Screening of Yeast Crops as Potential Producers of Complete Protein on Oil Production Waste

Abstract

The article presents the result of the screening of yeast cultures on oilseed waste. When choosing promising producers among pure yeast cultures, it is worth paying attention to such parameters as: biomass accumulation, "crude" protein accumulation and conversion. The work used microorganisms from the National Bioresource Center of the All-Russian Collection of Industrial Microorganisms (VKPM) NRC "Kurchatov Institute" -GosNIIgenetics, Russian Collection of Agricultural Microorganisms (RCAM), Collections of the Department of "Biotechnology and technology of products of bioorganic synthesis" FSBEI VO MGUPP. Screenings were performed on solid and liquid culture media. As a result of screening potential protein producers, the following strains were selected for further work on the development of a technology for obtaining high-quality biomass: Kluyveromyces marxianus Candida blancii RCAM3343,. The first two strains can be used to obtain protein concentrates and isolates, which can be used to obtain a biologically active supplement to human food.
