Summary

Ice-active substances (IASs), i.e. macromolecular substances that modify the shape of growing ice crystals, were previously found to be associated with various terrestrial and aquatic photosynthetic organisms from Antarctica, but their chemical nature and function were unknown. The study investigated the ice-binding properties of IASs. The results raise the possibility that the IASs increase freezing tolerance of their respective organisms by preventing the recrystallization of ice.
