Actinomycete Strain

A thermophilic actinomycete, strain LA5T, was isolated from a hot spring in Yunnan province, People's Republic of China. The isolate grew aerobically at temperatures of 50–75 °C. Aerobic mycelia were not observed. Single spores were produced along the substrate hypha. Strain LA5T was characterized chemotaxonomically by having MK-7 as the predominant menaquinone and iso-C17 : 0 (27.7 %) and C16 : 0 (22.4 %) as the major fatty acids. The cell wall contained meso-diaminopimelic acid. The DNA G+C content was 56.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain LA5T belongs to the genus Planifilum. Levels of DNA–DNA relatedness between strain LA5T and Planifilum fimeticola H0165T and Planifilum fulgidum 500275T were 43.6 and 52.7 %, respectively. On the basis of phenotypic properties and phylogeny, strain LA5T represents a novel species of the genus Planifilum, for which we propose the name Planifilum yunnanense sp. nov., with the type strain LA5T (=CCTCC AA206002T=KCTC 13052T).

Actinomycete Strain

A novel actinomycete, strain YIM 45681T, which was isolated from soil in a suburb of Kunming, Yunnan Province, China, was subjected to phenotypic and genotypic characterization. The micro-organism, which produces short spore chains arranged in spirals on the aerial mycelium, was shown to have meso-diaminopimelic acid in the cell wall. The sugars present in whole-cell hydrolysates were ribose, xylose, galactose, madurose and glucose. The predominant menaquinones were MK-9(H4), MK-9(H6) and MK-9(H2). The phospholipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. The major fatty acids were iso-C16 : 1 H, C17 : 1 ω8c, 10-methyl C17 : 0 and C16 : 0. A comparative analysis of 16S rRNA gene sequences indicated that the organism formed a distinct clade within the evolutionary radiation of the family Thermomonosporaceae, and that it was closely associated with members of the genus Actinomadura. A broad range of phenotypic and genetic data supported the suggestion that this organism represents a novel species of the genus Actinomadura, for which the name Actinomadura alba sp. nov. is proposed, with YIM 45681T (=DSM 45045T =CCTCC AA206005T) as the type strain.

Taxonomic Characterization

An actinobacterial strain was isolated from subarctic forest soil, and subjected to polyphasic taxonomic characterization. The cell-wall peptidoglycan comprised meso-diaminopimelic acid, alanine and glutamic acid. MK-9(H4) was the predominant isoprenoid quinone, and iso-C17 : 0, iso-C15 : 0 and C16 : 0 were detected as the major cellular fatty acids. Phylogenetic analyses based on 16S rRNA gene sequences showed that this organism was related to members of the suborders Kineosporiineae and Micrococcineae. The phenotypic properties readily differentiated this organism from the phylogenetic neighbours. Based on the phenotypic and genotypic evidence, the strain is assigned to a novel species of a novel genus: Angustibacter luteus gen. nov., sp. nov. with type strain TT07R-79T (=NBRC 105387T =KACC 14249T).

Physiological And Biochemical

An actinomycete, strain I06-2230T, was isolated from rhizosphere soil of the plant Cephalotaxus fortunei, collected from Yunnan province, south China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belongs to the genus Actinopolymorpha. Cells grew on agar surfaces, with no penetration even after prolonged cultivation. Aerial hyphae were absent. Cells were irregularly shaped and remained attached as chains or aggregates. Chemotaxonomic data, which showed ll-diaminopimelic acid in the cell wall, glucose as the whole-cell sugar, type PI phospholipids and MK-9(H4) as the predominant menaquinone, supported the affiliation of strain I06-2230T to the genus Actinopolymorpha. The major fatty acids were iso-C15 : 0, iso-C16 : 0 and iso-C16 : 1 H. The genomic DNA G+C content was 69.3 mol%. DNA–DNA hybridization data, in combination with chemotaxonomic, physiological and biochemical data, demonstrated that strain I06-2230T should be classified as representing a novel species of the genus Actinopolymorpha. The name Actinopolymorpha cephalotaxi sp. nov. is proposed, with strain I06-2230T (=DSM 45117T=CCM 7466T=KCTC 19293T) as the type strain.

