Abstract : This report describes research into the role of bacteria in marine corrosion processes. During the past year we have developed methods for quantitative assessment of bacterial attachment and growth on metal surfaces. We have shown that few marine bacteria attach to metals coated with organic films. However, these bacteria quickly adapt to the new environment and grow rapidly. We are currently developing methods to assay organic acid production by these bacteria at crack and crevice corrosion sites. High pressure liquid chromatography is being used for these analyses.
