1. Introduction to Microbiology

2. How do microorganisms affect our lives?

3. What are some benefits of microorganisms?
produce food
recycle nutrients
use as research tools
cause disease
What is a harmful affects of microorganisms?

4. What are some foods that are produced by microorganisms?
Pickles
Sauerkraut
Bread
Beverages

Sour cream

5. Difference Between Fermentation and Curdling
Fermentation - sugars break down into alcohol - maybe in the food or not (bread & cakes; beer & wine) normal pH conditions
Curdling - proteins clumped into tight balls or bands (clumps = curds) low pH created by bacterial waste

6. Recycling of Microorganisms
Carbon, nitrogen, phosphorus

7. Industrial Applications of Microorganisms
Protease (used in detergents), pectinase (baby food), starch formers, clay, linen, recycling, bioremediation

8. Genetic Engineering
DNA chemistry is the same, small & easy to grow in lab, easy to manipulate (simple structure), no moral problems

9. Infectious Diseases Pathos – ill, bad Genic – making
Virus, bacteria, protozoa, and fungi
