Main Components

The microbial fuel cell (MFC) constructed by a modified Continuous Stirred Tank Reactor (CSTR) which was used as acidification-phase of two-phase anaerobic digestion system. The experiment was operated as batch mode at mesophilic condition (35°C) to evaluate continue voltage output using cattle dung as substrate in hydrolysis-acidification process. The results illustrated that electricity generation increased noticeably to 300mV after 3 days operation, reached 430mV after 20 days and stabilized electricity generation from 420mV to 470mV in the following 70 days. The pH decreased from 7.15 to 6.65 after 15 days operation and maintained stability from 6.4 to 6.8. The main components of VFA in anode chamber were acetic, propionic and butiric acids. The dominating VFA was acetic acid that predominated untile day 50 and the maximum propionic acid concentration was 15% of total VFA.

Biocatalyzed Electrolysis

Biocatalyzed electrolysis is a microbial fuel cell based technology for the generation of hydrogen gas and other reduced products out of electron donors. Examples of electron donors are acetate and wastewater. An external power supply can support the process and therefore circumvent thermodynamical constraints that normally render the generation of compounds such as hydrogen unlikely. We have investigated the possibility of biocatalyzed electrolysis for the generation of methane. The cathodically produced hydrogen could be converted into methane at a ratio of 0.41 mole methane mole−1 acetate, at temperatures of 22±2°C. The anodic oxidation of acetate was not hampered by ammonium concentrations up to 5 g N L−1.An overview is given of potential applications for biocatalyzed electrolysis.
