The utilization of monochlorobenzoate isomers (2-, 3- and 4-chlorobenzoate) by anaerobic microbial consortia in River Nile sediments was systematically evaluated under denitrifying, Fe-reducing, sulfidogenic and methanogenic conditions. Loss of all three chlorobenzoates was noted in denitrifying cultures; furthermore, the initial utilization of chlorobenzoates was fastest under denitrifying conditions. Loss of 3-chlorobenzoate was seen under all four reducing conditions and the degradation of chlorobenzoates was coupled stoichiometrically to NO3- loss, Fe2+ production, SO4(2-) loss or CH4 production, indicating that the chlorobenzoates were oxidized to CO2. To our knowledge, this is the first observation of halogenated aromatic degradation coupled to Fe reduction.
在反硝化、铁还原、产硫化物和产甲烷条件下，系统评估了尼罗河沉积物中厌氧微生物群落对一氯苯甲酸异构体（2-、3-和4-氯苯甲酸）的利用情况。在反硝化培养物中，观察到所有三种氯苯甲酸均有损失；此外，在反硝化条件下，氯苯甲酸的初始利用速度最快。在所有四种还原条件下均观察到3-氯苯甲酸的损失，氯苯甲酸的降解与NO3-损失、Fe2+生成、SO4(2-)损失或CH4生成在化学计量上相关联，这表明氯苯甲酸被氧化为CO2。据我们所知，这是首次观察到卤代芳烃降解与铁还原相关联的现象。
