A novel actinobacterial strain, designated P4-5T, was isolated from soil of a ginseng field located in Geumsan County, Republic of Korea. Cells of strain P4-5T were Gram-stain-positive, oxidase- and catalase-positive, motile, short rods and the strain produced creamy white colonies on trypticase soy agar. The isolate contained demethylmenaquinone 7 (DMK-7) as the predominant isoprenoid quinone, C18 : 1ω9c and anteiso-C15 : 0 as major fatty acids, diphosphatidylglycerol, phosphatidylglycerol and several unknown lipids in the polar lipid profile, galactose, glucose, mannose, arabinose, xylose (trace) and rhamnose as cell-wall sugars, and meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The DNA G+C content of strain P4-5T was 74.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain P4-5T was related most closely to Patulibacter minatonensis KV-614T and Patulibacter americanus CP177-2T (98.4 and 98.2 % similarity, respectively) and that it formed a separate lineage in the genus Patulibacter. Combined phenotypic and DNA–DNA hybridization data supported the conclusion that strain P4-5T represents a novel species of the genus Patulibacter, for which the name Patulibacter ginsengiterrae sp. nov. is proposed. The type strain is P4-5T ( = KCTC 19427T  = CECT 7603T). An emended description of the genus Patulibacter is also provided.

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 Gram-positive, coccoid-shaped organism (strain 02-Je-010T), forming yellow-pigmented colonies was isolated from the wall of an indoor environment. On the basis of 16S rRNA gene sequence similarity studies, it was shown that strain 02-Je-010T belongs to the genus Citricoccus with sequence similarities of 98.9 % to Citricoccus alkalitolerans DSM 15665T and 98.6 % to Citricoccus muralis DSM 14442T. Cell-wall sugars were mannose and glucose. The diagnostic diamino acid of the peptidoglycan was lysine. The major menaquinones detected were MK-9(H2) and MK-8(H2). The polar lipid profile consisted of the major lipids diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol and moderate amounts of two unknown phospholipids and two unknown glycolipids. The fatty acid profile comprised major amounts of anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0. All these data supported the affiliation of strain 02-Je-010T to the genus Citricoccus. The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 02-Je-010T from the two recognized Citricoccus species. For these reasons, strain 02-Je-010T represents a novel species, for which the name Citricoccus parietis sp. nov. is proposed, with the type strain 02-Je-010T (=CCUG 57388T=CCM 7609T).

Five Gram-stain-positive, motile, aerobic strains were isolated from a clean room of the Kennedy Space Center where the Phoenix spacecraft was assembled. All strains are rod-shaped, spore-forming bacteria, whose spores were resistant to UV radiation up to 1000 J m−2. The spores were subterminally positioned and produced an external layer. A polyphasic taxonomic study including traditional biochemical tests, fatty acid analysis, cell-wall typing, lipid analyses, 16S rRNA gene sequencing and DNA–DNA hybridization studies was performed to characterize these novel strains. 16S rRNA gene sequencing and lipid analyses convincingly grouped these novel strains within the genus Bacillus as a cluster separate from already described species. The similarity of 16S rRNA gene sequences among the novel strains was >99 %, but the similarity was only about 97 % with their nearest neighbours Bacillus pocheonensis, Bacillus firmus and Bacillus bataviensis. DNA–DNA hybridization dissociation values were <24 % to the closest related type strains. The novel strains had a G+C content 35.6±0.5 mol% and could liquefy gelatin but did not utilize or produce acids from any of the carbon substrates tested. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0 and the cell-wall diamino acid was meso-diaminopimelic acid. Based on phylogenetic and phenotypic results, it is concluded that these strains represent a novel species of the genus Bacillus, for which the name Bacillus horneckiae sp. nov. is proposed. The type strain is 1P01SCT (=NRRL B-59162T =MTCC 9535T).

