ABSTRACT:
The invention relates to the use of certain lipolytic enzymes such as cutinases and lipases in the manufacture of paper and paper products from recycled paper. Examples of such enzymes are derived from strains ofHumicola, Candida, FusariumandPseudomonas. By use of these enzymes, the problems relating to the so-called “stickies” derived from waste paper are reduced.
