Abstract
A process for treating lignocellulose pulp using a preparation containing at least one enzyme that produces a solubilizing action and, potentially, a hemicellulolytic action on lignin. The enzymes are derived from the bacterium Streptomyces viridosporus. This enzymatic treatment may be used for the separation of lignin from lignocellulose pulp in a procedure, for example, that complements a bleaching treatment.
