Hyperthermophilic organisms have been the subject of intense study since their discovery in 1977 in the Galapagos Rift1. It was thought impossible for life to exist at temperatures a great as 100ºC until Pyrolobus fumarii was discovered in 19972. P. fumarii is an unicellular organism from the domain Archaea living in the hydrothermal vents in black smokers along the Mid-Atlantic Ridge2. These organisms can live at 106ºC at a pH of 5.52. In order to get energy from their environment these organisms are facultatively aerobic obligate chemolithoautotrophs, meaning these organisms build biomolecules by harvesting CO2 from their environment by using H2 as their primary electron donor and NO3- as its primary electron acceptor2. These organisms can even survive the autoclave, which is a machine designed to kill organisms through high heat and pressure2. These organisms have unique chemistry due to their extreme environment making them useful for biological research.
