The first step is the failure of a major sealine transporting sour oil by a form of internal pitting apparently involving sulfate reducing bacteria(SRB). Then possible mechanisms were studied, where the theoretical roles of sulfate and thiosulfate were compared. Afterwards, the presence of thiosulfate was effectively identified in the produced water, and the growth of the local SRB was shown to be stronger on S{sub 2}O{sub 3}{sup {minus}} than on SO{sub 4}{sup {minus}}. Also non SRB fermentative strains, able to produce tremendous amount of H{sub 2}S and organic acids from thiosulfate and heavy nutrients (i.e. peptides) were collected. This might change the approach to microbially induced corrosion (MIC), in the oil and gas industry.
