Summary

In 1969, Thomas Brock showed through his researches that certain microorganisms can live at high temperature, even over 100°C. These are bacteria thermophiles which have colonized the ecological niches next to terrestrial and underwater hot springs.
Daniel Prieur, a CNRS microbiologist, recounts the researches of the mission called Microsmoke (November and December 1995) which explored troughs in the Atlantic Ocean at 3.500 meters deep.
Bacteria Thermophiles are maybe one of the first form of life which has appeared on Earth. Their resistance to very high pressures and temperatures allows the researchers to explore extreme conditions where life is still available.
There is a long version of this film, for a more specialized public, entitled “Life at High Temperature”.
