The aim of this study was to estimate the sensitivity of microorganisms, isolated from soil long-term polluted with obsolete pesticides, to magnetite (Fe3O4) nanoparticles and fluorinated dinitroaniline herbicide trifluralin, and to evaluate the inhibition activity of these substances. The response of fungi and streptomyces strains to the presence of magnetite nanoparticles in culture media is individual to each microorganism. For the most of studied microorganisms, the addition of trifluralin to culture media had a growth inhibition effect. An exception was the strain Streptomyces sp. 0412, which growth was stimulated in the presence of xenobiotic. The negative effect of pesticide was reduced, when before the addition to the culture medium the trifluralin was mixed and incubated with magnetite nanoparticles for 1 hour.
