Biodeinking, of various recycled fibers but the main enzymes used are cellulases and hemicellulases. Extensive research has been undertaken that demonstrates the application of enzymes and their effectiveness. Different mechanisms for ink removal by enzymes have also been proposed. Operating conditions must be optimized for successful deinking.

Biodepitching,n exposed part of the paper machine can degrade product quality and can impair the production process. Solving these problems effectively is a major concern of pulp and paper industry. Any treatment, which reduces the amount of pitch formation, could lead to savings in downtime and production costs.

Bioretting,ocess of retting. Two methods employed for retting flax at commercial levels using pectinolytic microorganisms are water- and dew-retting. Water-retting traditionally depends upon anaerobic bacteria, such as . spp., that live in lakes, rivers, ponds, and vats to produce pectinases and other enzymes

Biopulping,d number of white-rot fungi to colonize and degrade selectively the lignin in wood, thereby leaving cellulose relatively intact. This process appears to have the potential to overcome some problems associated with conventional chemical and mechanical pulping methods. Biopulping is an environmentally

Biobleaching,c type, particularly xylanases, are used commercially for pulp bleaching. Xylanase enzymes have proven to be a cost-effective way for mills to realize a variety of bleaching benefits including reducing AOX discharges primarily by decreasing chlorine gas usage, debottlenecking mills limited by chlori
