摘要

Interest in the biosynthesis of nanoparticles using biological resources has increased as a result of the growing need for environmentally acceptable nanotechnology. In this work, vermicompost and cultural extracts of Trichoderma species and were used to synthesize copper oxide nanoparticles (CuONPs). The structural, morphological, and optical characteristics of the biosynthesized CuONPs were assessed by means of Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV-Vis spectroscopy. The antimicrobial activity of CuONPs was determined against various fungal pathogens including Curvularia sp., Alternaria sp., Bipolaris sp., Fusarium sp., Helminthosporium sp., and Botrytis sp. Results revealed a significant inhibitory effect, demonstrating the potential of biosynthesized CuONPs as an effective antimicrobial agent. This study highlights the sustainable production of CuONPs and their promising role in combating microbial infections, offering an environmentally friendly alternative to conventional chemical synthesis methods.
