Thermoprotei

Thermoprotei is a class of microorganisms within the domain Archaea, known for living in extremely hot environments like hot springs and deep-sea vents. These microbes thrive at high temperatures—often above 80°C (176°F)—and are adapted to survive under intense heat and sometimes acidic conditions. They play important roles in Earth's ecosystems by participating in processes like nutrient cycling and energy flow. Due to their unique biochemistry and resilience, Thermoprotei are of interest in scientific research, including studies on early life forms and potential applications in biotechnology.
