A Gram-positive bacterium, strain M-6-3T, was isolated from salt-fermented seafood in Korea. The organism grew in 0–10 % (w/v) NaCl and at 25–37 °C, with optimal growth occurring in 5 % NaCl and at 28–30 °C. The peptidoglycan type was variation A4γ with meso-diaminopimelic acid as the diagnostic cell-wall diamino acid. The polar lipid profile of strain M-6-3T consisted of diphosphatidylglycerol, phosphatidylglycerol, an unidentified phospholipid and an unknown glycolipid. Strain M-6-3T contained MK-7 as the major component of the quinone system and anteiso-C15 : 0 (62.1 %) as the predominant fatty acid. Based on 16S rRNA gene sequence similarity studies, strain M-6-3T was most closely related to Brachybacterium rhamnosum LMG 19848T (98.5 %). The G+C content of the genomic DNA was 71.5 mol% and the mean DNA–DNA hybridization value with reference strains was 14.32±2.0 %. Based on phenotypic, genotypic and phylogenetic analyses, it is proposed that strain M-6-3T represents a novel species for which the name Brachybacterium squillarum sp. nov. is proposed; the type strain is M-6-3T ( = KACC 14221T  = JCM 16464T).

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.

An orange-pigmented, Gram-staining-negative, rod-shaped bacterium, designated 96_Hippo_TS_3/13T was isolated from the brood pouch of a diseased seahorse male of the species Hippocampus barbouri from the animal facility of the University of Giessen, Germany. Phylogenetic analyses based on the nearly full-length 16S rRNA gene sequence placed strain 96_Hippo_TS_3/13T into the monophyletic cluster of the genus Mesonia within the family Flavobacteriaceae. However, the strain shared only 92.2–93.8 % sequence similarity to type strains of species of the genus Mesonia, with highest sequence similarity to the type strain of Mesonia aquimarina. Cellular fatty acid analysis showed a Mesonia-typical fatty acid profile including several branched and hydroxyl fatty acids with highest amounts of iso-C15 : 0 (40.9 %) followed by iso-C17 : 0 3-OH (14.8 %). In the polyamine pattern, sym-homospermidine was predominant. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The quinone system contained exclusively menaquinone MK-6. The only identified compound in the polar lipid profile was phosphatidylethanolamine present in major amounts. Additionally, major amounts of an unidentified aminolipid and two unidentified lipids not containing a phosphate group, an amino group or a sugar residue were detected. The genomic G+C content of strain 96_Hippo_TS_3/13T was 30 mol%. Based on genotypic, chemotaxonomic and physiological characterizations we propose a novel species of the genus Mesonia, Mesonia hippocampi sp. nov., with strain 96_Hippo_TS_3/13T ( = CIP 110839T =  LMG 28572T = CCM 8557T) as the type strain. An emended description of the genus Mesonia is also provided.

A Gram-stain-positive, rod-shaped, motile bacterial strain, designated 3-2-2T, was isolated from field topsoil collected from a western suburb of Nanyang city, Henan province, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 3-2-2T was a member of the genus Bacillus and most closely related to Bacillus fortis R-6514T (98.9 % similarity), Bacillus terrae RA9T (98.0 %) and Bacillus fordii R-7190T (97.7 %). A draft genome sequence determined for strain 3-2-2T revealed a DNA G+C content of 42.2 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between 3-2-2T and the closely related Bacillus species ranged 79.4–84.2 % and 23.4–24.6 %. The major fatty acids of strain 3-2-2T were iso-C15 : 0, anteiso-C15 : 0, iso-C14 : 0 and iso-C16 : 0. The major isoprenoid quinone was MK-7. meso-Diaminopimelic acid was detected in the peptidoglycan. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid and an unidentified lipid. The results of phylogenetic analyses, in silico genomic comparisons, and chemotaxonomic and phenotypic analyses clearly indicated that strain 3-2-2T represents a novel species within the genus Bacillus , for which the name Bacillus acidinfaciens sp. nov. is proposed. The type strain is 3-2-2T (=CGMCC 1.13685T=LMG 30839T).

