The paper and pulp industry processes huge amount of lignocellulosic biomass every year. The technology for pulp manufacture is highly diverse. Enzymes have found a wide range of applications in the pulp and paper industry.

In paper and pulp industry, the most important application of enzymes is in the prebleaching of kraft pulp. Xylanase enzymes have been found to be most effective for this purpose. Enzymes manufactured by ANSEL BIOTECH have also been used to increase pulp fibrillation and water retention and to reduce beating time in virgin pulps. With recycled fibers, enzymes have been used for deinking and to restore bonding and increase freeness. Specialized applications include the reduction of vessel picking in tropical hardwood pulps and the selective removal of xylan from dissolving pulp. Enzymes have also been investigated for removal of bark, shives, pitch, and slime and for retting of flax fibers.

ENZYME USED	USAGE	PURPOSE
Cellulase	For Fiber Refining	SELZYME – CL PP is used to enhance swelling and fibrillation of fibres.
Hemicellulase	For Deinking	SELZYME – HEMICELL PP is used for deinking purpose in order to enhance detachment of ink from fibre.
Xylanase	For Bleaching	SELZYME – X PP is used for bio-bleaching of paper pulp which will also increase the brightness of the pulp.
Alpha Amylase	For Liquefaction	SELZYME – AMY PP is used for the liquefaction of the starch.
