Abstract

During our investigations of new actinobacterial taxa, a novel actinobacterial strain, designated MB20, was isolated from a Saharan soil sample, collected in the Mzab region (Ghardaïa province, southern Algeria). In order to reveal its taxonomic position, the novel strain was characterized following a polyphasic taxonomic approach. It was noticed that strain MB20 produced white, branched and fragmented substrate mycelium with no aerial mycelium on most of the media tested. Chemotaxonomic and phylogenetic studies clearly demonstrated that strain MB20 belonged to the family and was closely related to the genus . Cell-wall hydrolysates contained -diaminopimelic acid but not glycine, and whole-cell hydrolysates contained galactose, glucose and ribose. The diagnostic phospholipid was phosphatidylethanolamine. Mycolic acids were not detected while the predominant fatty acid was found to be iso-branched hexadecanoate (iso-C). The major menaquinone was MK-9(H). Results of the 16S rRNA gene sequence comparison revealed that strain MB20shared the highest degree of similarity with DSM 45828 (98.5 %), DSM 45659 (98.0 %) and DSM 45660 (97.5 %). However, DNA–DNA hybridization studies showed only 32.9 % similarity with , 23.7 % similarity with and 17.9 % similarity with . On the basis of phenotypic characteristics, 16S rRNA gene sequence comparisons and DNA–DNA hybridization, strain MB20 was revealed to be a representative of a novel species of the genus , for which the name sp. nov. (type strain MB20 =DSM 46746 =CECT 8960) is proposed.
