PROSPECTS OF USING CANDIDA PARAPSILOSIS IN THE PRODUCTION OF FEED PROTEIN
The use of feed yeasts compensates for protein deficiency in the animals’ diet and increases their productivity, while the need to study feed yeasts is due to their subsequent use as feed protein. The research was carried out in the Research Institute of Biotechnology, FSBI HE Gorsky State Agrarian University, Vladikavkaz, the aim of which was to produce yeasts biomass Candida parapsilosis on the cattle manure hydrolyzate. The research showed that the nutrient medium obtained by hydrolysis of complex organic substances of cattle manure is a promising raw material for the cultivation of microorganisms and is characterized by high biomass yield, high rate of biomass growth and high concentration of budding cells in the lag phase. The recultivation was taken and properties of the yeasts Candida parapsilosis, strain 17A (collection № CMIM Y-439) were studied. The authors studied the physico-chemical parameters of yeasts biomass and determined the economic efficiency of biomass production Candida parapsilosis, strain 17A on the hydrolyzate of cattle manure. The best mode of cattle manure hydrolysis was the pressure of 1.5 atm. for 1.5 hours. The content of sugars in the manure hydrolyzate was 15.3 g/dm3. As a result of cultivation, a biomass of feed yeasts was obtained in which the protein content was 49.7%. The profitability of production is 22.2%.
