FIG. 1.

(A) Rate of chlorine removal from 2,3,5,6-CB by enrichment cultures containing 0.1% Baltimore Harbor sediment. The dechlorination pathway of 2,3,5,6-CB by ortho-dechlorinating enrichment cultures is shown in the inset. (B) Community profiles of bacterial 16S rDNA clones from Baltimore Harbor enrichment cultures incubated with (□) and without (■) 2,3,5,6-CB. Samples for phylogenetic analysis were taken at day 137, as indicated for panel A. Both enrichment cultures were amended with a mixture of three fatty acids as carbon sources. (C) Community profiles of archaeal 16S rDNA clones from Baltimore Harbor enrichment cultures incubated with (□) and without (■) 2,3,5,6-CB.
