Biogenic synthesis of zinc oxide nanoparticles using Citrus limetta peels and their antimycotic potential against Ganoderma lucidum
摘要
Utilizing waste Citrus limetta peel aqueous extract for the synthesis of zinc oxide nanoparticles (ZnO NPs) with antimycotic potential is an ecofriendly approach. Green ZnO NPs were reported to have a characteristic UV- Vis peak at 389 nm. X-ray diffraction (XRD) analysis estimated the crystallite size of the ZnO NPs to be 15.37 nm, and Scanning Electron Microscopy (SEM) revealed flake shaped morphology. Fourier Transform Infrared Spectroscopy (FTIR) analysis indicated several functional groups like ˗C = O, ˗C˗C, ˗C˗O, etc., which were associated with amides, anhydrides, ethers and alcohols attached to the ZnO NPs. These ZnO NPs were determined to inhibit growth of Ganoderma lucidum by about 85.70% at a lower concentration of about 500 µg/mL. The eco-friendly and cost-effective nature of these ZnO NPs coupled with their promising growth inhibiting activity against G. lucidum, makes them a valuable and sustainable approach for addressing root rot infections.
