Some Crenarchaeotes Have Growth Optima Above the Boiling Point of Water

Question

Some crenarchaeotes have growth optima above the boiling point of water (at atmospheric pressure).

Accepted Answer

This statement is true. Some crenarchaeotes are able to grow at temperatures above 100°C (the boiling point of water at atmospheric pressure) in environments such as hydrothermal vents and hot springs. These organisms are referred to as thermophiles or hyperthermophiles.
