a polyphasic approach, in order to determine its taxonomic position. The novel isolate consisted of strictly aerobic, rod-shaped cells and was able to grow in medium supplemented with up to 12 % NaCl at 25 °C and pH 6.5–7.0. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 420T fell within the radiation of the cluster comprising Bacillus species and formed a coherent cluster with Bacillus niacini (16S rRNA gene sequence similarity, 98.6 %), Bacillus bataviensis (98.6 %), Bacillus soli (98.3 %), Bacillus drentensis (98.0 %), Bacillus novalis (98.0 %), Bacillus vireti (97.9 %), Bacillus foraminis (97.6 %), Bacillus fumarioli (97.4 %) and Bacillus jeotgali (97.0 %). The levels of 16S rRNA gene sequence similarity with respect to other Bacillus species with validly published names were less than 96.8 %. Strain Gsoil 420T had a genomic DNA G+C content of 44.9 mol% and the predominant respiratory quinone was MK-7. The major fatty acids were anteiso-C15 : 0 (33.9 %), iso-C15 : 0 (24.5 %) and iso-C14 : 0 (19.9 %). These chemotaxonomic results supported the affiliation of strain Gsoil 420T to the genus Bacillus. However, low DNA–DNA relatedness values and distinguishing phenotypic characteristics allowed genotypic and phenotypic differentiation of strain Gsoil 420T from recognized Bacillus species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 420T represents a novel species of the genus Bacillus, for which the name Bacillus pocheonensis sp. nov. is proposed. The type strain is Gsoil 420T (=KCTC 13943T=DSM 18135T).

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).
