Abstract:
A Gram-staining-positive actinobacterial strain, Chem10 T , was isolated from soil around Inche-Broun hypersaline wetland in the north of Iran. Strain Chem10 T was strictly aerobic, and catalase- and oxidase-positive. The isolate grew with 0–3 % NaCl, at 20–40 °C and at pH 6.0–8.0. The optimum temperature and pH for growth were 30 °C and pH 7.0, respectively. The cell wall of strain Chem10 T contained meso -diaminopimelic acid as diamino acid and galactose, ribose and arabinose as whole-cell sugars. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Strain Chem10 T synthesized cellular fatty acids of the straight-chain saturated and mono-unsaturated, and iso- and anteiso-branched types C 14 : 0 , C 16 : 0 , iso-C 16 : 1 , anteiso-C 17 : 0 , iso-C 16 : 0 , iso-C 14 : 0 and iso-C 15 : 0 , and the major respiratory quinone was MK-9(H 4 ). The G+C content of the genomic DNA was 70.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Chem10 T belonged to the family Pseudonocardiaceae and showed the closest phylogenetic similarity to Alloactinosynnema album KCTC 19294 T (98.3 %) and Actinokineospora cibodasensis DSM 45658 T (97.9 %). DNA–DNA relatedness values between the novel strain and strains Alloactinosynnema album KCTC 19294 T and Actinokineospora cibodasensis DSM 45658 T were only 52 % and 23 %, respectively. On the basis of phylogenetic analysis, phenotypic characteristics and DNA–DNA hybridization data, a novel species of the genus Alloactinosynnema is proposed, Alloactinosynnema iranicum sp. nov. The type strain is Chem10 T ( = IBRC-M 10403 T = CECT 8209 T ). In addition, an emended description of the genus Alloactinosynnema is proposed.
