| Biofilm formation on surfaces immersed in sea water induces equipment damages. Recently, studies focused on the environmental impact of antifouling paints have shown that some active chemical compounds are harmful to the aquatic environment. Hence, it appears fundamental to study physico-chemical interactions existing between marine bacteria and various substrata to conceive new ecological products or antifouling processes. First, we model an artificial primary organic film, formed by the adsorption of BSA and polysaccharide, as close as the one formed in natural seawater. This organic film is heterogeneous (only 42% of the surface is covered) and organic adsorption occurs in a multi-layer scheme, molecules bounded each others by calcium and magnesium... |
