Taxonomy and antimicrobial activity of streptosporangium strain SG163 isolated from a Saharan soil
Year: 2019
Type: article
Abstract: n a continuing search fornew antimicrobial products from actinobacteriacollected in Algerian Saharan soils, an isolateof actinobacteria,designated Sg163, was selected for its interesting antimicrobial activity.The isolate wasidentified to the genus Streptosporangium by phenotypicand molecular criteria. The cultural and physiological characterizations as well as phylogenetic analysis indicated that the isolate was different from known members of the genus Streptosporangium. Analysis of the 16S rRNA sequence showed 97.09to 98.27% similarity with those of Streptosporangium type strains. The strainSg163 produced antifungal and antibacterial activities on several culture media. The highest antimicrobial activities were obtained in ISP2 medium. Three active products C1, C2 and C3 with both antifungal and antibacterial activities were isolated and purified by chromatographic methodswith C2, as the major compound. The data of the infraredspectroscopy andthe chemical revelations, suggested that the active molecules were glycosylatedaromaticcompounds.
