摘要:Lignin has a very complex structure, and this is partly due to the monomers being connected by many different types of covalent bonds. Furthermore, there are multiple covalent bonds between lignin and polysaccharides in wood, and it is known that the structure of lignin cova...

摘要:Abstract(#br)In this study, we pelletized four different pure polysaccharides represented cellulose - Avicel, hemicelluloses - locus bean gum mannan and beech xylan and other polysaccharides - apple pectin, and three woods - pine, spruce and beech. All were pelletized at 100...

摘要:Abstract(#br)The presence of covalent bonds between lignin and polysaccharides was investigated in dissolving pulps made with one-stage and two-stage acidic sulfite pulping for 100% pine heartwood raw material. The covalent bonds between lignin and pulp polysaccharides occur...

摘要:Abstract(#br)In this study we were mirroring suggested in vivo phenomena of lignin–hemicellulose complex formation in vitro , by cross-linking Norway spruce ( Picea abies ) galactoglucomannans, xylans and lignin moieties to high molecular weight complexes by laccase treatmen...

摘要:Abstract(#br)A novel mechanical pre-treatment method was used to separate the wood chips into fiber bundles in order to extract high molecular weight wood polymers. The mechanical pre-treatment involved chip compression in a conical plug-screw followed by defibration in a fi...

摘要:Abstract(#br)In this study, new wood-inspired films were developed from microfibrillated cellulose and galactoglucomannan–lignin networks isolated from chemothermomechanical pulping side streams and cross-linked using laccase enzymes. To the best of our knowledge, this is th...

摘要:Abstract(#br)Hemicelluloses as major components of plant cell walls are acetylated to different extents. The biological functions of acetylation are not completely understood but suggested that one reason is to decrease the microbial degradability of cell walls. Model seed galact...

摘要:Abstract(#br)Cellobiose dehydrogenase (CDH) is an extracellular enzyme produced by various wood-degrading fungi. It oxidizes soluble cellodextrins, mannodextrins and lactose efficiently to their corresponding lactones by a ping-pong mechanism using a wide spectrum of electron acc...

摘要:Abstract(#br)The fungus Rhizomucor pusillus grew well on flax ( Linum usitatissimum L.) stems and on pectin as the sole source of carbon. Of several fungal isolates from dew-retted flax, R. pusillus produced enzyme filtrates that were the most effective in retting flax as ev...

摘要:Abstract(#br)Cellobiose dehydrogenase (CDH) participates in the degradation of cellulose and lignin. The protein is an extracellular flavocytochrome with a b -type cytochrome domain (CYT cdh ) connected to a flavodehydrogenase domain (DH cdh ). DH cdh catalyses a two-electro...
