Ecological problems associated with current antifouling technologies have increased interest in the natural strategies that marine organisms use to keep their surfaces clean and free from fouling. Bacteria isolated from living surfaces in the marine environment have been shown to produce chemicals that are potential antifoulants. Active compounds from the cells and culture supernatant of two bacterial strains, FS-55 and NudMB50-11, isolated from surface of the seaweed, Fucus serratus, and the nudibranch, Archidoris pseudoargus, respectively, were extracted using solid phase extraction. The extracts were combined with acrylic base paint resin and assayed for antifouling activity by measuring their ability to inhibit the growth of fouling bacteria. These formulations were found to be active against fouling bacteria isolated from marine surfaces. The formulation of antifouling paints that incorporate marine microbial natural products is reported here for the first time. This is a significant advance towards the production of an environmentally friendly antifouling paint that utilizes a sustainable supply of natural biodegradable compounds.
