A New Report of Rhodamine B Contaminated Wastewater Decolorization and Electricity Generation by Laccase Based Microbial Fuel Cell

Rhodamine B (RB) is a basic color for natural plant textile dyeing. This study aims to use the laccase and manganese peroxidase-producing consortium to degrade the RB and generate electrical energy in a novel model microbial fuel cell (MFC). The results revealed that the MFC with consortium KJW40 had current densities and power densities of 4,816.6728.87 mA/m3, and 2,320.0827.86 mW/m3, respectively. The RB removal rate was 80.560.13 % was reached. This work gained new knowledge about using a bacterial consortium producing laccase and manganese peroxidase to treat contaminated RB and generate electrical power.
