- adj. Describing ions (normally small, with a high charge density) that stabilize intermolecular interactions in water, especially by stabilizing hydrogen bonds
They then grew extremophiles on a medium supplemented with either chaotropic or kosmotropic solutes (which stabilize macromolecules rather than destabilize them).
Starting with four types of xerophilic fungi (aerobic extremophiles that thrive in environments with little water), the scientists found that at 30°C the fungi grew well in the presence of both chaotropic and kosmotropic solutes, but at 1. 7°C the fungi on media supplemented with chaotropes grew better than those on kosmotropes, with some of the latter showing zero growth.
