Rezumat

The invention relates to biochemistry, in particular to a method for assessing the toxicity of metal oxide nanparticles using yeasts. The method, according to the invention, provides sowing Rhodotorula gracilis CNMN-Y-30 yeast on a nutrient medium YPD, adding metal oxide nanoparticles at a concentration in the range of 0.5...15.0 mg/L, deep culturing for 72 hours, separating the biomass, determining in the biomass the catalase activity and β-carotene content, at the same time the toxicity level of metal oxide nanoparticles is established proceeding from concentrations that provoke a decrease in catalase activity or β-carotene content by 50 %.
