| 释义 |
This process is the opposite to that employed in a microbial fuel cell, in which microorganisms transfer electrons from the oxidation of compounds to an anode to generate an electric current. Comparison to microbial electrolysis cellsMicrobial electrosynthesis is related to microbial electrolysis cells (MEC). Both use the interactions of microorganisms with a cathode to reduce chemical compounds, but differ in the source of power for this process. In microbial electrosynthesis electrons are supplied solely by the external electrical power source. In MECs, an electrical power source is used to augment the electrical potential produced by the microorganisms consuming a source of chemical energy such as acetic acid. The combined potential provided by the power source and the microorganisms is then sufficient to for example reduce hydrogen ions to molecular hydrogen.[2] ApplicationsMicrobial electrosynthesis may be used to produce fuel from carbon dioxide using electrical energy generated by either traditional power stations or renewable electricity generation. It may also be used to produce speciality chemicals such as drug precursors through microbially assisted electrocatalysis.[3] Microbial electrosynthesis can also be used to "power" plants. Plants can then be grown without sunlight.[4][5][6] See also
