Abstract
The present study was conducted with a view to evaluate the antibacterial potential of Pseudomonas syringae used in Iran against plant pathogenic bacteria. For evaluation of antibacterial effects of the methanol, disc diffusion method through the measurement of the inhibitory zone diameter was used. The antimicrobial methanol extract in three concentrations (20, 40, 50 mg/ml) were tested on Escherichia coli, Rathayi bacter tritici, Xanthomonas campestris and Pseudomonas syringae. Results of research showed that both concentrations had a positive effect on aforementioned bacteria. It also revealed higher concentration had direct influence on the size of inhibitor zone. In 50 mg/ml concentration, the maximum zone of inhibition (ZOI) was 23.98 mm in Pseudomonas syringae. The acceptable minimal inhibitory concentration (MIC) and minimum lethal concentration (MLC) were 10 mg/ml and 22mg/ml respectively. The results demonstrate the antibacterial potential of this plant and hence lend support for the use of them to control plant pathogenic bacteria.
