Corrosion is frequently accelerated in the presence of bacterial biofilms on metal surfaces. Microbially produced exopolymers have been implicated in these corrosion processes. However, the mechanisms are not fully understood. We have examined the binding of four different metals to microbially produced exopolymer and have established considerable differences in maximum binding abilities and stability constants. These results have important implications for corrosion under biofilms, and are discussed in terms of specific ion concentration cells and galvanic coupling.
