Abstract:Polarity inversion from the bioanode to the biocathode
enables
a rapid formation of efficient biofilms for microbial electrochemical
reduction. Though this approach has been widely adopted for various
applications, the mechanism behind the enhanced extracellular electron
transfer (EET) during the polarity inversion process remains unclear.
Therefore, in this study, the succession pattern and electron transfer
mechanism of the inverted denitrifying biocathode were investigated
by continuously monitoring the ele… 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.
