Performance of stacked microbial fuel cells with barley-shochu waste.

The treatment of barley-shochu waste combined with electricity generation was examined using stacked microbial fuel cells (SMFCs). The maximum chemical oxygen demand (COD) removal efficiency and maximum power density were achieved at 36.7 ± 1.

Unexpected genomic features of high current density-producing Geobacter sulfurreducens strain YM18.

Geobacter sulfurreducens produces high current densities and it has been used as a model organism for extracellular electron transfer studies. Nine G. sulfurreducens strains were isolated from biofilms formed on an anode poised at -0.

Proteolytic Maturation of the Outer Membrane -Type Cytochrome OmcZ by a Subtilisin-Like Serine Protease Is Essential for Optimal Current Production by Geobacter sulfurreducens.

An outer membrane -type cytochrome (OmcZ) in Geobacter sulfurreducens is essential for optimal current production in microbial fuel cells. OmcZ exists in two forms, small and large, designated OmcZ and OmcZ, respectively. However, it is still not known how these two structures are formed.

Electricity generation from sweet potato-shochu waste using microbial fuel cells.

Electricity generation and treatment of sweet potato-shochu waste, acidic and organic-rich slurry, was examined using cassette-electrode microbial fuel cells (CE-MFCs). Among CE-MFCs with raw (73 g-chemical oxygen demand chromium COD/L) and different concentration of diluted sweet potato-shochu waste (0.5, 1, 5, 10, and 20 g-COD/L) without pH control, the maximum power density (1.
