In addition, some commercial cellulases such as FiberCare, FiberzymLBR and Celluclast 1.5L have also been used in the paper industry.
In addition, among the bacterial cellulases with commercial development potential, most of the produced endoglucanase mainly hydrolyzes amorphous cellulose, a few of the endoglucanase produced by Bacillus and Bacillus can hydrolyze microcrystalline cellulose, and the thermostable neutral cellulase produced by Bacillus campinasensis has been developed for use in pulping modifications and beater enzymes. The result is very good.
It can be said that the efficient application of enzymes in the pulp and paper industry can not only improve production efficiency, but also improve pulp quality and reduce energy and water consumption. However, the application of enzyme preparation in paper industry still has some problems, such as high cost, lack of stability, difficult mixing, insufficient residence time and unstable pulp quality.
However, with the improvement of molecular evolution and gene recombination technology, it will be conducive to improving the stability and production level of enzymes. In addition, the collaborative research of bioscientists and paper engineers is another key to promote the application of biotechnology in pulp and paper industry.
