The aim of the present study was to examine the antibacterial activity of methanol extract of pomegranate peels against some Gram positive and negative bacteria. The antibacterial activity was evaluated using both agar-diffusion method and minimum inhibitory concentration (MIC). With the exception of Streptococcus faecalis and Salmonella, all of the bacteria showed sensitivity to methanol extracts of pomegranate peel The Minimum Inhibitory Concentration varied with Streptococcus salivarius and Bacillus subtilis having the lowest MIC (1mg/ml) while Streptococcus faecalis and Salmonella where more resistant, having MICs of 4 and 8 mg/ml respectively. https://www.biotech-asia.org/vol9no1/antibacterial-activity-of-methanol-extract-of-pomegranate-punica-granatum-l-peels/ Pomegranate peels; Punica granatum; opportunist infections; antibacterial activity
