S. cerevisiae

Saccharomyces cerevisiae, commonly known as baker's or brewer's yeast, is a single-celled fungus used in baking, brewing, and winemaking. It ferments sugars, producing carbon dioxide and alcohol, which helps bread rise and gives beer and wine their distinctive flavors. This organism is crucial in food production and is also studied in scientific research due to its simple genetic structure and rapid reproduction. S. cerevisiae is often referred to as a model organism in genetics and cell biology, helping scientists understand fundamental processes that apply to other organisms, including humans.
