摘要：
A process for the production of paper, board and cardboard by draining a paper stock on a wire in the presence of at least one cationic polymeric retention aid and/or retention aid system with sheet formation and drying of the sheets, wherein an endo-β-1,4-glucanase is metered in an amount of from 0.00001 to 0.01% by weight, based on the dry paper stock, into the paper stock before the addition of the at least one cationic polymeric retention aid and/or retention aid system.
