Species/Subspecies: Saccharomyces cerevisiae
Category: Of practical use
Etymology: Genus name: sugar fungus.
Species epithet: from beer.
Significance:  [Important]   
Macromorphology (smell):
Saccharomyces cerevisiae 
Saccharomyces cerevisiae
Metabolism: S. cerevisiae is facultatively anaerobic. Ethanol and carbon dioxide are generated by fermentation.
Reproduction: S. cerevisiae reproduces asexually through budding like other yeasts, but can also form ascospores and reproduce sexually.
Spec. Char.: Like other yeasts, S. cerevisiae has a relatively short generation time (1.25-2 hours).
Disease/effect: A variant of S. cerevisiae , known as S. boulardii and which is included in certain probiotics, has, however, been shown to account for about 40% of human saccharomycoses.

Comment:Used for the production of wine and beer and for baking. Also very useful as a model system for eukaryotic cells in cell biology. S. cerevisiae was the first eukaryotic organism for which the entire genome was sequenced in 1996.
