A thermophile is a type of microorganism that thrives in high-temperature environments, typically between 45°C to 80°C (113°F to 176°F). These organisms are often found in hot springs, geothermal vents, and other extreme habitats. Thermophiles have adapted to withstand and function optimally in these harsh conditions, making them of interest for various biotechnological applications, including enzyme production for industrial processes.
