The discovery of the function of humin (HM), an insoluble fraction of humic substances (HSs), as an extracellular electron mediator (EEM) in 2012 has provided insight into the role of HM in nature and its potential for in situ bioremediation of pollutants. The EEM function is thought to enable the energy network of various microorganisms using HM. Recently, a number of studies on the application of HM as EEM in anaerobic microbial cultures have been conducted. Even so, there is a need for developing a holistic view of HM EEM function. In this paper, we summarize all the available information on the properties of HM EEM function, its applications, possible redox-active structures, and the interaction between HM and microbial cells. We also suggest scopes for future HM research.
2012 年，腐殖质（HS）不溶性部分腐黑物（HM）作为细胞外电子介体（EEM）的功能被发现，这使人们对 HM 在自然界中的作用及其对污染物原位生物修复的潜力有了更深入的了解。人们认为，EEM 功能使各种微生物能够利用 HM 形成能量网络。最近，已经有许多关于将 HM 用作厌氧微生物培养物中的 EEM 的应用研究。即便如此，仍需要对 HM EEM 功能有一个全面的认识。在本文中，我们总结了关于 HM EEM 功能的所有现有信息，包括其应用、可能的氧化还原活性结构以及 HM 与微生物细胞之间的相互作用。我们还为未来的 HM 研究提出了一些建议。
