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.

Abstract: The present invention relates to a method and compositions to inhibit bacter ia from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one fluorosurfactant to inhibit bacterial adhesion to the submergible surface. The present invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one fluorosurfactant to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the bacteria fouling organisms. The fluorosurfactant used in the method of the invention is an anionic or nonionic fluorosurfactant selected from: R f CH2CH2SCH2CH2CO2Li, (R f CH2CH2O)P(O)(ONH4)2, (R f CH2CH2O)2P(O)(ONH4), (R f CH2CH2O)P(O)(OH)2, (R f CH2CH2O)2P(O)(OH), R f CH2CH2O(CH2CH2O)x H, R f CH2CH2O(CH2CH2O)y H, R f CH2CH2SO3H, or mixtures thereof. The group R f is F(CF2CF2)3-8, X varies from 2-20, and y varies fro m 2-20.

Abstract: A method for increasing the effectiveness of a microbicide is described, wherein a microbicide and an N-alkyl heterocyclic compound are applied to a substrate or aqueous system subject to the growth of microorganisms. The N-alkyl heterocyclic compound is applied in an amount effective to increase the microbicidal activity of the microbicide. The N-alkyl heterocyclic compound has the formula: The variable "In" ranges from 5 to 17, and the heterocyclic ring defined by is a substituted or unsubstituted ring having four to eight members. Microbicidal compositions are described where the microbicide and the N-alkyl heterocyclic compound are present in a combined amount effective to control the growth of at least one microorganism. Methods for controlling the growth of microorganisms on various substrates and in various aqueous systems are also described. The combination of the microbicide and the N-alkyl heterocyclic compound is particularly useful as a microbicide in the leather industry, the lumber industry, the papermaking industry, the textile industry, the agricultural industry, and the coating industry, as well as in industrial process waters.
