The work is devoted to research on the selection of peptone for the optimization of the nutrient medium for the antimicrobial activity by the agar diffusion method of neomycin (framycetin), which have a similar chemical structure. The paper substantiates the relevance and importance of developing a formulation, selecting the optimal composition (ingredients), the quantitative ratio of ingredients, the pH of the medium, compliance of the proposed nutrient media with the State Pharmacopoeia of the Russian Federation and the European Pharmacopoeia for the standardization of antibiotics. The aim of the work was to study the components of the nutrient medium in comparison with the pharmacopoeial standards recommended for determining the effectiveness of antibiotics. It is shown that for carrying out microbiological tests in the standardization of antimicrobial drugs, the nutrient medium is the main one, and the correctness and accuracy of the interpretation of the research results depend on their quality. The experiment studied four brands of dry peptone and broth from different manufacturers – LLC NITSF and FBUN GNTs PMB (Obolensk) when working with the test strain of the spore culture Bacillus subtilis ATCC 6633. An optimal nutrient medium is proposed, the composition and conditions of its preparation are selected. To determine the antimicrobial activity of framycetin by the agar diffusion method, a developed medium for determining the effectiveness of neomycin when working with the spore-forming form of the test strain Baccillus subtillis ATCC 6633 is proposed.
