Industrial Enzymes

Xylanase:
Xylanases are able to degrade the hemicellulose present in the pulp without affecting the cellulose. Enzymatic treatment has been shown to enhance various physical properties of paper, including viscosity, tensile strength, breaking length, and tear factor. In addition, biobleaching with xylanases softens the fibres, allowing them to undergo further chemical bleaching. Microbial xylanolytic enzymes are used in different industrial application such as food, feed and paper industry (pulp bleaching).

Proteases:
Different type of proteases like acidic protease, neutral protease and alkaline protease play an important role in the food, feed, beverage, textile, leather and detergent industry. Alkaline proteases, now apply in detergent industry as a detergent additive for destaining process and enzymatic dehairing of hide. It is suggested as an environmentally friendly alternative to the conventional methods. In leather industry the conventional (lime sulphide) method are an old technique used sulfide and lime that become an environmentally objectionable, hence now days the industries are attracting towards enzymatic (alkaline protease) methods of dehairing of hides and skins.

Amylase:
Amylases are one of the main enzymes used in industry. Such enzymes hydrolyze the starch molecules into polymers composed of glucose units. α-Amylases can be obtained from plants, animals and microorganisms. However, enzymes from fungal and bacterial sources have dominated applications in industrial sectors. Amylases have potential application in a wide number of industrial processes such as food and beverage, fermentation, textile and pharmaceutical industries.

Lipase:
Lipases that act on carboxylic ester bonds, the physiologic role of lipases is to hydrolyze triglycerides into diglycerides, monoglycerides, fatty acids, and glycerol. These enzymes are widely found throughout the animal and plant kingdoms, as well as in molds and bacteria. In addition to their natural function of hydrolyzing carboxylic ester bonds, lipases can catalyze esterification, interesterification, and transesterification reactions in non aqueous media. This versatility makes lipases the enzymes of choice for potential applications in the food, detergent, pharmaceutical, leather, textile, cosmetic, and paper industries. The most significant industrial applications of lipases have been mainly found in the food, detergent, and pharmaceutical sectors.
