Unique properties of hyperthermophilic archaea

This article discusses the Unique properties of hyperthermophilic archea. Hyperthermophiles are organisms that can live at temperatures ranging between 70 and 125 °C. They have been the subject of intense study since their discovery in 1977 in the Galapagos Rift. It was thought impossible for life to exist at temperatures as great as 100 °C until Pyrolobus fumarii was discovered in 1997. P. fumarii is an unicellular organism from the domain Archaea living in the hydrothermal vents in black smokers along the Mid-Atlantic Ridge. These organisms can live at 106 °C at a pH of 5.5. In order to get energy from their environment these organisms are facultatively aerobic obligate chemolithoautotrophs, meaning these organisms build biomolecules by harvesting carbon dioxide (CO2) from their environment by using hydrogen (H2) as the primary electron donor and nitrate (NO3−) as the primary electron acceptor. These organisms can even survive the autoclave, which is a machine designed to kill organisms through high temperature and pressure. Because hyperthermophiles live in such hot environments, they need to have DNA, membrane and enzyme modifications in order to withstand the intense thermal energy. Such modifications are currently being studied to better understand what allows an organism or protein to survive such harsh conditions. By learning what allows these organisms to survive such harsh conditions, researchers will be better able to synthesize molecules that are harder to denature that can be used in industry.
