Utilization of Mangifera indica as Substrate to Bioremediate the Toxic Metals and Generate the Bioenergy through a Single-Chamber Microbial Fuel Cell

Table 2

Bioremediation trend of the toxic metals via single-chamber MFC fed with mango extract as the organic substrate.

Target pollutant	Organic substrate	Inoculation source in the anode chamber	Initial concentration of metal ions (ppm)	Operational time (days)	Bioremediation efficiency (%) of Pb (II)	Bioremediation efficiency (%) of Cd (II)	Bioremediation efficiency (%) of Cr (III)
Pb (II)	Mango extract	Synthetic wastewater	100	0	0.00	0.00	0.00
Cd (II)				10	30.10	29.00	34.90
Cr (III)				20	57.50	61.10	64.20
				30	75.00	74.11	80.50
