Impact statement Methane‐producing microorganisms accelerate the corrosion of iron‐containing metals. Previous studies have inferred that some methanogens might directly accept electrons from Fe(0), but when this possibility was more intensively investigated, H 2 shown to be an intermediary electron carrier between Fe(0) and methanogens. Here, we report Methanosarcina acetivorans catalyzes direct metal‐to‐microbe transfer support methane production. Deletion gene for multiheme, outer‐surface c ‐type cytochrome MmcA eliminated production consistent with key role in other forms extracellular exchange. These findings, coupled previous demonstration cytochromes are also electrical contacts uptake by Geobacter Shewanella species, suggest presence multiheme on surfaces diagnostic interfering function a strategy mitigate corrosion.

Abstract Anaerobic microbial corrosion of iron‐containing metals causes extensive economic damage. Some microbes are capable direct metal‐to‐microbe electron transfer (electrobiocorrosion), but the prevalence electrobiocorrosion among diverse methanogens and acetogens is poorly understood because a lack tools for their genetic manipulation. Previous studies have suggested that respiration with 316L stainless steel as donor indicative electrobiocorrosion, because, unlike pure Fe 0 , does not abiotically generate H 2 an intermediary carrier. Here, we report all ( Methanosarcina vacuolata, Methanothrix soehngenii Methanobacterium strain IM1) Sporomusa ovata Clostridium ljungdahlii ) evaluated respired donor, only M. Mx.
