    Abstract: Compositions and methods for killing, preventing, or inhibiting the growth of microorganisms in an aqueous system or other systems are provided. The compositions can include at least one first cross-linkable polymer, at least one second cross-linkable polymer, and at least one cross-linking agent, wherein the water solubilities of each cross-linking polymer are different, such as by 10% to 100%. The compositions can further include at least one biocidal component. The compositions can be formulated to slowly release the biocidal component and/or the cross-linkable polymer, or rapidly release the biocidal component and slowly release the cross-linkable polymer. The compositions can be used to control algae.

    Abstract: The 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 sulfamic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one sulfamic acid or salt thereof 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 sulfamic acid used in the method of the invention has the formula R1R2NS(O)2(OH). In this formula, R1 and R2 are independently a hydrogen, a C4-C20 alkyl group or a cyclohexyl group. However, R1 and R 2 are not both hydrogen. Alternatively, R1 and R2, together with the N, may also form a 5-8 membered heterocyclic ring having the formula:In the heterocyclic ring, X is O, NH, or CH2. The salt of sulfamic acid can be an acid salt or quaternized sulfamic acid salt. The present invention also relates to a composition containing sulfamic acids or salts thereof useable in the above methods. The compositions comprise at least one sulfamic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

This method adds an effective amount of at least one amino methyl phosphonic acid or salt thereof 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 amino methyl phosphonic acid used in the methods of the invention has the formula R1R2NCH2P(O)(OH)2. In this formula, R1 and R2 are independently a C6-C20 alkyl group or a CH2P(O)(OH)2 group. However, R1 and R2 are not both a CH2P(O)(OH)2 group. Alternatively, R1 and R2, together with the N, may also form a 5-8 membered heterocyclic ring having the formula: In the heterocyclic ring, X is O, NH, or CH2. The salt of an amino methyl phosphonic acid can be an acid salt or a quaternized amino methyl phosphonic acid salt. The invention also relates to a composition containing amino methyl phosphonic acids or salts thereof and useable in the above methods. The compositions comprise at least one amino methyl phosphonic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.
