A Gram-negative, motile, rod-shaped, Idiomarina-like bacterial strain, ISL-52T, was isolated from a marine solar saltern of the Yellow Sea in Korea and was subjected to a polyphasic taxonomic investigation. Strain ISL-52T grew optimally at pH 7.0–8.0 and at 30–37 °C. It contained Q-8 as the predominant ubiquinone. The major fatty acids (>10 % of total fatty acids) were iso-C15 : 0, iso-C17 : 0 and iso-C17 : 1 ω9c. The DNA G+C content was 53.9 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-52T fell within the genus Idiomarina, joining the type strain of Idiomarina homiensis at a bootstrap resampling value of 100 %. Strain ISL-52T exhibited 16S rRNA gene sequence similarity values of 94.9–96.7 % with respect to the type strains of eight recognized Idiomarina species. The differential phenotypic properties of ISL-52T, together with its phylogenetic distinctiveness, demonstrated that this strain is distinguishable from the recognized Idiomarina species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain ISL-52T represents a novel species of the genus Idiomarina, for which the name Idiomarina salinarum sp. nov. is proposed. The type strain is ISL-52T (=KCTC 12971T=CCUG 54359T).

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).

Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SF-57T formed a coherent cluster with Marinibacillus marinus, with a bootstrap resampling value of 100 %. The level of 16S rRNA gene sequence similarity between strain SF-57T and M. marinus DSM 1297T was 98·9 %. The mean DNA–DNA relatedness level between strain SF-57T and the type strain of M. marinus was 20·6 %. Based on phenotypic properties, phylogenetic analyses and genomic data, strain SF-57T merits placement in the genus Marinibacillus as a representative of a novel species, for which the name Marinibacillus campisalis sp. nov. is proposed.

A Gram-variable, motile and rod-shaped bacterial strain, ASL-1T, was isolated from a marine saltern located on the coast of the Yellow Sea, Korea. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain ASL-1T clustered with Jeotgalibacillus alimentarius YKJ-13T and that this cluster joined the clade comprising the type strains of two Marinibacillus species. Strain ASL-1T exhibited 16S rRNA gene sequence similarity values of 97.3 % to J. alimentarius YKJ-13T and 96.5 % to the type strains of Marinibacillus marinus and Marinibacillus campisalis. The chemotaxonomic properties of strain ASL-1T were similar to those of one or two of the genera Jeotgalibacillus and Marinibacillus. The peptidoglycan type was A1α linked directly through l-lysine as the diamino acid. Strain ASL-1T contained MK-7 as the predominant menaquinone with the presence of a significant amount of MK-8. The predominant fatty acid was anteiso-C15 : 0. The DNA G+C content was 42.9 mol%. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain ASL-1T could be differentiated from J. alimentarius and the two Marinibacillus species. On the basis of the data presented, strain ASL-1T represents a novel species within the genus Jeotgalibacillus, for which the name Jeotgalibacillus salarius sp. nov. is proposed. The type strain is ASL-1T (=KCTC 13257T=CCUG 56751T). It is also proposed that Marinibacillus marinus and Marinibacillus campisalis be reclassified as Jeotgalibacillus marinus comb. nov. (type strain 581T=DSM 1297T=ATCC 29841T=CCUG 28884T=CIP 103308T=LMG 6930T) and Jeotgalibacillus campisalis comb. nov. (type strain SF-57T=KCCM 41644T=JCM 11810T), respectively.

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 Gram-negative, non-spore-forming, yellow-pigmented, slightly halophilic bacterial strain, SW-109T, was isolated from a tidal flat of the Yellow Sea in Korea, and subjected to a polyphasic taxonomic study. This isolate did not produce bacteriochlorophyll a and contained ubiquinone-10 as the predominant respiratory lipoquinone and C18 : 1 ω7c as the major fatty acid. The DNA G+C content was 60·3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SW-109T is phylogenetically affiliated to the genus Erythrobacter of the family Sphingomonadaceae. Strain SW-109T exhibited levels of 16S rRNA gene sequence similarity to the type strains of Erythrobacter species of 94·0–96·3 %, making it possible to categorize strain SW-109T as a species that is separate from previously recognized Erythrobacter species. On the basis of its phenotypic properties and phylogenetic distinctiveness, SW-109T (=KCTC 12311T=JCM 12599T) was classified as the type strain of a novel Erythrobacter species, for which the name Erythrobacter luteolus sp. nov. is proposed.

A Gram-negative-staining, non-motile and rod-shaped bacterial strain, HD-28T, was isolated from a tidal flat of the Yellow Sea, Korea. Strain HD-28T grew optimally at pH 7.0–8.0 and 30 °C in the presence of 2–3 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HD-28T was most closely related to species of the genus Ruegeria and exhibited 95.5–96.9 % 16S rRNA gene sequence similarity to the type strains of Ruegeria species. A neighbour-joining phylogenetic tree based on gyrB gene sequences also showed that strain HD-28T fell within the cluster comprising recognized species of the genus Ruegeria, showing 77.5–83.9 % sequence similarity. Strain HD-28T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids detected in strain HD-28T were phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid and two unidentified lipids. The DNA G+C content was 57.9 mol%. Differential phenotypic properties, together with phylogenetic distinctiveness, demonstrated that strain HD-28T could be distinguished from recognized species of the genus Ruegeria. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain HD-28T is considered to represent a novel species of the genus Ruegeria, for which the name Ruegeria faecimaris sp. nov. is proposed. The type strain is HD-28T ( = KCTC 23044T = CCUG 58878T).
