Name _________________________________ BioMI 418 Microbial Ecology Exercise 3 (10 points) due Friday Feb 15, 2008 “I will survive: DNA protection in bacterial spores”: 1) There have been many biochemical and genetic studies focused on B. subtilis to determine which features of endospores are responsible for their incredible resistance traits. Describe the following two traits and their role in DNA protection. a) What does “Ca-DPA” stand for? Compared to spores with normal DPA levels, spores without DPA are more sensitive to: While spores without DPA are more resistant to:

Unformatted text preview: b) What does SASP stand for? What are the roles of SASP in spore resistance? 2) Review the process of endospore formation (sporulation) as described by Setlow. At the start of spore formation, just after engulfment of the forespore by the mother cell, if you killed the mother cell would the endospore be able to fully mature? Provide reasons to support your answer. 3) What is pasteurization? What kinds of foods are pasteurized? Does pasteurization kill endospores?...
