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.

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 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: RfCH2CH2SCH2CH2CO2Li, (RfCH2CH2O)P(O) (ONH4)2, (RfCH2CH2O)2P(O) (ONH4), (RfCH2CH2O)P(O) (OH)2, (RfCH2CH2O)2P(O) (OH), RfCH2CH2O (CH2CH2O)xH, RfCH2CH2O(CH2CH2O)yH, RfCH2CH2SO3H, or mixtures thereof. The group Rf is F(CF2CF2)3-8, x varies from 2-20, and y varies from 2-20. The present invention also relates to a compositions containing a fluorosurfactant and useable in the above methods. The compositions comprise at least one fluorosurfactant in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.
