Give three examples of traditional foods made with the help of microbes.

  • Bread, cheese, and yogurt are traditional foods made with the help of microbes.

Microbes are involved in baking and dairy products:

  • Baking: Yeast (Saccharomyces cerevisiae) is used in bread making.
  • Dairy products: Bacteria like Lactobacillus and Streptococcus are involved in yogurt and cheese production.

Source of the sugars that are fermented in brewing:

  • The sugars fermented in brewing are usually derived from barley or other grains, where starch is converted into sugars during malting.

Bubbles of carbon dioxide gas help to make bread;

  • The bubbles of carbon dioxide gas produced by yeast fermentation cause the dough to rise, giving the bread its light and airy texture.
