Detection of antimicrobial activity of banana peel (Musa paradisiaca L.) on Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans: An in vitro study

Abstract

Introduction and Aim:Banana is used widely because of its nutritional values. In past, there are studies that show banana plant parts, and their fruits can be used to treat the human diseases. Banana peel is a part of banana fruit that also has the antibacterial activity against microorganisms but has not been studied extensively. Since, there are no studies that relate the antibacterial activity of banana peel against periodontal pathogens. Hence, the aim of this study is to determine the antimicrobial activity of banana peel extract on Porphyromonas gingivalis (P. gingivalis) and Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans).Material and Methods:Standard strains of P. gingivalis and A. actinomycetemcomitans were used in this study which was obtained from the in-house bacterial bank of Department of Molecular Biology and Immunology at Maratha Mandal's Nathajirao G. Halgekar Institute of Dental Sciences and Research Centre. The banana peel extract was prepared, and the antibacterial activity was assessed using well agar diffusion method and minimum inhibitory concentration was assessed using serial broth dilution method.Results:In the current study, both the tested microorganisms showed antibacterial activity. In well diffusion method, P. gingivalis and A. actinomycetemcomitans showed 15 mm and 12 mm inhibition zone against an alcoholic extract of banana peel, respectively. In serial broth dilution method P. gingivalis and A. actinomycetemcomitans were sensitive until 31.25 μg/ml dilutions.Conclusion:From results of the study, it is suggested that an alcoholic extract of banana peel has antimicrobial activity against P. gingivalis and A. actinomycetemcomitans.

TLC‐bioautography identification and GC‐MS analysis of antimicrobial and antioxidant active compounds in Musa × paradisiaca L. fruit pulp essential oil

“…The antimicrobial activity of banana peel might be due to the presence of bioactive compounds such as vitamin A, vitamin C, gallocatechin, vitamin E, vitamin B6, α‐sitosterol, malic acid, succinic acid, palmitic acid, magnesium, phosphorus, potassium, fiber, iron and fatty acids, whereas the antioxidant activity is due to the presence of gallocatechin . The fruit is also used as antimicrobial, antioxidant, antihyperlipidemic, antihyperglycemic, aphrodisiac, hepatoprotective, diuretic, antioxidant, and antiurolithiatic activity …”

“…As compared to other parts, the banana fruit pulp is the richest source of sugar, which usually favors the microbial growth. However, a negligible growth of microbes in banana is strong evidence of potent/broad‐spectrum antimicrobial agents present in the banana fruit . Though, traditionally as well as practically no microbial growth was found upon storage.…”

“…Musa paradisiaca species also demonstrates anti-bacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus [17] and anti-coccidial activity in chickens [30]. In addition, banana peel extracts show anti-microbial activities against P. gingivalis and A. actinomycetemcomitans [31]. Interestingly, Musa paradisiaca may also offer some protection against snake venom toxicity [32].…”

PHYTOCHEMICAL SCREENING, ANTIFUNGAL AND ANTIBACTERIAL ACTIVITIES OF Musa acuminata PLANT

“…Grand Nain showed significant activity [6]. An alcohol extract of banana peel of Musa paradisiaca L. has antimicrobial activity against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans, which is proven through the formation of inhibition zone surround the discs containing the extract [7]. Thus, this study was aims to determine the phytochemical constituents and potential antimicrobial activity of M. acuminata 'Dwarf Cavendish' leaves.…”
