Abstract

The present work investigates the green synthesis of copper nanoparticles (CuNPs) by Fusarium incarnatum isolated from barite mine-contaminated soils, their physicochemical characterization, and their impact on soil exoenzyme dynamics. Nanoparticles were characterized by UV–visible spectroscopy, dynamic light scattering (DLS), zeta potential analysis, FTIR, SEM-EDX, and TEM. Application of these CuNPs to contaminated soils influenced the activity patterns of key exoenzymes in a time- and dose-dependent manner. Results underline the potential of mycogenic CuNPs in the enhancement of soil biochemical functioning and possible remediation of polluted soils.

Keywords: Fusarium incarnatum, copper nanoparticles, soil exoenzymes, nanotechnology, bioremediation, barite mine soil
