Mesophiles vs. Thermophiles: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on February 23, 2024
Mesophiles are microorganisms thriving at moderate temperatures, typically between 20°C and 45°C. Thermophiles are microorganisms that thrive at high temperatures, often between 45°C and 80°C.
Key Differences
Mesophiles are microorganisms that grow optimally at moderate temperatures, commonly found in environments like soil and the human body. Thermophiles, in contrast, prefer much higher temperatures, thriving in places like hot springs and geothermal areas.
The enzymes of mesophiles function best at their moderate optimum temperature range. On the other hand, thermophiles have adapted enzymes and proteins that remain stable and functional at high temperatures.
In terms of habitat, mesophiles are often found in everyday environments, including freshwater and terrestrial ecosystems. Thermophiles are typically found in extreme environments, such as volcanic areas and deep-sea hydrothermal vents.
Mesophiles include many of the common bacteria and fungi that interact with humans, both beneficially and pathogenically. Thermophiles, however, are often involved in industrial processes due to their ability to withstand high temperatures.
The cell structures of mesophiles are suited to moderate conditions, whereas thermophiles have unique adaptations, like heat-stable lipids in their cell membranes, to survive in high-temperature environments.
