STUDYING OF THE INFLUENCE OF NANOPARTICLES TIO2 AND AL2O3ON BACTERIA PSEUDOMONAS FLUORESCENSAND BACILLUS MUCILAGINOSUS

The using of nanomaterials and nanotechnologies is one of the mostperspective directions of the XXI century. Taking into account the fact thatnanomaterials will be widely used in different spheres (including medicine) in the future,it is very important to reveal their possible risks already today. Methods of biotesting areones of the methods of studying the influence of different factors and substances on livingorganisms. It was studied the influence of nanoparticles TiO2 (5, 50 and 350 nm) andAl2O3 (7, 70 nm and 4 microns) on bacteria Pseudomonas fluorescens AP-33 andBacillus mucilaginosus В-1574. The experiments showed that bacterial test cultures arethe most sensitive to disperse system of nanoparticles TiO2 with the size of 5 nm anddisperse system of nanoparticles Al2O3 with the size of 70 nm and 4 microns.
