Sulphur Caldron. . Ten times more acidic than lemon juice, Sulphur Caldron sits on the edge of one of the most active areas of Yellowstone's buried volcano. Sulphur-rich gasses rise furiously here, filling Sulphur Caldron with sulfuric acid. Incredibly, this muddy pool is teeming with life!
Home Sweet Home , Billions of thermoacidophiles thrive in Sulphur Caldron. They convert the pool's hydrogen sulfide gas into sulfuric acid. , The sulfuric acid breaks soil and rock into mud, making this spring a very muddy home.
What is a Thermoacidophile? , Thermo = Heat , Acid = Acidic , Phile = Love , Microorganisms that "love" to live in an extremely hot, acidic environment are called "thermoacidophiles."
pH Scale Basics , If you have ever had "heart burn" from eating acidic foods and used an antacid to relieve the pain, you can easily understand pH basics. , "pH" means "power of hydrogen." Acids release hydrogen ions, and alkaline solutions remove them. Acids and bases neutralize each other. , Thermoacidophiles thrive in an acidic environment that would be deadly to humans. Sulphur Caldron's microbes live in a pool that is almost as acidic as battery acid!
