The coexistence of different pollutants in groundwater is a common threat. Sustainable and resilient technologies are required for their treatment. present study aims to evaluate microbial electrochemical (METs) treating contaminated with nitrate (NO3?) while containing arsenic (in form arsenite (As(III)) as co-contaminant. treatment was based on the combination reduction dinitrogen gas oxidati...

The treatment of wastewater is an expensive and energy-extensive practice that not only ensures the power generation requirements to sustain current energy demands increasing human population but also aids in subsequent removal enormous quantities need be treated within environment. Thus, renewable source-based one recently developing techniques overcome environmental contamination issues. In t...

The non-covalent modification of carbon nanotube electrodes with pyrene derivatives is a versatile approach to enhance the electrical wiring enzymes for biosensors and biofuel cells. We report here comparative study five adsorbed at multi-walled shed light on their ability promote direct electron transfer horseradish peroxidase (HRP) H 2 O reduction. In all cases, pyrene-modified enhanced catal...

Bioelectrochemical systems (BESs) have been shown to be useful in removing individual metals from solutions, but effective treatment of electroplating and mining wastewaters requires simultaneous removal of several metals in a single system. To develop multiple-reactor BESs for metals removal, biocathodes were first individually acclimated to three different metals using microbial fuel cells wi...

Green hydrogen from photocatalytic water-splitting and lignocellulosic reforming is a significant proposition for renewable energy storage in global net-zero policies strategies. Although have been investigated, their integration novel. Furthermore, biosynthesis can store the evolved fix atmospheric carbon dioxide biocathode chamber. The chamber coupled to combined lignocellulose oxidation an a...

Sediments play an important role in determining the quality of lakes, rivers and oceans as they can act as either a source or sink for pollutants. Once the input pollution is controlled, sediments as a secondary source of pollution can release the accumulated pollutants to overlying water.1 The organic matter content of sediments can also affect the structure of macroinvertebrate assemblages.2 ...

In its simplest form, bioelectrochemical systems (BESs) consist of an anode, a cathode, and a microbial catalyst (Rabaey and Rozendal, 2010). One of the attractive features of bioelectrochemical technology is that, BESs can be developed to implement anodic-based or cathodic-based bioprocesses or both at the same time. For example, pollutants can be degraded by a specialized microbial catalyst a...
