Modification of lignins and lignans by laccase

Lignins are biopolymers that may be converted into functional materials by enzymatic treatments by oxidizing the phenolic groups into radicals. These radicals are extremely reactive and may couple with other reactant radicals....

Potential of laccases to modify lignings of various origins

Lignin and related aromatic compounds provide an important source of raw material that may be converted into value-added products by combining chemical and enzymatic modification methods. The aim of the present study was to reveal the potential of la...

Novel organosolv delignification method

LGF pulping process uses phosphinic acid as a catalyst in delignification of lignocellulosic material carried out in selected organic solvent. The process can be used for production of lignin rich, strong, reactive fibres with high yield or for fract...

Technical lignins

Increased need to exploit the biomass raw materials completely has raised the need to develop valorisation processes for new types of raw materials, typically side-stream fractions from forestry, agro and food industries. Lignin residues formed in no...
