They have been used for the bioprospecting of molecules, such as enzymes.

Most of these enzymes are extracellular and their production extremophiles; filamentous in the laboratory has been carried out mainly under submerged culture conditions. Several fungi; mycology; studies showed that the cold-adapted enzymes exhibit a wide range in optimal pH (1.0–9.0) and psychrophiles; yeasts temperature (10.0–70.0 C). A myriad of methods have been applied for cold-adapted enzyme purification, resulting in purification factors and yields ranging from 1.70 to 1568.00-fold and 0.60 to 86.20%, respectively. Additionally, some fungal cold-adapted enzymes have been cloned and expressed in host organisms. Considering the enzyme-producing ability of microorganisms and the properties of cold-adapted enzymes, fungi recovered from Antarctic environments could be a prolific genetic resource for biotechnological processes (industrial and environmental) carried out at low or mild temperatures.
