MICRB 202 Exam 1 Notes
Experiment 1: The Compound Microscope Compound microscope multiple lenses in sequence Bright-field, phase-contrast, fluorescence types of light microscopes Electron microscopes use electron beams instead of light, include
The Effect of Preservatives on Spore Growth
Hypothesis: Preservatives decrease the growth of spore development.
Prediction: Bread that contains preservatives will have less spore development than bread
Treatments and Controls: The c
Hypothesis: One species of bacteria is infecting the green pepper.
Prediction: The isolated culture will grow on the TSA and not the PDA.
Treatment and Controls:
First, a culture will be isolated from a healthy pepper to be used as a cont
Determining if Cell Mutations are Induced or Occur Spontaneously
Hypothesis: Mutations in cells occur spontaneously.
Prediction: The variance in the number of colonies that grew on T4 phage for different cultures
of E coli will be much larger than the var
Host Specificity of Isolated P. Acnes Culture
Hypothesis: Our P. Acnes culture will not be resistant to the majority of other classmates phage.
Prediction: Plaques will take up the majority of the grid in spot titer, because the P. Acnes was
The Motility of E Coli with respect to Certain Chemicals
Hypothesis: E coli is attracted to amino acids, and repelled by carbon groups.
Prediction: E coli will move towards amino acids on the disk and away from the carbon groups.
Treatment and Controls: F
Micrb 202 Section 002
P. Acne and Bacteriophage
Group Member: Jiayan Zhou, Lu Yang, Mingyue Zhang
Hypothesis: Our P. Acne is least resistant to phage isolated.
The value of phage titer is biggest for our P. Acne i
Experiment 17- Milk Microbiology
-Milk is a good medium, it has fat carbs vitamins minerals amino acids sugars, so it is
prone to bacteria
-Inevitable that some bacteria will get into the milk at the facility
-Most are harmless, such as the so
-antibiotics are selectively toxic in that they target structures enzymes or pathways
that are unique to bacteria
-spectrum of an antibiotic: range if bacterial species that are inhibited or killed by
-sensitive: bacteria is inhibit
