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 Gram-strain-negative, coccoid or oval-shaped, non-motile bacterial strain, designated MDM-1T, was isolated from a tidal-flat sediment on the Korean peninsula. Strain MDM-1T was found to grow optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain MDM-1T falls within the clade comprising species of the genus Algoriphagus, clustering with the type strains of Algoriphagus halophilus, A. lutimaris, A. chungangensis and A. machipongonensis, with which it exhibited 97.2–98.5 % 16S rRNA gene sequence similarity. Sequence similarities to the type strains of the other recognized species of the genus Algoriphagus were 92.8–97.6 %. Strain MDM-1T was found to contain MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) as the major fatty acids. The major polar lipids were identified as phosphatidylcholine, phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain MDM-1T was determined to be 42.7 mol% and the mean DNA–DNA relatedness with A. halophilus KCTC 12051T, A. lutimaris S1-3T, A. chungangensis KCTC 23759T, A. machipongonensis DSM 24695T and A. ratkowskyi CIP 107452T was 19.7–5.2 %. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain MDM-1T is distinguishable from recognized species of the genus Algoriphagus. On the basis of the data presented, strain MDM-1T is proposed to represent a novel species of the genus Algoriphagus, for which the name Algoriphagus aestuarii sp. nov. is proposed. The type strain is MDM-1T ( = KCTC 42199T = NBRC 110552T).
