摘要:蚯蚓肠道是接近于厌氧状态的微环境，肠道中富含大量的厌氧或兼性厌氧菌，它们对蚯蚓自身机能的稳定和土壤养分元素循环及污染物降解转化等均具有重要作用。因此，探明蚯蚓肠道细菌群落结构组成和功能多样性，挖掘蚯蚓肠道细菌环境功能潜力，对于促进农业生产及污染土壤可持续修复治理具有重要的理论和现实意义。本文主要从蚯蚓肠道细菌群落的组成、肠道菌群对土壤中污染物的解毒机制、肠道菌群对土壤中养分元素循环转化的影响及肠道菌群功能基因多样性的角度，对近年来蚯蚓肠道细菌生态功能及毒理学研究进展进行了综述，并对现有研究不足进行了总结，提出了未来研究的发展方向。

Abstract:The earthworm intestine is an anaerobic microzone, mainly colonized by (facultative) bacteria. It plays an important role in maintaining the earthworm metabolism, nutrient cycling, and pollutant degradation in soil. To improve the agricultural production and soil quality, it is of great significance to explore the bacterial composition and diversity in the earthworm gut, and the potential environmental functioning of the earthworm intestinal bacteria. Here we review the bacterial composition in the earthworm gut, their detoxification mechanism of the soil pollutants, and the close involvement in the soil nutrient transformation. This review provides important information concerning the status quo and the future prospective of the earthworm intestinal bacteria in the ecological functioning and the toxicology research.
