A Gram-staining-variable, motile, endospore-forming and rod-shaped bacterial strain, IDS-20T, was isolated from a marine solar saltern in Korea and subjected to a polyphasic taxonomic investigation. Strain IDS-20T grew optimally at 37 °C, at pH 7.5–8.0 and in the presence of 4–5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain IDS-20T belongs to the genus Virgibacillus. Strain IDS-20T exhibited 93.4–96.6 % 16S rRNA gene sequence similarity to the type strains of species of the genus Virgibacillus. Strain IDS-20T had MK-7 as the predominant menaquinone and a cell-wall peptidoglycan based on meso-diaminopimelic acid. The major fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0 and major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and two unidentified phospholipids. The DNA G+C content was 39.5 mol%. The phylogenetic distinctiveness and differential phenotypic characteristics of strain IDS-20T demonstrated that this strain can be distinguished from recognized species of the genus Virgibacillus. On the basis of the data presented, strain IDS-20T represents a novel species of the genus Virgibacillus, for which the name Virgibacillus campisalis sp. nov. is proposed. The type strain is IDS-20T ( = KCTC 13727T  = CCUG 59308T).

A Gram-stain-variable, motile, moderately halophilic bacterial strain, CHL-21T, was isolated from a marine solar saltern and its taxonomic position was investigated using a polyphasic approach. Optimal growth of strain CHL-21T occurred at 30–37 °C, at pH 7.0–7.5 and in the presence of 5–10 % (w/v) NaCl. In phylogenetic trees based on 16S rRNA gene sequences, strain CHL-21T fell within the cluster comprising members of the genera Oceanobacillus, Ornithinibacillus and Paucisalibacillus. Strain CHL-21T exhibited 97.1–97.2 % 16S rRNA gene sequence similarity to the type strains of the two subspecies of Oceanobacillus oncorhynchi and 92.0–94.7 % 16S rRNA gene sequence similarity to the type strains of other members of the genus Oceanobacillus and members of the genera Ornithinibacillus and Paucisalibacillus. Mean DNA–DNA reassociation values between strain CHL-21T and the type strains of the two subspecies of Oceanobacillus oncorhynchi were 19–21 %. The cell-wall peptidoglycan of strain CHL-21T was based on meso-diaminopimelic acid, MK-7 was the predominant menaquinone, and anteiso-C15 : 0 and anteiso-C17 : 0 were the major fatty acids. The DNA G+C content was 39.8 mol%. Differential phenotypic properties, including facultatively anaerobic growth and acid production from substrates, together with its phylogenetic and genetic distinctiveness, demonstrated that strain CHL-21T is distinguishable from recognized Oceanobacillus species. On the basis of data presented, strain CHL-21T represents a novel species within the genus Oceanobacillus, for which the name Oceanobacillus locisalsi sp. nov. is proposed; the type strain is CHL-21T (=KCTC 13253T =CCUG 56608T).

A Gram-negative, non-motile, rod-shaped bacterium, strain ISL-6T, phenotypically resembling members of the genus Salegentibacter, was isolated from a marine solar saltern of the Yellow Sea in Korea and subjected to a polyphasic taxonomic investigation. Strain ISL-6T grew optimally at pH 7.0–8.0 and 30 °C and in the presence of 8 % (w/v) NaCl. It contained MK-6 as the predominant menaquinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The DNA G+C content was 37.5 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-6T belonged to the genus Salegentibacter. Strain ISL-6T exhibited 16S rRNA gene sequence similarity values of 92.0–98.6 % with respect to the type strains of recognized Salegentibacter species. Low DNA–DNA relatedness values, differential phenotypic properties and phylogenetic distinctiveness demonstrated that strain ISL-6T is distinguishable from the recognized Salegentibacter species. Therefore strain ISL-6T represents a novel species of the genus Salegentibacter, for which the name Salegentibacter salarius sp. nov. is proposed. The type strain is ISL-6T (=KCTC 12974T =CCUG 54355T).

