Lab - Quantification of Cultured Microorganisms
Experiment 1- Direct Counts Following Serial Dilution"
"Post-Lab Questions"
"1. What was the population density of the original sample? What would have happened if you had inoculated an agar plate with 1mL of the original sample?"
"2. Did all the bacterial colonies on the countable plate(s) have a similar appearance? If not, how would you explain this?"
"3. You have performed a serial dilution of an unknown sample and counted 73 CFU on a countable plate that was marked as a 10-4 dilution and you used 0.1mL to inoculate the plate. What is the population density of the original sample?"
"4. List at least one advantage and one disadvantage to the direct plate counting method following serial dilution for determining bacterial concentration."
"5. Compare and contrast direct plate counts for bacterial and viral populations."
"6. What are some sources of error in the serial dilution/direct plate counting method?"
