Which Species Can Be Utilized in Biomining Because It Oxidizes

Question

Which species can be utilized in biomining because it oxidizes copper and iron sulfides?
A) Geobacter metallireducens
B) Sulfurospirillum barnesii
C) Haloferax volcanii
D) Acidithiobacillus ferrooxidans
E) Bacillus subtilis

Accepted Answer

Acidithiobacillus ferrooxidans is commonly used in biomining because it is capable of oxidizing both copper and iron sulfides. Geobacter metallireducens and Sulfurospirillum barnesii are not known for their ability to oxidize sulfides, while Haloferax volcanii and Bacillus subtilis are not commonly used in biomining.
