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

  • 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  


LECTURE POWERPOINT
Versions of Microbial Growth PPT:​

Printing: The best way for students to print out the PowerPoint Show is to download the PDF version. Select Print, and, when the Print screen comes up, go to the Print Handling options. Under Page Scaling, select "Multiple pages per sheet". Under Pages Per Sheet, select "2". This uses up less paper, placing two slides on each page.


The Microbial Growth Lecture materials include:
  • list of learning objectives
  • PowerPoint lecture   
  • practice test & review questions
  • links to additional educational resources
