Abstract
ℱSulfate-reducing bacteria （SRB） are a group of diverse anaerobic microorganisms omnipresently in natural habitats and engineered environments, they use sulfur compounds as the electron acceptor for energy metabolism. SRB corrosion is one of major cause for corrosion damages and facility failures, making it an important research topic. Due to the complexity of microbiological activities and that there is a lack of deep understanding of the interaction between biofilms and metal surfaces in the present, therefore, it is still hard to predict and interpret the occurrence and the relevant mechanism of the SRB corrosion. In this review, the ecological characteristics and anaerobic respiration of SRB are introduced, focusing on the SRB corrosion mechanism, including cathodic depolarization, metabolite corrosion, concentration battery action, and extracellular electron transfer theories. Finally, the methods and tools of MIC research are briefly introduced.
