Saccharomyces Cerevisiae

Saccharomyces cerevisiae, also called brewer's yeast or baker's yeast, is a single-celled fungal microorganism in the family Saccharomycetaceae, with round to ovoid cells 5 to 10 micrometers in diameter that reproduce by budding. It has been instrumental in winemaking, baking, and brewing since ancient times and is among the most intensively studied eukaryotic model organisms in molecular and cell biology, serving as the organism in which many human proteins, including cell cycle and signaling proteins, were first identified through their yeast equivalents.
