A novel marine bacterium was isolated from a sediment sample from Hwasun Beach in Jeju, Republic of Korea. The cells were found to be Gram-negative, aerobic, oxidase-positive, catalase-positive, motile rods. The organism required natural seawater or artificial sea salts for growth. The temperature and pH ranges for growth were 20–42 °C and pH 5.1–12.1, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the order Rhizobiales and formed a robust cluster with members of the genus Devosia. Its phylogenetic neighbours were the type strains of Devosia riboflavina (96.8 % 16S rRNA gene sequence similarity), Devosia neptuniae (96.7 %), Devosia soli (96.5 %) and Devosia limi (96.2 %), ‘Devosia terrae’ DCY11 (96.2 %) and ‘Candidatus Devosia euplotis’ (96.2 %). The predominant ubiquinone was Q-10, the major fatty acids were C18 : 1, C18 : 0 and C16 : 0 and the G+C content of the DNA was 59.1 mol%. On the basis of phenotypic data and the results of phylogenetic analyses, strain HST3-14T represents a novel species of the genus Devosia, for which the name Devosia subaequoris sp. nov. is proposed. The type strain is strain HST3-14T (=KCTC 12772T =JCM 14206T).

A novel actinomycete, strain KST3-10T, was isolated from sand sediment of a beach in Jeju, Korea, and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, translucent, apricot-coloured colonies comprising coccoid- or rod-shaped cells. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family Geodermatophilaceae and consistently formed a distinct sub-branch outside the radiation of the genus Blastococcus. The organism showed 16S rRNA gene sequence similarity values of 98.2 % with respect to Blastococcus aggregatus DSM 4725T and 98.1 % with respect to Blastococcus saxobsidens BC444T. The type strains of the two Blastococcus species shared 98.2 % sequence similarity with respect to each other, whereas the levels of sequence similarity between the novel organism and the type strains of the less closely related neighbours, Modestobacter multiseptatus and Geodermatophilus obscurus, were in the range 96.2–96.9 %. The physiological, biochemical and chemotaxonomic data revealed that the novel organism can be readily differentiated from members of the genus Blastococcus and that it merits separate species status. On the basis of the phenotypic and genotypic evidence, strain KST3-10T represents a novel species of the genus Blastococcus, for which the name Blastococcus jejuensis sp. nov. is proposed. The type strain is KST3-10T (=NRRL B-24440T=KCCM 42251T).

Two Gram-negative, non-motile, pleomorphic bacterial strains, DS-40T and DS-45T, were isolated from a soil sample collected from Dokdo, Korea, and their exact taxonomic positions were investigated by using a polyphasic approach. Strains DS-40T and DS-45T grew optimally at 25 °C and pH 6.5–7.5 in the presence of 0–1.0 % (w/v) NaCl. They contained MK-7 as the predominant menaquinone and possessed iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C contents of strains DS-40T and DS-45T were 36.0 and 36.8 mol%, respectively. Strains DS-40T and DS-45T shared a 16S rRNA gene sequence similarity of 96.7 % and demonstrated a mean DNA–DNA relatedness level of 12 %. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains DS-40T and DS-45T were most closely phylogenetically affiliated with the genus Pedobacter of the family Sphingobacteriaceae. Strains DS-40T and DS-45T exhibited 16S rRNA gene sequence similarity values of 91.4–93.7 and 89.9–91.6 % with respect to the type strains of Pedobacter and Sphingobacterium species, respectively. Phenotypic and chemotaxonomic properties, together with the phylogenetic data, support the assignment of strains DS-40T and DS-45T as two distinct species within the genus Pedobacter. On the basis of phenotypic, phylogenetic and genetic data, strains DS-40T and DS-45T represent two novel species of the genus Pedobacter, for which the names Pedobacter lentus sp. nov. and Pedobacter terricola sp. nov. are proposed, respectively. The respective type strains are DS-40T (=KCTC 12875T=JCM 14593T) and DS-45T (=KCTC 12876T=JCM 14594T).

