Cellulases, hemicellulases and pectinases are different exoenzymes that are involved in a wide variety of biotechnological and industrial applications. In the food industry these exoenzymes are used in the production of fruit juices, fruit nectars, fruit purees and in the extraction of olive oil among many others. The role these enzymes play in these food applications is to partially breakdown the plant cell walls and pectin. In addition to the role they play in food production, cellulases are used in the textile industry to remove excess dye from denim, soften cotton fabrics, and restore the color brightness of cotton fabrics. Cellulases and hemicellulases (including xylanases) are also used in the paper and pulp industry to de-ink recycled fibers, modify coarse mechanical pulp, and for the partial or complete hydrolysis of pulp fibers. Cellulases and hemicellulases are used in these industrial applications due to their ability to hydrolyze the cellulose and hemicellulose components found in these materials.
