Title

Antibacterial activity of a new species of Streptomyces and optimization its antibacterial compounds

Pages

  1128-1137

Abstract

 Streptomyces are capable of producing secondary metabolites including antibiotics and the main environment of these microorganisms is soil. The purpose of this study was to isolate and evaluate Streptomyces producing antibacterial compounds from different east parts of Gilan province and optimizing antibacterial compounds produced by them. After isolation and purification of Streptomyces, its antibacterial activity against Pathogenic microorganisms including Micrococcus luteus PTCC 1408, Bacillus cereus PTCC 1154, Staphylococcus aureus PTCC 1189, Pseudomonas aeruginosa PTCC 1310, Salmonella typhi PTCC 1609 and Proteus mirabilis PTCC 1776 was investigated. Streptomyces was identified based on morpholigaical, biochemical, physiological, 16SrRNA gene sequencing and Phylogenetic analysis. Optimization of various factors in the content of production of antibacterial compounds was investigated. In this study, 16SrRNA gene sequencing revealed that the isolate belonged to Streptomyces genus and with the highest similarity (95. 70%) to Streptomyces malachitospinus indicating significant differences at species level and it can be introduced as a new species. This isolate showed significant activity against Pathogenic microorganisms. The optimum culture medium, pH, temperature, carbon and nitrogen sources and incubation time for the maximum antibacterial compounds production were ISP2, 7, 28° C, glycerol, yeast extract and 7 days, respectively. The results show that the soils of the eastern regions of Gilan province are a rich source of antimicrobial compounds, which due to the resistance of the Pathogenic microorganisms to antimicrobial drugs, is essential for the production of antimicrobial compounds from natural origin.
