The harvested energy using MFCs by enriching saline-alkali tolerant microorganisms from biogas slurry.

ABSTRACT: Exoelectrogenic biofilms is crucial for the energy generation and wastewater treatment by bioelectrochemical systems. In this study, two kinds of saline-alkali tolerant mixed exoelectrogenic cultures were enriched from biogas slurry. These mixed exoelectrogens produced current densities of 1,034 ± 30 and 974 ± 53 μA·cm^-2, which were 1.68 and 1.58 times higher than G. sulfurreducens PCA at pH 9.0, respectively. Under alkaline conditions with the addition of 1.5% NaCl, the maximum current densities for BS-N₂ (546.66 ± 139.20 μA·cm^-2) and BS-O₂ (583 ± 22.91 μA·cm^-2) were about 2.45 and 2.61 times higher than G. sulfurreducens PCA, respectively. The BS-O₂ exhibited a high power density of 1,109 ± 115 mW·m^-2
