Crenarchaeotes whose optimal growth temperature is over 80°C are called
A) hyperthermophiles.
B) thermophiles.
C) extreme halophiles.
D) halophiles.

Question

Quizplus · Accepted Answer

Crenarchaeotes whose optimal growth temperature is over 80°C are considered to be hyperthermophiles, as they can survive and grow in extremely high temperatures. Thermophiles, on the other hand, have an optimal growth temperature of 50-80°C. Extreme halophiles and halophiles are archaea that require high salt concentrations to survive, but this characteristic is not directly related to their optimal growth temperature.
