Isolation and Identification of the First Indigenous Bacterial Strain Against Xanthomonas citri subsp.citri Causal Agent of Citrus Canker Disease

Citrus canker bacterial disease is one of the most devastating citrus diseases and including a quarantine disease that severe damage to citrus، which made Iran. Is that why this is necessary to study about inhibition of this disaster. Xanthomonas citri subsp. citri (xcici) is agent of this disease. In recent years، many efforts have been focused on finding antibiotics that bacteria can not be resistant against it. Antimicrobial peptides produced by different organisms، are good candidates for this approach. We were collected soil، water and plant organs samples from variation regions of sistan and balluchestan (up to ten regions) then we moved them to the laboratory under suitable conditions. Lashar DGH2 a new bacteriocin، which is native and is a good candidate for controlling this disease. This bacteriocin is the first world Xanthomonas inhibitory bacteriocin were used against different bacterial strains Xanthomonas and able to inhibit strains of this bacterium in Iran and another countries. It is hoped that، with future research on this bacteriocin and optimization of its inhibitory effect be able an important step in controlling this disease.
