C12N 9/00

US Classification:

162199, 162 5, 162 72, 510174

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 of and. By use of these enzymes, the problems relating to the so-called “stickies” derived from waste paper are reduced.

International Classification:

D21C003/20
D21C009/08

US Classification:

162/072000, 162/199000

Abstract:

Methods to control organic contaminants in fibers are described. One method involves contacting the fibers with a composition containing at least one esterase or lipase or both for a sufficient time and in a sufficient amount to control the organic contaminants present in the fibers. Preferably, the fibers are recycled fibers originating from a variety of sources such as old corrugated containers, old newsprint, mixed office waste, and the like. Resulting paper products formed from the processed fibers are also described as well as methods to make them.

US Classification:

162/072000, 162/100000, 162/189000

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 of Humicola, Candida, Fusarium and Pseudomonas. By use of these enzymes, the problems relating to the so-called “stickies” derived from waste paper are reduced.
