SGP1T, a strain belonging to a lineage of the phylum Synergistetes with no previously cultivated representatives was subjected to a comprehensive range of phenotypic and genotypic tests. For good growth the strain was dependent on co-culture with, or extracts from, selected other oral bacteria. Cells of strain SGP1T were asaccharolytic and major amounts of acetic acid and moderate amounts of propionic acid were produced as end products of metabolism in peptone-yeast extract-glucose broth supplemented with a filtered cell sonicate of Fusobacterium nucleatum subsp. nucleatum ATCC 25586T (25 %, v/v). Hydrogen sulphide was produced and gelatin was weakly hydrolysed. The major cellular fatty acids were C14 : 0, C18 : 0 and C16 : 0. The DNA G+C content of strain SGP1T was 63 mol%. Phylogenetic analysis of the full-length 16S rRNA gene showed that strain SGP1T represented a novel group within the phylum Synergistetes . A novel species in a new genus, Fretibacterium fastidiosum gen. nov., sp. nov., is proposed. The type strain of Fretibacterium fastidiosum is SGP1T ( = DSM 25557T = JCM 16858T).

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).

Type Strains

Two novel isolates of rapidly growing, Gram-stain-positive, non-chromogenic species of the genus Mycobacterium , strain YIM M13028T from a sediment sample collected from the South China Sea (19° 30.261′ N 111° 0.247′ E) at a depth of 42 m and strain YIM 121001T from a coastal zone sand sample collected in Dubai, United Arab Emirates, were obtained in our laboratory. Their taxonomic positions were determined by a polyphasic approach. Good growth of the two strains was observed at 28 °C and pH 7.0 with 0–2 % NaCl on tryptic soy agar medium. Both strains formed round orange–red colonies, strain YIM M13028T had a rough surface, while YIM 121001T was smooth. Cellular fatty acids, whole-cell protein profiles and TLC analysis of their mycolic acids show significant differences from reference stains. Phenotypic characteristics and multilocus sequence analysis (MLSA) of 16S rRNA gene, hsp65, rpoB and 16S–23S internal transcribed spacer (ITS) sequences indicated that both strains YIM M13028T and YIM 121001T belong to the genus Mycobacterium . DNA–DNA hybridization values revealed a low relatedness (<70 %) of the two isolates with the type strains Mycobacterium neoaurum DSM 44074T and Mycobacterium hodleri DSM 44183T. The low DNA–DNA hybridization values (40.4±3.5 %) between strains YIM M13028T and YIM 121001T and phenotypic distinctiveness indicated that the two strains were representatives of different novel species of the genus Mycobacterium . The names proposed for these novel species are Mycobacterium sediminis sp. nov. and Mycobacterium arabiense sp. nov., and the type strains are YIM M13028T ( = DSM 45643T = KCTC 19999T) and YIM 121001T ( = DSM 45768T = JCM 18538T), respectively.
