Microbiologically influenced corrosion (MIC) and biofouling processesare mediated by microorganisms adhered to metal surfaces when embedded in a gelatinousmatrix called biofilm. Microbial adhesion processes lead to an importantmodification of the metal/solution interface, generally increasing the aggressivenessof the medium against the substratum.In thispaper, samples of NaA containing different quantities of Ag+1 and Zn+2 were prepared by cation exchange inorder to evaluate their antibacterial properties. The biocide cations Ag+1 and Zn+2 were hosted in the cavities of theordered aluminosiliceous framework. Minimum inhibitory concentration (mic)values corresponding to the exchanged zeolites and the antibacterial activityof these products against P. aeruginosa after incorporation in an epoxycoating formulation used for steel protection were determined.
