摘要	Sulfate-reducing bacteria (SRB)-induced corrosion of 2205 duplex stainless steel (DSS) was investigated via novel high-resolution characterization. After 28 days of immersion, the corrosion rate of coupons in the SRB-inoculated medium was 10 times higher than that of coupons in the sterile medium. Corrosion products were absent from the top-part of the biofilm where acidic - COOH was present, which indicated corrosion was not caused by metabolites. SRB clung to the matrix and mutually dissolved, which may favor electron transmission. Extracellular electron transfer (EET), breakage of the passive film and inhibition of passive film repair contributed to SRB-induced corrosion in this study.
