This study investigates the mechanisms by which methanogenic archaea (MA) influence the corrosion of magnesium (Mg) alloys, focusing on both direct and indirect electron transfer from the metal. A key question is whether pores in the passivation layer serve as functional channels for electron transfer between Mg and MA. Additionally, the role of sulfate-reducing bacteria (SRB) in accelerating Mg alloy corrosion is examined, along with the impact of MA-SRB interactions on corrosion dynamics. Finally, the study explores potential bifunctional inhibitors that could simultaneously protect the Mg surface and inhibit microbial growth, offering a novel approach to mitigating microbiologically influenced corrosion (MIC).
