Most living organisms cannot survive at temperature above 45°c How are some microbes able to live in habitats with temperatures exceeding 100°c
Some microorganisms are able to survive in extremely hot water springs or deep-sea hydrothermal vents because they have a minimal amount of free water in their body and have branched-chain lipids in their cell membrane reduces the fluidity of the membrane. The membrane of the cell protects the internal enzyme and organelles form desiccation (drying).
