Effects on Solution Chemistry within Regions of the Biofilm

Microorganisms and Effects on Solution Chemistry within Regions of the Biofilm (Ref72, 73) 

The microorganisms that have been commonly associated with MIC are  

For each, the generally required environmental condition (aerobic or anaerobic), the primary metabolic processes related to MIC, and the resultant chemical species that can increase corrosion rates are summarized in Table 7.4. These characteristics are discussed in the following paragraphs. 

Sulfiir/sulfide-oxidizing bacteria are aerobic and oxidize sulfide to el-emental sulfur (S2 — S + 2e), sulfide to sulfate
