Green Synthesis of Silver Nanoparticles using Pluerotus and its Bactericidal Activity
Silver nanoparticles (AgNPs) were synthesized using oyster mushroom Pleurotus citrinopileatus extract as a reducing agent and aqueous silver nitrate as the precursor. The AgNPs formation was observed as a color change of the mixture from colorless to dark-brownish. The Transmission Electron Microscopy (TEM) and Energy Dispersive X-Ray spectroscopy (EDX) confirmed the size, shape and composition of synthesized materials. Furthermore, UVVIS spectroscopy as well as Fourier Transform Infrared (FTIR) identifies ethylene groups as the reducing agent and capping agent for the formation of the AgNPs. This green synthesis provides a cost-effective, eco-friendly, and clean synthesis route to AgNPs. The colloidal AgNPs showed bactericidal effect against pathogenic bacteria such as Escherichia coli and Staphylococcus aureus.
