Xylanase-assisted TCF bleaching of Eulaliopsis binata pulp

Research Journal of Chemistry and Environment
The chlorine-containing bleaching chemicals are completely replaced with other oxidative chemicals in total chlorine-free (TCF) bleaching. Moreover, the xylanase pretreatment of pulp improves the efficiency of oxidative chemicals during TCF bleaching. Brightness of E. binata ethanol-soda pulp increased by 2.5 and 1.4% (ISO) with A. flavus ARC-12 and S.

Using glycosidases to modify TCF bleached specialty sisal fibers

2014
Modifying fibers in order to upgrade them to dissolving grade involves several changes. Paper grade pulps can be used to yield this kind of raw materials, if the necessary modifications are carried out. Classic processes are capable of producing these changes. However, these classic processes present many drawbacks. In this direction biotechnology, and
