method to inhibit bacterial adhesion on a submersible surface and method and composition to control biological contamination in an aqueous system

摘要

"Method for inhibiting bacterial adhesion on a submersible surface and method and composition for controlling biological incrustation in an aqueous system." the invention relates to a method for inhibiting bacterial adhesion to a submersible surface. "The method contacts the submersible surface with an effective amount of at least one sulfamic acid or salt thereof to inhibit bacterial adhesion to the submersible surface. the invention also relates to This method adds an effective amount of at least one sulfamic acid or salt thereof to inhibit bacterial adhesion to a submerged surface within the aqueous system.This method effectively controls biological incrustation without substantially killing. the encrusted organisms, the sulfamic acid used in the invention has the formula R ^ 1 r r ^ ^ ^cscscs o o o o o o o o o o o o o o o nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta nesta. C 1-4 or C 20 or a cyclohexyl group, however, R 1 and R 2 are not both hydrogen, alternatively R 1 and R 2, together those with n may form a 5-8 membered heterocyclic ring of formula (I). in the heterocyclic ring x is o, nh or ch ~ 2 ^. the salt of a sulfamic acid may be an acid salt or a quaternized sulfamic acid salt. The invention also relates to a composition containing sulfamic acid or salts thereof and usable in the above methods. The composition comprises at least one sulfamic acid or salt thereof in an amount effective to inhibit bacterial adhesion to submersible or submerged surfaces.
