A Gram-positive, slightly halophilic, rod-shaped bacterium, designated CL-DD14T, was isolated from seawater of the East Sea, Korea. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain CL-DD14T belongs to the genus Nocardioides. Levels of 16S rRNA gene sequence similarity between strain CL-DD14T and the type strains of recognized species of the genus Nocardioides were low (94.1–97.1 %). Strain CL-DD14 T grew over the pH range 6–9 and temperature range 10–40 °C. The strain grew at NaCl concentrations of 0.5–8 % (w/v) with optimum growth at 1–3 % and no growth was observed after 3 weeks on nutrient agar without any salts. It contained ll-diaminopimelic acid as the diamino acid in the cell wall. The major isoprenoid quinone was MK-8(H4) and the major cellular fatty acids were iso-C16 : 0 and 10-methyl C17 : 0. The DNA G+C content was 72.9 mol%. On the basis of phenotypic and phylogenetic data, strain CL-DD14T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides marinus sp. nov. is proposed. The type strain is CL-DD14T (=KCCM 42321T=DSM 18248T).

A Gram-positive, non-motile, spherical, non-spore-forming bacterial strain, DS-52T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. It grew optimally at 25 °C and pH 6.0–7.0. Strain DS-52T had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and galactose, mannose, xylose and rhamnose as whole-cell sugars. It contained MK-8(H4) and MK-9(H4) as the predominant menaquinones and anteiso-C15 : 0, iso-C15 : 0 and C17 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyldimethylethanolamine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-52T is most closely related to the genus Nakamurella of the suborder Frankineae. Strain DS-52T exhibited 16S rRNA gene sequence similarity values of 96.5 % to Nakamurella multipartita JCM 9543T and 92.0–93.9 % to other members of the suborder Frankineae. The diagnostic diamino acid type and polar lipid profile of strain DS-52T were the same as those of the genus Nakamurella. However, strain DS-52T could be clearly distinguished from the genus Nakamurella by differences in predominant menaquinones, major fatty acids and cell-wall sugars. Accordingly, based on combined phenotypic, chemotaxonomic and phylogenetic data, strain DS-52T (=KCTC 19127T=CIP 108919T) is proposed as the type strain of a novel species in a new genus, Humicoccus flavidus gen. nov., sp. nov.

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.
