Abstract
Around 20 % of industrial water pollution is contributed by the textile dyeing and
finishing of fabric. The dyes used in textiles pose environmental hazards and adversely
affect human health. Thus, researchers are on a stride to find out an energy-efficient
and eco-friendly process to remediate dyes. One such process is Microbial Fuel Cells
(MFC) that has gained immense popularity in the past decade for their ability to
produce electricity from wastewater. In this review, we focus on the remediation
of Azo dye and the simultaneous generation of bioelectricity using MFC. We have
discussed the mechanism of using azo dye at the anode as a co-substrate and at the
cathode as an electron acceptor.
We have also discussed the factors affecting the performance of an MFC system, such
as substrate and dye concentration. Finally, we have provided a comprehensive overview
of the current research trends and potential advancements of MFC technology. MFC
is a challenging yet promising technology and its performance can be improved through
further research.
