Yeast is used in bakeries and breweries-

• In bakeries : Yeast added to the dough ferments sugar and produces carbon dioxide which causes the dough to rise and gives the bread a light and spongy texture.
  
• In breweries : Yeast takes part in the production of alcoholic beverages like wine and beer by the process known as fermentation. Fruits like grapes, strawberries, plums etc. are used to produce alcoholic beverages.
