A bioadhesive composition for bonding together adjacent surfaces of wood comprises a microbially-produced fermentation residue containing adherent microbial cells and glycocalyx. This residue finds particular application as a replacement for a significant amount of phenol-formaldehyde (PF) or other conventional adhesive component commonly used in the production of plywood and other wood products.

Wood adhesives containing solid residues of biomass fermentations

Water-resistant, protein-based adhesive dispersion compositions and methods for preparing them are provided. The adhesive dispersions are prepared by copolymerizing a denatured vegetable protein, such as soy flour, that has been functionalized with methylol groups with one or more reactive comonomers, and preparing an acidic dispersion of the adhesive. The adhesive dispersions exhibit superior water resistance, and can be used to bond wood substrates, such as panels or laminate, or in the preparation of composite materials.
