Abstract

Shewanella spp. are frequently found on corroded metal structures. Their role in microbial influenced corrosion has been attributed mainly to their Fe(III)-reducing properties and, therefore, has been studied with the addition of an electron donor (lactate). Shewanella spp., however, can also use solid electron donors, such as cathodes and potentially Fe(0). In this work, we show that the electron acceptor fumarate supported the use of Fe(0) as the electron donor by Shewanella strain 4t3-1-2LB, which caused a (7.0 ± 0.6)-fold increase of the corrosion rate. The corrosion-enhancing mechanism likely involved cell surface-associated components in direct contact with the Fe(0) surface or maintenance of low hydrogen levels by attached cells, thereby favoring chemical hydrogen formation by Fe(0). This work sheds new light on the role of Shewanella spp. in biocorrosion, while the insights into the corrosion-enhancing mechanism contribute to the understanding of extracellular electron uptake processes.

  • Shewanella spp. can donate electrons in several different ways, making them useful for getting rid of contaminants such as nitrate, TMAO, azo dyes, and oxidized metals, and they thrive in high salinity and heavy metal environments.

    “Shewanella spp.can donate electrons in several different ways, which makes them useful for getting rid of contaminants such as nitrate, TMAO, azo dyes, and oxidized metals.They thrive in high salinity and heavy metal environments [282].”

    From Harnessing bacterial consortia for effective bioremediation: targeted removal of heavy metals, hydrocarbons, and persistent pollutants (2025) · cites this paper as [282]

    The paper’s Abstract describes Shewanella using solid electron donors and acceptors, and its Ecological relevance and technological implications section names nitrate and Fe(III) among its electron acceptors (page numbers unavailable). It does not establish contaminant removal involving TMAO or azo dyes, or that Shewanella thrive in high-salinity and heavy-metal environments; its focus is iron corrosion. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
