description: The strains of the used yeasts of the genus Rhodotorula â Rhodotorula sp.1025, Rhodotorula rubra 266, Rhodotorula roseum â were obtained from the All-Russian Collection of Agricultural Cultures of the Research Institute of Agri-cultural Microbiology. This work is devoted to the study of the influence of various physical and chemical factors on the growth, development and accumulation of biomass by yeasts of the genus Rhodotorula. Such indicators as cell size, amount of accumu-lated nutrients, increase in the number of cells during cultivation, specific culture growth rate, biomass doubling time were considered. To achieve this goal, the following tasks were solved: â To study literary sources on the research topic; â Based on literature data, simulate nutrient media to analyze the effect of chemical composition on biomass accumulation; â Inoculate from test tubes with museum strains on a slanted nutrient medi-um on simulated dense nutrient media; â Analyze the cultural characteristics of grown colonies; â To study the morphological and physiological properties of grown yeast cultures of different strains; â Transfer yeast of different strains from a dense nutrient medium to a liquid nutrient medium for biomass accumulation; â To assess the growth parameters of the yeast strain Rhodotorula during cultivation according to a periodic scheme. The objects of the study were pure cultures of Rhodotorula sp.1025, Rhodotorula rubra 266, Rhodotorula roseum. Experimental research work was carried out in the scientific microbiological laboratory of the Higher School of Biotechnology and Food Production of Peter the Great St. Petersburg Polytechnic University at the Institute of Biomedical Systems and Biotechnologies. The parameters analyzed were: cell size, amount of accumulated nutrients, increase in the number of cells during cultivation, specific culture growth rate, bi-omass doubling time. In the course of the study, it was shown that modeling the nutrient medium with peptone increases the biomass growth rate, size, generation time, and the amount of accumulated nutrients in the cells. When writing the literature review, the following databases were used: eLI-BRARY.RU, Scopus, RNL, ScienceDirect, CyberLeninka. Statistical processing of experimental data was carried out using the Mi-crosoft Word software package.
