Which of the Following is an Extreme Acidophile Found Anchored

Question

Which of the following is an extreme acidophile found anchored to deposits of pyrite ore in mines?
A) Thermus aquaticus
B) Pyrococcus abyssi
C) Ferroplasma acidarmanus
D) Picrophilus torridus
E) Thermoplasma acidophilum

Accepted Answer

Ferroplasma acidarmanus is an extreme acidophile frequently found in mines, where it colonizes sulfur-bearing minerals including pyrite (FeS2). It is capable of oxidizing ferrous iron (Fe2+) to ferric iron (Fe3+), thereby generating acid and contributing to the dissolution of the ore. The other options are also extremophiles but are not typically associated with pyrite deposits in mines.
