| Abstract |
A Gram-stain-positive, aerobic bacterium, designated CPCC 204705T, was isolated from a desert soil sample, collected from the Badain Jaran desert. Growth of strain CPCC 204705T was observed at pH 6.0-8.0 and 15-37 °C, with optimal growth at 28 °C and pH 7.0. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CPCC 204705T belonged to the genus Cellulomonas, showing the highest similarity (98.54 %) of 16S rRNA gene sequence to Cellulomonas oligotrophica JCM 17534T. The peptidoglycan type was A4β, containing d-ornithine and d-glutamic acids as diagnostic amino acids. Rhamnose and galactose were detected in the whole-cell hydrolysate as diagnostic sugars. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C15 : 1A, C14 : 0 and C16 : 0. The major menaquinone was MK-9 (H4) and the polar lipid system contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, one unidentified lipid, one unidentified aminolipid and two unidentified aminophospholipids. The DNA-DNA hybridization value between strain CPCC 204705T and C. oligotrophica JCM 17534T was 7.1±0.4 %, and the value of average nucleotide identity between these two strains was 79.8 %. The DNA G+C content of strain CPCC 204705T was 75.4 mol%. Based on the results of physiological experiments, chemotaxonomic data, phylogenetic analysis and DNA-DNA hybridization value, strain CPCC 204705T should be classified as a novel Cellulomonas species. The name Cellulomonas telluris sp. nov. is proposed, with strain CPCC 204705T (=DSM 105430T=KCTC 39974T) as the type strain. |
