acidophiles from coal mine

  • Acidophiles: Definition & Example Video & Lesson Transcript

    Scientists have identified several areas, natural and manmade, that are acidic enough for acidophiles to thrive in. An example of a natural acidic environment are certain hot springs (containing sulfurous gas) at Yellowstone National Park. Other environments include volcanic sites, debris that remains from coal mining
