outer electron

Therefore, it is assumed that the ability of electrogenic microorganisms to produce electricity is related to their capacity to transfer electrons onto natural extracellular electron acceptors, such as Fe(Ⅲ) oxides.

自然界中并无微生物产电的直接进化压力,而MFC电极与自然界中Fe(III)氧化物同为难溶性胞外电子受体,研究表明,铁还原菌对二者的还原有相似机制。
