Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Lignins are particularly important...

The term "lignin characterization" (or "lignin analysis") refers to a group of activities within lignin research aiming at describing the characteristics...

Lignin-modifying enzymes (LMEs) are various types of enzymes produced by fungi and bacteria that catalyze the breakdown of lignin, a biopolymer commonly...

which connect many of the constituents of lignin. Sulfonated lignin (SL) refers to other forms of lignin by-product, such as those derived from the much...

both digest a tree's cellulose and hemicellulose but not its lignin; white rot digests lignin as well. The residual products of decomposition from fungal...

the unwanted lignin, but not the cellulose fibres. In the biopulping process, the fungal enzyme lignin peroxidase selectively digests lignin to leave remaining...

In enzymology, a lignin peroxidase (EC 1.11.1.14) is an enzyme that catalyzes the chemical reaction 1,2-bis(3,4-dimethoxyphenyl)propane-1,3-diol + H2O2...

The Kappa number is an indication of the residual lignin content or bleachability of wood pulp by a standardized analysis method. The Kappa number is determined...

(4-allyl-2-methoxyphenol). Today, artificial vanillin is made either from guaiacol or lignin. Lignin-based artificial vanilla flavoring is alleged to have a richer flavor...

lignin(MWL), formaldehyde-protected lignin (FPL) and acetone-protected lignin adhesives that were prepared with lignins separated under either mild conditions...

a chemical pulping process separates lignin from cellulose fibre. A cooking liquor is used to dissolve the lignin, which is then washed from the cellulose;...

leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the...

organosolv is a pulping technique that uses an organic solvent to solubilise lignin and hemicellulose. It has been considered in the context of both pulp and...

hemicellulose, and an aromatic-rich polymer called lignin. Any biomass rich in cellulose, hemicelluloses, and lignin are commonly referred to as lignocellulosic...

cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary...

mineralization. There needs to be a balance between the decay of cellulose and lignin and mineral templating for cellular detail to be preserved with fidelity...

polymers of hardwoods are cellulose, hemicellulose, and lignin. The constituents of hardwood lignin differs from those included in softwood. Sinapyl alcohol...

The compound is present in wood smoke, resulting from the pyrolysis of lignin. The compound contributes to the flavor of many substances such as whiskey...

of various biopolymers, tannins, lignin, suberin and polysaccharides. Up to 40% of the bark tissue is made of lignin, which forms an important part of...

134. Biosynthesis of lignin (including the delineation of pathways), structure of lignin, chemistry of lignin, reactions of lignin. Analysis of the impacts...

which lignin and hemicellulose are separated from cellulose fiber for the production of pulp. The white liquor breaks the bonds between lignin and cellulose...

lignols, are the source materials for biosynthesis of both lignans and lignin and consist mainly of paracoumaryl alcohol (H), coniferyl alcohol (G) and...

sulfide (Na2S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, and cellulose. The technology entails several steps, both...

from the kraft process when digesting pulpwood into paper pulp removing lignin, hemicelluloses and other extractives from the wood to free the cellulose...
