Abstract
We report extracellular biosynthesis of silver nanoparticles by Fusarium solani which isolated from wheat grains when challenged with 1mM silver nitrate (AgNO3). The formation of nanoparticles was characterized by color change followed by UV-Vis spectrophotometric analysis, which showed a peak at about 415nm, which is very specific for silver nanoparticles. Silver nanoparticles amount were 55% showed by Energy Dispersive Spectroscopy (EDS). Transmission Electron Microscopy for particles size and morphology. In addition, in this research we study effect of silver nanoparticles on % fungal frequency at different concentrations was analyzed in PDA, in all cases, fungal frequency % were recorded zero at 4%. While no effective noticeable with treatment at 1% of AgNPs against all fungi. On the other side, data obtained that treatment with silver nanoparticles on % fungal frequencies at different concentrations were the best with compared Non-Surface sterilization or Surface sterilization with sodium hypochlorite.
