Fruit peels have been a valuable source for maintaining human health. The use of fruit peels
extracts for antimicrobial properties can be of great significance in therapeutic treatments. This
study aimed to evaluate the antibacterial activity of banana s peel. The antibacterial effect of
aqueous extracts of fresh yellow banana peels against 2 Gram-positive and 4 Gram-negative
bacterial and one yeast isolates, including S. aureus, S. pyogenes, E. aerogenes, K. pneumoniae,
E. coli, M. catarrhalis and candida albicanis, was carried out by the well-agar diffusion method.
The water extract of fresh banana peel showed a various inhibitory effect against various
microbial isolates. Highest inhibitory effect against both M. catarrhalis and S. aureus with 30
mm inhibition zone, followed by S. pyogenes, E. aerogenes and K. pneumoniae with no effect
against E. coli and candida albicanis. Aqueous extracts of fresh yellow banana peels could be
considered as a good antibacterial agent against both Gram positive and negative bacteria to
replace the synthetic medicines in tratment of diseases caused by these bacteria.
