Which one of the following microbes would grow best at pH 1-3.5?
A)Cyanobacteria in ocean water
B)Propionibacterium acnes bacteria on human skin
C)Acidithiobacillus ferrooxidans in the runoff from a copper mine

Question

Quizplus · Accepted Answer

Acidithiobacillus ferrooxidans is an acidophile, which means it thrives in acidic conditions. It is commonly found in acidic environments such as mine drainage water and can grow at pH levels as low as 0.5. Cyanobacteria in ocean water and Propionibacterium acnes on human skin do not grow well in such acidic conditions.
