    Abstract: Described is a method to inhibit bacteria from adhering to a submergible metal surface within an aqueous system, comprising the step of contacting the submergible surface with an amino methyl phosphonic acid or a salt thereof. The amino methyl phosphonic acid is a compound of the formula R1R2NCH2P(O)(OH)2, wherein, R1 and R2 are independently a C6-C14 alkyl group or H, but R1 and R2 are not both H, and the salt of an amino methyl phosphonic acid is an acid salt or quaternized acid salt. The method is suitable for submergible surfaces such as a ship hull, a boat hull, a marine structure, a tooth surface or a medical implant surface.