A bacterial strain, PY2T, capable of oxidizing carbon monoxide, was isolated from a soil sample collected from a roadside at Yonsei University, Seoul, Korea. On the basis of 16S rRNA gene sequence analysis, strain PY2T was shown to belong to the genus Terrabacter and was most closely related to Terrabacter lapilli LR-26T (99.1 % similarity). Strain PY2T was characterized chemotaxonomically as having iso-C15 : 0 as the predominant fatty acid, MK-8(H4) as the major menaquinone, ll-diaminopimelic acid as the diagnostic diamino acid of the cell wall, as possessing a polar lipid profile that included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and unknown amino-containing phosphoglycolipids, and having a DNA G+C content of 75.6 mol%. DNA–DNA relatedness values between strain PY2T and the type strains of T. lapilli, Terrabacter tumescens, Terrabacter terrae and Terrabacter aerolatus were 20.0 %, 22.9 %, 35.9 % and 64.5 %, respectively. Based on the combined evidence from the phylogenetic analyses, chemotaxonomic data and DNA–DNA hybridization experiments, it is proposed that strain PY2T represents a novel species for which the name Terrabacter carboxydivorans sp. nov. is proposed. The type strain is PY2T (=KCCM 42922T=JCM 16259T).

A novel, yellow-pigmented actinobacterium was isolated from a small stone collected in Jeju, Republic of Korea. The cells of the organism, designated strain R-Ac013T, were Gram-positive, aerobic, non-motile cocci that occurred singly or in pairs. The strain showed growth at 10–37 °C and pH 4.1–11.1, and tolerated 2 % NaCl. On the basis of the 16S rRNA gene sequence, the organism was phylogenetically related to members of the genera Tetrasphaera (94.6–97.1 % sequence similarity), Terrabacter (96.5 %), Knoellia (96.4 %), Terracoccus (96.4 %), Oryzihumus (96.4 %), Janibacter (96.1–96.4 %) and Intrasporangium (96.2 %). The chemotaxonomic results for the organism were as follows: ll-diaminopimelic acid as the diagnostic diamino acid in the peptidoglycan, acetyl-type murein, MK-8(H4) as the major menaquinone, a DNA G+C content of 74.1 mol%, and a polar lipid profile that comprised diphosphatidylglycerol and phosphatidylinositol. The fatty acid profile consisted of iso- and anteiso-methyl-branched, straight-chain saturated and monounsaturated types, the major components being iso-C16 : 0, C17 : 1 ω8c and iso-C15 : 0. The combination of the phenotypic and phylogenetic data revealed that this strain represents a novel genus and species of the family Intrasporangiaceae, for which the name Lapillicoccus jejuensis gen. nov., sp. nov. is proposed. The type strain is strain R-Ac013T (=KCTC 19200T=DSM 18607T).

A Gram-reaction-positive, rod-shaped, non-motile, non-spore-forming bacterium (strain BX5-10T) was isolated from the soil of a ginseng field on Baekdu Mountain in Jilin district, China. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain BX5-10T was shown to belong to the family Nocardioidaceae and to be most closely related to Nocardioides plantarum NCIMB 12834T (96.5 % sequence similarity), Nocardioides dokdonensis KCTC 19309T (96.2 %) and Nocardioides fonticola NAA-13T (95.1 %). Strain BX5-10T was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone and C18 : 1ω9c, C16 : 0 and C17 : 1ω8c as its major fatty acids. The G+C content of the genomic DNA was 70.3 mol%. The novel strain could be differentiated genotypically and phenotypically from all recognized species of the genus Nocardioides. Based on the results of the phylogenetic analyses and the genotypic and phenotypic data, a novel species, Nocardioides ginsengagri sp. nov., is proposed. The type strain is BX5-10T ( = KCTC 19467T = DSM 21362T).

A Gram-stain-positive, rod-shaped, non-endospore-forming, orange-pigmented (coloured) actinobacterium (01-Je-003T) was isolated from the wall of an indoor environment primarily colonized with moulds. On the basis of 16S rRNA gene sequence similarity studies, strain 01-Je-003T was shown to belong to the genus Brevibacterium and was most similar to the type strains of Brevibacterium picturae (98.8 % similarity), Brevibacterium marinum (97.3 %) and Brevibacterium aurantiacum (97.2 %). Chemotaxonomic data [predominant quinone menaquinone MK-8(H2); polar lipid profile consisting of major compounds diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid; characteristic cell-wall diamino acid meso-diaminopimelic acid; polyamine pattern showing major compounds putrescine and cadaverine; major fatty acids anteiso-C15 : 0 and anteiso-C17 : 0] supported the affiliation of strain 01-Je-003T to the genus Brevibacterium. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 01-Je-003T from the two most closely related species, B. picturae and B. marinum. Strain 01-Je-003T therefore represents a novel species, for which the name Brevibacterium sandarakinum sp. nov. is proposed, with the type strain 01-Je-003T (=DSM 22082T =CCM 7649T).

