Antibacterial and Antifungal Activities of Musa balbisiana Parts

Musa balbisiana parts contain various secondary metabolites with significant biological activities, including antibacterial and antifungal properties. This study aimed to evaluate the antibacterial properties of different parts of M. balbisiana against four selected strains with two positive-gram (Staphylococcus aureus, Bacillus subtilis) and two negative-gram (Escherichia coli, Salmonella enterica) as well as the antifungal ability of two strains of Aspergillus niger and Aspergillus flavus of M. balbisiana parts. The results showed that M. balbisiana parts reveal potential antibacterial and antifungal activities. The investigated samples inhibit positive-gram bacteria better than negative-gram bacteria. The seed sample demonstrated the strongest antibacterial effect compared to other parts in both MBC and MIC assays. Moreover, the seed sample also indicated the highest anti-mold ability on A. niger and A. flavus among the six investigated parts. The findings offer the platform for further applied studies using these parts of M. balbisiana, especially the seed sample in antibacterial and anti-mold products.
