Biofilm of Desulfovibrio Desulfuricans

Biofilm of sulfate-reducing, anaerobic bacteria Desulfovibrio desulfuricans grown on a hematite surface. D. desulfuricans is being studied for its ability to reduce toxic metals and radionuclides such as chromium and uranium in soils and groundwater. The photo is a color-enhanced digital micrograph of a black and white scanning electron microscope (SEM) image. Biofilms are complex communities of microorganisms that adhere to surfaces such as teeth or river rocks. They are comprised of highly structured polysaccharide matrix-enclosed communities separated by a network of open water channels.
