Nanoparticles Nano zero-valent iron (nZVI) Fe0/PVP were prepared by chemical reduction from a ferrous salt-solution in the presence of PVP used as a stabilizer. The resulting nanoparticles were characterized by X-ray powder diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission microscopy (TEM), and FT-IR–spectroscopy. Aqueous colloidal sollution of prepared nanoparticles was used in biotest. The results show that Fe0/PVP nanoparticles can act as both stimulants and inhibitors of mycelial growth. The stimulating effect of Fe0/PVP was observed on three out of five micromycete strains, namely 1LD, 5D and 8D. The growth of the strains Alternaria sp. 4D and P. viride was significantly suppressed in the presence of solution of Fe0/PVP nanoparticles (the inhibition activity was 26.88% and 13.91%, respectively). At the same time, Fe0/PVP nanoparticles stimulated the formation and maturation of micromycetes’ spores. |
