Nanotechnology is rapidly progressing and has been proven to be more successful than traditional water treatment methods, allowing for the safe use of unusual water sources. Fungi are more versatile in terms of proliferation and metal tolerance than bacteria. The goal of this study is to show that silver nanoparticles may be synthesised outside of the cell. Penicillium Citreonigum Dierck and Scopulaniopsos brumptii Salvanet-Duval are two filamentous fungi found in Lake Michigan. Burullus uses UV–vis spectroscopy and transmission electron microscopy to study biosynthesized nano-silver particles (TEM). Fourier transform infrared (FTIR) analysis was used to identify a functional group of protein molecules surrounding AgNPs. At two doses (550.7 and 676.9 mg/l), test the bactericidal effectiveness of biosynthesized silver nanoparticles, as well as their long-term interactions with bacteria (15, 60 and 120 min). To eliminate dangerous microorganisms in contaminated water, polyurethane foam was employed as a silver transporter and nano-silver solution. The AgNPs have exceptional antibacterial efficacy against both Gram-positive and Gram-negative bacteria.
