Abstract

1. A method of treating a bisulphitic paper pulp having a high mean degree of polymerization of approximately 1,100, characterized in that, in order to give it the characteristics of a pulp for chemical purposes, there is caused to act upon the paper pulp an enzymatic preparation on a basis of fungic cellulases having a C1 activity and a Cx activity, a maximum activity in the pH range from 1.5 to 7.5, and at a temperature below 80 degrees C, the reaction medium being continually stirred the pH being maintained between 2 and 7 and the temperature below 80 degrees C during the action of the enzymatic preparation.
