Transformations of 1,1,2,2-tetrachloroethane under methanogenic conditions
Article Abstract:
Biotic and abiotic transformations of 1,1,2,2-tetrachloroethane (TeCA) under methanogenic conditions were investigated. It was shown that the degradation of TeCA began without lag with municipal digester sludge. Biotic transformation produced 1,1,2-trichloroethane, trans-1,2-dichloroethene and cis-1,2-dichloroethene while Abiotic degradation produced trichloroethene. Under methanogenic conditions, dichloroelimination and dehydrochlorination were both instrumental in the removal of TeCA and 1,1,2-TCA.

Effect of hydrogen on reductive dechlorination of chlorinated ethenes
Article Abstract:
Hydrogen (H2) is an important electron donor in the reductive dechlorination of chloroethenes. In a study conducted in a methanogenic fluidized bed reactor operating over 14 months, it was found that tetrachloroethene was dechlorinated at a faster rate when H2 levels increased. Additionally, dechloronating bacteria had high levels of H2 utilization than methanogens

Chlorophenol toxicity removal and monitoring in aerobic treatment: recovery from process upsets
Article Abstract:
A study has tested the use of an aerobic fluidized-bed reactor for bioremediation of ground water containing chlorophenols. The experiment achieved over 99% removal of stable chlorophenol. Investigation established mineralization of chlorophenols had occurred. The Microtox acute toxicity assay monitored chlorophenol degradation.
