Abstract
The green synthesis of silver nanoparticles (AgNPs) from biological waste, as well as their excellent antibacterial properties, is attracting a lot of attention in the scientific community right now. In this study, AgNPs were synthesised from various mango peel extract concentrations and their characteristics and antibacterial properties were investigated. The AgNPs were irregular, with rod-like, spherical shapes, and were detected in a range of 25 nm to 75 nm. The AgNPs demonstrated antibacterial activity against E. coli and Staphylococcus aureus (S. aureus), with a greater impact when synthesised with 0.20 g/mL mango peel extract. As a result, the antibacterial effect of various diluted AgNP concentrations on E. coli and S. aureus growth kinetic curves after synthesis with 0.20 g/mL mango peel extract was investigated. The results showed that AgNP had greater antibacterial activity against S. aureus than against E. coli, with the AgNP IC50 in these two strains being 1.557 mg/mL and 2.335 mg/L, respectively. This study sheds new light on the use of postharvest mango byproducts, as well as the possibility of developing additional AgNP composite antibacterial materials for fruit and vegetable preservation.
