how are microbes (archaebacteria) able to flourish in hot springs and hydrothermal vents where temp. far exceed 100 deg C ?

Microbes such as archaebacteria which can survive in very high temperatures are called thermophiles. They can survive in deep-sea hydrothermal vents or hot springs due to their structural difference present in the properties of the lipid bilayer. The compactness in their proteins and the presence of high level of saturated fatty acids helps them to withstand temperature far beyond 100 degree Celsius without denaturing the enzymes present inside them.
