Abstract
A microbial fuel cell (MFC) has great potential for azo dyes decolorization and electricity generation by using filamentous fungi as biocatalysts. In this study, Aspergillus niger and Trichoderma harzianum were inoculated in anode chamber of double-chamber MFC to decolorize azo dye acid black 172 with Potassium Ferricyanide in the cathode chamber. During MFC operations, Acid black 172 oxidized and produced a maximum open-circuit voltage of 890 mV, and maximum current density of 163 mA/m² with an external resistance of 1000Ω. Also, variable parameters such as dye concentration, Co-substrate and dye as a sole carbon source were studied to improve microbial fuel cell performance.
Key findings
- Acid black 172 dye was successfully decolorized by Aspergillus niger and Trichoderma harzianum in the MFC.
- The MFC generated a maximum open-circuit voltage of 890 mV and a maximum current density of 163 mA/m².
- Variable parameters such as dye concentration, Co-substrate, and dye as a sole carbon source were studied to improve MFC performance.
