A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated W-WS13T, was isolated from wood falls collected around Wando, an island in the South Sea of South Korea, and subjected to a polyphasic taxonomic study. Strain W-WS13T grew optimally at 30 °C, at pH 7.5 and in the presence of 0.5 % NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain W-WS13T belonged to the genus Pedobacter, clustering robustly with the type strain of Pedobacter arcticus, sharing 95.9 % sequence similarity. Strain W-WS13T exhibited 16S rRNA gene sequence similarity of 90.1–95.6 % to the type strains of the other species of the genus Pedobacter. Strain W-WS13T contained MK-7 as the predominant menaquinone and iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipid detected in strain W-WS13T was phosphatidylethanolamine. The DNA G+C content of strain W-WS13T was 36.9 mol%. Phylogenetic distinctiveness and differential phenotypic properties of strain W-WS13T revealed that the novel strain is separated from recognized species of the genus Pedobacter. On the basis of the data presented, strain W-WS13T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter lignilitoris 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.
