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 carotenogenesis by yeasts of the genus Rhodotorula of various strains. Such indicators as morphometric characteristics of cells, the amount of accumulated carotenoids, the ratio of budding and dead cells in the nutrient medium during cultivation, the ratio of optical density and number of cells, and the forms of carotenoids contained in cells 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 the biosynthesis of carotenoids; â Inoculate from test tubes with slant agar with museum strains on simulat-ed dense nutrient media; â Analyze the cultural characteristics of grown colonies; â Investigate the morphological and physiological properties of grown yeast cultures of different strains; â Transfer yeast of different strains from solid nutrient medium to liquid nu-trient medium for observation and analysis of carotenogenesis; â To evaluate the accumulation of carotenoids by the yeast Rhodotorula dur-ing cultivation according to a periodic scheme. The objects of the study were pure cultures of the yeast 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: morphometric characteristics of cells, the amount of accumulated carotenoids, the physiological state of cells in the nutrient medium during cultivation, the ratio of optical density and cell number, and the forms of carotenoids contained in cells. The study showed that the enrichment of the nutrient medium with addition-al sources of nitrogen increases the size of cells, accelerates the growth and re-production of yeast and increases the amount of accumulated carotenoids. When writing the literature review, the following databases were used: eLI-BRARY.RU, Scopus, RNL, ScienceDirect, CyberLeninka, ResearchGate, Wiley Online Library. Statistical processing of experimental data was carried out using the Mi-crosoft Word, Microsoft Excel software package.
