Abstract

Background and Objective: The Streptomycetes are gram positive, no motile and filamentous bacteria. STREPTOMYCES is the largest antibiotic-producing genus in the microbial world discovered so far. In this research our goal is isolation Streptomycetes with antibacterial activity from some regions of North West of Iran including Tabriz, marand, khoy, maku in varius season of the year.Materials and Methods: The 100 soil samples were collected from mentioned regions in various seasons of the year. 150 different Actinomycetes isolates were obtained. These isolates extensively studied for their in vitro ANTI-MICROBIAL ACTIVITY against Gram-positive and Gram-negative bacteria through two steps: primary screening, secondary screening.Results: Twenty isolates showed a strong activity against pathogen bacteria. The results indicated that obtained isolates with an inhibition zone of ³ 10mm were highly resistant against Staphylococcus aureus, Escherichia coli, and Proteus vulgaris. These isolates were identified as Actinomycetes. Morphological and biochemical tests were done for distinguishing of samples. The strains of Actinomycetes were determined following the directions given in the probabilistic identification matrix of Williams and Bergey`s Manual of Systematic Bacteriology. Results obtained from the BIOCHEMICAL ANALYSES including determination of 18 characteristics proved that 8 of strains were in similar group whereas three strains and one strain differed among each other. First group was determined as STREPTOMYCES family with different species.Conclusion: Our studies showed that soil samples of Azarbaijan regions of Iran have Actinomycetes diversity.
