Most living organisms cannot survive at temperature above 450C. How are some microbes able to live in habitats with temperatures exceeding 1000C?

For survival of an organism temperature plays an important role. In most animals, the metabolic reactions occur in a narrow range of temperature such organisms are called stenothermal. The enzymes in such organisms get denatured, if they are placed in temperature above it’s normal range. Some microbes can survive temperature exceeding 100° C, because they have adapted to such high temperature due to the presence of thermos-resistant enzymes (these enzymes do not get destroyed or denatured at high temperature).
