Use this graph showing the standard death curves of three microbial species to answer the following two questions.
The three microbial species shown in the graph where all treated at 70° C. If you had to sterilize a food product that contained 107 bacteria, how long would it take for each bacterial species?
Calculate the D70 values for these three bacterial populations.
For the next three questions, assume D90 = 22 minutes.
At what temperature will you treat a food product?
How long does it take you to kill 90% of bacteria?
How long will it take you to sterilize a food product if it had 109 bacteria on it?
Serial Dilutions
6a. A sample is given to you that contains 6 million cells per ml. You must make a series of serial dilutions in order to get a countable number on a plate to prove that there are indeed 6 million cells per ml. The plate that you eventually put a sample of bacteria on must have between 10 and 100 colonies for ease of counting. What…
