Item Bacterial Biofilms in Relation to Internal Corrosion Monitoring and Biocide Strategies(1988) Costerton, J. William; Geesey, Gill G.; Jones, P. A.This paper is a review of leading research in the field of bacterial corrosion monitoring with specific emphasis on systems that transport liquids rather than gases. However, the principles of bacterial corrosion presented below are universal and independent of whatever media is transported through the pipeline. It has now been established that the primary mechanism of bacterial corrosion of metal surfaces involves the creation, within an adherent biofilm, of local physiochemical ''corrosion cells''. The practical consequence of this perception is that we now know that bacteria must be in sustained contact with a metal surface, in well-organized microbial communities before the corrosion process is initiated. Decades of research in Aquatic Microbiology have shown that numbers and types of planktonic (floating) bacteria bear little relationship to the numbers and types of sessile (adherent) bacteria in biofilms in the same system, and that planktonic bacteria are much more susceptible to antibacterial agents than are their sessile counterparts.Item An observation of microbial cell accumulation in a finned tube(1983-12) Turakhia, Mukesh Harilal; Characklis, William G.Biofouling in heat exchange equipment results in significant energy loss by increasing heat transfer resistance and fluid frictional resistance. This paper compares the deposition and distribution of attached microbial cells on a smooth tube and a tube with inner fins after 100 hours exposure. Preliminary results suggest a significantly different distribution of attached microbial cells on the finned tube.
