Abstract:
A novel γ-radiation-resistant and Gram-staining-positive actinobacterium designated BMG 8133 T was isolated from a limestone collected in the Sahara desert of Tunisia. The strain produced dry, pale-pink colonies with an optimum growth at 35–40 °C and pH 6.5–8.0. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Geodermatophilus . The peptidoglycan contained meso -diaminopimelic acid as diagnostic diamino acid. The main polar lipids were phosphatidylcholine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine and one unspecified glycolipid. MK-9(H 4 ) was the dominant menaquinone. Galactose and glucose were detected as diagnostic sugars. The major cellular fatty acids were branched-chain saturated acids iso-C 16 : 0 and iso-C 15 : 0 . The DNA G+C content of the novel strain was 74.5 %. The 16S rRNA gene sequence showed highest sequence identity with Geodermatophilus ruber (98.3 %). Based on phenotypic results and 16S rRNA gene sequence analysis, strain BMG 8133 T is proposed to represent a novel species, Geodermatophilus sabuli sp. nov. The type strain is BMG 8133 T ( = DSM 46844 T = CECT 8820 T ).
