十年间，细胞外电子转移已经从一种环境现象发展成为工业过程的驱动力。一方面，电子向阳极的转移导致产生电能或化学物质，如氢、苛性钠和过氧化氢。另一方面，来自阴极的电子转移使生物修复和生物生产成为可能。虽然细胞外电子转移的微生物学正在被越来越多地理解，但将这些过程应用到应用中需要考虑到操作和技术上的一些问题。在本文中，我们研究了与电力驱动生物生产相关的关键应用方面，包括生物膜的开发、反应器和电极的设计、底物通量、表面化学、流体动力学和电化学，以及最终产物的去除/毒性。这些方面中的每一个都将对充分利用细胞外电子转移这一有趣的生理壮举至关重要。
Extracellular electron transfer has, in one decade, emerged from an environmental phenomenon to an industrial process driver. On the one hand, electron transfer towards anodes leads to production of power or chemicals such as hydrogen, caustic soda and hydrogen peroxide. On the other hand, electron transfer from cathodes enables bioremediation and bioproduction. Although the microbiology of extracellular electron transfer is increasingly being understood, bringing the processes to application requires a number of considerations that are both operational and technical. In the present paper, we investigate the key applied aspects related to electricity-driven bioproduction, including biofilm development, reactor and electrode design, substrate fluxes, surface chemistry, hydrodynamics and electrochemistry, and finally end-product removal/toxicity. Each of these aspects will be critical for the full exploitation of the intriguing physiological feat that extracellular electron transfer is today.
