Yeast cells (Saccharomyces cerevisiae)

Yeast cells. Illustration of cells of brewer’s, or baker’s, yeast (Saccharomyces cerevisiae). It is used in the production of beer, wine and bread.

Saccharomyces cerevisiae is also known as budding yeast and is key to brewing, baking and winemaking. It is a popular model organism in genetics research, particularly in the field of cell biology. It is one of the most commonly used model organisms to study eukaryotic cells. Many proteins involved in the cell cycle and signalling were first discovered in yeast. Saccharomyces cerevisiae is typical found on the surface of ripe fruits such as grapes. This fungus consists of single vegetative cells. S. cerevisiae ferments sugar, producing alcohol and carbon dioxide in the process
