Evaluation of antibacterial activity of different extracts of Gleditschia caspica against two citrus pathogenic bacteria

Abstract

Secondary metabolites of plant extractions have medicinal properties, antifungal, antibacterial and antioxidant properties. This study aimed to investigate the effect of antibacterial activity of Gleditschia Caspica at two concentration (75 and 100 mg/ml) against Pseudomonas viridiflava and Pseudomonas syringae . The results revealed that all extract methods exhibited significant effects on bacterial growths. It also showed that both concentrations had a positive effect on aforementioned bacteria. It has been proven that the highest impact is at concentrations of 100(mg/ml) with an inhibitor zone of 20 (mm) in Pseudomonas syringae . This study also revealed that methanol extract had minimum inhibitory concentration (MIC) at the concentration of 10 (mg/ml) and minimum bacteria Concentration (MBC) at the concentration of 50 (mg/ml). The results indicate the potential of this plant for controling plant pathogenic bacteria.
