Abstract:Microbially
mediated sulfate reduction is a promising cost-effective
and sustainable process utilized in permeable reactive barriers (PRB)
and constructed wetlands to treat mine wastewater. Laboratory batch
experiments were performed to evaluate nickel (Ni) isotope fractionation
associated with precipitation of Ni-sulfides in the presence of the
sulfate-reducing bacterium (SRB) Desulfovibrio desulfuricans
T (DSM-642). Precipitates were collected anaerobically
and characterized by synchrotron powder X-ray diffr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
