Question

Fe oxidizers can grow at pH<1. Give an example.

a) Acidithiobacillus ferrooxidans
b) E. coli
c) Saccharomyces cerevisiae
d) Pseudomonas aeruginosa

Answer 1

Acidithiobacillus ferrooxidans is an example of a Fe oxidizer that can grow at pH<1.

Step-by-step explanation:

Fe oxidizers that can grow at pH<1 are called acidophiles. Acidophiles are microorganisms that have the ability to survive and thrive in acidic environments. One example of an Fe oxidizer that can grow at pH<1 is Acidithiobacillus ferrooxidans, so the correct answer to the question is a) Acidithiobacillus ferrooxidans.
