Saccharomyces cerevisiae (often abbreviated as S. cerevisiae) is a remarkable species of yeast, commonly known as brewer’s yeast or baker’s yeast.

• S. cerevisiae is responsible for many common types of fermentation.

• In brewing, it converts sugars into alcohol, creating beer and other alcoholic beverages.

• In baking, it produces carbon dioxide, causing dough to rise and giving bread its characteristic texture.
