Effects Of Process Parameters On Geobacter Sulfurreducens And Bacillus Subtilis From Dewatered Sludge For Electricity Generation In Membrane – Less Microbial Fuel Cell
The membrane-less microbial fuel cell (ML-MFC) is a cutting-edge renewable energy technology that might help to solve the world's energy dilemma. Electrogenic bacteria (EB) which are Geobacter sulfurreducens (GS) and Bacillus subtilis (BS) served as a biocatalyst in the ML-MFC, allowing it to c...