A Gram-positive or Gram-variable, motile, endospore-forming, halophilic bacterial strain, MSS-402T, was isolated from a marine solar saltern in Korea, and subjected to a polyphasic taxonomic study. Some cells of strain MSS-402T were long filamentous rods. The isolate grew optimally at 37 °C and in the presence of 3–5 % (w/v) NaCl. Strain MSS-402T had cell-wall peptidoglycan based on l-orn–d-Asp, MK-7 as the predominant menaquinone and anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as major fatty acids. The DNA G+C content was 42·9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain MSS-402T falls within the evolutionary radiation of species of the genus Halobacillus. Levels of 16S rRNA gene sequence similarity between strain MSS-402T and the type strains of recognized Halobacillus species ranged from 98·0 % (with Halobacillus halophilus) to 99·2 % (with Halobacillus litoralis and Halobacillus trueperi). Levels of DNA–DNA binding indicated that strain MSS-402T represents a genomic species that is distinct from recognized Halobacillus species. Strain MSS-402T was differentiated from Halobacillus species by means of several phenotypic characteristics. On the basis of its phenotypic properties and phylogenetic and genetic distinctiveness, strain MSS-402T (=KCTC 3957T=DSM 17110T) should be classified as the type strain of a novel Halobacillus species, for which the name Halobacillus yeomjeoni sp. nov. is proposed.

A moderately halophilic, aerobic, Gram-negative bacterium was isolated from a tidal flat area of Dae-Chun, Chung-Nam, Korea. The strain, designated mano11T, comprised rod-shaped cells that were motile by means of polar flagella. It grew with 3–12 % NaCl and at 4–37 °C and pH 5.3–9.3. The predominant menaquinone present in this strain was MK-7 and diaminopimelic acid was not found in the cell-wall peptidoglycan. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain mano11T belongs to the genus Marinobacterium. Strain mano11T exhibited 92.8–98.3 % 16S rRNA gene sequence similarity when compared with the type strains of three other species of the genus Marinobacterium. DNA–DNA hybridization between strain mano11T and Marinobacterium georgiense DSM 11526T, its closest relative in terms of 16S rRNA gene sequence similarity, was 13 %. On the basis of the phenotypic, genetic and phylogenetic data, strain mano11T represents a novel species of the genus Marinobacterium, for which the name Marinobacterium halophilum sp. nov. is proposed. The type strain is mano11T (=KCTC 12240T=DSM 17586T).

A Gram-staining-negative, aerobic, rod-shaped, non-spore-forming bacterial strain, Ca-34T, was isolated from nodules of chickpea (Cicer arietinum) in Pakistan and studied for its taxonomic affiliation. The almost full-length 16S rRNA gene sequence showed highest similarities to those of strains of the genus Ochrobactrum. Based on results of MALDI-TOF MS and 16S rRNA gene sequence similarity (98.6 %), strain Ca-34T and Ochrobactrum intermedium LMG 3301T are phylogenetic neighbours; the two strains shared DNA–DNA relatedness of 64 %. The fatty acid profile [predominantly C18 : 1 ω7c (67.7 %) and C19 : 0 cyclo ω8c (19.6 %)] also supported the genus affiliation. Metabolically, strain Ca-34T differed from other type strains of Ochrobactrum in many reactions and from all type strains in testing positive for gelatin hydrolysis and in testing negative for assimilation of alaninamide and l-threonine. Based on phenotypic and genotypic data, we conclude that strain Ca-34T represents a novel species, for which we propose the name Ochrobactrum ciceri sp. nov. (type strain Ca-34T =DSM 22292T =CCUG 57879T).

A moderately halophilic, Gram-positive, rod-shaped bacterium (BH030004T) was isolated from a solar saltern in Korea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BH030004T belonged to the genus Pontibacillus. Chemotaxonomic data (DNA G+C content, 42 mol%; major isoprenoid quinone, MK-7; cell-wall type, A1γ-type meso-diaminopimelic acid; major fatty acids, iso-C15 : 0 and anteiso-C15 : 0) also supported the affiliation of the isolate to the genus Pontibacillus. Although the 16S rRNA gene sequence similarity between strain BH030004T and Pontibacillus chungwhensis DSM 16287T was relatively high (99·1 %), physiological properties and DNA–DNA hybridization (about 7 % DNA–DNA relatedness) allowed genotypic and phenotypic differentiation of strain BH030004T from the type strain of P. chungwhensis. Therefore, strain BH030004T represents a novel species of the genus Pontibacillus, for which the name Pontibacillus marinus sp. nov. is proposed. The type strain is BH030004T (=KCTC 3917T=DSM 16465T).
