The effect of aqueous and alcoholic extracts of pomegranate peel as a growth inhibitors of Pseudomonas aeruginosa in vitro

Abstract

Aim of this research is to study the effect of pomegranate peel watery and alcoholic extracts against Pseudomonas aeruginosa growth with four concentrations (25, 50, 75, and 100) mg /ml by using agar well diffusion method. The results showed an inhibitory effect which increased with the increasing of the concentration and the type of solvent the bacteria was more sensitive to alcoholic extract concentrations compared with the same concentrations of aqueous extracts It was observed that the effect of differing diameters inhibition of concentrations where the largest diameters inhibition when we focus on 100 mg/ml (37± 2 mm) and (35 ±1.34mm) for extractors alcoholic and water, respectively, and less value Descending to (25)mg/ml which was less effecting against the growth of bacteria by (22±1.2) and (19±0.0) of alcoholic and watery extractors, respectively.
