There are different types of yeasts used in various food and beverage preparations-

1. Bakers yeast-

It is S. cerevisiae culture, it acts as a leavening agent. The carbon dioxide produced by yeast helps the dough to rise. Also, the production of ethanol and small amounts of organic compounds is responsible for mellowing of dough as well as providing aroma.

2. Brewers yeast-

It is also S. cerevisiae. It is used for brewing wine, beer. Brewer’s yeast is also used as a nutritional supplement as it is rich in chromium and vitamin B.