Strain F2AT, isolated from the cricket Acheta domesticus, was subjected to a polyphasic taxonomic characterization. Cells of the strain were rod-shaped, Gram-stain-negative and catalase- and oxidase-positive. It did not assimilate any carbohydrates. The strain's 16S rRNA gene sequence showed highest similarity to Entomomonas moraniae QZS01T (96.4 %). The next highest similarity values were found to representatives of related genera (<93 %). The genome size of strain F2AT was 3.2 Mbp and the G+C content was 36.4 mol%. Average nucleotide identity values based on blast and MUMmer and average amino acid identity values between strain F2AT and E. moraniae QZS01T were 74.29/74.43, 83.88 and 74.70 %, respectively. The quinone system predominantly contained ubiquinone Q-8. In the polar lipid profile, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified phospholipid were detected. The polyamine pattern consisted of the major compounds putrescine and spermidine. Major fatty acids were C18 : 1 ω7c and C16 : 0 and the hydroxyl acids were C12 : 0 3-OH, C14 : 0 2-OH and C14 : 0 3-OH. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. Due to its association with the only species of the genus Entomomonas but its distinctness from E. moraniae we here propose the novel species Entomomonas asaccharolytica sp. nov. F2AT (=CCM 9136T=LMG 32211T).

A Gram-positive, non-motile, coccoid-shaped, non-spore-forming halophilic bacterial strain, BY-5T, was isolated from a marine solar saltern in Korea and its taxonomic position was investigated by using a polyphasic approach. The novel strain grew optimally at 37 °C and in the presence of 10 % (w/v) NaCl. Strain BY-5T had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, MK-7 as the predominant menaquinone and anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C17 : 0 as the major fatty acids. The DNA G+C content was 47.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain BY-5T formed a coherent cluster with Bacillus halophilus and Marinococcus albus. Strain BY-5T exhibited 16S rRNA gene sequence similarity values of 98.7 and 97.4 % to the type strains of B. halophilus and M. albus, respectively. Strain BY-5T was distinguished from B. halophilus and M. albus by several phenotypic properties and DNA–DNA relatedness data. On the basis of the combined chemotaxonomic and phylogenetic data, it is proposed that M. albus, B. halophilus and strain BY-5T should be placed in a new genus as three separate species. Marinococcus albus and Bacillus halophilus are reclassified in a new genus, Salimicrobium gen. nov., as Salimicrobium album comb. nov. and Salimicrobium halophilum comb. nov., respectively. The type species of the new genus is Salimicrobium album. Strain BY-5T (=KCTC 3989T=CIP 108918T) is placed in the genus Salimicrobium as a novel species Salimicrobium luteum sp. nov.

A novel actinomycete strain, designated CS5-AC15T, was isolated from a soil sample collected from a cliff on Mara Island, Jeju, Republic of Korea, and subjected to a polyphasic taxonomic analysis. The isolate produced well-developed, yellow substrate mycelium and white aerial mycelium that differentiated into straight or flexuous chains of smooth-surfaced spores. 16S rRNA gene sequence analyses showed that the organism belonged to the family Thermomonosporaceae and formed a tight cluster with the type strain of Actinomadura oligospora (97.4 % sequence similarity). Chemotaxonomic characteristics were consistent with its assignment to the genus Actinomadura in that the isolate had meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall, madurose as the characteristic sugar, N-acetyl type of murein in the peptidoglycan, MK-9(H6) and MK-9(H8) as major menaquinones and a polar lipid profile containing diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown phospholipids. Mycolic acids were not detected. The predominant fatty acids were C16 : 0, C18 : 1ω9c and iso-C16 : 0. The DNA G+C content was 70.9 mol%. DNA relatedness of strain CS5-AC15T and A. oligospora JCM 10648T was 37.9±0.7 %. On the basis of the phenotypic, phylogenetic and DNA–DNA hybridization data, strain CS5-AC15T is assigned to a novel species of the genus Actinomadura, for which the name Actinomadura rupiterrae sp. nov. is proposed (type strain CS5-AC15T  = KCTC 19559T  = DSM 45251T).
