Abstract: A strain HCCB10124 was isolated from the soil against pathogenic fungus Verticillium dahliae.The growth of 10 plant pathogens and some bacteria were strongly inhibitded by strain HCCB10124 on PDA plate, but unconspicuous effects on bacteria comparatively. The morphology, cultural characteristics,physiological and biochemical properties ,chemotaxonomy and 16S rDNA sequences of this strain were studied. The results exhibited that the homology of 16S rDNA between Streptomyces strain HCCB10124 and Streptomyces albireticuli reached 99%. A phylogenetic tree was constructed by comparing with the published 16S rDNA sequences of the related species. According to the multiclassification principle and the phylogenetic analysis, the Streptomyces strain HCCB10124 should be nomenclatured as Streptomyces albireticuli.

Key words: Streptomyces strain HCCB10124, antimicrobial activity, screening and identification, Streptomyces albireticuli, Streptomyces strain HCCB10124, antimicrobial activity, screening and identification
