I’m trying to learn for my Biology class and I’m stuck. Can you help?
Bio 152 Exam 2 Lab Stuff Study Guide
- 2-8 Effect of Temp (p 105)
- 2-9 Effect of pH (p 111)
- Pipetting Exercise
- 6-2Standard Plate Count (p 411)
- 2-6 Fluid Thioglycollate Broth (p 95)
- 2-7 Anaerobic Jar (p 101)
- 2-11 Steam Sterilization (p 125)
How does temperature affect bacterial growth?
Given hypothetical growth data for bacteria incubated at different temperatures, be able to classify bacteria based on temp requirements ( psychrophile, mesophile, thermophile, hyperthermophile)?
Be able to answer question #6 on p. 110.
How does pH affect bacterial growth?
Given hypothetical growth data for bacteria incubated in different pH broths, be able to classify bacteria based on pH requirements ( acidophile, neutrophile, alkalinophile)?
Know how to properly use a serological pipette. For help check out these youtube videos:
Review slides 50-57 in lecture 5.
Here is a sample problem- Calculate the cell density (CFU/mL) of the source culture below:
What should sterile FTB look like? (see fig 2.36 p 96)What does the pink region indicate?
Be able to answer question 1 on p 99.
Know the aerotolerance classifications for the organisms used in this experiment: P fluorescens, C sporogenes, S epidermidis
Be able to answer questions 1-4(on p 103-104)
Was our growth data for P fluorescens, C sporogenes, S epidermidis consistent with our findings in exercise 2-6?
Why do typical biological indicators contain bacterial endospores?
After the ampules inside the vials have been crushed, what does a purple color indicate? What does a yellow color indicate?
