Saccharomyces is considered a yeast, although this term is historical and ill-defined. Saccharomyces is a genus of fungus including many species. The distinct species of Saccharomyces are revised frequently as more research is done. All species are unicellular and capable of fermentation. Saccharomyces cerevisiae is the most well known species of yeast. It is used in the fermentation of beer, wine, and sake, and as a leavening agent in bread. It is commonly referred to as "ale yeast", "wine yeast", or "bread yeast". S. pastorianus, known as lager yeast, is a hybrid closely related to S. cerevisiae but is not a true species. S. cerevisiae is commonly studied as a model organism and was the first eukaryote to have its genome entirely sequenced.

Species

Saccharomyces cerevisiae is the type species of the genus Saccharomyces, although Saccharomyces paradoxus, S. cerevisiae's closest relative, is likely older and more globally ubiquitous than S. cerevisiae. [1]
