Thermophilic bacteria are a type of microorganism that thrive in high-temperature environments, typically between 45°C and 80°C (113°F to 176°F). They are commonly found in hot springs, deep-sea hydrothermal vents, and compost heaps. These bacteria have adapted to survive and reproduce in extreme heat, making them important for various ecological processes. These bacteria play a crucial role in the breakdown of organic materials in hot environments. They are also valuable in biotechnology, as their enzymes, known as thermostable enzymes, are used in industrial processes, such as bioremediation and the production of biofuels, due to their ability to function at high temperatures.
