To successfully apply sediment microbial fuel cells (SMFCs) in remediating aquacultural sediments and water bodies on a large scale, SMFC systems with different electrode materials (carbon fiber brush, graphite felt, carbon cloth) structural forms were constructed, the advantages disadvantages of various electrodes compared terms electricity generation, pollutant removal, application cost. The ...

This work was conducted to examine the composition and electrochemical activity of the bacterial community inhabiting lake Furnas sediments (Azores). Fingerprinting analysis of the bacterial 16S rRNA gene fragment was done by denaturing gradient gel electrophoresis. The sequences retrieved from lake Furnas sediments were affiliated to Bacteroidetes/Chlorobi group, Chloroflexi, Alfa-, Delta-, an...

Microbial fuel cell and microbial electrolysis cell are two major types of microbial electrochemical cells. In the present study, we governed modeling of these systems by concentrating on the simulation of bioelectrochemical reactions in both biofilm and anolyte and considering the effect of pH on the microbial growth. The simulation of microbial fuel and electrolysis cells can be described by ...

Hexavalent chromium (Cr(VI)) is a well-known toxic heavy metal in industrial wastewater, but in situ and real time monitoring cannot be achieved by current methods used during industrial wastewater treatment processes. In this study, a Sediment Microbial Fuel Cell (SMFC) was used as a biosensor for in situ real-time monitoring of Cr(VI), which was the organic substrate is oxidized in the anode ...

BACKGROUND The microbial fuel cell represents a novel technology to simultaneously generate electric power and treat wastewater. Both pure organic matter and real wastewater can be used as fuel to generate electric power and the substrate type can influence the microbial community structure. In the present study, rice straw, an important feedstock source in the world, was used as fuel after pre...
