Aim. The aim of the work was to study the possibility of using an environmentally friendly strain of yeast of the genus Rhodotorula for the bioconversion into fodder carotenoid‐containing biomass of the secondary product of processing pea flour into a protein concentrate (whey).Material and Methods. We used a new strain of Rhodotorula mucilaginosa 111 and by‐products of processing pea and chickpea flour into protein concentrates and potatoes into starch (whey). We used standard and special methods for the analysis of serum and microbial‐vegetable concentrate (FMVC) namely: chemical; biochemical; microbiological; and the determination of toxicity with ciliates.Results. Optimal conditions for growing R. mucilaginosa 111 on pea whey were determined (temperature 16.9°C, pH 7.8, amount of inoculum 1.85%). More biomass was synthesized on pea whey than on chickpea and potato whey – 81 g/dm3. The mass fraction of protein in the biomass is 58.90±3.03% on dry matter and the rate of essential amino acids is 119– 243%. Lipids included 20% saturated and 78% unsaturated fatty acids, linoleic acid – 45.26±0.70%, oleic – 24.04±0.76%, palmitoleic – 6.46±0.31%, palmitic – 13.70±0.81%. The yeast produced phytoin derivatives, torulene, β‐carotene, torularodin and phytoin. FMVC from pea whey stimulated the growth of ciliates Tetrahymena pyriformis by 29.1%, from chickpea whey (by 18.6% more intensively than distilled water), while potato whey reduced its growth rate.Conclusion. The dry biomass of the ecologically safe new yeast strain R. mucilaginosa 111 contained complete proteins, lipids, minerals, and carotenoids necessary for feeding animals. Thus liquid pea whey can be used for its biokonversions, while avoiding environmental pollution.

At the end of the last century and, especially, in the first two decades of the 21st century, a significant technological breakthrough took place in clinical laboratory diagnostics in Russia. The transition from manual techniques to high-tech and high-performance automated systems has changed the potential of laboratory medicine. The laboratory has become a high-tech, rapidly developing branch of medical organizations. Following the changes in technology, the range of diagnostic tests began to alter, while the list of laboratory tests available grew. These dynamics are growing every year. Simple routine techniques, practiced for all patients, are complemented by more specific tests. The place of conventional routine tests has been determined by many years of practical experience, while modern analyzers allow the use of tests with a high evidence value of recommendations, which, in the context of evidence-based medicine, enable the clinician to conduct a personalized diagnostic search. At the same time, in order to use all the possibilities of laboratory medicine, the discipline Clinical Laboratory Diagnostics should be included in educational programs at different stages of a doctor's training.
