description: This research work is devoted to the study of the antimicrobial properties of natural rubber and synthetic cis-isoprene rubber in relation to microorganisms Escherichia coli and Candida tropicalis. Tasks that were solved in the course of the study: â to determine the objects of study: rubbers, microorganisms; â to prepare nutrient media that meet the requirements of microorganisms; â conduct thermostatic control of the studied microorganisms; â prepare acetone extracts of rubbers; â to identify the antimicrobial activity of drugs using the disk-diffusion method; â calculate the probabilities of manifestation of biological activities of the compounds that make up the studied synthetic rubber using the PASS online web service. The objects of the research are natural rubber, synthetic cis-isoprene rubber. The work was carried out on the basis of the laboratory of microbiology of the GSB&amp;FS of the IBS&amp;B. The analyzed parameter of the biological activity of the studied rubbers was the indicator of antimicrobial activity. As a result of the study of the antimicrobial activity of acetone extracts of rubbers by the disk-diffusion method, it was demonstrated that natural rubber extract exhibits the most toxic properties against E. coli bacteria and yeast-like fungi C.Â tropicalis. No antimicrobial activity of synthetic rubber against yeast C. tropicalis was found. The calculation using the PASS Online web service showed that the substances used in the production of synthetic rubber and some products include the presence of biologically active substances â from 20 to 58 types of activity.
