Green Synthesis of Silver Nanoparticles by and its Function Against and Fungi.

(NPs) can be produced by various methods such as physical and chemical processes. However, environmentally friendly ways are increasingly requested. In this research, (Ag-NPs) were produced by and its antifungal effect on and was investigated. Nanoparticles were produced by silver nitrate salt and native to Isfahan city. In order to optimize the synthesis conditions, optimization of some factors such as volume, concentration, time, temperature, and pH of the extract was performed. The structural and physical properties of NPs were determined by spectrophotometer, XRD, FTIR FESEM, SEM, and TEM microscopy. For the study of the inhibitory effect of NPs on and growth, the fungi were cultured in media containing various concentrations of NPs from 50 to 1500 ppm. Then, the colony diameter was measured for over 10 days and the growth inhibition percentage was estimated. For statistical analysis, the 600 Mann-Whitney tests have been applied.The NPs were produced after mixing the powdered fungal mass and silver nitrate salt in optimum conditions which were 2 mM of salt, triple fungal mass volume proportion relative to the salt, pH of 9, and temperature of 28 °C. The existence of a peak at 420 nm in FTIR was due to nanoparticle production. Based on the XRD, the synthesized NPs had suitable properties similar to the standard NPs reported in the studies. Images from TEM, SEM, and FESEM microscopes displayed uniform NPs in variable sizes between 25 and 100 nm. According to the results, the maximum growth inhibition percentage of Ag-NPs on was approximately 60% at 1500 ppm, and 88% on at 800 ppm. Biosynthesized Ag-NPs with have desirable structural traits and can inhibit the growth of and at significant levels.
