Halophiles are organisms that thrive in high salt concentrations. The adaptations of halophile organisms to their environment are:
(a) The integrity of non-halophile macromolecules is compromised, and the flow of water out of the cell produces a Turgor effect. • (b) Moderate halophiles maintain their structures via the synthesis of compatible organic solutes. • (c) Extreme halophiles maintain their structures via equilibration of cellular and environmental salt concentrations.
