QUESTIONS Consider aerotolerance categories and their growth

QUESTIONS Consider aerotolerance categories and their growth in FTB. b. Anaerobe? c. Microaerophile? d, Facultative anaerobe? e. Aero tolerant anaerober SECTION 2 Microbial Growth 99

Solution

B. Anaerobe-  anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if oxygen is present.

C.Microaerophile- An aerobic bacterium that requires oxygen, but less than is present in the air, and grows best under modifiedatmospheric conditions.

D. Facultative anaerobe - Facultative anaerobes, which can grow without oxygen but use oxygen if it is present

E.. Aerotolerant anaerobe - An aerotolerant anaerobe is an organism that tolerates the presence of oxygen but does not require it for growth. Instead, aerotolerant anaerobes use fermentation to survive. An example organism is lactobacillus.
