Ch 3: Microbiology Laboratory Procedures

About This Chapter

Improve your understanding of microbiology lab procedures with this convenient science chapter. Inside, you'll find fun lessons and quizzes that can help you prepare for an upcoming exam, get ahead in class and complete homework or class assignments.

Microbiology Laboratory Procedures - Chapter Summary

This chapter helps you review a variety of lab procedures in microbiology. Follow along with our expert instructors to study topics like microscopy, Gram stains, bacterial growth mechanisms, serial dilution and bacterial enumeration. Each lesson comes with a short self-assessment quiz, and the chapter concludes with a comprehensive multiple-choice exam. Our instructors are happy to help you out if you have any questions. You can study the chapter at any time using your desktop, laptop or mobile device. By the end of the chapter, you should be able to:

  • Explain the applications and types of microscopy
  • Compare simple and differential stains
  • Recognize a Gram stain background
  • Assess Gram stain procedure and theory
  • Identify types of bacterial growth mechanisms
  • Evaluate lab experiments for bacteria growth
  • Interpret the phases and stages of bacterial growth and generation time
  • Define the bacterial enumeration method

Microscopy Types & Applications

1. Microscopy Types & Applications

What is microscopy and how do we use it? Learn about the different types of microscopes and the ways we use them for practical purposes. You can then take a quiz and test what you've learned.

Simple and Differential Stains: Definition and Examples

2. Simple and Differential Stains: Definition and Examples

Observing tiny bacteria under the microscope is not as easy as it sounds. In this lesson, we will examine several staining techniques used to color bacteria, enhancing their visibility.

The Gram Stain: Background and Example Organisms

3. The Gram Stain: Background and Example Organisms

Every microbiology student should be familiar with the Gram stain. In this first of two lessons on this technique, we will look at some of the background information before describing and viewing some relevant example organisms.

The Gram Stain: Theory and Procedure

4. The Gram Stain: Theory and Procedure

In this lesson, we will focus on the individual steps of the Gram stain procedure. In this second of two lessons on the Gram stain, we will examine the theory and procedure behind how each step contributes to the process as a whole.

Growing Bacteria in a Lab: Experiments & Conditions

5. Growing Bacteria in a Lab: Experiments & Conditions

Despite the fact that bacteria are growing all around you, they can be surprisingly difficult to grow in a lab. This lesson will explore some of the basics involved in culturing bacteria for experimentation.

What Is Bacterial Growth & Generation Time? - Curves, Phases & Stages

6. What Is Bacterial Growth & Generation Time? - Curves, Phases & Stages

Bacteria are able to reproduce at an incredibly rapid pace. In this lesson, we will examine the different phases of bacterial growth and how to calculate population numbers based on generation times and culture size.

Bacterial Enumeration: Definition, Methods & Example

7. Bacterial Enumeration: Definition, Methods & Example

In this lesson, we'll learn about bacterial enumeration. We will discuss what this process is and different enumeration methods such as standard plate count, direct microscopic counts, cell mass determination, measurement of cellular activity, and much more.

Serial Dilution in Microbiology: Calculation, Method & Technique

8. Serial Dilution in Microbiology: Calculation, Method & Technique

Working with billions of tiny cells can pose a problem when you need to count the total number of cells in a sample. Fortunately, through precise serial dilution of a sample, it is possible to get down to a number that is much easier to work with.

Differential & Selective Media in Microbiology

9. Differential & Selective Media in Microbiology

Every microbiologist eventually has to grow cultures of bacteria for their experiments. In this lesson, we will investigate selective and differential media, two techniques to make culturing bacterial species a little more efficient.
