The reversibility of the electron transfer between electrodes and cells provides a promising way to produce sustainable transportation and chemical production needs. Typically, microbial electrosynthesis (MES) is conducted in a system, which consists of an anode, a cathode and a membrane separating the two. Microorganisms capture electrons derived from the anode to reduce carbon dioxide to multicarbon organic compounds. In this regard, MES is considered as a promising strategy for solving global environmental problem by reducing the greenhouse gas as well as energy depletion by converting electrical energy into forms that can be readily stored and distributed. However, such MES systems are limited by the difficult electrical wiring of microbes to the electrode. Here, we show the efficient wiring of microbes in a carbon nanofiber (CNF) matrix, which has extremely high surface area, excellent electrical conductivity and chemical inertness. The formation of carbon nanofiber-microbe composite biofilm facilitates the electron-transfer between electrode and microbes and accordingly improves the overall performance of MES. The effects of CNF on the MES systems of several acetogens were investigated.
