to extreme EXTREMOPHILES

An extremphile is an organism that can strive under very extreme conditions. Extremophiles come in all shapes and sizes.

Alkaiphile-- an organism that grows best at high pH values, values above 9, often between 10-12 but cannot grow or grow only slowly at the neutral





Endoliths-- are organisms that live inside rocks or in pores between mineral grains, many are autrotophs (meaning they are able to make their own organic compounds by utilizing gas or dissolved nutrients from water moving through rock)

Xerophile-- an organism capable of growth at very low water activity, the environments range in temperature from very hot to very cold.
