Anti Microbial Activity of Musa sapientum Mediated Copper Nanoparticle against Oral Pathogens: An In-vitro Study

Background: Musa sapientum is a useful medicinal plant from the Musaceae family. Copper nanoparticles with a high surface to volume ratio can also be used as antifungal and antibacterial agents. The aim of the study is to access the antimicrobial activity of musa sapientum mediated copper nanoparticle against oral pathogens

Materials and Methods: Plant extract was prepared by 1g of musa, was weighed aseptically and then dissolved in 100 ml of distilled water. Then the solution is boiled for about 5 minutes at a temperature of about 60-80 degree Celsius and then allowed to cool down followed by filtration of extract. The copper solution was prepared by dissolving 20 millimolar of copper sulphate in 80 ml of distilled water followed by 20 ml of plant extract and then the mixture is placed in the shaker for the synthesis and then allowed to mix for about 1 hour then the first reading was taken using UV spectrum and noted down. Antimicrobial activity was done against the strain of S. aureus, S. mutans, E. faecalis. Muller Hinton agar was utilised for this activity to determine the zone of inhibition different concentrations were loaded in the plates and incubated for 24 hrs 37 degree celsius after the incubation time the zone of inhibition was measured. Antifungal activity of zinc oxide nanoparticles was done against the strain Candida Albicans.

Results: For the study, descriptive statistics was used. For 100 μL concentration 11 mm zone of inhibition was seen when compared to the standard drug Amoxyrite which had a zone of inhibition of 36mm, which means that the antimicrobial activity was low in case of E. Faecalis. In C. Albicans, at 100μL concentration 14mm zone of inhibition was seen, but the standard fluconazole had only a zone of inhibition of 10mm, which means antimicrobial activity was good in case of C. albicans which showed more zone of inhibition. For S. aureus, at 100μL 13mm zone of inhibition was seen, the standard value showed 28mm zone of inhibition which means there is less zone of inhibition when compared to standard drug. For S. mutans, at 100μL concentration 18mm zone of inhibition was seen and when compared to the standard value which was 23mm which showed poor antimicrobial activity.

Conclusion: The research concludes that musa sapientum mediated copper nanoparticles showed a moderate antimicrobial activity against the pathogens Streptococcus mutans, Staphylococcus aureus, Enterococcus faecalis and Candida albicans.
