Barophiles

Definition

Barophiles are microorganisms that thrive in high-pressure environments, such as deep-sea habitats. They have adapted mechanisms to survive and grow under extreme pressure conditions.

5 Must Know Facts For Your Next Test

1. Barophiles exhibit optimal growth at pressures much higher than atmospheric pressure.
2. They are commonly found in deep-sea environments, where pressures can exceed 1000 atmospheres.
3. Adaptations in barophiles include changes in membrane fluidity and protein structure to maintain function under high pressure.
4. Some barophiles are also psychrophilic, meaning they thrive in both high-pressure and low-temperature conditions.
5. Studying barophiles helps scientists understand extremophile survival strategies and the potential for life in extraterrestrial environments.
