Mushrooms (Agaricus bisporus) mediated biosynthesis of sliver nanoparticles, characterization and their antimicrobial activity

In this paper we report an eco-friendly route for the synthesis of sliver nanoparticles using Agaricus bisporus (white button mushroom) extract. The synthesized silver nanoparticles were confirmed and characterized by UV-Visible spectrum of the aqueous solution containing silver ions showed a peak at 420 nm corresponding to the surface plasmon absorbance of silver nanoparticles. Transmission Electron Microscopy (TEM) micrographs showed the size of silver nanoparticles and were measured in the range of 8-50nm, Fourier Transform Infrared Spectroscopy (FTIR) spectrum detection of analysis showed peaks between 500-4000 cm(-1) confirmed the presence of proteins, carbonyl groups, esters and carboxylic acids for the synthesis and stabilization of silver nanoparticles. X-ray diffraction (XRD) spectrum of the silver nanoparticles exhibited 2 theta values corresponding to the silver nanocrystal. Further, the antibacterial activity of synthesized silver nanoparticles showed effective inhibitory activity against pathogens and nonpathogenic bacterial strains vis, Escherichia coli, Staphylococcus sps, pseudomonas sps, and Bacillus sps.
