are microorganisms that can survive under
great pressures. They live deep under the surfaces of the earth
or water. There are three kinds of these microorganisms: barotolerant,
barophilic, and extreme barophiles. Barotolerant extremophiles can
survive at up to 400 atmospheres below the
water or earth, but grow best in 1 atmosphere. Barophilic extremophiles
grow best at higher pressures up to 500-600 atmospheres. Extreme
barophiles do best at 700 atmosphere or more, but some survive at
1 atmosphere. The deep sections of the oceans are divided into layers
called atmospheres and are divided into zones called atmospheres.
The shallowest ocean atmosphere is at 1,000 feet below the surface
of the ocean, and the deepest ocean atmosphere is 7000 feet below
the surface of the ocean.
One atmosphere in the ocean is equal to 10
feet below the surface of the ocean. That means that barotolerant
extremophiles can survive at 4,000 feet, barophilic extremophiles
can survive at up to 6,000 feet, and extreme barophiles can survive
up to 7,000 feet below the surface of the ocean.
of the freezing temperatures that occur at the deepest parts of
the earth, barophiles are also considered to be psychrophiles. If
you put the two names together, you have a microorganism that can
stand up to both extremes.
