Abstract

A halophilic actinomycete, designated HT371^T, was isolated from a soil sample collected from the shore of the salty Lake Qaroun, Egypt, and was the subject of a polyphasic study. Analysis of 16S rRNA indicated that the isolate belonged to the genus Actinopolyspora and constituted a separate clade in the Actinopolyspora 16S rRNA gene tree with similarity values of 96.5 and 96.2% with Actinopolyspora halophila DSM43834^T and Actinopolyspora mortivallis DSM44261^T, respectively. Isolate HT371^T had chemotaxonomic and morphological properties consistent with its classification in the genus Actinopolyspora and could grow on agar plates at NaCl concentrations of up to 25% (w/v). The isolate was readily differentiated from the type strains of genus Actinopolyspora using a range of phenotypic characters. On the basis of polyphasic evidence, the strain HT371^T represents a novel species for which the name Actinopolyspora egyptensis sp. nov. is proposed. The type strain is HT371^T (=CGMCC 4.2041^T).

Key words: Actinopolyspora egyptensis sp. nov., halophilic isolate, polyphasic taxonomy.
