Aim and Background. Silver nanoparticles have antibacterial properties and are used in textile, hygiene, refinement, staining, agriculture and livestock industries. The aim of this study was the production of silver nanoparticles using Fusarium oxysporum and Escherichia coli. Materials and Methods. We used agar diffusion disk for the inspection of antibacterialproperties of nanosilver colloids. The shape and morphology of nanosilver colloids were evaluated by transmission electron microscopy. Results. The presence of nanosilver colloids was confirmed by UV/Vis spectrophotometry. The mean size of nanoparticles produced by F. oxysporum was smaller than those of them in E. coli. Conclusion. Results of the present study showed that the quality of nanosilver colloids from F. oxysporum is better than those of them in E. coli.
