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: ##STR1## The substituent R.sup.1 is a C.sub.8 -C.sub.20 alkyl group. The heterocyclic ring is a 5-8 membered heterocyclic ring where X is O, NH, or CH.sub.2. R.sup.2 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 in…
