Cold adaptation in Arctic and Antarctic fungi
Growth and activity at low temperatures and possible physiological and ecological mechanisms, underlying survival of fungi isolated from the cold Arctic and Antarctic are reviewed here. Physiological mechanisms conferring cold tolerance in fungi are complex; they include increases in intracellular t...
