Abstract

A novel actinomycete, strain S10, was isolated from rhizosphere soil of wild in Thinghir, Ouarzazate Province, Southern Morocco. The taxonomic status of this strain was established using a polyphasic approach. Strain S10 had white–grey aerial mycelium with long, spiral spore chains bearing smooth surfaced spores and produced a yellow diffusible pigment. Chemotaxonomic analyses showed that the cell wall of strain S10 contained -diaminopimelic acid and glycine. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that strain S10 belonged to the Group I streptomycetes, branching off next to LMG 23016 from the group. DNA–DNA relatedness and phenotypic data distinguished strain S10 from the phylogenetically closest related type strains. It is therefore proposed that strain S10 (=CCMM B35=DSM 41919) represents the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
