Industrial applications of enzymes isolated from extremophiles.

Extremophiles	Habitat	Enzymes	Representative applications
Thermophile	High temperature	Amylases Xylanases Proteases DNA polymerases	Production of glucose, fructose for sweeteners Paper bleaching Used in baking, brewing, and as detergent additive Genetic engineering
Psychrophile	Low temperature	Proteases Dehydrogenases Amylases	Cheese maturation Biosensors Polymer degradation in detergents
Acidophile	Low pH	Sulfur oxidation	Desulfurization of coal
Alkalophile	High pH	Cellulases	Polymer degradation in detergent
