Kharchenko Y. The use of Saccharomyces cerevisiae yeast for the production of silver nanoparticles

The biological method of synthesis allows obtaining silver nanoparticles (AgNPs) of different shapes and sizes, which is achieved by different conditions of biosynthesis, such as a change in temperature, pH, cultivation time, concentration of silver nitrate, etc. It should be noted that the production of AgNPs using microorganisms is environmentally friendly and economically beneficial, since there is no need to use toxic and expensive materials used in the chemical and physical methods of nanoparticle synthesis. To date, a number of biological (antibacterial, antifungal, antiviral, antitumor effects) and physicochemical properties of biogenic silver nanoparticles have been established, allowing them to be used in medicine, food industry, agriculture, chemical and petrochemical industries, electronics and other industries. The greatest practical interest for the biosynthesis of silver nanoparticles is caused by yeast, in particular Saccharomyces cerevisiae, which is one of the most studied and widely used microorganisms in industry. Therefore, the dissertation work is devoted to the study of the possibility of using the yeast S. cerevisiae for the biogenic synthesis of silver nanoparticles and the study of their antibacterial and antiadhesive activity.
