Sequential reductive dechlorination of meta-chlorinated polychlorinated biphenyl congeners in sediment microcosms by two different Chloroflexi phylotypes
Article Abstract:
Assays for both quantitative and qualitative analyses are developed to assess sediment microcosm enrichments that reductively dechlorinated polychlorinated biphenyls (PCBs). The results indicate that individual species within Chloroflexi displays a limited range of congener specificities and that a relatively diverse community of species within a deeply branching group of Chloroflexi with complementary congener specificities is likely required for the reductive dechlorination of different PCBs congeners in the environment.

Microbial dechlorination of 2,3,5,6-tetrachlorobiphenyl under anaerobic conditions in the absence of soil or sediment
Article Abstract:
Research was conducted to examine the microbial dechlorination of 2,3,5,6-tetrachlorobiphenyl (2,3,5,6-CB) under anaerobic conditions in the absence of soil or sediment. Both meta and ortho dechlorination products from 2,3,5,6,-CB were formed by primary enrichment cultures. Results demonstrate that the classical microbial enrichment method using a minimal medium with a single polychlorinated biphenyl congener was selected for ortho dechlorination of 2,3,5,6-CB.

Microbial reductive dechlorination of aroclor 1260 in Baltimore Harbor sediment microcosms is catalyzed by three phylotypes within the phylum chloroflexi
Article Abstract:
The specific dechlorination pathways for aroclor 1260 which were determined in Baltimore Harbor sediment microcosms demonstrate that the variation in dechlorination patterns of congener mixtures typically observed at different polychlorinated biphenyl impacted sites could potentially be mediated by the synergistic activities of relatively few dechlorinating species.
