Abstract The report summarizes initial efforts: to isolate microorganisms capable of anaerobic dehalogenation; to examine the nutritional requirements of dehalogenating enrichments and a dehalogenating consortium; and to study the genetics of dehalogenation. Enrichments using secondary anaerobic digestor sludge containing either 3- or 4-chlorobenzoate were established with a variety of terminal electron acceptors. Degradation of 4-chlorobenzoate was not observed. Degradation of 3-chlorobenzoate (3CB) was observed after 10-23 weeks. Use of a 3CB degrading consortium revealed that the microorganisms capable of benzoate degradation and methanogenesis were lost but dechlorination continued. Genetic studies using a pure culture of strain DCB-1 found the strain to be suitable for cloning manipulations.
