Microbial Growth Lecture Materials

These are the Microbial Growth Lecture materials of the Virtual Microbiology Classroom. The resources below are used to supplement an actual college microbiology course. Anyone taking, teaching or interested in biology may find these materials helpful and is welcome to use them.

The Microbial Growth Lecture materials include:

a list of learning objectives

a PowerPoint lecture

"class note" articles

practice test questions

review questions

links to additional educational resources

MICROBIAL GROWTH LECTURE LEARNING OBJECTIVES

These lecture learning objectives are a study guide based on the VMC Microbial Growth Lecture PowerPoint:

Explain what “microbial growth” means.

Know the 4 phases of the microbial growth curve.

Understand how microorganisms are grouped based on their relationship with oxygen, temperature, pH & osmotic pressure.

How does bacterial generation time relate to characteristics of disease? (Another “think” question.)

Understand what it means for binary fission to result in exponential growth.

Understand the different factors that affect bacterial growth and how they influence the speed of population growth. Know any terminology associated with these factors.

Know the microbes that we met in this lecture and their relevance to the topics discussed.

- Mycobacterium tuberculosis and Generation time

- Mycobacterium leprae and Generation time

- Chlamydomonas nivalis and Temperature

- Listeria monocytogenes and Temperature

- Helicobacter pylori: pH & Oxygen

- Campylobacter jejuni and Oxygen

- Vibrio cholorae and pH

- Staphylococcus epidermidis and Osmotic Pressure

MICROBIAL GROWTH LECTURE POWERPOINT

All of the lecture PowerPoints used in the Virtual Microbiology Classroom have fill-in-the-blanks on many of the slides to encourage students to pay attention and follow along during the presentation. Instructors, contact us for the information that goes in the blanks.

HELPFUL TIPS: Some of the PowerPoint presentations are large files and may take a few moments to download, depending on the speed of your internet connection. If you are printing a hard copy of the PowerPoint, you can save paper by selecting Handouts (rather than Slides) in the "Print What:" drop down menu of the PPT print screen. Then you can choose the number of slides you want to have on each printed page. If the printed PPT presentation is to be used as student notes, it is best to choose handouts with 2 or 3 slides per page.

MICROBIAL GROWTH CLASS NOTES

Here are brief summaries of some of the various subtopics and concepts introduced in this lecture, kind of like really good class notes.

What Is the pH Scale? Measurement of Acidity & Alkalinity

Differential & Selective Bacterial Growth Media: MacConkey's, Mannitol Salt & Blood Agar

Binary Fission: Cell Division & Reproduction of Prokaryotes

MICROBIAL GROWTH PRACTICE TEST QUESTIONS Part I & Part II

Practice test questions designed to help you better understand the material from this lecture. They are based on information in the Microbial Growth PowerPoint Lecture.

MICROBIAL GROWTH REVIEW QUESTIONS

Questions designed to help you review the material in the Microbial Growth Lecture.
