Microorganisms of lake sediment and sewage sludge anaerobically metabolized halobenzoates by a novel pathway. The primary degradative event was loss of the aryl halide without the alteration of the aromatic ring. Dehalogenation required strict anaerobic conditions and depended on the halogen and position, but not the number of halogen substituents. A stable methanogenic bacterial consortium was enriched from sludge and found capable of dehalogenating and often mineralizing a variety of halobenzoates to CH(4) and CO(2). The results suggest that reductive dehalogenation of aromatics could be important in removal of some chlorinated xenobiotics from the environment.
湖泊沉积物和污水污泥中的微生物通过一种新途径对卤代苯甲酸进行厌氧代谢。主要的降解事件是芳基卤化物的丢失，而不改变芳环。脱卤化作用需要严格的厌氧条件，并取决于卤素和位置，而与卤素取代基的数量无关。从污泥中富集了一种稳定的产甲烷细菌混合物，发现它能够脱卤化并经常将各种卤代苯甲酸矿化为 CH(4)和 CO(2)。研究结果表明，芳香族化合物的还原脱卤作用可能对从环境中去除某些氯化外来化合物很重要。
