Pyrococcus furiosus is a heterotrophic, strictly anaerobic, extremophilic, model species of archaea. It is classified as a hyperthermophile because it thrives best under extremely high temperatures, and is notable for having an optimum growth temperature of 100 °C (a temperature that would destroy most living organisms).[1] P. furiosus belongs to the Pyrococcus genus, most commonly found in extreme environmental conditions of hydrothermal vents. It is one of the few prokaryotic organisms that has enzymes containing tungsten, an element rarely found in biological molecules.
Pyrococcus furiosus has many potential industrial applications, owing to its unique thermostable properties. P. furiosus is used in the process of DNA amplification by way of polymerase chain reaction (PCR) because of its proofreading activity. Utilizing P. furiosus in PCR DNA amplification instead of the traditionally used Taq DNA polymerase allows for a significantly more accurate process.[2] The thermodynamic stability of P. furiosus' enzymes is useful in the creation of diols for laboratory and industrial purposes. Certain superoxide dismutases found in P. furiosus can be introduced into plants to increase their tolerance in environmentally stressful conditions and ultimately their survival.[3]
