    Abstract: The present invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one sulfonamide 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 sulfonamide to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The sulfonamide used in the method of the invention has the following formula:The present invention also relates to a composition containing the sulfonamides and useable in the above methods. The compositions comprise at least one sulfonamide in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

    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 to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one N-alkyl heterocyclic compound 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 N-alkyl heterocyclic compound to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The N-alkyl heterocyclic compound used in the method of the invention has the following formula: The substituent R1 is a C8-C20 alkyl group. The heterocyclic ring is a 5-8 membered heterocyclic ring where X is O, NH, or CH2. R2 is methyl, hydroxymethyl, or hydroxyethyl. The integer n ranges from 0 to 3. The present invention also relates to a composition containing N-alkyl heterocyclic compounds and useable in the above methods. The compositions comprise at least one N-alkyl heterocyclic compound in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.
