环境因子对厌氧微生物脱卤的影响研究进展

有机卤代物在工农业生产中的广泛应用及不合理处置与排放导致其成为地下环境中普遍存在的一类污染物，严重威胁地下生态系统功能、饮用水安全和人类健康。有机卤呼吸细菌在有机卤污染场地的原位生物修复中起到了至关重要的作用。本文简要概述了影响和制约有机卤呼吸微生物生长代谢及脱卤活性的一些关键环境因子，如pH、温度、盐度、电子供受体和氧气等，并且对有机卤呼吸细菌未来的研究方向提出展望，以期为污染场地原位生物修复工程的有效实施提供理论与技术参考。

Effects of environmental factors on anaerobic microbial dehalogenation: a review

Wide applications and improper treatments of organohalides in industry and agriculture lead to their ubiquitous presence in the underground environments, posing a great threat to ecosystem functions, drinking water safety and human health. Organohalide-respiring bacteria (OHRB) are crucial forin situ bioremediation of organohalide-contaminated environments. This review summarizes environmental factors (e.g., pH, temperature, salinity, electron donors and acceptors, oxygen) that may impact the growth, metabolisms and dechlorination activities of OHRB, and discusses the future research of OHRB, which is intended to provide theoretical and technical reference for the effective implementation of in situ bioremediation to clean up organohalides-contaminated sites.
