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.
Saccharomycetes belongs to the Ascomycota division of the kingdom Fungi.It is the only class in the subdivision Saccharomycotina, the budding yeasts.Saccharomycetes contains a single order, Saccharomycetales.
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 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.
Saccharomyces cerevisiae as seen under a Differential Interference Contrast (DIC) microscope The yeast genus Saccharomyces (sugar mold) is favored for winemaking (for both grapes as well as other fruit wines in addition to being used in brewing and breadmaking) because of the generally reliable and positive attributes it can bring to the wine.
It appears similar to common brewers' yeast, Saccharomyces cerevisiae, under a microscope. [6] It undergoes division by bud-fission. For sexual reproduction, its ascospores are small and spherical, with asci commonly composed of 1 to 4 ascospores. [7]
