LigninGehalt
Ligningehalt, or lignin content, refers to the proportion of lignin in plant materials, usually expressed as a percentage of dry matter. Lignin is a complex phenolic polymer that fills spaces in the plant cell wall among cellulose, hemicellulose, and other biopolymers. It provides structural support, contributes to water transport, and acts as a chemical barrier against pathogens. Because lignin is resistant to enzymatic degradation, its abundance strongly affects the digestibility of forage and the efficiency of biomass conversion.
Measurement of lignin content commonly uses the Klason method, which quantifies acid-insoluble lignin after sulfuric acid
Variation in lignin content occurs across species, tissues and age. Softwoods (gymnosperms) generally have higher lignin
Applications and implications: In the pulp and paper industry, high lignin content reduces pulping yield and
