Two anaerobic polychlorinated biphenyl-dehalogenating enrichments that exhibit different para-dechlorination specificities
Article Abstract:
Research was conducted to study the substrate specificities of two anaerobic polychlorinated biphenyl (PCB)-dehalogenating enrichments that showed different para-dechlorination specificities. PCBs were extracted by anhydrous diethyl ether and determined with a gas chromatograph. The enriched cultures showed a high degree of specificity for few PCB congeners. Moreover, the addition of both the priming congener 2346-CB and the 2346-CB enrichment did not simulate Aroclor residue dechlorination.

Specificity of reductive dehalogenation of substituted ortho-chlorophenols by Desulfitobacterium dehalogenans JW IU-DC1
Article Abstract:
Examination of the reductive dehalogenation of various substituted ortho-chlorophenols by Desulfitobacterium dehalogenans JW IU-DC1 reveals that position of chlorine significantly influences the rate of dechlorination. Kinetic experiments reveal that dechlorination rate is the highest for 2-chloro-4-R-phenols. Electronic, hydrophobic and stearic constants of the substituent R exhibit no significant correlation with the logarithm of pseudo-first-order rate constants for the dehalogenation.

Comparison of energy and growth yields for Desulfitobacterium dehalogenans during utilization of chlorophenol and various traditional electron acceptors
Article Abstract:
A study was conducted to compare energy and growth yields for Desulfitobactrium dehalogenans with 3-chloro-4-hydroxyphenylacetate as the chlorinated compound and with other nonchlorinated terminal electron acceptors. This is to confirm the assumption that cell yield is equal to the energy yield. Evidence suggests that the dehalogenation reaction results in the formation of similar amounts of energy equivalents.
