Nitrogen gas (N2) fixation in the anode-respiring bacterium Geobacter sulfurreducens
occurs through complex, multistep processes. Optimizing ammonium (NH4+) production …

The present nitrogen fixation industry is usually energy-intensive and environmentally
detrimental. Therefore, it is appealing to find alternatives. Here, we achieved both a …

Diazotrophs can produce bioavailable nitrogen from inert N2 gas by bioelectrochemical
nitrogen fixation (e-BNF), which is emerging as an energy-saving and highly selective …

Ammonia (NH3) is an important industrial chemical that is produced using the energy-and
carbon-intensive Haber-Bosch process. Recovering NH3 from microorganisms that fix …

Comprehensive metabolomic analysis of anode-respiring Geobacter sulfurreducens cells
revealed that intracellular levels of metabolites related to the tricarboxylic acid (TCA) cycle …

Previous studies have identified that Geobacter sulfurreducens has three different electron
transfer pathways for respiration, and it switches between these pathways to adapt to the …

BESs are a novel treatment technology to remove or recover nitrogen from wastewater
coupling to electricity generation in a microbial fuel cell (MFC) or hydrogen production in a …

Geobacter species often play an important role in bioremediation of environments
contaminated with metals or organics and show promise for harvesting electricity from waste …

Anode-respiring bacteria (ARB) generate electric current in microbial electrochemical cells
(MXCs) by channeling electrons from the oxidation of organic substrates to an electrode …

Biological nitrogen fixation is a key step in the reduction of N 2 to available nitrogen in the
global nitrogen cycle. Pseudomonas stutzeri A1501 is an electroactive diazotroph and …
