Saccharomyces cerevisiaea species of yeast. It has been instrumental in winemaking,baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
One of the most notable and well-known species of yeast in health and wellness is known as Saccharomyces cerevisiae, which is also known by its more common names, brewer's yeast or baker's yeast. Typically, brewer's yeast is used as a protein supplement, energy booster, immune enhancer, or other vehicle where other compounds can be inserted to create a commercialized health product.
The commercial product known as “nutritional yeast” contains the inactivated S. cerevisiae. This product is high in protein, fiber, and B vitamins, especially folic acid.
S.cerevisiae is a veterinary probiotic widely used in animal nutrition.
Although several S. cerevisiae strains have proven probiotic potential in humans.
Brewing& Bakers :
Saccharomyces cerevisiaeis used in brewing beer,
Baker's yeast is of the species Saccharomyces cerevisiae, and is the same species as the kind commonly used in alcoholic fermentation, which is called brewer's yeast.
Baker's yeast is the common name for the strains of yeast commonly used in baking bread and bakery products,serving as a leavening agent which causes the bread to rise by converting the fermentable sugars present in the dough into carbon dioxide and ethanol.
Uses in aquaria:
Owing to the high cost of commercial CO2 cylinder systems, CO2 injection by yeast is one of the most popular DIY approaches followed by aquaculturists for providing CO2 to underwater aquatic plants.
The yeast culture is, in general, maintained in plastic bottles, and typical systems provide one bubble every 3–7 seconds. Various approaches have been devised to allow proper absorption of the gas into the water.
Direct use in Human & animal Health:-
Besides being important in the fermentation of foods and beverages, yeasts have shown numerous beneficial effects on human health.
Among these, probiotic effects are the most well known health effects including prevention and treatment of intestinal diseases and immunomodulatory effects. Other beneficial functions of yeasts are improvement of bioavailability of minerals through the hydrolysis of phytate, folate biofortification and detoxification of mycotoxins due to surface binding to the yeast cell wall.
Useful for prevention or treatment Saccharomyces Cerevisiae var. boulardii in prevention (but not treatment) of traveler’s diarrheaent of several gastrointestinal diseases.
Topical treatment with a water-insoluble glucan from S. cerevisiae enhanced venous ulcer healingin humans. In a patient who had an ulcer that would not heal for over 15 years, this treatment caused a 67.8% decrease in the area of the ulcer.
S. cerevisiae and S. boulardii are clinically proven yeasts being used as a human probiotic and has shown to positively influence host’s health by antimicrobial effect, nutritional effect, inactivation of bacterial toxins, quorum sensing, trophic effects, immuno-modulatory effects, anti-inflammatory effects, cell restitution and maintenance of epithelial barrier integri.
One of the most desirable properties of probiotic yeasts is the anti-bacterial activity of yeasts against human pathogens.
The isolate pose desirable properties to be a potential probiotic. It can assimilate cholesterol (33%), can produce killer toxin, vitamin B12, glutathione, siderophore and strong biofilm.
