Microbes that live at high temperatures in hot springs are known as thermophiles. They are able to thrive and survive in extreme heat conditions, typically between 60°C to 90°C (140°F to 194°F). Some examples of thermophiles found in hot springs include:
1. Thermus aquaticus: This bacterium is commonly found in hot springs and is known for its ability to withstand high temperatures. It produces an enzyme called Taq polymerase, which revolutionized the field of molecular biology as it is used in the polymerase chain reaction (PCR) technique.
2. Sulfolobus: These are archaea that thrive in extremely acidic hot springs, often above 80°C (176°F). They are characterized by their ability to oxidize sulfur and produce sulfuric acid.
3. Pyrolobus fumarii: This hyperthermophilic archaeon lives in the deep-sea hydrothermal vents and can withstand temperatures up to 113°C (235°F). It is one of the most heat-tolerant organisms known.
4. Thermococcus: These are hyperthermophilic archaea found in marine hot springs, such as hydrothermal vents, where temperatures can reach up to 400°C (752°F).
5. Aquifex aeolicus: This bacterium is found in hot springs and is known for its ability to utilize hydrogen as an energy source. It can survive in temperatures up to 95°C (203°F) and is considered one of the most heat-tolerant bacteria.
These thermophiles have unique adaptations, such as heat-stable enzymes and protective cell membranes, which allow them to survive and thrive in the extreme conditions of hot springs.
