A Gram-stain-negative, aerobic, motile, rod-shaped bacterial strain, GSW-M6T, was isolated from seawater of Geoje island, Korea, and was subjected to a polyphasic taxonomic study. Strain GSW-M6T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain GSW-M6T clustered with Thalassobius aestuarii, Thalassobius gelatinovorus and Thalassobius mediterraneus. Strain GSW-M6T exhibited 96.2–96.9 % 16S rRNA gene sequence similarity to the type strains of these three Thalassobius species. Strain GSW-M6T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profiles of strain GSW-M6T and the type strains of the three Thalassobius species were similar, with phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified lipid as common major components. The DNA G+C content of strain GSW-M6T was 57 mol%. The mean level of DNA–DNA relatedness between strain GSW-M6T and the type strain of Thalassobius gelatinovorus was 17 %. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, enabled strain GSW-M6T to be differentiated from recognized species of the genus Thalassobius. On the basis of the data presented, strain GSW-M6T is considered to represent a novel species of the genus Thalassobius, for which the name Thalassobius maritimus sp. nov. is proposed. The type strain is GSW-M6T ( = KCTC 23347T  = CCUG 60021T).

ABSTRACT A Gram-stain-negative bacterial strain, JBTF-M27T, was isolated from a tidal flat from Yellow Sea, Republic of Korea. Neighbor-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M27T fell within the clade comprising the type strains of Sulfitobacter species. Strain JBTF-M27T exhibited the highest 16S rRNA gene sequence similarity (98.8%) to the type strain of S. porphyrae. Genomic ANI and dDDH values of strain JBTF-M27T between the type strains of Sulfitobacter species were less than 76.1 and 19.2%, respectively. Mean DNA-DNA relatedness value between strain JBTF-M27T and the type strain of S. porphyrae was 21%. DNA G + C content of strain JBTF-M27T from genome sequence was 57.8% (genomic analysis). Strain JBTF-M27T contained Q-10 as the predominant ubiquinone and C18:1ω7c as the major fatty acid. The major polar lipids of strain JBTF-M27T were phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M27T is separated from recognized Sulfitobacter species. On the basis of the data presented, strain JBTF-M27T ( = KACC 21648T = NBRC 114356T) is considered to represent a novel species of the genus Sulfitobacter, for which the name Sulfitobacter sediminilitoris 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.
