Ch 19: Food and Industrial Microbiology

About This Chapter

Watch online video lessons to learn about lactic acid fermentation, the Ames test and more. Each lesson is accompanied by a short multiple-choice quiz to help check your understanding of these food and industrial microbiology topics.

Food and Industrial Microbiology - Chapter Summary and Learning Objectives

Microbiology may seem out of place in the food-making process, but you may be surprised to learn that there are actually many ways it helps to create some of the most flavorful foods, such as cheese, sourdough bread and alcohol. In this chapter, you will see how bacteria, mold and plasmids are used in food-making. You will also study how fermentation of things like lactic acid and yeast are used to create food and drink items. Lessons will cover an array of topics to help you see the importance of microbiology in food-making. Some of the things you will learn include:

  • Fermentation in food-making
  • Mold's use in cheesemaking
  • Bacteria used to make proteins
  • Ames Test of Carcinogenesis

VideoObjective
Lactic Acid Fermentation: Using Fermentation to Make Food See how bacteria are used to make foods, like sauerkraut, yogurt, and sourdough bread.
Yeast Fermentation: Using Fermentation to Make Alcohol Study how yeast is used to make alcohol.
Bacteria and Mold: The Microbiology of Cheesemaking Learn how bacteria and mold are used during the cheesemaking process with different strains of mold, creating different cheese flavors and colors.
Microbial Factories: Using Bacteria to Make Specific Proteins Explore the steps in the process of using bacteria and plasmids to produce specific proteins in high concentrations.
The Ames Test: Using Bacteria to Test for Carcinogens Examine how bacteria can be used to test for carcinogens as well as the basis for this test.

7 Lessons in Chapter 19: Food and Industrial Microbiology
Lactic Acid Fermentation: Using Fermentation to Make Food

1. Lactic Acid Fermentation: Using Fermentation to Make Food

You eat food every day that is teeming with bacteria. It might surprise you to learn that many of them were intentionally put there. In this lesson, we will examine bacterial fermentation, required during the production of certain foods.

Yeast Fermentation: Using Fermentation to Make Alcohol

2. Yeast Fermentation: Using Fermentation to Make Alcohol

Without microbiology, you wouldn't be able to enjoy a refreshing adult beverage after work. In this lesson, we will examine the role of yeast in alcohol production.

Bacteria and Mold: The Microbiology of Cheesemaking

3. Bacteria and Mold: The Microbiology of Cheesemaking

Every piece of cheese you eat was produced by microbiology. In this lesson, we will examine the essential roles bacteria and mold play and why cheese wouldn't exist without these microbes.

Microbial Factories: Using Bacteria to Make Specific Compounds

4. Microbial Factories: Using Bacteria to Make Specific Compounds

Microbial factories make use of microorganisms to produce commercial products. In this lesson, we will examine the advantages to using microbes and look at a few commonly produced compounds.

The Ames Test: Using Bacteria to Test for Carcinogens

5. The Ames Test: Using Bacteria to Test for Carcinogens

We often think of bacteria as the bad guys. But in the Ames test, special mutant bacteria can help us avoid getting cancer! Take a look at how they do that in this lesson and test your knowledge with a quiz.

Bioremediation: Microbes Cleaning Up the Environment

6. Bioremediation: Microbes Cleaning Up the Environment

Bioremediation uses living organisms to clean up pollution. In this lesson, we will examine the role of microbes in bioremediation and why it is not a perfect solution for degrading environmental pollutants.

Microbes and the Clothing Industry

7. Microbes and the Clothing Industry

Most people wash their clothing to the clean dirt and bacteria on them. It might surprise you to learn just how many bacteria were intentionally put into them during production. In this lesson, we explore the use of microbes in the clothing industry.
