description The invention relates to biotechnology, in particular to a process for preserving the Saccharomyces cerevisiae CNMN-Y-20 yeast strain, which can be used for long-term storage of microorganisms and their use as sources of biologically active substances.The process, according to the invention, consists in cultivating the Saccharomyces cerevisiae CNMN-Y-20 yeast strain on a nutrient medium for 72 hours at a temperature of 26...28°C, suspending the culture to a titer of 105...106 ml-1 in a medium consisting of skim milk and 5...10% vol. 65% water-ethanol solution, comprising 5 mg/ml of extract, obtained from spirulina biomass, rapid freezing of suspension at a temperature of -20°C, lyophilization and storage at a temperature of 4°C.The technical result of the invention consists in increasing the protein content in the Saccharomyces cerevisiae CNMN-Y-20 yeast biomass after one year of storage in a lyophilized state by 20.70...40.48%. Invenţia se referă la biotehnologie, şi anume la un procedeu de conservare a tulpinii de levuri Saccharomyces cerevisiae CNMN-Y-20, care poate fi utilizat pentru păstrarea microorganismelor pe un termen îndelungat şi utilizarea acestora ca surse de substanţe biologic active.Procedeul, conform invenţiei, constă în cultivarea tulpinii de levuri Saccharomyces cerevisiae CNMN-Y-20 pe un mediu nutritiv în decurs de 72 de ore la temperatura de 26...28°C, suspensionarea culturii până la titrul de 105...106 ml-1 într-un mediu constituit din lapte degresat şi 5...10% vol. soluţie hidroetanolică de 65%, care conţine 5 mg/ml de extract, obţinut din biomasa de spirulină, congelarea rapidă a suspensiei la temperatura de -20°C, liofilizarea şi păstrarea la temperatura de 4°C.Rezultatul tehnic al invenţiei constă în majorarea conţinutului de proteine în biomasa de levuri Saccharomyces cerevisiae CNMN-Y-20 după un an de păstrare în stare liofilizată cu 20,70...40,48%. Изобретение относится к биотехнологии, а именно к способу консервирования штамма дрожжей Saccharomyces cerevisiae CNMN-Y-20, который может быть использован для долговременного хранения микроорганизмов и их использования в качестве источников биологически активных веществ.Способ, согласно изобретению, заключается в культивировании штамма Saccharomyces cerevisiae CNMN-Y-20 на питательной среде в течение 72 часов при температуре 26...28°C, суспендировании культуры до титра 105...106 мл-1 в среде, состоящей из обезжиренного молока и 5...10%об. 65%-ного водно-этанольного раствора, содержа
