| 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.
| Hosts/substrate | Disease/effect | Clinical picture or result |
|---|
| Humans with a weakened immune system. | Saccharomycosis | Some strains of S. cerevisiae can, in unfortunate and very unusual circumstances, cause invasive infection in humans. |

| 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. |
