ABSTRACT
Aim of the study:
This study aims to develop the novel model of multi-electrode MFC with the termite-associated yeast G. reessii for MG decelorization and electricity generation.
Material and methods:
The termite-associated yeast G. reessii was inoculated into modified midia with 150 mg/L MG. The laccase activity and MG removal was studied. Then, the G. reessii was immobilized on anode surface. The electrical properties and color removal were tested.
Results and conclusions:
The results showed it successfully removed the MG with 98.15±0.92% within 1 day of operation. Moreover, the OCV, CD and PD of 550.00±10.00%, 3.90±0.10 A/m3 and 1.52±0.08 W/m3 were achieved. Therefore, the system could have the potential for treatment of high concentration MG contaminated wastewater and produce a bio-electric energy.
