INFLUENCE NANOPARTICLES Fe3O4 AND TiO2 ON GROWTH AND BIOCHEMICAL COMPOSITION OF YEAST STRAIN RHODOTORULA GRACILIS CNMN-Y-30

The present work provides the results of the research of the influence of the inorganic nanoparticles TiO2 and Fe3O4 with the size of 30 nm, in different concentrations, on the growth process and biochemical composition of biomass stalk of the yeast Rhodotorula gracilis CNMN-Y-30. It has been found that nanoparticles at concentrations of 0.5 to 5.0 mg/L did not significantly alter the reproduction of the cells and the productivity of the yeast. The positive effect is manifested by favorable changes in carbohydrate and protein content, at the cultivation in the presence of the nanoparticles TiO2 and Fe3O4. Keywords: nanoparticles, cultivation, yeast cells, productivity, protein, carbohydrates.
