Cattle wastes as substrates for bioelectricity production via microbial fuel cells

  title={Cattle wastes as substrates for bioelectricity production via microbial fuel cells},
  author={Xianglei Zheng and N. Nirmalakhandan},
  journal={Biotechnology Letters},
A new 2 l scale microbial fuel cell (MFC) configuration was developed to generate bioelectricity from particulate substrates. Voltage and power densities generated in this MFC fed with sucrose, particulate cattle manure, and manure wash-water as the substrates were evaluated in batch mode, with and without external mediators. Voltages averaged 0.5 V in open circuit, and 0.4 V under a resistive load of 470 Ω. Power densities (67 to 215 mW/m2) were comparable to previous work that had used liquid… CONTINUE READING
