Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
The yeast has a negative effect on the bacteria that normally produce antibiotics to kill the parasite, so may affect the ants' health by allowing the parasite to spread. [41] Certain strains of some species of yeasts produce proteins called yeast killer toxins that allow them to eliminate competing strains. (See main article on killer yeast ...
Y187 is a strain of yeast (Saccharomyces cerevisiae) used in biological research for two-hybrid screening.The strain has been sold commercially by Clontech [1] since at least 2000 and is used as a partner with strain AH109 in mating assays.
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
Saccharomyces boulardii is a tropical yeast first isolated from lychee and mangosteen peels in 1923 by French scientist Henri Boulard.Although early reports claimed distinct taxonomic, metabolic, and genetic properties, [1] S. boulardii is a grouping of S. cerevisiae strains, all sharing a >99% genomic relatedness.
The National Collection of Yeast Cultures (NCYC) is a British yeast culture collection based at the Norwich Research Park in Norwich, Norfolk, United Kingdom, that currently maintains a collection of over 4400 strains and operates under the Budapest Treaty. [1]

Saccharomyces is a genus of fungi that includes many species of yeasts. Saccharomyces is from Greek σάκχαρον (sugar) and μύκης (fungus) and means sugar fungus.Many members of this genus are considered very important in food production where they are known as brewer's yeast, baker's yeast and sourdough starter among others.
