Antimicrobial Activity of Musa acuminata Peel Extract against Gram-Positive Bacteria

Abstract

Particular communities are discarding banana (Musa acuminata) peels as household and industrial food waste. It is high in nutritive value and a healthy source of food to consume. This study aims to evaluate the antimicrobial activity of M. acuminata peels against four types of Gram-positive bacteria, namely, Bacillus cereus, Staphylococcus aureus, Streptococcus pneumoniae and Streptococcus pyogenes. The extract of M. acuminate peel was prepared using a soxhlet apparatus for ethanolic extract and rotary evaporator to concentrate the ethanolic extract. Antimicrobial activity was carried out on the extract using agar disc diffusion technique; the inhibitory zones were recorded in millimetres. Results showed that the disc diffusion method of ethanolic extract of M. acuminata peel was not effective against all the Gram-positive bacteria strains. This result indicated that M. acuminata peel did not pose any potential antimicrobial effect against Gram-positive bacteria. However, further study should be carried out using different extraction method and concentration in order to evaluate antimicrobial activity.

Antimicrobial properties of marine fungi from sponges and brown algae of Mauritius

“…Sterile filter paper discs (6 mm) containing 10 µl of the fungal extracts were placed onto the agar plates. The plates were incubated at 37°C for 24 h and the zone of inhibition was measured to the nearest mm (Subramaniam et al 2020 ).…”

Antibacterial Activity of Fruit Peels Extracts Against Pathogenic Bacteria

“…who revealed that banana peel extract has the best antimicrobial activity and preservatives of banana peel extract are believed to be associated with phytochemical components of it, like phenolic and tannins as reported by [17]. However, the result was not the same with [13] reported that banana peel extract was not effective against all strains of Gram-positive bacteria. Also, [32] reported that banana peel extract is only effective against Agrobacterium tumefaciens, Other bacterial strains, on the other hand, demonstrated resistance to the extract-treated wood.…”

“…However, it is not further involved in remarkable industrial applications, although it contains many beneficial compounds, such as carotenoids, alkaloids, steroids, saponin, flavonoids phenolics, glycosides, amines, vitamins, fibers, minerals and carbohydrates [12]. Banana peels were used as traditional medicine in diarrhea, dysentery, enteric infections, diabetes, promote wound healing, primarily from burns, and aid in the treatment or prevention of a wide range of illnesses [13].…”

Phytochemical screening and in vitro evaluation of the antiarthritic activity of Nigella sativa L. seeds extracts

“…These molecules, although effective from 15 to 20% [2]. The very wide uses of medicinal plants for centuries by humans for treating various common pathologies prompted researchers to study the activities and pharmacological properties of different plant metabolites to confirm its properties on the one hand and on the other hand to identify the active ingredients at the origin of these virtues and consequently the use of these natural medicines wisely in primary care systems [3][4][5]. Some plants can be a major source of drugs due to their richness in secondary metabolites, these make and remain the subject of many researches, in particular the research of new natural constituents such as phenolic compounds, saponosides, alkaloids and essential oils [6,7].…”
