Abstract:
A halophilic actinomycete strain, designated H55 T , was isolated from Saharan soil sampled in the Mzab region (Ghardaïa, southern Algeria) and was characterized in a taxonomic study using a polyphasic approach. The cell wall was determined to contain meso -diaminopimelic acid and the characteristic whole-cell sugars were arabinose and galactose. The predominant menaquinones were found to be MK-10(H 4 ) and MK-9(H 4 ). The predominant cellular fatty acids were determined to be anteiso-C 17 : 0 , iso-C 16 : 0 and iso-C 15 : 0 . The diagnostic phospholipid detected was phosphatidylcholine. The morphological and chemotaxonomic characteristics of the strain were consistent with those of members of the genus Actinopolyspora , and 16S rRNA gene sequence analysis confirmed that strain H55 T was a member of this genus. DNA–DNA hybridization values between strain H55 T and the type strains of the nearest species of the genus Actinopolyspora , Actinopolyspora erythraea and A. alba , were clearly below the 70 % threshold. The genotypic and phenotypic data showed that the organism represents a novel species of the genus Actinopolyspora , for which the name Actinopolyspora mzabensis sp. nov. is proposed, with the type strain H55 T ( = DSM 45460 T = CCUG 62965 T ).
