Cobalt ferrite magnetic nanoparticles (MNPs) were prepared by co-precipitation being further electrostatically stabilized in solution (particularly used in experimental cancer treatment through hyperthermia). We focused on the biological impact of MNPs following their release in the environment mainly the oxidative stress induced in some microorganisms: cellulolytic fungi: Phanerochaete chrysosporium and Trichoderma viride (able of degrading cellulose waste). XRD provided typical spinel structure, SEM data revealed a 45 nm physical diameter, magnetometric investigation evidenced ferrimagnetic properties overlapped onto superparamagnetic ones, while dynamical analysis of particle movement in diluted solution indicated a 65 nm hydrodynamic average diameter. Increased activity of superoxidedismutase (with about 12%, p
