The study of riboflavin-mediated indirect electron transfer process in corrosion of EH40 steel induced by Methanococcus maripaludis

The riboflavin-mediated indirect electron transfer process during EH40 steel corrosion was investigated in Methanococcus maripaludis medium. The results showed that exogenous riboflavin participates in the process of EH40 steel corrosion induced by M. maripaludis. The presence of riboflavin promotes pitting corrosion of EH40 steel in M. maripaludis medium, but this trend is mitigated by increasing concentrations of riboflavin. Both anodic and cathodic processes of EH40 steel corrosion are enhanced in M. maripaludis media with riboflavin. The speed of transportation of electron on EH40 steel surface through riboflavin reduction is faster than proton reduction.

Automated summary

In this study, the riboflavin-mediated indirect electron transfer process during EH40 steel corrosion in Methanococcus maripaludis medium was investigated. The results showed that the presence of exogenous riboflavin promotes pitting corrosion of EH40 steel in the medium, but this trend is mitigated by increasing riboflavin concentrations. Additionally, both anodic and cathodic processes of EH40 steel corrosion are enhanced in the presence of riboflavin.
