摘要	The respective roles of IOB and SRB in mixed microbial corrosion of carbon steel pipelines were investigated by surface analysis and electrochemical measurements. The results indicate that in initial corrosion stage the extracellular polymeric substances (EPS) of SRBs can hinder the adhesion of IOB and inhibit corrosion nodulation formation. As SRB:IOB increases from 0:22500 cells/mL to 22500:22500 cells/mL, the size and number of corrosion nodulations decrease by two orders of magnitude. In latter corrosion stage, the SRBs become the dominant microbes, accelerating the propagation of corrosion nodulations in mixed microbial system due to low dissolved oxygen (DO).
