Antimicrobial Effects of Silver Nanoparticles Synthesized by Fatsia japonica Leaf Extracts for Preservation of Citrus Fruits.

Due to their potent antimicrobial activity, silver nanoparticles (AgNPs) synthesized by biomass might be promising in food preservation, whereas effects of AgNPs on Penicillium italicum-induced rot of Citrus fruits have not been investigated. In this study, a novel AgNPs biosynthesis method was developed based on Fatsia japonica leaf extracts. It was revealed that concentrations of leaf extracts, AgNO and NaCl affected AgNPs yields and particle sizes obviously.
