| Popis: | A mesophilic, Gram-stain-positive, spore-forming bacterium that formed branched mycelia was isolated from paddy soil in Gunung Salak (Mount Salak), West Java, Indonesia. This strain, designated S-27T, grew at temperatures between 20 and 37 °C; the optimum growth temperature was 25 to 30 °C, and no growth was observed at 15 or 45 °C. The pH range for growth was pH 3.5 to 8.6; the optimum pH was 6.0, and no growth was observed at pH 3.0 or 9.2. Strain S-27T was able to hydrolyse polysaccharides such as starch, cellulose and xylan. The G+C content of the DNA of strain S-27T was 55.7 mol%. The major fatty acids were iso-C17 : 0 and C16 : 1 2-OH, and the major menaquinone was MK-9 (H2). The cell wall of strain S-27T contained d-glutamic acid, glycine, l-alanine, d-alanine, l-ornithine and β-alanine in a molar ratio of 1.0 : 1.6 : 1.4 : 0.6 : 0.9 : 1.1. The polar lipids consisted of phosphatidylglycerol, phosphatidylinositol and two glycolipids. The major cell-wall sugar was arabinose. Detailed phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S-27T belongs to the order Ktedonobacterales and is most closely related to Ktedonobacter racemifer SOSP1-21T (89.6 % sequence identity). On the basis of its chemotaxonomic and phenotypic features and phylogenetic position, we concluded that strain S-27T represents a novel genus and species, for which we propose the name Dictyobacter aurantiacus gen. nov., sp. nov. The type strain of Dictyobacter aurantiacus is strain S-27T (=NBRC 109595T=InaCC B312T). Emendation of the description of the genus Thermosporothrix is also provided. |
