Determination of Antimicrobial Activity of Fruits

The present study was designated to study the antimicrobial activities of aqueous extracts, that were prepared from fresh fruits of Emblica officinalis, Hylocereus undatus,Vitis vinifera, Syzygium cumini and Actinidia deliciosa. The antimicrobial activities of the selected fruit extracts were evaluated, by measuring the zones of inhibition using Agar well Diffusion method, against five species of micro organisms; Pseudomonas aeruginosa, Klebsiella pneumonia, Escherichia coli, Staphylococcus aureus and Candida albicans. The overall result of this study indicated that, the fruits showed different inhibition zones, along with different concentrations and observed that, the effect of fruits against pathogens were concentration dependent. Response against in increase and decrease in concentration was varied, among all the fruits. Fruits might have antimicrobial activity, against different Gram-positive, Gram-negative and yeast pathogens and could be used for prevention of various diseases, caused by these organisms.
