The research program represented a consolidation of three research programs 1 the examination of the lipid metabolism of the Archaebacteria from the hydrothermal vents, 2 the analysis of the initial microfouling community using ultrasensitive signature lipid biomarker techniques, and 3 the development of an assessment program for the detection of microbial biofouling on painted surfaces for the Antifouling Coatings Development Program. Significant progress was made in detecting and monitoring the hydrothermal vent microbiota from in situ samples and in bioreactors. New methodologies for significantly reducing chemical noise were developed for assessing the initial microfouling film and a test system for detecting biofilm formation and sublethal toxicity on the test surfaces with the initial microfouling organism Pseudomonas atlantica.
