Abstract
A method of evaluating marine paints for their ability to inhibit growth attachment of organisms to ship bottoms, to find chemicals toxic to marine fouling organisms and to permit rapid formulation of superior anti-fouling paints, using a bioluminescent microbiological assay. The bottoms of test vials are coated with a paint solution, the paint dried, and identical aliquots of an assay medium containing Pyrocystis lunula cells are added to the tests vials and to identical (but unpainted) control vials. After a preselected settling time, the vials are agitated and their light outputs measured and compared. Any dimuition of light in the test vials, relative to the control vials, in an indication of the anti-fouling characteristics of the paints being tested.
