Nitrogen Fixation: Significance to Plants and Humans

1. Nitrogen Fixation: Significance to Plants and Humans

Almost 80% of our atmosphere is nitrogen, but we can't use it. We will look at how this unusable nitrogen is converted into a form we can use and why nitrogen is important to plants and humans.

The Nitrogen Cycle, Acid Rain and Fossil Fuels

2. The Nitrogen Cycle, Acid Rain and Fossil Fuels

Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.

Types of Bacteria Found in Anaerobic Environments

3. Types of Bacteria Found in Anaerobic Environments

This lesson will focus in on the world of anaerobes. We'll discuss the different types of anaerobes that abound on this planet, including obligate, facultative and aerotolerant anaerobes.

Bacteria that Live in Deepwater Vent Ecosystems

4. Bacteria that Live in Deepwater Vent Ecosystems

In this lesson, we will talk about hydrothermal vents, what they are, and what they release. We'll also look into why the substances they release are important for bacteria and higher life forms such as crabs and tubeworms.

Thermus Aquaticus and Other Thermophiles: Definition & Examples

5. Thermus Aquaticus and Other Thermophiles: Definition & Examples

This lesson will go into some very interesting creatures known as thermophiles. We will discuss exotic sounding names such as Strain 121 and Thermus aquaticus and how they revolutionized our thought process and technology.

Microbial Contamination in Drinking Water: Sources & Control

6. Microbial Contamination in Drinking Water: Sources & Control

This lesson will discuss what microbes may contaminate drinking water, what problems they may cause you, how we can test for them, and how we can control them. Find out as we look into coliform bacteria, giardia, and noroviruses.
