The DNA that codes for the enzyme is unlike the DNA for any known cellulase; it was traced back to a never-before-seen extremophile. "It's very strange to find one that doesn't fit into a well-defined category," Graham says.
SampleMatrix is based on extremophile biology in which organisms can survive long-term in a state of anhydrobiosis (life without water) and later be revived by rehydration.
The slideshows give an overall understanding of the extremophile research and the other sections provide excellent details and extend the information presented in the slideshows.
However, an enzyme from an extremophile survives the process.
And third, large-scale and automated experimental evolution in stochastic environments will be carried out with the micro-alga Dunaliella salina, an extremophile that thrives at high and variable salinities.
In real life, organisms with similar traits exist, such as the "extremophile" red alga Galdieria sulphuraria.
They currently are investigating which already-known exoplanets potentially might host extremophile life or habitable moons.
One such extremophile, Desulfonatronum thiodismutans, lives in Mono's mud without sunlight, getting energy from sulfates and other inorganic compounds.
If life began in extremophile conditions, as heat-loving archaea suggest, did life have to struggle hard to adapt to the radically different Earth of today?
Microbacterium hatanonis, an unusual "extremophile" (organisms inhabiting extreme environments).
This dramatic paleoceanographic event resulted in the establishment of harsh conditions (eutrophication, hypersalinity and anoxia) at the scale of a whole marine basin, which was lethal for most eukaryotes but allowed some extremophile prokaryotes to flourish.
Kane and Gelino are hard at work determining which already-discovered exoplanets might be candidates for extremophile life or habitable moons.
