archaea

Archaea

- prokaryotic and unicellular 

- thrive in ecological niches

extremeophile = organism that can surivive in an extreme condition 

obligate extremeophile = must have the conditions to survive

facultative extremeophile = can tolerate conditions 

thermophilic = live in hot condition 

problems for normal organisms 

- denaturation of molecules 

- membrane fluidity 

- solubilty of gases in liquids 

survival stratergies 

- different cell membrane

- different ester link - ether link 

- different proteins…
