Journal ArticleDOI
Reduction kinetics of Fe(III), Co(III), U(VI), Cr(VI), and Tc(VII) in cultures of dissimilatory metal‐reducing bacteria
TL;DR: The more precise rate coefficients of the first-order model provided a better means than the Monod parameters, to quantitatively compare the reduction rates between metals, electron donors, and DMRB species.
Journal ArticleDOI
Geochemical Implications of Gas Leakage Associated with Geologic CO2 Storage - A Qualitative Review
Omar R. Harvey,Omar R. Harvey,Nikolla P. Qafoku,Kirk J. Cantrell,Giehyeon Lee,James E. Amonette,Christopher F. Brown +6 more
TL;DR: Current knowledge gaps on how elevated CO(2) levels could influence geochemical processes in potable aquifers and the vadose zone are discussed and addressing them is pivotal in advancing current scientific knowledge on how leakage from GCS may impact the environment.
Journal ArticleDOI
Microbial Reduction of Fe(III) and Sorption/Precipitation of Fe(II) on Shewanella putrefaciens Strain CN32
TL;DR: A modified Monod model incorporating a lag phase, Fe(II) adsorption, and aqueous complexation reactions was able to describe the experimental results of microbial Fe(III)aq reduction and cell growth when cells were pretreated with Fe( II)aq.
Journal ArticleDOI
Key factors for determining groundwater impacts due to leakage from geologic carbon sequestration reservoirs
Susan A. Carroll,Elizabeth H. Keating,Kayyum Mansoor,Zhenxue Dai,Yunwei Sun,Whitney Trainor-Guitton,Christopher F. Brown,Diana H. Bacon +7 more
TL;DR: In this paper, the authors describe potential impacts to groundwater quality due to CO2 and brine leakage, discuss an approach to calculate thresholds under which no impact to groundwater occurs, describe the time scale for impact on groundwater, and discuss the probability of detecting a groundwater plume should leakage occur.
Journal ArticleDOI
Biotransformation of Ni-Substituted Hydrous Ferric Oxide by an Fe(III)-Reducing Bacterium
James K. Fredrickson,John M. Zachara,Ravi K. Kukkadapu,Yuri A. Gorby,Steven C. Smith,Christopher F. Brown +5 more
TL;DR: In this article, a reductive biotransformation of a Ni2+-substituted (5 mol %) hydrous ferric oxide (NiHFO) by Shewanella putrefaciens, strain CN32, was investigated under anoxic conditions at circumneutral pH.
