Resources Recovery From Wastewater Based on Extracellular Electron Transfer

Abstract Extracellular electron transfer of microorganisms is attracting worldwide attention, driven by the promise of resource recovery from various wastes and wastewaters. This method is an expanding range of cross-disciplines, although a better understanding of all of the components is required to improve its behavior. In this chapter, we discuss the mechanisms of microbial electron transfer (ie, direct electron transfer and indirect electron transfer) and the capabilities of resource recovery from wastewater and other sorts of waste. Different techniques are elucidated to analyze the limiting performances of each component and optimize the operation processes of resource recovery.