A novel endophytic actinomycete, strain GMKU 931T, was isolated from the root of a wattle tree, Acacia auriculiformis A. Cunn. ex Benth., collected at Kasetsart University, Bangkok, Thailand. Strain GMKU 931T produced short spiral chains of smooth-surfaced spores on the aerial mycelium. Lysine and meso-diaminopimelic acid were present in the cell-wall peptidoglycan. Whole-cell hydrolysates contained galactose, madurose and mannose. The predominant menaquinones were MK-9(H6) and MK-9(H8). The major fatty acids were iso-C16 : 0 and iso-C16 : 1. The major phospholipids were phosphatidylinositol and phosphatidylglycerol. A phylogenetic analysis based on 16S rRNA gene sequences suggested that strain GMKU 931T forms a distinct phyletic line within the recently proposed genus Actinoallomurus. The significant differences in phenotypic and genotypic data indicate that strain GMKU 931T represents a novel species of the genus Actinoallomurus, for which the name Actinoallomurus acaciae sp. nov. is proposed. The type strain is GMKU 931T (=BCC 28622T =NBRC 104354T =NRRL B-24610T).

Actinomycete Strain

A novel actinomycete strain, designed MW4-36T, was isolated from tropical forest soil in Nakhon Sawan Province, Thailand. Morphological and chemotaxonomic characteristics of this strain clearly demonstrated that it belongs to the genus Dactylosporangium . The strain formed finger-shaped sporangia on short sporangiophores that emerged directly from substrate hyphae. The cell-wall peptidoglycan contained glutamic acid, glycine, alanine and meso-diaminopimelic acid including 3-hydroxy-meso-diaminopimelic acid; arabinose, glucose, rhamnose, ribose and xylose were found as whole-cell sugars. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol; no phosphatidylcholine was found. The predominant menaquinones were MK-9(H8) and MK-9(H6). Mycolic acids were not detected. The predominant cellular fatty acids were iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The G+C content of the genomic DNA was 72.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences also indicated that the strain should be classified in the genus Dactylosporangium and showed that the closest relative was Dactylosporangium maewongense JCM 15933T (99.4 % similarity). These taxonomic data revealed that strain MW4-36T could be readily distinguished from its phylogenetically closest relative. On the basis of these phenotypic and genotypic data, strain MW4-36T is considered to represent a novel species, for which the name Dactylosporangium siamense sp. nov. is proposed. The type strain is MW4-36T ( = BCC 34901T = NBRC 106093T).

Taxonomic Approach

An actinomycete strain, HM7T, was isolated from sandy soil from the banks of the Arvand River, Khoramshahr, Iran. In a study conducted using a polyphasic taxonomic approach, it was found that this strain represented a novel species in the genus Nocardiopsis. Strain HM7T had long, branched substrate mycelia and the aerial mycelium completely fragmented to long chains of rod-shaped spores. The cell wall of strain HM7T contained meso-diaminopimelic acid, galactose and ribose. The predominant phospholipids were phosphatidylglycerol, phosphatidylethanolamine diphosphatidylglycerol, and phosphatidylcholine. The main menaquinones were MK-10(H2), MK-10(H4), MK-10(H0) and MK-9(H2). Strain HM7T showed the highest degree of 16S rRNA gene sequence similarity with Nocardiopsis sinuspersici UTMC 00102T (99.8 %) and Nocardiopsis quinghaiensis YIM 28A4T (99.3 %), but differed significantly from these type strains based on DNA–DNA hybridization data (37.6 and 38.9 % relatedness, respectively). Physiological, biochemical and phenotypic characteristics allowed strain HM7T to be differentiated from related species. On the basis of results from phenotypic and phylogenetic analyses, strain HM7T is considered to represent a novel species of the genus Nocardiopsis, for which the name Nocardiopsis arvandica sp. nov. is proposed; the type strain of this species is HM7T ( = UTMC 00103T = DSM 45278T = CCUG 58831T).

Taxonomical Study

Three short spore chain-forming actinomycete strains were isolated from soil samples collected from subtropical islands in Japan. The cell-wall peptidoglycan of these strains contained meso-diaminopimelic acid (meso-A2pm), glutamic acid and alanine. The major isoprenoid quinone was MK-9(H4), iso-C16 : 0 and 2-OH iso-C16 : 0 were the major cellular fatty acids and phosphatidylethanolamine was a component of the polar lipids. The G+C content of the genomic DNA was 67–69 mol%. Phylogenetic analyses based on the 16S rRNA gene sequences showed that the novel strains consistently formed a monophyletic cluster with Amycolatopsis taiwanensis. On the basis this polyphasic taxonomical study, it is proposed that the two new isolates represent two novel species: Amycolatopsis helveola (type strain TT00-43T=NBRC 103394T=KCTC 19329T) and Amycolatopsis pigmentata (type strain TT99-32T=NBRC 103392T=KCTC 19330T).
