100 Electrochemically Enabled Sustainability
Many studies have revealed that the exoelectrogenic, sulphur-oxidising
and sulphate-reducing bacteria in MFCs can harvest electricity during sul-
phide oxidation [117,118]. By employing a pure culture (Pseudomonas sp. C27)
to start up a dual-chamber MFC, Lee etal. [117] obtained a maximum power
density of 29.3 mW m
−2
using sulphide as the sole electron donor. Based on
the high diversity and activity of anodic microorganisms, MFCs are capa-
ble of using a wide range of refractory organic pollutants as the substrate
to produce electricity. Such examples include antibiotic compounds [119],
pentachlorophenol [120], various dyes [121], pyridine [122], pharmaceutical
wastes [123] and so forth. MFCs perform ...
