Bacterially derived biopolymers as wood adhesives

Chitosan: Emergence as potent candidate for green adhesive market

“…Hence research in this area is in great scope today. The effective bioadhesives are still under investigation and their bonding properties are actually an industrial challenge and an important research area [1]. * Carbohydrates were well explored as food additives and as potent adhesive candidate for many decades viz.…”

Wood production, wood technology, and biotechnological impacts

“…Other adhesive, non-toxic, and biodegradable carbohydrate polymers come from bacteria and fungi, for example glucans (pollulan) from higher basidiomycetes (Haars & Kharazipour 1998) and exopolysaccharides (EPS) from marine bacteria characterised by a special high water and low temperature resistance (Labare et al 1989, Weiner 1997. Qualities of bacterial exopolysaccharides provide to glued panels differ with the bacterial source they come from (Haag et al 2004(Haag et al , 2006. The anaerobic gramnegative bacteria Ruminococcus albus and Clostridium thermocellum degrade plant wastes by a range of cellolulytic enzymes, a property that is used in bio-ethanol production.…”

Preparation and Properties of Cassava Starch-based Wood Adhesives

“…However, most wood adhesives used in the wood products industry are based on non-renewable petrochemical resources, such as phenol/formaldehyde and polyurethane. Adhesives also contain volatile organic compounds (VOCs) and residual toxic chemicals, such as formaldehyde (Haag et al 2004(Haag et al , 2006. As such, this heavy dependence on petroleum and the harmful effects of emissive pollutants on human health have created an urgent need for environmentally friendly wood adhesives based on renewable resources.…”
