Обычно используется для профилактики или лечения острой диареи и других желудочно-кишечных расстройств, включая антибиотик-ассоциированную диарею, вызванную инфекциями Clostridium difficile. Отсутствие зарегистрированной и доступной к реализации технологии культивирования пробиотических дрожжей, а также выпуск препарата в сухой активной форме, ставит несколько фундаментальных задач для исследования. Помимо подбора питательной среды и разработки технологии получения биомассы, необходимо создать условия для повышения ксерорезистентности культуры. В процессе жизненного цикла получения пробиотического лиофилизата дрожжей Saccharomyces cerevisiae boulardii на культуру воздействует множество стрессов. Возникновение стрессов, способствует снижению активности штамма, а также при воздействии окислительного и термических стрессов, запрограммированной гибели клеток, что представляет риск для жизнеспособности пробиотических микробов. В результате снижается метаболическая активность дрожжей и увеличивается количество нежизнеспособных клеток. Одним из способов сохранения физиологической активности клеток после дегидратации является направленный синтез трегалозы. Исследования, проведенные с пекарскими дрожжами Saccharomyces cerevisiae свидетельствуют от том, что трегалоза – синтезируется при отсутсвии эффекта Кребтри в стационарной стадии роста при температуре от 37 до 42 ℃. Сведений о биосинтезе трегалозы в дрожжах Saccharomyces cerevisiae boulardii отсутствуют. Исследование отражает зависимость углеродного состава и параметров культивирования, на процесс накопления трегалозы клеткой. Представлены сравнения потенциала образования трегалозы в культурах Saccharomyces cerevisiae boulardii от Saccharomyces cerevisiae. В результате проведения исследований установлено, что для получения ксерорезистентных дрожжей, содержащих более 15 % трегалозы, способствует культивирование Saccharomyces cerevisiae boulardii при температуре 39–40 ℃ с дефицитом питательных веществ в среде.</p></abstract><trans-abstract xml:lang="en"><p>Saccharomyces cerevisiae var. boulardii (S. boulardii) is a probiotic yeast strain that is the only yeast probiotic approved by the FDA (U.S. Food and Drug Administration) for clinical use. It is commonly used to prevent or treat acute diarrhea and other gastrointestinal disorders, including antibiotic-associated diarrhea caused by Clostridium difficile infections. The lack of a registered and available technology for the cultivation of probiotic yeast, as well as the release of the drug in a dry active form, poses several fundamental tasks for the study. In addition to the selection of a nutrient medium and the development of a technology for obtaining biomass, it is necessary to create conditions for increasing the xeroresistance of the crop. During the life cycle of Saccharomyces cerevisiae boulardii yeast probiotic lyophilisate, the culture is exposed to many stresses. The occurrence of stress contributes to a decrease in the activity of the strain, as well as when exposed to oxidative and thermal stresses, programmed cell death, which poses a risk to the viability of probiotic microbes. As a result, the metabolic activity of yeast decreases, and the number of non-viable cells increases. One of the ways to preserve the physiological activity of cells after dehydration is the directed synthesis of trehalose. Studies conducted with baker's yeast Saccharomyces cerevisiae indicate that trehalose is synthesized in the absence of the Crabtree effect in the stationary stage of growth at a temperature of 37 to 42 ℃. There is no information about the biosynthesis of trehalose in the yeast Saccharomyces cerevisiae boulardii. The study reflects the dependence of the carbon composition and cultivation parameters on the process of trehalose accumulation by the cell. Comparisons of the potential for trehalose formation in Saccharomyces cerevisiae boulardii cultures from Saccharomyces cerevisiae are presented. As a result of the research, it has been established that to obtain xeroresistant yeasts containing more than 15 % trehalose, the cultivation of Saccharomyces cerevisiae boulardii at a temperature of 39–40 ℃ with a deficiency of nutrients in the medium is facilitated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дрожжи</kwd><kwd>пробиотики</kwd><kwd>трегалоза</kwd><kwd>питание</kwd><kwd>выживаемость микроорганизмов</kwd><kwd>культивирование</kwd><kwd>штамм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>yeast</kwd><kwd>probiotics</kwd><kwd>trehalose</kwd><kwd>nutrition</kwd><kwd>survival of microorganisms</kwd><kwd>cultivation</kwd><kwd>strain</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">U.S. Food and Drug Administration: официальный сайт.
