Abstract (en)
[origin: WO2019229228A1] The present invention relates to treatment of dissolving pulp with a lytic polysaccharide monooxygenase. The lytic polysaccharide monooxygenase treatment results in reduced viscosity and/or improved viscosity control in the dissolving pulp production process and/or 5 increased reactivity of the dissolving pulp.
