摘要	Magnetite is a mineral that is abundant in nature. In the coexistence of magnetite with syntrophic microorganisms, differential strategies for transferring electrons are mediated by magnetite, which may directly or indirectly influence the interspecific electron transfer (IET) process. This would be beneficial for the co-growth and metabolism of syntrophic microorganisms. Notably, this promotional effect will improve several environmental applications of renewable energy. In this study, several mechanisms regarding the magnetite-promoting IET process are systematically elaborated. The main mechanisms are: (1) magnetite possesses favorable redox properties that could serve as “environmental batteries”, (2) magnetite displays electrical conductivity equivalent to that of OmcS proteins, and (3) magnetite induces certain physiological responses in microorganisms by stimulating the secretion of extracellular polymeric substances and hopping the activities of enzymes related to electron transfer stimulated by magnetite. Environmental applications regarding the enhancement of IET with magnetite as a low-cost mediated material are currently increasing, especially the promotion of methanogenesis by fixing carbon dioxide, microbial dechlorination and denitrification, and anaerobic oxidation of methane. Finally, to address the shortcomings in the application of magnetite to promote IET, two improvement solutions are proposed. To improve the stability of magnetite, it could be filled in an inbuilt packed bed of an anaerobic-digestion reactor and modified to reduce the loss of iron. Moreover, more research should focus on employing multi-omics and isotope labeling technology and establishing a feasible system to elaborate the mechanism of the enhanced direct IET (DIET) process. Furthermore, the correlation between the ferromagnetic effect of magnetite and enhanced DIET should also be explored in depth.
