Abstract
The effective application of a biocatalyst based on recombinant enzyme preparations obtained using Penicillium verruculosum is studied for the modification of marketable bleached sulfate hardwood cellulose. The effect of treatment with cellulase complex on the structure, morphology, and surface state of cellulose fibers is evaluated. After biocatalytic exposure, cellulose is shown to have an improved capacity for beating and the formation of bonds in paper sheets, along with greater strength than the initial cellulose. Application of the enzymatic modification of cellulose in the paper industry during biotechnological processes allows a range of problems in the efficient use of energy and resources to be solved.
