Microbiologically induced corrosion monitoring using open-circuit potential (OCP) measurements

This study investigates how sulfate-reducing bacteria (SRB) influence the process of microbiologically induced corrosion (MIC) of carbon steel by measuring corrosion potential using open-circuit potential (OCP) measurements. MIC is mainly influenced by D. Vulgaris, formerly known as D. Desulfuricans...
