Characterization and Antimicrobial Activity of Silver Nanoparticles Synthesized with the Peel Extract of Mango

Abstract

The green synthesis of silver nanoparticles (AgNPs) from biological waste, as well as their excellent antibacterial properties, is currently attracting significant research attention. This study synthesized AgNPs from different mango peel extract concentrations while investigating their characteristics and antibacterial properties. The results showed that the AgNPs were irregular with rod-like, spherical shapes and were detected in a range of 25 nm to 75 nm. The AgNPs displayed antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), showing a more significant impact when synthesized with 0.20 g/mL of mango peel extract. Therefore, the antibacterial effect of different diluted AgNP concentrations on the growth kinetic curves of E. coli and S. aureus after synthesis with 0.20 g/mL mango peel extract was analyzed. The results indicated that the AgNP antibacterial activity was higher against S. aureus than against E. coli, while the AgNP IC50 in these two strains was approximately 1.557 mg/mL and 2.335 mg/L, respectively. This research provides new insights regarding the use of postharvest mango byproducts and the potential for developing additional AgNP composite antibacterial materials for fruit and vegetable preservation.

Biogenic Preparation and Characterization of Silver Nanoparticles from Seed Kernel of Mangifera indica and Their Antibacterial Potential against Shigella spp.

“…Hence, nanoparticle aggregation was due to the covering of the AgNPs by capping agents, causing them to adhere to each other. Furthermore, the nanoparticles’ sizes increased in conjunction with extract concentrations, causing changes in shape, which can be attributed to the growth rate of crystal nucleus [ 25 ].…”

Green Synthesis and Characterization of Silver Nanoparticles Using a Lythrum salicaria Extract and In Vitro Exploration of Their Biological Activities

“…However, there are several research works that prove the contrary, as in our case. For example, Yage Xing et al obtained better antibacterial activity on S. aureus , compared to E. coli for AgNPs formed using mango peel [ 46 ]. A similar example is that of AgNPs synthetized using olive leaves extract [ 47 ].…”

Phyto-assisted synthesis of zinc oxide nanoparticles using mango (Mangifera indica) fruit peel extract and their antibacterial activity

“…In comparison, the biosynthesized ZnO exhibited more significant activity than chemically synthesized ZnO nanoparticles (data not shown), indicating a synergistic effect of ZnO nanoparticles with organic molecules left on the ZnO nanoparticle surface after biosynthesis. The mechanism of antibacterial activity of biosynthesized ZnO nanoparticles may be attributed to the adherence of nanoparticles onto bacteria's cell walls and disruption of the membrane, which leads to cell lysis [25,32,33].…”

“…Mango fruit is rich in organic molecules such as phenolics and flavonoids, which can be used as a potential source of antioxidant compounds [29][30][31]. Studies have been conducted on applying mango fruit peel extract as a reducing and capping agent for the biosynthesis of TiO2 and silver (Ag) nanoparticles [11,12,32]. Herein, we report a facile, inexpensive, and green method for preparing ZnO NPs utilizing mango fruit peel (MFP) aqueous extract.…”
