ESTIMATION OF THE EFFECTS OF CHITOSAN-IRON NANOCOMPOSITES DEVELOPED BY DIFFERENT PROCESSES ON RH. GRACILIS CNMN-Y-30 YEAST

Abstract

Abstract. The paper provides information on the estimation of the effects of iron chitosan nanocomposites, elaborated by different procedures on pigmented yeast Rh. gracilis CNMN-Y-30. It was found that the initial amount of chitosan, the concentration of Fe3O4 nanoparticles and the volume of nanocomposite used for growing yeasts are the main factors that influence the efficiency of chitosan-iron nanocomposites. Microbiological indices adequately reflect the effects of chitosan-iron nanocomposites in the process of evaluating the action of nanocomposites obtained by different processes on the representative yeast Rh. gracilis CNMN-Y-30 and it is recommended to test the degree of influence of the nanocomposite. This information can be used by specialists in the food industry, microbiology, medicine, cosmetology, environmental protection, etc., where nanocomposites have applications.
