A Gram-positive, rod- or coccoid-shaped bacterial strain, DS-17T, was isolated from a soil in Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain DS-17T grew optimally at around pH 8.0 and 30 °C in the presence of 0.5–1.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-17T belonged to the genus Nocardioides. The chemotaxonomic properties of strain DS-17T were consistent with those of the genus Nocardioides: the cell-wall peptidoglycan type was based on ll-2,6-diaminopimelic acid, MK-8(H4) was the predominant menaquinone and iso-C16 : 0, C17 : 1 ω8c and C17 : 0 were the major fatty acids. The DNA G+C content was 71.5 mol%. Strain DS-17T exhibited 16S rRNA gene sequence similarity values of 94.5–96.9 % to the type strains of recognized Nocardioides species. Strain DS-17T could be distinguished from recognized Nocardioides species by differences in phenotypic characteristics. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DS-17T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides terrigena sp. nov. is proposed. The type strain is DS-17T (=KCTC 19217T=JCM 14582T).

A Gram-stain-negative, non-motile, non-spore-forming bacterial strain, BDR-9T, was isolated from soil collected from Boryung on the west coast of the Korean peninsula, and its taxonomic position was investigated by using a polyphasic study. Strain BDR-9T grew optimally at 25 °C, at pH 6.0–7.5 and in the absence of NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain BDR-9T fell within the clade comprising species of the genus Mucilaginibacter within the phylum Bacteroidetes. 16S rRNA gene sequence similarity values between strain BDR-9T and the type strains of species of the genus Mucilaginibacter were in the range 94.0–95.6 %. Strain BDR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and C16 : 1ω7c and/or iso-C15 : 0 2-OH as the major fatty acids. The DNA G+C content was 44.3 mol%. Differential phenotypic properties and phylogenetic distinctiveness of strain BDR-9T demonstrated that this strain is distinguishable from species of the genus Mucilaginibacter. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain BDR-9T is considered to represent a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter boryungensis sp. nov. is proposed.

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).
