13 Facts About Saccharomyces cerevisiae

Saccharomyces cerevisiae created yeast that would rise twice as fast, cutting down on baking time.

Saccharomyces cerevisiae is relevant to cell cycle studies because it divides asymmetrically by using a polarized cell to make two daughters with different fates and sizes.

The yeast species S pombe and S cerevisiae are both well studied; these two species diverged approximately, and are significant tools in the study of DNA damage and repair mechanisms.

Saccharomyces cerevisiae has developed as a model organism because it scores favorably on a number of these criteria.

Evidence from studies of S cerevisiae bear on the adaptive function of meiosis and recombination.

Mutations defective in genes essential for meiotic and mitotic recombination in S cerevisiae cause increased sensitivity to radiation or DNA damaging chemicals.

Saccharomyces cerevisiae was the first eukaryotic genome to be completely sequenced.

Saccharomyces cerevisiae is used in brewing beer, when it is sometimes called a top-fermenting or top-cropping yeast.

Saccharomyces cerevisiae is used in baking; the carbon dioxide generated by the fermentation is used as a leavening agent in bread and other baked goods.

Saccharomyces cerevisiae is the main source of nutritional yeast, which is sold commercially as a food product.

Saccharomyces cerevisiae is proven to be an opportunistic human pathogen, though of relatively low virulence.

Saccharomyces cerevisiae was found in the skin, oral cavity, oropharinx, duodenal mucosa, digestive tract, and vagina of healthy humans .

Some specialists consider S cerevisiae to be a part of the normal microbiota of the gastrointestinal tract, the respiratory tract, and the vagina of humans, while others believe that the species cannot be called a true commensal because it originates in food.
