Biomimetic synthesis of AgNPs from Penicillium chrysogenum strain FGCC/BLS1 by optimising physico-cultural conditions and assessment of their antimicrobial potential.

ABSTRACT: Biomimetic synthesis of metal nanoparticles (NPs) is safe and eco-friendly; therefore, find diverse applications. Considering this, the soil fungi Penicillium chrysogenum strain Fungal germplasm collection centre/ BLS1 was isolated, characterized and explored to synthesize extracellular silver NPs (AgNPs) under optimised conditions. The synthesis of AgNPs was investigated using ultraviolet (UV)-visible spectroscopy, Fourier-transform infra-red spectroscopy (FTIR), transmission electron microscope (TEM) and dynamic light scattering (DLS) analysis. Process optimisation exhibited AgNPs synthesis within 8 h using 2 mM AgNO3 at pH 11 and temperature 70°C. TEM analysis revealed polydispersed ellipsoidal shaped AgNPs with average particle size 96.8 nm as measured by DLS. AgNPs showed negat
