highlignin
Highlignin is a term used to describe plant biomass or tissues that have an elevated lignin content in the secondary cell wall. Lignin is a complex aromatic polymer that, along with cellulose and hemicellulose, provides mechanical strength, hydrophobicity, and resistance to degradation. Lignin content and composition vary widely among species, tissues, developmental stages, and environmental conditions; highlignin materials exhibit lignin levels that are higher than the species’ average.
Impact on processing: In pulp and paper production and in biofuel pathways, highlignin biomass tends to be
Measurement and modification: Lignin content is commonly quantified by the Klason method (acid-insoluble lignin) or spectroscopic
Terminology: The term highlignin is not a formal scientific category; it appears in some literature and industry
