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 ionene polymer and a salt of dodecylamine in a combined amount effective 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 ionene polymer and a salt of dodecylamine in a combined amount effective 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 present invention also relates to compositions containing an ionene polymer and a salt of dodecylamine and useable in the above methods. The compositions comprise an ionene polymer and a salt of dodecylamine in a combined amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.
