摘要

摘要: 厌氧消化是有机固废减污降碳协同资源化的关键共性技术，其互营产甲烷过程高度依赖以电子-质子传递为核心的能量代谢。直接种间电子传递（DIET）是种间能量传递的主流调控方向，但单一强化电子传递的调控模式易引起电子-质子传递解偶联，诱发胞外微环境酸化，制约其产甲烷增促效能。胞外质子耦合电子传递（PCET）可实现电子与质子协同转移，在维持胞外微环境酸碱稳态的同时，降低反应活化势垒，为强化厌氧互营产甲烷能量传递效率提供了新视角。然而，相关综述多围绕DIET展开，针对有机固废厌氧体系的胞外PCET尚缺乏对于作用机制、强化路径与表征方法的系统性论述。因此，系统阐释了厌氧系统中细胞膜与胞外聚合物介导胞外PCET的基本原理，厘清了原位理化调控与外源功能材料介导的PCET强化路径及其增促效应，归纳了同位素动力学、电化学与原位波谱联用的PCET多尺度表征技术体系；并探讨了当前研究的核心挑战与未来发展方向，以期为有机固废高效厌氧产甲烷的工程调控提供重要理论支撑与技术参考。

Abstract: Anaerobic digestion is a key common technology for achieving the reduction of pollution and carbon emission cooperating with the improvement of resource utilization. The syntrophic methanogenesis process is highly dependent on energy metabolism centered on electron-proton transfer. Direct interspecies electron transfer （DIET） represents the mainstream regulatory paradigm for interspecies energy transfer. However， regulatory modes focusing on sole electron transfer would induce electron-proton uncoupling， triggering extracellular microenvironment acidification and limiting the enhancement efficiency of methanogenesis. Extracellular proton-coupled electron transfer （PCET） conducts synchronous electron-proton transfer， which reduces the reaction activation barrier while maintaining the acid-base homeostasis of the extracellular microenvironment， offering a novel perspective for boosting the energy transfer efficiency during anaerobic syntrophic metabolism of methanogenesis. However， existing relevant reviews predominantly focus on DIET， whereas the mechanisms， enhancement pathways and characterization methods of extracellular PCET in the anaerobic systems of organic solid waste have not yet been systematically reviewed. Herein， we systematically elucidate the fundamental principles of extracellular PCET mediated by cell membranes and extracellular polymeric substances （EPS） in anaerobic systems. The enhancement pathways of PCET driven by in-situ physicochemical regulation and exogenous functional materials， as well as their corresponding methanogenic promotion effects， are clarified. By integrating isotope kinetics， electrochemistry， and in-situ spectroscopy， a multi-scale characterization framework for PCET is synthesized. Furthermore， current challenges and future research directions are discussed. This review provides a scientific basis for the engineering regulation of high-efficiency anaerobic methanogenesis from organic solid waste.
