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 Gram-stain-positive, coccoid actinobacterium, designated strain Sco-D01T, was isolated from volcanic ash collected from Oreum (a parasitic volcanic cone) on Jeju Island, Republic of Korea. Cells were aerobic, oxidase-negative and catalase-positive. Colonies were vivid yellow, circular, smooth and convex. The diagnostic diamino acid in the cell wall was ll-diaminopimelic acid. The predominant menaquinone was MK-8(H4). The polar lipids were phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and an unknown phospholipid. The fatty acid profile was represented by large amounts of saturated, unsaturated, 10-methyl and hydroxyl components. The DNA G+C content of strain Sco-D01T was 72.0 mol%. 16S rRNA gene sequence analysis revealed that strain Sco-D01T belonged to the family Nocardioidaceae and formed a distinct sublineage within the radiation of the genus Marmoricola. The level of DNA–DNA relatedness between strain Sco-D01T and its closest phylogenetic relative, Marmoricola aurantiacus DSM 12652T, was 30.2 % (35.4 % in duplicate measurements). On the basis of phenotypic and DNA–DNA hybridization data, strain Sco-D01T is considered to represent a novel species of the genus Marmoricola, for which the name Marmoricola scoriae sp. nov. is proposed. The type strain is Sco-D01T (=KCTC 19597T=DSM 22127T).

A novel Gram-reaction-positive, aerobic and non-spore-forming rod-shaped bacterial strain, YS17T, was isolated from ripened Pu′er tea. Growth of the strain was observed at 15–50 °C (optimum 30–37 °C) and at pH 5.5–10.5 (optimum 6.0–9.5). Phylogenetic analysis of 16S rRNA gene sequences indicated that the strain represented a member of the genus Aeromicrobium. The strains most closely related to YS17T were Aeromicrobium erythreum DSM 8599T, Aeromicrobium alkaliterrae JCM 13518T and Aeromicrobium ginsengisoli JCM 14732T, with 16S rRNA gene sequence similarities of 96.8, 96.8 and 96.7 %, respectively. DNA–DNA hybridization of YS17T with the type strains of the most closely related species, A. erythreum DSM 8599T, A. alkaliterrae JCM 13518T and A. ginsengisoli JCM 14732T, yielded reassociation values of 10.9, 16.8 and 10.9 %, respectively. The diagnostic diamino acid of the cell wall peptidoglycan was ll-diaminopimelic acid. The predominant menaquinones were menaquinone MK-9(H4) (76 %) and MK-8(H4) (17 %). The major fatty acids were C16 : 0, 10-methyl C18 : 0 and C18 : 1ω9c. The DNA G+C content of YS17T was 66 mol%. YS17T could be differentiated from recognized species of the genus Aeromicrobium on the basis of phenotypic characteristics, chemotaxonomic differences, phylogenetic analysis and DNA–DNA hybridization data. On the basis of evidence from the polyphasic analyses performed as part of this study a novel species, Aeromicrobium camelliae sp. nov., is proposed, with strain YS17T ( = CGMCC 1.12942T = JCM 30952T) as the type strain.

A novel actinobacterium, designated strain C4-31T, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder Frankineae, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C16 : 0, C17 : 1ω6c and C16 : 0. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31T ( = KCTC 39556T = DSM 100065T) is considered to represent the type strain of a novel species of a new genus in the suborder Frankineae, for which the name Antricoccus suffuscus gen. nov., sp. nov. is proposed.

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).

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, mycelium-forming actinobacterium (05-Be-005T) isolated from the wall of an indoor environment was studied for its taxonomic position. The isolated strain formed a substrate mycelium that fragmented into rod-shaped cells and showed an aerial mycelium on medium M79. On the basis of 16S rRNA gene sequence similarity studies, strain 05-Be-005T was shown to belong to the genus Prauserella, closely related to Prauserella rugosa DSM 43194T (96.6 % similarity), Prauserella alba YIM 90005T (95.9 %) and Prauserella halophila YIM 90001T (95.4 %). The predominant menaquinone was MK-9(H4); whole-cell hydrolysates contained meso-diaminopimelic acid as the diagnostic diamino acid of the cell wall and arabinose and galactose as the main sugars. Mycolic acids were absent. The polar lipid profile consisted of the lipids diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylserine and an unknown phospholipid. Major fatty acids C16 : 0 iso, C16 : 0, C17 : 1 ω8c and C17 : 1 ω6c supported the affiliation of strain 05-Be-005T to the genus Prauserella. The results of physiological and biochemical tests allowed clear phenotypic differentiation of strain 05-Be-005T from the three known Prauserella species. Strain 05-Be-005T represents a novel Prauserella species, for which we propose the name Prauserella muralis sp. nov., with the type strain 05-Be-005T (=CCUG 57426T =NRRL B-24780T =CCM 7635T=DSM 45305T).
