Microbial degradation of DDD and DDE under anaerobic conditions have been reported. For DDE the most probable path of transformation is to DDMU (1-chloro-2,2-bis-(p-chlorophenyl)ethylene) as the next following product via reductive dechlorination (3 times faster than DDD; . The dominant anaerobic transformation pathway of DDT results in both DDD and DDMS (1-chloro-2,2-bis-(p-chlorophenyl)ethane), as shown, e.g. by and . TPs other than DDD and DDE were not analyzed in the current study.
