Abstract Scope Microbiologically influenced corrosion (MIC) is a long-standing but unpredictable phenomenon, that when left unchecked has severe consequences. Several microbial species have been identified and characterized for their corrosive properties, such as sulfate-reducing bacteria (SRB) and methanogenic archaea (MA). In contrary to SRB, the metabolic product of MA, methane, is unreactive to the metal surface, which raises more questions regarding their corrosion mechanisms. We used a novel and integrative approach to gain insights into the corrosive properties of MA. Macroscopically, we studied the corrosion mechanisms of MA by analyzing the corrosion products formed under static and flow-based systems using SEM-FIB-EDX, TOF-SIMS and AFM. At a microscopic level, we studied the elemental fingerprint of MA post-metal exposure using inductively-coupled plasma mass spectrometry (ICP-MS). By combining several techniques, we hope to provide an overview on the mechanistic potential of corrosive MA and their possible roles in the global metal-cycle.
