“…3,4-DCA is accumulated as a nal diuron degradation product (Tixier et al 2000;Giacomazzi and Cochet 2004) and is more persistent than its parent compound (Tixier et al 2000). In this study, 3,4-DCA was further metabolised to produce 4-chloroaniline, aniline, and chlorobenzene, and similar ndings have been reported by others (Ha and Nguyen 2019). DCMPU is usually produced during diuron degradation under aerobic conditions and is sometimes formed under anoxic conditions (Stasinakis et al 2009).…”

“…This result could be attributed to the chloride absorption by bacteria, retention of chloride in unknown metabolites, or both. These phenomena were also for anaerobic degradation of other organic compounds (Ha 2018;Ha and Nguyen 2019).…”

The herbicide diuron is extensively used in the agriculture sector and is detected widely in the environment. Although several studies on the degradation of diuron by aerobic micro-organisms have been reported, the degradation of diuron by anaerobic micro-organisms has not been received much attention. Also, no pure culture that can degrade diuron under anaerobic conditions has yet been reported. The evaluation of diuron degradation in the soil and sediment slurries showed that diuron led to a decrease in the biodiversity of the bacterial communities. Two mixed bacterial cultures, one from the soil and the other from sediment slurries, were isolated from the enrichment media under anaerobic conditions. After 30 days of incubation at 30 oC, the mixed bacterial culture from the soil degraded 84.5 ± 5.5%, and that from the sediment slurry degraded 94.5 ± 3.0% of diuron in liquid mineral medium at an initial concentration of 20 mg/L. 1-(3,4-dichlorophenylurea (DCPU), 3-(3-chlorophenyl)-1,1-dimethylurea (CPDMU), and 3,4-dichloroaniline (3,4-DCA) were the major diuron metabolites produced by both the indigenous micro-organisms and the isolated bacteria.
