METHOD OF ENZYMATIC TREATMENT OF A SOLID LIGNOCELLULOSIC MATERIAL

摘要

The invention concerns a method of treating a solid lignocellulosic material (10) in which said solid lignocellulosic material (10) is subjected to a treatment, called a mechano-chemical treatment (1), of mixing and chemical degradation of said solid lignocellulosic material (10) in such a way as to form an intermediate composition having a hydrated lignocellulosic material of which the enzymatic digestibility is increased relative to the digestibility of the solid lignocellulosic starting material (10), then; the hydrated lignocellulosic material is subjected to a treatment, called a mechano-chemical treatment (2), in which a dispersion is formed, called an aqueous dispersion, of the hydrated lignocellulosic material (10) in an aqueous composition, said aqueous dispersion comprising at least one enzyme for degrading said hydrated lignocellulosic material (10).
