Control of biofilm formation in marine environment using Some N2O2 donor schiff bases

Abstract

The adhesion of microorganisms onto materials surface mediated by extracellular polymeric substances (EPS) lead to an important modification of the metal-solution interface. The requirement of modem civilization with the (lightened sense of environmental responsibilities and quality of life can be met by using some eco-friendly microbiocides with different spectra of activity. Some N202 donor schiff base compounds were synthesized and characterized by IR, NMR and ESR spectroscopy. These compounds were found effective in controling the growth of biofilm of E coli, Pseudomonas fluomscens and Thiobacillius thiooxidans on copper surface. The optimum concentration of these compounds are in the range of 1-10 ppm. Various electrochemical, microbiological and surface-analytical techniques were used to monitor the biofilm in the presence of microbiocides. © 1997 by NACE International.
