Enzymatic treatment of pulp to increase strength using truncated hydrolytic enzymes |
摘要 |
Papermaking fibers are treated with certain hydrolytic enzymes, specifically including cellulases, such as truncated endo-glucanases, which have been freed of their cellulose binding domain, to generate aldehyde groups at or near the surface of the fibers. Paper sheets made from the resulting fibers exhibit improved strength characteristics relative to paper sheets made from untreated fibers.
