"Green chemistry" is a simple and easily reproductible method that provides nanoparticles characterized by better stability good dispersion in an aqueous solution. Nanoparticles can be synthesized algae, bacteria, fungi, plant extracts. Ganoderma lucidum commonly used medicinal mushroom with distinctive biological properties, such as antibacterial, antifungal, antioxidant, anti-inflammatory, anticancer, etc. In this study, mycelial extracts of were to reduce AgNO3 form silver (AgNPs). The biosynthesized UV-visible spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) analysis. maximum UV absorption was obtained at 420 nm, which represents the specific surface plasmon resonance band for nanoparticles. SEM images showed particles predominantly spherical, while FTIR spectroscopic studies illustrated presence functional groups support reducing ion Ag+ Ag(0). XRD peaks ratified AgNPs. antimicrobial effectiveness tested against Gram-positive Gram-negative bacterial yeasts strains. effective pathogens, inhibiting their proliferation, thus risk environment public health.
