Biosynthesis, characterization and antibacterial activity of silver nanoparticles by soil fungi Pencillium sps
Keywords:
Silver nanoparticles, Biological synthesis, Characterization, Antibacterial activityAbstract
In the present days microbial synthesis of nanoparticles is an eco-friendly green chemistry approach that correlates with nanotechnology and microbial biotechnology. In this study exposure of fungal biomass to aqueous 1Mm AgNO3 solution resulted in the reduction of the metal ions by the nitrate reductase enzyme present in the fungal cell wall membranes and formation of silver nanoparticles. Synthesized silver nanoparticles were characterized using UV-visible spectroscopy, SEM, TEM and FTIR analysis and size and shapes were determined. The synthesed silver nanoparticles were exhibited an excellent antibacterial activities against both gram negative and gram positive pathogenic bacterial strains which causes the diseases in human beings.
