Abstract

Purpose of Review

Organic waste management is crucial for global sustainable development. Dark fermentation is an effective method for reutilizing organic wastes while generating hydrogen. However, some substances in organic wastes may interfere with hydrogen-producing microorganisms, thereby reducing hydrogen production. Among these substances, emerging contaminants are receiving increasing attention due to their potential risks, environmental persistence, diverse sources, and ecotoxicity, posing a potential threat to the stability and efficiency of dark fermentation. Therefore, this comprehensive review aims to discuss the impacts of emerging contaminants on hydrogen production in dark fermentation, and corresponding mechanisms and control strategies.

Recent Findings

The sources of emerging contaminants in organic wastes are summarized. The effects of emerging contaminants on dark fermentative hydrogen production are systematically and critically summarized. Most of emerging contaminants inhibit hydrogen production. The mechanisms of emerging contaminants affecting hydrogen production in dark fermentation are discussed from perspectives of microbial physiological response, community structure, and metabolic pathways. Additionally, control strategies to alleviate the inhibitory effects of emerging contaminants on dark fermentation are summarized.

Summary

This review contributes to understanding how these emerging contaminants affect microbial systems, which is essential to safeguard the metabolic efficiency and operational stability. Future research directions are proposed for dark fermentation of organic wastes containing emerging contaminants.

暗发酵产氢新污染物的来源、影响、机制及控制策略综述

有机废物管理对全球可持续发展至关重要。暗发酵是一种有效的有机废弃物资源化和产氢的方法。然而，有机废物中的某些物质可能干扰产氢微生物，从而减少产氢。在这些物质中，新兴污染物因其潜在的风险、环境持久性、来源的多样性和生态毒性而受到越来越多的关注，对暗发酵的稳定性和效率构成潜在威胁。因此，本文就新出现的污染物对暗发酵产氢的影响、机制和控制策略进行综述。综述了有机废物中新出现的污染物的来源。对新出现的污染物对暗发酵制氢的影响进行了系统和批判性的总结。大多数新出现的污染物抑制氢的产生。从微生物生理反应、群落结构和代谢途径等方面讨论了暗发酵中新出现的污染物影响产氢的机制。此外，还总结了缓解新出现污染物对暗发酵抑制作用的控制策略。本文综述有助于了解这些新出现的污染物如何影响微生物系统，这对保障代谢效率和运行稳定性至关重要。提出了含新发污染物有机废弃物暗发酵的研究方向。
