Actinopolyspora egyptensis sp nov., a new halophilic actinomycete

Lookup NU author(s): Dr Wael Hozzein, Professor Michael Goodfellow



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)).