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 bacterial strain designated LTC-2T was isolated from a freshwater lake in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain LTC-2T were Gram-reaction-negative, facultatively anaerobic, poly-β-hydroxybutyrate-accumulating, motile by means of a monopolar flagellum, non-spore-forming, slightly curved rods surrounded by a thick capsule and formed creamy white colonies. Growth occurred at 10–37 °C (optimum, 20–30 °C), at pH 6.0–9.0 (optimum, pH 7.0–8.0) and with 0–1.0 % NaCl (optimum, 0 %). The predominant fatty acids were C18 : 1ω7c, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The major isoprenoid quinone was Q-10 and the DNA G+C content was 58.5 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, two uncharacterized phospholipids and two uncharacterized aminophospholipids. The major polyamines were putrescine, homospermidine and spermidine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain LTC-2T forms a distinct lineage with respect to closely related genera in the family Rhodospirillaceae , most closely related to the genera Elstera and Dongia , and the levels of 16S rRNA gene sequence similarity with respect to the type species of related genera were less than 94 %. On the basis of the genotypic and phenotypic data, strain LTC-2T represents a novel genus and species of the family Rhodospirillaceae , for which the name Lacibacterium aquatile gen. nov., sp. nov. is proposed. The type strain is LTC-2T ( = BCRC 80445T = LMG 26999T = KCTC 32017T).

A Gram-variable, endospore-forming moderately halophilic rod, strain SF-121, was isolated from a marine solar saltern of the Yellow Sea in Korea. The result of 16S rRNA gene sequence analysis showed that strain SF-121 has highest sequence similarity (99·7 %) with the type strain of Bacillus halodenitrificans. Phylogenetic analyses based on 16S rRNA gene sequences revealed that B. halodenitrificans DSM 10037T and strain SF-121 are more closely related to the genus Virgibacillus than to the genus Bacillus. Strain SF-121 and B. halodenitrificans DSM 10037T exhibited 16S rRNA gene similarity levels of 95·3–97·5 % with the type strains of Virgibacillus species and 94·0 % with the type strain of Bacillus subtilis. DNA–DNA relatedness and phenotypic data indicated that B. halodenitrificans DSM 10037T and strain SF-121 are members of the same species. B. halodenitrificans DSM 10037T and strain SF-121 exhibited DNA–DNA relatedness values of 9–11 % with the type strains of Virgibacillus carmonensis and Virgibacillus marismortui. On the basis of the phenotypic, chemotaxonomic, phylogenetic and genetic data, B. halodenitrificans should be reclassified in the genus Virgibacillus as Virgibacillus halodenitrificans comb. nov.

A novel Gram-stain-positive, aerobic, motile, non-spore-forming coccus-shaped actinomycete, designated strain YIM 121300T, was isolated from alkaline sediment in Yuanjiang, Yunnan province, south-west China. Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain YIM 121300T was affiliated to the genus Kineococcus, and was closely related to Kineococcus aurantiacus IFO 15268T (97.3 % similarity). 16S rRNA gene sequence similarity to other species of the genus Kineococcus was < 97 %. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The whole-cell sugars contained arabinose, galactose, glucose, mannose and ribose. The predominant menaquinone was MK-9(H2). Mycolic acids were not detected. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown phospholipid. The predominant fatty acids were anteiso-C15 : 0 and anteiso-C15 : 1 A. The G+C content of the genomic DNA was 75.1 mol%. DNA–DNA relatedness (55 ± 4 % to K. aurantiacus IFO 15268T) and differential phenotypic data demonstrated that strain YIM 121300T was distinguished from all related species of the genus Kineococcus. On the basis of data from the present polyphasic study, the organism should be assigned to a novel species of the genus Kineococcus, for which the name Kineococcus gypseus sp. nov. is proposed. The type strain is YIM 121300T ( = CCTCC AA 2013232T = DSM 27627T).
