Description:
<jats:p>As AMD moves through the environment, it impacts aquatic ecosystems, but at the same time, these ecosystems can naturally attenuate contaminated waters via acid neutralization and catalyzing metal precipitation. This is the case in the former Ronneburg uranium-mining district, where AMD impacts creek sediments. We isolated and characterized two iron-oxidizing<jats:italic>Thiomonas</jats:italic>species that are mildly acidophilic to neutrophilic and that have two genetic pathways for iron oxidation. These<jats:italic>Thiomonas</jats:italic>species are well positioned to naturally attenuate AMD as it discharges across the landscape.</jats:p>
