Question

7. Which of the following would be killed if placed in an environment that that apply. a) Obligate aerobe b) Microaerophile c) Facultative anaerobe d) Aerotolerant e) Obligate anaerobe totally lacks oxygen? Circle all A tube of thioglycollate broth (inoculated with a bacterial species and incubated) has turbidity only in the lower half of the broth. At the surface of the broth, the broth has a pink coloration. What is the oxygen requirement category of this species (circle one)? a) Aerotolerant b) Facultative anaerobe c) Microaerophile d) Obligate aerobe e) Obligate anaerobe 8. 9. A bacterial species grows well on an aerobic plate and grows just a little bit on an anaerobic plate. Based on this, you can categorize this species as (circle one): a) aerotolerant b) a facultative anaerobe c) an obligate aerobe d) a microaerophile e) an obligate anaerobe 10. Which of the following is an oxygen requirement category you could determine using thioglycollate broth, but NOT for these two different ways of assessing oxygen requirement categories!) (circle one) a) facultative anaerobe b) obligate anaerobe c) obligate aerobe d) microaerophile e) aerotolerant T using the combination of aerobic+anaerobic plates? (hint: try to draw expected results 11. In the absence of oxygen, what are TWO other ways that bacteria can make ATP (not including photosynthesis)? What is the difference between these 2 (hint your answer should include the phras "electron transport chain")?

Explanation / Answer

Answer:

7.

Obligate aerobe and microarophile will kills in the absence of air because they does not respire in the absence of air.

Hence,option (a,b ) is correct answer.

8.

Oxygen requirement category of this species is facultative anaerobe.

Hence, option (B) is correct answer.

9.

This species is a representative of facultative anaerobe.

Hence, option (B) is correct answer.

10.

The correct oxygen requirement catagory is facultative anaerobe.

Hence, option (a) is correct answer.
