Microbial electrolysis cell (MEC) is a significantly sustainable bio-electrochemical system for
biological hydrogen production. MEC is also regarded as an environmentally friendly …

Electricity-driven microbial metabolism relies on the extracellular electron transfer (EET)
process between microbes and electrodes and provides promise for resource recovery from …

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 …

Sluggish extracellular electron transfer (EET) at the anode interface is the major obstacle to
achieving satisfactory power density in microbial fuel cells (MFCs). To boost the EET …

Large amounts of nitrogen fertilized to food production are lost via denitrification and
leaching. Dissimilatory nitrate reduction to ammonium (DNRA) is a bioprocess competing …

Reducing the electrode spacing in bioelectrochemical systems (BESs) are widely reported
to improve power output, which was mainly attributed to the decrease of ohmic resistance (R …

Limited access to the hydrophobic organic compounds by microorganisms impedes the
improvement of performance of bioreactor processing contaminant degradation. Here, we …

Microbes can cause or accelerate metal corrosion, leading to huge losses in corrosion
damages each year. Geobacter sulfurreducens is a representative electroactive bacterium in …

A low-cost cathode catalyst based on a NiMo alloy was examined here to replace noble
metals for the hydrogen production in microbial electrolysis cells (MECs). Two NiMo …

Groundwater, the main freshwater resource for humans, has been widely contaminated with
nitrate from fertilizers. Here, we report a new and chemical-free strategy to prevent nitrate …
