Abstract: A method of producing a fiberboard having improved mechanical properties such as water uptake (swelling), tensile strength perpendicular to the surface (IB), modulus of elasticity (MOE), and modulus of rupture (MOR) of the resulting fiberboard. The method includes providing a slurry of lignin-containing wood fiber material, adding a phenol oxidizing enzyme system, forming a mat of the wood fiber material, and pressing the formed mat by applying heat and pressure.

Abstract: The xylanase is characterized by several partial amino acid sequences and is immunoreactive with an antibody raised against a purified xylanase derived from Humicola insolens, DSM 1800. This xylanase preparation is practically free of cellulase xylanase and is well suited for treatment of paper pulp, as a baking agent and as an additive to fodder.

Abstract: Resin can be hydrolyzed enzymatically during the peroxy bleaching (e.g. with hydrogen peroxide) commonly used in pulp manufacture and the use of lipase in the manufacture of CTMP-fluff will afford several significant advantages, such as a pronounced reduction in fats, low time-consumption, since the process can be carried out in less than one calendar day, no losses in brightness or yield, or only marginal brightness and yield losses, and low handling costs. The enzyme treatment during bleaching necessitates little or no change of commonly used bleaching conditions. As a further advantage, the peroxy bleaching is mostly made at alkaline pH, whereby the liberated fatty acids remain ionized and can thus easily be removed from the pulp during subsequent washing.

Abstract: Resin can be hydrolyzed enzymatically during the reductive bleaching (e.g. with sodium dithionite) commonly used in pulp manufacture. The enzyme treatment necessitates little or no change of commonly used bleaching conditions.
