Mineralogy of a natural As-rich hydrous ferric oxide coprecipitate formed by mixing of hydrothermal fluid and seawater: Implications regarding surface complexation and color banding in ferrihydrite deposits

TL;DR: In this paper, the most As-rich natural hydr ous ferric oxide (HFO) material was characterized using powder X-ray diffraction (pXRD), transmission electron microscopy (TEM), XRF, light element analysis using gas chromatography (GC), visible-infrared (vis-IR) diffuse reflectivity, 57 Fe Mossbauer spectroscopy, and superconducting quantum interference device (SQUID) magnetometry.
Journal ArticleDOI
Biogeochemical factors influencing net mercury methylation in contaminated freshwater sediments from the St. Lawrence River in Cornwall, Ontario, Canada.

TL;DR: The inhibition of both methanogens and SRB was found to enhance the iron reduction rates but did not completely stop MMHg production, indicating that iron reduction may influence net methylation in the SLR sediments by decreasing demethylation rather than favouring methylation.
Journal ArticleDOI
Microbial sulfate reduction within sulfidic mine tailings: Formation of diagenetic Fe sulfides
TL;DR: In this paper, a study of the Kidd Creek mine tailings (Cu•Zn ore) reveals not only the existence of sulfate-reducing bacteria (SRB) in this sulfur-rich environment, but also the importance of their role in iron and sulfur cycling.
Journal ArticleDOI
Prevalence of anaerobic ammonium-oxidizing bacteria in contaminated groundwater.
Tara A. Moore,Yangping Xing,Brent Lazenby,Michael D. Lynch,Sherry L. Schiff,William D. Robertson,Robert Timlin,Sadia Lanza,M. Cathryn Ryan,Ramon Aravena,Danielle Fortin,Ian D. Clark,Josh D. Neufeld +12 more
TL;DR: It is shown that anammox performing organisms were abundant bacterial community members at three ammonium-contaminated groundwater sites, providing strong evidence for their important biogeochemical role in attenuating groundwater ammonium contamination.
Journal ArticleDOI
A rare earth element signature of bacteria in natural waters
TL;DR: Takahashi et al. as discussed by the authors showed that rare earth element (REE) distribution patterns between bacteria and water for five different bacterial strains (Bacillus subtilis, Escherichia coli, Alcaligenes faecalis, Shewanella putrefaciens, and Pseudomonas fluorescens) exhibit a steep increase in the heavy REE (HREE) part of the distribution pattern and a weak peak around the middle REE part.
