Next to cellulose, lignin is the second most abundant biopolymer, and the main source of
aromatic structures on earth. It is a phenolic macromolecule, with a complex structure which …

Lignin is a major component of lignocellulosic biomass and as such, it is processed in
enormous amounts in the pulp and paper industry worldwide. In such industry it mainly …

The molecular weight of lignin is a fundamental property that influences the recalcitrance of
biomass and the valorization of lignin. The determination of the molecular weight of lignin in …

The polydispersity of commercially available kraft lignins (KLs) is one of the factors limiting
their applications in polymer-based materials. A prerequisite is thus to develop lignin …

Lignin-first fractionation has become a new biorefinery target to obtain valuable lignin
monomers toward the complete utilization of lignocellulosic biomass, but increasing …

The reactivity and physicochemical properties of lignins are partly governed by their molar
mass distribution. The development of reliable standard methods for determination of the …

Determination of molecular weight parameters of native and, in particular, technical lignins
are based on size exclusion chromatography (SEC) approaches. However, no matter which …

Indulin AT biodegradation by basidiomycetous fungi, actinobacteria and commercial
laccases was evaluated using a suite of chemical analysis methods. The extent of microbial …

Efficient recovery of valuable materials from by-products of pulping has been a strong asset
to the environmental concern. The objectives of this research were to recovery and …

Several processes have been suggested to convert various types of lignocellulosic biomass
into lignin products and saccharides. This paper evaluates the suitability of an organosolv …
