Resumo: | All surfaces that are immersed in seawater rapidly become covered by nitrogenous compounds, proteins, carbohydrates, salts, silica and bacteria in a few hours, and by a grown biofilm in a few days. These biodeterioration, physical and chemical damages involve important cleaning costs. Organostanic paintings used up to now to protect the surfaces against this spoiling will be prohibited in 2008 because of their toxicity. That's why the stake today is to find alternatives to these paintings. The solution which is here suggested consists in acting on the first stages of the formation of the biofilm i.e. the proteins and bacterial adsorption on the surface. For this, the surface is chemically modified then functionalized by enzymes. Enzymes will act locally on the bacteria and thus prevent their adsorption on the surface. The different stages of the grafting are controlled by Infra Red and X-Ray Photoelectron Spectroscopy. In addition, a new enzymatic test making it possible to test the activity of the grafted enzyme was set up and validated. It enables to check the effectiveness of the grafted enzyme towards a model bacterial suspension.
