There are several types of yeast commonly used in food production, including:
1. Baker's yeast: This is the most common type of yeast used in baking bread and other baked goods. It is typically sold in dry, granulated form and is activated by mixing it with warm water and sugar.
2. Brewer's yeast: This type of yeast is used in the production of beer and other fermented beverages. It is a byproduct of the beer-making process and is often sold as a nutritional supplement due to its high protein and vitamin content.
3. Nutritional yeast: This type of yeast is often used as a flavoring agent in vegan and vegetarian dishes. It has a cheesy, nutty flavor and is often sprinkled on top of dishes like pasta, popcorn, or salads.
4. Wild yeast: This type of yeast occurs naturally in the environment and is often used in sourdough bread making. It is typically captured from the air or from the skins of fruits and vegetables and can give bread a unique flavor and texture.
5. Active dry yeast: This type of yeast is similar to baker's yeast but is sold in a different form. It is typically granulated and needs to be dissolved in warm water before use.
6. Instant yeast: This type of yeast is similar to active dry yeast but does not need to be dissolved in water before use. It can be added directly to dry ingredients in recipes.
7. Rapid-rise yeast: This type of yeast is a quick-acting version of active dry yeast and is often used in recipes that require a shorter rise time.
These are just a few of the most common types of yeast used in food production, but there are many other varieties available for specific applications.

- Baker's yeast (Saccharomyces cerevisiae) is the most common type of yeast used in food production. It is used to make bread, beer, wine, and other fermented foods. Baker's yeast is a facultative anaerobe, meaning that it can grow in both the presence and absence of oxygen. When oxygen is present, baker's yeast will respire and produce carbon dioxide and water. When oxygen is absent, baker's yeast will ferment sugars and produce ethanol and carbon dioxide.
- Brewer's yeast (Saccharomyces cerevisiae var. diastaticus) is a strain of baker's yeast that is specifically used to make beer. Brewer's yeast is more tolerant of alcohol than baker's yeast, which allows it to ferment sugars at higher concentrations. Brewer's yeast also produces a number of enzymes that are important for the brewing process, such as alpha-amylase and beta-glucanase.
- Wine yeast (Saccharomyces cerevisiae var. cerevisiae) is a strain of baker's yeast that is specifically used to make wine. Wine yeast is more tolerant of acidity than baker's yeast, which allows it to ferment sugars at lower pH levels. Wine yeast also produces a number of enzymes that are important for the winemaking process, such as malolactic enzyme and pectinase.
- Dairy yeast (Kluyveromyces lactis) is a type of yeast that is used to make cheese and other dairy products. Dairy yeast is a lactic acid bacterium, meaning that it produces lactic acid as a byproduct of fermentation. Lactic acid is responsible for the sour flavor of cheese and other dairy products.
- Torula yeast (Candida utilis) is a type of yeast that is used to produce food-grade yeast extract. Food-grade yeast extract is a flavorful and nutritious ingredient that is used in a variety of foods, such as soups, sauces, and salad dressings.
