Macromorphology (smell):

Micromorphology:

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.

Taxonomy/phylogeny:

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.
