Antimicrobial Potentials of Phyto-synthesized Silver Nanoparticles from Laurus nobilis L.

Abstract

Silver nanoparticles (AgNPs) are popular consumer product additives due to their well-known antimicrobialproperties. Nowadays, their usage has increased after the emergence of green synthesis method with lesstoxicity than conventional methods. In this study, we aimed to reveal the antimicrobial potential of phytosynthesized AgNP by Laurus nobilis L. extracts against different Gram-positive, Gram-negative bacteriaas well as Candida albicans ATCC 10231. Phyto-synthesized AgNPs were characterized by scanningelectron microscopy, zeta size-potential analysis, UV-Visible spectroscopy and FT-IR analysis. The resultsshowed that the size of AgNP was 50 nm and coated by phyto-constituents such as phenolic compoundsaccording to FT-IR results. The antimicrobial activity of AgNP was determined by MIC and MBC tests.The results pointed that green synthesized AgNPs are effective against various microorganisms.