A novel actinomycete, designated strain Sco-A36T, was isolated from volcanic ash. Cells were aerobic, Gram-stain-positive, oxidase-negative, catalase-positive, non-motile cocci; colonies were yellow-coloured, smooth, entire and convex. Phylogenetic analysis showed that the organism formed a distinct phyletic line within the radiation of the genus Marmoricola. Its closest phylogenetic neighbours were Marmoricola aurantiacus DSM 12652T (97.9 % 16S rRNA gene sequence similarity), Marmoricola scoriae Sco-D01T (97.9 %), Marmoricola aequoreus SST-45T (97.4 %) and Marmoricola bigeumensis MSL-05T (96.3 %). The diagnostic diamino acid in the cell walls was ll-diaminopimelic acid. The predominant menaquinone was MK-8(H4). The polar lipids contained phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and an unknown phospholipid. The predominant fatty acids were C16 : 0, C17 : 1ω8c, C18 : 1ω9c and C16 : 1ω7c and/or iso-C15 : 0 2-OH. The DNA G+C content of strain Sco-A36T was 71.0 mol%. Levels of DNA–DNA relatedness between the new isolate and the type strains of recognized species of the genus Marmoricola were 4.9–29.2 %. The phenotypic and DNA–DNA hybridization data presented here strongly suggest that strain Sco-A36T represents a novel species of the genus Marmoricola, for which the name Marmoricola korecus sp. nov. is proposed. The type strain is Sco-A36T ( = KCTC 19596T = DSM 22128T).

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).

A novel Gram-stain-positive actinobacterium, designated H25-14T, was isolated from a sea sediment sample, and its taxonomic position was investigated by a polyphasic approach. The peptidoglycan type of strain H25-14T was A4α and lysine was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-9(H4) and the major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. The DNA G+C content was 73.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain H25-14T was closely related to Paraoerskovia marina NBRC 104352T (98.3 %). However, DNA–DNA hybridization data and phenotypic characteristics revealed that strain H25-14T differed from P. marina NBRC 104352T. Therefore, strain H25-14T represents a novel species of the genus Paraoerskovia , for which the name Paraoerskovia sediminicola sp. nov. is proposed. The type strain is H25-14T ( = NBRC 108565T = DSM 25477T). An emended description of the genus Paraoerskovia is also proposed.

Marine Sediment Sample

A novel Gram-stain-positive, spore-forming, aerobic, non-motile, rod-shaped bacterium designated strain SD111T that forms red-pigmented colonies was isolated from a marine sediment sample (collected from 5 m depth) from Lakshadweep, India. Strain SD111T grew well on seawater agar at pH 6–10 (optimum pH 7.5±0.2). It showed maximum (97.6 %) 16S rRNA gene sequence similarity and formed a monophyletic clade with Domibacillus robiginosus WS 4628T ( = DSM 25058T). The genomic DNA G+C content was 37.4 mol% and the strain showed 37.7 % DNA–DNA relatedness to D. robiginosus DSM 25058T. The major fatty acids were anteiso-C15 : 0, C16 : 0, iso-C15 : 0 and iso-C16 : 0 and MK-6 was the predominant quinone. The polar lipid profile of strain SD111T consisted of unidentified phospholipids (PL1 and PL2), phosphatidylglycerol (PG) and diphosphatidylglycerol (DPG). The cell wall contained meso-diaminopimelic acid and the peptidoglycan was of A1γ type. Glucose and ribose were detected as major cell-wall sugars. Results from polyphasic studies indicated that SD111T represents a novel species of the genus Domibacillus for which the name Domibacillus indicus sp. nov. is proposed. The type strain is SD111T ( = MCC 2255T = DSM 28032T).

A total of 14 Halomonas strains were isolated from the blood of two patients and from dialysis machines of a renal care centre. The strains were Gram-negative, halophilic, motile and non-spore-forming rods. They produced cream-coloured colonies and contained Q-9 as the predominant ubiquinone and C18 : 1 ω7c and C16 : 0 as the major fatty acids. Phylogenetic analysis based on 16S rRNA gene sequencing showed that the 14 isolates were most closely related to Halomonas magadiensis 21 MIT with 98.1–98.9 % sequence similarity and that they formed three separate lineages among themselves. Combined phenotypic and DNA–DNA hybridization data support the conclusion that they represent three novel species of the genus Halomonas, for which the names Halomonas stevensii sp. nov. (type strain S18214T=KCTC 22148T=DSM 21198T), Halomonas hamiltonii sp. nov. (type strain W1025T=KCTC 22154T=DSM 21196T) and Halomonas johnsoniae sp. nov.

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.
