Correlation of Power Generation With Time-Course Biofilm Architecture Using Klebsiella Variicola In Dual Chamber Microbial Fuel Cell

Correlation of Power Generation With Time-Course Biofilm Architecture Using Klebsiella Variicola In Dual Chamber Microbial Fuel Cell

In the present work, the wild type Klebsiella variicola was investigated in double chamber microbial fuel cell (MFC) using palm oil mill effluent as substrate which achieved high power density (4.5 W/m3) and coulombic efficiency (63%) while maintaining the moderate chemical oxygen demand (COD) remov...
