摘要： The invention provides protein adhesives, and methods of making and using such adhesives. The protein adhesives contain a protein-bonding agent and plant protein composition, such as an isolated water-soluble protein fraction or ground plant meal obtained from plant biomass. The protein-bonding agent can be an anhydride compound, carboxylic acid compound, carboxylate salt compound, or combinations thereof. The protein adhesives are useful in bonding together lignocellulosic materials and other types of materials.

摘要： Disclosed herein are cellulase compositions useful as papermaking performance additives for improving paper dry strength of a paper product and reducing refining energy in papermaking processes, and improving paper production. These cellulase compositions are formulated using cellulase, papermaking contaminant control polymers, protein stabilizers and cellulase enhancers. These cellulase compositions measure higher in endo-cellulase activity with better stability than conventional cellulase, and have shown differentiating performance in improving paper dry strength properties versus cellulase alone.

摘要： The invention relates to enzymes having xylanase, mannanase and/or glucanase activity, e.g., catalyzing hydrolysis of internal β-1,4-xylosidic linkages or endo-β-1,4-glucanase linkages; and/or degrading a linear polysaccharide beta-1,4-xylan into xylose. Thus, the invention provides methods and processes for breaking down hemicellulose, which is a major component of the cell wall of plants, including methods and processes for hydrolyzing hemicelluloses in any plant or wood or wood product, wood waste, paper pulp, paper product or paper waste or byproduct. In addition, methods of designing new xylanases, mannanases and/or glucanases and methods of use thereof are also provided. The xylanases, mannanases and/or glucanases have increased activity and stability at increased pH and temperature.
