Abstract:Electroactive microbes can conduct extracellular electron
transfer
and have the potential to be applied as a bioresource to regulate
soil geochemical properties and microbial communities. In this study,
we incubated Fe-limited and Fe-enriched farmland soil together with
electroactive microbes for 30 days; both soils were incubated with
electroactive microbes and a common iron mineral, ferrihydrite. Our
results indicated that the exogenous electroactive microbes decreased
soil pH, total organic carbon (TOC), an… 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.
