报告题目：蚯蚓对洛克沙胂的生物转化及其作用下的土壤砷释放风险：蚯蚓肠道细菌的作用

报告摘要：

蚯蚓被誉为土壤生态工程师，其肠道微生物在生态服务中起着关键作用。虽然蚯蚓的活动增加了土壤的透气性，但是蚯蚓肠道形成了一个移动的厌氧区域，使得蚯蚓肠道和土壤中的微生物群落间有显著差异。报告人主要介绍洛克沙胂污染胁迫下蚯蚓对土壤砷释放的作用，围绕洛克沙胂降解过程中蚯蚓肠道细菌群落结构与功能变化，阐述蚯蚓肠道细菌在土壤中有机砷转化过程中的作用机制及其与土壤细菌的偶联关系。

TITLE： 

Biotransformation of roxarsone by earthworms and subsequent risk of soil arsenic release: the role of gut bacteria

ABSTRACT：

Earthworms are known as soil ecological engineers, and their gut microbiota plays a crucial role in their ecological services. Although the activity of earthworms increases soil permeability, the earthworm gut forms a mobile anaerobic zone, resulting in significant differences in microbial communities between the earthworm gut and soil. The discussion will mainly introduce the role of earthworms in soil arsenic release under soil roxarsone pollution. We revealed the changes in community structure and function of earthworm gut bacteria during the degradation process of roxarsone. The relationship between soil and gut bacteria was investigated to find the effect and mechanism of earthworm gut bacteria in the transformation of roxarsone in soil.
