11 Role of microbial oxidative enzymes in the pulp and paper industry
-
Nitin Kumar
Abstract
The traditional methods of pulp and papermaking consume vast amounts of water, energy, and chemicals. Microbial enzymes can provide an effective solution that lowers the environmental impact by reducing the need for electricity, water, and harsh chemicals. The use of microbial enzymes is revolutionizing the way pulps and fibers are processed. Xylanases reduce the need for chemical usage in bleaching processes, cellulases improve fiber texture, increase drainage, and facilitate ink removal, lipases lower the amount of pitch, and lignin-degrading enzymes remove lignin from pulps. In the pulp and paper industry, oxidative enzymes are used to improve various processes, such as pulp bleaching, deinking, and wastewater treatment. Some commonly used oxidative enzymes in the pulp and paper industry include lignin-degrading enzymes, peroxidases, catalases, manganese peroxidases, etc. The specific type of oxidative enzyme used in a particular application depends on the type of process being performed and the substrate being targeted. In some cases, a combination of different oxidative enzymes may be used to achieve the desired result. The use of oxidative enzymes in the pulp and paper industry has the potential to lead to cleaner, more efficient processes with a lower environmental impact. This chapter explores the prospects and advancements of different oxidative enzymes in various areas of the pulp and paper industry.
