Q) What are the mechanisms for surviving extreme temperatures in microorganisms?

Does anyone know any websites with information on this? any suggestions or answers to the question will be appeciated...THANKS.

Hi
Well these organisms are called thermophiles, i.e. Organism who love high temperature. if you made search by entering Thermophiles you will get enough data on it.
Actually these organism have several mechanisms to servive in hot environment, for example The GC contect of these organism DNA is more then others mesophiles organisms, in addition these have unsaturated fatty acids instead of saturated fatty acids and protein are also modified in a way that they contain more SH groups so make more disulfide bonds and hence are more stable. this is actually the summary of modification. you can find some site and can study these in detail
best regards

And don't forget the organisms that live in extreme cold!

I can't post the URL for you, but there is a general article on Life Science DOT com about this.
