Two cultures of a facultative anaerobe are grown in the same medium, but one culture is exposed to air and the other is maintained under anaerobic conditions. Which of the two cultures will contain more cells at the end of a week? Why?
Hydrogen Sulfide Production
1) Listen
In the lab you are testing a bacterium's oxygen requirement for growth. You grow
your bacterium in a test tube, without shaking at the appropriate temperature. The
next day you find that your bacterial culture is growing only at the top surface (ie at
the top of the tube closest to the cap) and not dispersed throughout the test tube.
What term would be used to describe the oxygen requirement of this bacterium?
O A) Obligate aerobe.
O B) Microaerophile.
O C) Anaerobe.
D) Obligate anaerobe.
E) Facultative anaerobe.
