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 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).

Gene Sequence Analysis

The taxonomic position of a novel aerobic, Gram-positive actinobacteria, designated strain RB5T, was determined using a polyphasic approach. The strain, isolated from the gut of the fungus-farming termite Macrotermes natalensis, showed morphological, physiological and chemotaxonomic properties typical of the genus Streptomyces . Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbour of RB5T was Streptomyces polyrhachis DSM 42102T (98.87 %). DNA–DNA hybridization experiments between strain RB5T and S. polyrhachis DSM 42102T resulted in a value of 27.4 % (26.8 %). The cell wall of strain RB5T contained ll-diaminopimelic acid as the diagnostic amino acid. Mycolic acids and diagnostic sugars in whole-cell hydrolysates were not detected. The strain produced the following major phospholipids: diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannoside and phosphatidylserine. The menaquinone profile showed hexa- and octahydrogenated menaquinones containing nine isoprene units [MK-9(H6) and MK-9(H8)]. The strain exhibited a fatty acid profile containing the following major fatty acids: 12-methyltridecanoic acid (iso-C14 : 0) 12-methyltetradecanoic acid (anteiso-C15 : 0), 13-methyltetradecanoic acid (iso-C15 : 0) and 14-methylpentadecanoic acid (iso-C16 : 0). Here, we propose a novel species of the genus Streptomyces – Streptomyces smaragdinus with the type strain RB5T (=VKM Ac-2839T=NRRL B65539T).
