Comparison of Musa sapientum (ABB group) cv ‘KLuai Hin’ Peel Extracts for Antibacterial Activity

Abstract

          Musa sapientum (ABB group) cv ‘Kluai Hin’ belongs to the Musacaea Family, which is abundantly found in the southernmost provinces; Yala, Pattani, and Narathiwat. Its fruits are normally processed for various local products while the peel becomes the waste effecting the environment. This study aims to investigate the effects of the aqueous and ethanol extracts of raw and ripe banana peel on the inhibition of three different bacterial species; E. coli ATCC 25922, S. aureus ATCC 6538P, and B. subtilis ATCC 6051 using agar disk diffusion method at the concentration of 50, 100, 150, and 200 mg/ml. The percent yield of crude extract was ranged from 0.42-1.20. The result showed that the aqueous crude extract of raw banana peels at 200 mg/ml can inhibit S. aureus ATCC 6538P and B. subtilis ATCC 6051 at 8.83±0.76 and 10.83±0.76 mm respectively. Therefore, the banana peel extracts can be used in natural antibacterial product which can potentially reduce chemical used and become more environmentally friendly. Moreover, it increases value to the left over material in the future.
