introduction: the purpose of this study was formulation and preparation of a proper culture medium for saccharomyces cerevisiae var. boulardii with molasses and animal serum. methods: a fully-crossed factorial design contain 5%, 10% and 20% of molasses (m) with 0, 1% and 5% animal serum (s) was used in this study. the ph of all culture medias were adjusted to 5.6 with acetic acid. the seed was ...

Probiotics are commonly prescribed as an adjuvant in the treatment of antibiotic-associated diarrhea caused by Clostridium difficile. We report the case of an immunocompromised 73-year-old patient on chemotherapy who developed Saccharomyces cerevisiae var. boulardii fungemia in a central venous catheter during treatment of antibiotic-associated pseudomembranous colitis with the probiotic Saccha...

BACKGROUND Saccharomyces cerevisiae var. boulardii is the only yeast species with probiotic properties. It is considered to have therapeutic significance in gastrointestinal disorders. In the present study, a comparative physiological study between this yeast and Saccharomyces cerevisiae (BY4742) was performed by evaluating two prominent traits of probiotic species, responses to different stres...

The discovery and study of the budding yeast Saccharomyces cerevisiae var. boulardii (Sb) is strictly related to the concept of health promoting microorganisms from food. The first most well-known and popularized throughout Europe assumption of health promoting food containing living microorganisms was yogurt. Appointed in 1888 by Louis Pasteur, Ilya Ilyich Metchnikov working in Paris developed...

Food Sci., 33: 8–12. This article proposes an approach based on the evaluation of CO2 produced by Saccharomyces cerevisiae var. boulardii, Kluyveromyces lactis × Saccharomyces cerevisiae, Saccharomyces pastorianu...

In this paper, comparative molecular studies between authentic Saccharomyces cerevisiae strains, related species, and the strain described as Saccharomyces boulardii were performed. The response of a S. boulardii strain and a S. cerevisiae strain (W303) to different stress conditions was also evaluated. The results obtained in this study show that S. boulardii is genetically very close or nearl...

Probiotic microorganisms (Saccharomyces cerevisiae var. boulardii, S. cerevisiae UFMG 905, and Lactobacillus delbrueckii UFV H2b20) were evaluated as biological control agents to reduce aflatoxin and spore production by Aspergillus parasiticus IMI 242695 in peanut. Suspensions containing the probiotics alone or in combinations were tested by sprinkling on the grains followed by incubation for s...

Saccharomyces boulardii is a probiotic yeast related to Saccharomyces cerevisiae but with distinct genetic, taxonomic, and metabolic properties. S. cerevisiae has been used extensively in biotechnological applications. a variety of strains are available, and multiple genetic tools have been developed, allowing the expression of exogenous proteins of interest with applications in the fields of m...
