A marine actinomycete strain, designated KSW2-15T, was isolated from a dried seaweed sample collected from a sandy beach on the coast of Jeju in the Republic of Korea. The organism produced non-motile, non-endospore-forming, Gram-positive, coccoid cells. The colonies were circular, translucent and yellow in colour with entire margins. meso-Diaminopimelic acid was present as the diamino acid of the peptidoglycan. The acyl type of the muramic acid was acetyl. Mycolic acids were not present. The predominant menaquinone was MK-8(H4). The polar lipids were phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were of the saturated, unsaturated and iso-branched methyl types. The DNA G+C content was 74 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain KSW2-15T formed a loose association with ‘Candidatus Nostocoida limicola’, within the radiation of the family Intrasporangiaceae of the suborder Micrococcineae. The organism showed the highest levels of sequence similarity with ‘Candidatus Nostocoida limicola’ (96.1 %), Terrabacter tumescens (96.1 %) and Terrabacter terrae (96.0 %). The levels of 16S rRNA gene sequence similarity between the isolate and members of other genera of the family Intrasporangiaceae were in the range 92.1–95.5 %. On the basis of the polyphasic evidence, the isolate should be classified within a novel genus and species, for which the name Phycicoccus jejuensis gen. nov., sp. nov. is proposed. The type strain of Phycicoccus jejuensis is strain KSW2-15T (=KCCM 42315T=NRRL B-24460T).

A novel actinomycete strain, designated KLBMP 1356T, was isolated from the root of halophyte Tamarix chinensis Lour. collected from the coastal area of Jiangsu province, PR China. The isolate was characterized using a polyphasic approach. Comparative analysis of the 16S rRNA gene sequence indicated that strain KLBMP 1356T was phylogenetically related to members of the family Pseudonocardiaceae and formed a distinct monophyletic clade between the genera Amycolatopsis (93.1–94.7 % 16S rRNA gene sequence similarity), Prauserella (93.6–95.1 %) and Saccharomonospora (93.2–94.3 %). The isolate displayed long spore chains containing rod-shaped and smooth-surfaced spores. Strain KLBMP 1356T contained meso-diaminopimelic acid as the diagnostic diamino acid, and galactose, arabinose and glucose as the whole-cell sugars. The major menaquinone was MK-9(H4) and the fatty acid profile was characterized by the predominance of iso-C16 : 0, C17 : 1ω8c, C17 : 1ω6c and C17 : 0. The polar lipids comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, unknown aminophospholipids and an unknown glycolipid. Mycolic acids were not present. The G+C content of the genomic DNA was 67.2 mol%. On the basis of the evidence from this polyphasic study, strain KLBMP 1356T is considered to represent a novel species of a new genus in the family Pseudonocardiaceae, for which the name Tamaricihabitans halophyticus gen. nov., sp. nov. is proposed. The type strain of the type species is KLBMP 1356T ( = DSM 45765T = NBRC 109361T).

A Gram-staining-negative, non-flagellated, non-gliding and pleomorphic bacterial strain, designated DPG-25T, was isolated from seawater in a seaweed farm in the South Sea in Korea and its taxonomic position was investigated by using a polyphasic approach. Strain DPG-25T grew optimally at 25 °C, at pH 7.0–7.5 and in the presence of 2 % (w/v) NaCl. Flexirubin-type pigments were not produced. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DPG-25T formed a cluster with the type strains of Actibacter sediminis , Aestuariicola saemankumensis and Lutimonas vermicola . Strain DPG-25T exhibited 16S rRNA gene sequence similarity values of 95.3, 93.1 and 93.6 % to the type strains of Actibacter sediminis , Aestuariicola saemankumensis and L. vermicola , respectively. Strain DPG-25T contained MK-6 as the predominant menaquinone and iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain DPG-25T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content was 39.9 mol%. Differential phenotypic properties and the phylogenetic distinctiveness of strain DPG-25T demonstrated that this strain is distinguishable from Actibacter sediminis , Aestuariicola saemankumensis and L. vermicola . On the basis of the data presented here, strain DPG-25T represents a novel species in a novel genus of the family Flavobacteriaceae , for which the name Namhaeicola litoreus gen. nov., sp. nov. is proposed. The type strain of Namhaeicola litoreus is DPG-25T ( = KCTC 23702T  = CCUG 61485T).

A Gram-positive, non-motile, rod-shaped actinomycete strain, designated SSW1-57T, was isolated from a dried seaweed sample from the coast of Jeju Island, Republic of Korea and subjected to a polyphasic taxonomic study. A neighbour-joining tree based on 16S rRNA gene sequences showed that the organism was related to members of the family Nocardioidaceae and formed a separate branch at the base of a taxon encompassing members of the genus Aeromicrobium, whereas it occupied an intermediate position between Aeromicrobium alkaliterrae–Aeromicrobium marinum and Aeromicrobium erythreum–Aeromicrobium fastidiosum clusters in maximum-parsimony and maximum-likelihood trees. The phylogenetic association of the isolate with the genus Aeromicrobium was supported by the following chemotaxonomic properties: ll-diaminopimelic acid in the peptidoglycan, MK-9(H4) as the major menaquinone and major fatty acids cis-9-octadecenoic acid, hexadecanoic acid, 10-methyl octadecanoic acid and 2-hydroxy hexadecanoic acid. The polar lipid profile contained phosphatidylinositol, diphosphatidylglycerol and phosphatidylglycerol. Levels of 16S rRNA gene sequence similarity between the novel organism and the type strains of the four recognized Aeromicrobium species were in the range 96.5–96.7 %. On the basis of phylogenetic analyses and phenotypic data, it is proposed that the organism should be classified as representing a novel species of the genus Aeromicrobium, with the name Aeromicrobium tamlense sp. nov. The type strain is SSW1-57T (=JCM 13811T=NRRL B-24466T).

A Gram-positive, non-motile and rod- or coccoid-shaped bacterial strain, MDN22T, was isolated from a soil sample from Korea. Strain MDN22T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 0–0.5 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain MDN22T was phylogenetically most closely related to the genera Nocardioides and Marmoricola. In the neighbour-joining phylogenetic tree, strain MDN22T was most closely related to Nocardioides jensenii KCTC 9134T, with which it exhibited 98.3 % 16S rRNA gene sequence similarity. The strain exhibited 93.1–96.9 % and 95.3–95.9 % 16S rRNA gene sequence similarities to the type strains of other species of the genera Nocardioides and Marmoricola, respectively. The chemotaxonomic properties of strain MDN22T were consistent with those of the genus Nocardioides; the cell-wall peptidoglycan type was based on ll-2,6-diaminopimelic acid, the predominant menaquinone was MK-8(H4) and the major fatty acids were iso-C16 : 0 and C17 : 1. The DNA G+C content was 68.7 mol%. DNA–DNA relatedness data and differential phenotypic properties suggested that strain MDN22T could be differentiated from N. jensenii and Nocardioides dubius. On the basis of the data obtained, strain MDN22T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides daedukensis sp. nov., is proposed. The type strain is MDN22T (=KCTC 19601T=CCUG 57505T).
