Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Direct interspecies electron transfer (DIET) has been demonstrated to be an efficient type of
mutualism in methanogenesis. However, few studies have reported its presence in mixed …

The inefficiency of interspecies electron transfer between syntrophic bacteria and
methanogens typically restricts the reaction rates and methanogenesis efficiency of …

Anaerobic digestion was one of the first bioenergy strategies developed, yet the interactions
of the microbial community that is responsible for the production of methane are still poorly …

Electrochemically active bacteria can transport their metabolically generated electrons to
anodes, or accept electrons from cathodes to synthesize high‐value chemicals and fuels, via …

Background Anaerobic digestion (AD) is a globally important technology for effective waste
and wastewater management. In AD, microorganisms interact in a complex food web for the …

Iron compounds are abundantly present in both natural and engineered anaerobic
environments where various biological processes including methanogenesis take place …

Methanothrix is widely distributed in natural and artificial anoxic environments and plays a
major role in global methane emissions. It is one of only two genera that can form methane …

Anaerobic digestion of municipal and other organic waste is a microbial process for
conversion of complex organic substances to biogas (a renewable energy source) …
