Biosynthesis and characterization of silver nanoparticles using marasmius palmivorus MG717877.1 and their antifungal activity

Abstract

Silver nanoparticles (AgNPs) were produced utilizing Marasmius palmivorus MG717877.1 in the current investigation. The fungal cell filtrate was used to accomplish external production of silver nanoparticles (AgNPs) from silver nitrate (AgNo3) solution. The aqueous silver (Ag) ions in a 1mM AgNo3 aqueous solution were decreased when it was exposed to fungal cell filtrate, resulting in highly stable AgNPs. When challenged with 1mM AgNo3 solution, the fungal biomass acquired AgNPs on its surface, inside the cytoplasmic membrane, and within the cytoplasm in 72 hours. UV was used to characterize the AgNPs that had been produced. For M.palmivorus MG717877.1, the greatest absorbance of AgNPs was recorded at 400nm in the visible spectrum. Furthermore, the FTIR and SEM analyses of silver nanoparticles on these fungus were used to characterize silver nanoparticles. In addition, we tested the antifungal activity of M.palmivorus MG717877.1 at various concentrations, including 25, 50, 100, and 150 mg/ml. The findings revealed that silver nanoparticles produced in a concentration-dependent manner have strong antifungal activity on isolates. At 150 mg of AgNPs, the highest decrease was seen for this isolate.
