Antimicrobial Activity and Minimum Inhibition Concentration of Banana Peel

Abstract

Antimicrobial activity of banana plays a vital role in pharma industries because of its bioactive compounds. Previous research shows that banana plant parts and their fruits can be used to treat the human diseases. Banana peels have antibacterial activity against microorganisms but has not been studied extensively. Banana peels has lots of micro and macro biomolecules, and it is used to resist microbial growth. Plate diffusion method has to identify the zone of inhibition (ZOI), and it shows the capability of banana peel to resist microbes. The aim of this study is to determine the antimicrobial activity of banana peel. Methanolic extract against Serratiamarscens, Pseudomonas aeruginosa, Bacillus subtilis, Shigella flexneri, Vibrio parahaemolyticus, and fungal species like Aspergillus flavus, Trichoderma viride, Candida albicans, Penicillium griesiferum. Zone of inhibition was higher in Bacillus subtilis. This study shows antimicrobial activity of banana peel. Least MIC was 15.6 µg/ml against Shigellaflexneri, and highest MIC was 1000 µg/ml against Serratia marscens.
