Abstract

Mushrooms have been used by people for centuries for various purposes due to their unique taste, high nutritional content and pharmacological effects. Bioactive components in the structure of mushrooms are an important biological source for the green synthesis of silver nanoparticles (AgNPs) as reducing and stabilizing agents. In this study, AgNPs/Ig were synthesized using the mushroom species Infundibulicybe gibba. The color transformation of the formed nanoparticles from yellow to brown occurred and peaked at 370 nm in the UV–Vis spectrum. The nanoparticles had amorphous shape and their molecular characterization was determined by Fourier transform infrared spectroscopy (FTIR). AgNPs/Ig was much more stable (− 50.02 mV) and its hydrodynamic diameter was much lower (216.50 nm) compared to the mushroom extract. A significant increase in the antioxidant activity (IC50 5.66 mg/ml) and thermal stability of the formed nanoparticles was determined. Lipid peroxidation inhibition of the extract and nanoparticles was measured as IC50 value of 6.75 and 5.51 mg/ml, respectively. In the antimicrobial analysis results, while the mushroom extract did not show any inhibition against the selected microorganisms, AgNPs/Ig showed a low antimicrobial activity. As a result, the synthesis of AgNPs/Ig was carried out through green synthesis, which is environmentally friendly, safe, cost-effective, easy to use and does not contain toxic chemicals, and it has been revealed that AgNPs synthesized using this mushroom species have advantageous potential for use.
