Hom Thong banana (Musa sp., AAA group, Gros Michel) peels are inedible food wastes that are readily available and contain promising phytochemical compounds for the elucidation of their antibacterial activities. Hence, the purpose of this research was to study the antibacterial effects of the extracts from unripe Hom Thong banana peel. Two different solvents, 95% ethanol and 100% methanol, were used for the extraction of banana peels and investigated the efficacy of the extracts for the inhibition of three strains of the following bacteria: Escherichia coli ATCC 25922, Salmonella Typhimurium ATCC 13311 and Staphylococcus aureus ATCC 25923. Our results showed that ethanolic extract of unripe Hom Thong banana peel had the ability to inhibit Staphylococcus aureus ATCC 25923 with the inhibition zone diameter of 13.50 ± 1.29 mm while methanolic extract of unripe Hom Thong banana peel did not show antibacterial effects against all of the three strains of bacteria. Determination of the minimum inhibitory concentration (MIC) of the extract that could inhibit the growth of Staphylococcus aureus ATCC 25923 by macro broth dilution techniques followed by the investigation of minimum bactericidal concentration (MBC) on the MHA medium showed the values of MIC and MBC at 10 and 20 mg/ml, respectively.
