Yeast

Yeast is a single-celled microorganism that can exist either as a free-living organism or as a symbiotic species. Generally found in soil, plants, fruits, and vegetables, yeast can also be grown in labs and used to produce alcohol, carbon dioxide, and other chemical compounds. It is most commonly used in the process of bread-making and beer-brewing, due to its ability to convert sugars into alcohol and carbon dioxide. In addition to its culinary uses, yeast has many biomedical applications, such as producing pharmaceutical compounds and producing proteins for medical and industrial uses. Yeast is a vital organism for the production of food and for medical research, and its importance will continue to be recognized for years to come.
