Chapter 6, Problem 2CT

Pasteurization is a technique that uses temperatures of about 72°C to neutralize potential pathogens in foods. What effect does this temperature have on the enzymes and cellular metabolism of pathogens? Why does the heat of pasteurization kill some microorganisms yet fail to affect thermophiles?

List 5 physical methods of controlling microbial growth, and give an example of each. Why is moist heat much more effective than dry air?
The thermal death point refers to: O 1) The time it takes to kill an organism in an autoclave 2) The temperature it requires to kill an organism within 10 minutes 3) The time it takes to kill an organism at a chosen temperature O 4) The temperature required to kill prions O 5) The time required to disinfect a surface
1(a)What is a psychrotroph? (b)From what natural sources would you isolate a thermophile? A psychrophile? (C)How does temperature affect the growth of a microorganism? (D)State the temperature class for Escherichia coli, Bacillus sp, Aeromonas sp, Micrococcus luteus, and suggest their optimum growth temperature. 2 (a)Why is dilution important when determining microbe number? (B)How does a decrease in dye colour intensity affect the microbe ? (C)State the possible sources of error if plate counts and colour intensity of dilutions are incorrect or Precautions taken to prevent this from happening. ( this is not a graded assignment)
