Carbonyl-compounds as sustainable antifouling agents against Limnoperna fortunei

Abstract

In this study we report antifouling performance of thirty-one carbonyl compounds on mussel attachment. Some of these compounds were lab-synthesized by green-chemistry procedures and others were commercially acquired. One flavanone, one flavone, five chromones, one thioxanthone and one naphtoquinone were effective against mussel attachment and demonstrated no toxicity on the classic ecotoxicity-test with Artemia salina. These results encourage the use of certain carbonyl compounds to avoid fouling by L. fortunei.
