Polymerization involves model compounds and lignin fragments having a free phenol hydroxyl.
Ph. sanguinea , Lignin destruction is accompanied by reactions of demethylation and oxidation. The latter affect side chain C and C atoms. Biodegradation and functionalization of lignin facilitate lignin recovery during delignification. The goal of the present research is a possible use of exoenzymes of basidial fungi for kraft hardwood cellulose bleaching. Dynamics of the development of ligninolytic and carbohydrase activities show the enzyme ratio to depend on the culture age and the presence of an aromatic inducer in the nutrient medium.
