Varied salt concentrations (0.5M, 1M, 2M, and 3M) of salt bridge in MFC have been analyzed with different fac...

Converting Low-grade Biomass to Produce Energy Using Bio-fuel Cells

Aerobic and anaerobic respiration of microorganisms involves redox reactions that provide energy for cell growth or maintenance. The energy comes from breaking up chemical bonds during the oxidation of organic carbons by the microorganisms. The electrons released from the oxidation are taken up by the reduction of an oxidant such oxygen, sulfate, nitrate, etc. If the oxidation and reduction rea...
