Antifouling activity of natural compounds through bioassays and field immersion tests
Résumé
Any object immersed in seawater rapidly attracts the attention of marine fouling, causing severe problems on dynamic or static structures such as vessels, platforms, buoys and fishnets. Antifouling coatings generally comprise biocides or active compounds which could inhibit the settlement of marine micro- and macro-organisms. The most successful antifouling coatings based on tributyltin (TBT) compounds were banned by the International Maritime Organization (IMO). This study is part of ECOPAINT PACA project and focused on the activity of several active compounds on the adhesion of marine bacteria and on marine macroorganisms. In vitro and in situ tests were carried out on the active compounds and on coatings containing them.
