The adhesion of microscopic marine algae to the walls of small containers of sea water has been studied. Infrared spectra of extracts and films of algae were analyzed and compared to spectra of known hydrocolloids. The studies indicate that the gels holding algae together in films are composed primarily of polysaccharide polymers similar to the seaweed hydrocolloids, carrageenan and alginic acid, but that the adhering layer of substance joining algae to foreign surfaces is mostly protein. Like all proteins in their native states, it is also a hydrocolloidal gel. Recognition that adhesive systems of marine fouling organisms are hydrocolloidal gels tells a great deal about their nature and delineates the most logical areas in which to undertake research on methods to prevent attachment of fouling organisms.
