Exercise 12: Aerotolerance Flashcards
1
Q
Aerotolerance
A
the ability or inability of microbes to grow in the presence of oxygen
2
Q
Thioglycollate Agar Deep
A
one method of determining aerotolerance
3
Q
Resazurin
A
- redox indicator added to medium
- a clear to red color change will indicate the absence or presence of dissolved oxygen in medium
4
Q
Obligate aerobes
A
require oxygen and will only grow in presence of oxygen (Micrococcus luteus)
5
Q
Facultative anaerobes
A
prefer the presence of oxygen but will grow quite well in absence of oxygen (E. coli)
6
Q
Obligate anaerobes
A
will not grow in presence of oxygen because oxygen is toxic to them (Clostridium sporogenes)
7
Q
Aerotolerant Anaerobes
A
prefer anaerobic conditions but oxygen is not toxic to them
8
Q
Microaerophiles
A
prefer a slightly lower atmospheric oxygen tension
