Antibacterial Activity Of Fruit Banana Stone And Mechanism
MetadataShow full item record
Objective: The purpose of this study was to determine the strength of antibacterial activity of the fraction of banana stone and its mechanism. Methods: The antibacterial activity test was performed using the diffusion method by measuring the diameter of the clear zone around the disc paper. Results: The results of antibacterial activity test showed that ethyl acetate fraction was more effective against bacterium Staphylococcus aureus, Staphylococcus epidermidis, and Propionibacterium acnes compared to n-hexane fraction. Conclusion: The resulting cellular metabolite leak showed that cell leakage in the three bacteria due to ethyl acetate fraction had leaked more protein than nucleic acid, while the leakage of more dissolved K+ ion than Ca2 + ions.
