Abstract

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.

Key findings

  • The microbial fuel cell with consortium KJW40 achieved current densities of 4,816.67 mA/m³
  • The power densities reached 2,320.08 mW/m³
  • The Rhodamine B removal rate was 80.56%
