What temperature range is optimal for mesophiles?

Mesophiles are organisms that thrive in moderate temperature ranges, typically between 20 to 40 degrees Celsius. This optimal temperature range is conducive to their growth and metabolic processes. At these temperatures, cellular functions, enzyme activities, and reproduction rates are maximized, allowing mesophiles to flourish in environments such as soil and the human body.

The other temperature ranges presented do not align with mesophilic growth. Temperatures below 20 degrees Celsius are generally too cold for mesophiles, while temperatures above 40 degrees Celsius often lead to stress or denaturation of vital cellular components. Similarly, ranges above 60 degrees Celsius are typically aligned with thermophiles, organisms that have adapted to thrive in high-temperature environments. Thus, the selection of the 20 to 40 degrees Celsius range accurately reflects the characteristics of mesophilic organisms.
