# Antibacterial and Antifungal Activities of Musa balbisiana Parts

## TL;DR

This study shows that parts of Musa balbisiana, especially the seeds, have strong antibacterial and antifungal properties, particularly against certain bacteria and molds.

## Contribution

The study identifies the seed part of Musa balbisiana as having the highest antibacterial and antifungal activity among its parts.

## Key findings

- Musa balbisiana seed samples showed the strongest antibacterial effect in both MIC and MBC assays.
- Seed samples also demonstrated the highest antifungal activity against Aspergillus niger and Aspergillus flavus.
- The antibacterial and antifungal effects of Musa balbisiana parts were concentration-dependent.

## Abstract

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.

The antibacterial and antimould activities of Musa balbisiana parts were concentration‐dependent. Seed sample indicated the highest ability to have both studied bioactive properties among the six selected parts. M. balbisiana parts pose potential antibacterial via two antibacterial activity assays of (MIC and MBC) on four investigated bacteria (Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Salmonella enterica). The samples could inhibit both Aspergillus niger and Aspergillus flavus, with the inhibition ability of A. niger being better than A. flavus.
