Abstract Anaerobic degradation of 2,4-dichlorophenol (2,4-DCP) between 5 and 72C was investigated. Anaerobic sediment slurries prepared from local freshwater sediments were partitioned into anaerobic tubes or serum vials, which then were incubated separately at the various temperatures. Reductive 2,4-DCP dechlorination occurred only in the temperature range between 5 and 50C, although methane was formed up to 60C. In sediment samples from two sites and at all temperatures from 5 to 50C, 2,4-DCP was transformed to 4-chlorophenol (4-CP). The 4-CP intermediate was subsequently degraded after an extended lag period in the temperature range from 15 to 40C. Adaptation periods for 2,4-DCP transformation decreased between 5 and 25C, were essentially constant between 25 and 35C, and increased in the tubes incubated at temperatures between 35 and 40C. This suggests that at least two different organisms were involved in the transformation of 2,4-DCP to 4-CP.
