Evaluation of Enhanced Bioremediation for Reductive Dechlorination of Tetrachloroethene (PCE): Microcosm Study
… were capable of partial dechlorination of tetrachloroethene (PCE) to cis-dichloroethene (cis-DCE). This study attempts to achieve complete reductive dechlorination with amendments to static microcosms to test the hypotheses that nutrient-limited or microorganism-limited conditions exist in …

Microbial Growth On Anthropogenic Compounds By Reductive Dehalogenation Or Oxidation
… some of these compounds and, in the case of tetrachloroethene (PCE), detoxify it by producing ethene. Its genome contains a putative prophage, which could inhibit its ability to grow to high densities and cause phage mediated cell death. This phage was evaluated by genomic comparisons and …

Investigating Controls on Variation in Isotopic Fractionation during Biodegradation of Chlorinated Ethenes and Ethanes
… isotope fractionation observed for anaerobic tetrachloroethene (PCE) biodegradation has been a matter of longstanding controversy. This work found the magnitude of carbon isotope fractionation for PCE biodegradation is related to the phylogenetic relationships between PCE-degrading organisms, …

Advanced Data Analysis Of In-Situ Bioremediation Site Data Using Dimensionality Reduction Techniques
… remediation technology for the treatment of tetrachloroethene (PCE) and trichloroethene (TCE) due to its inexpensiveness and flexibility for low-strength remediation applications. A typical ISB implementation involves the collection of large amounts of data to address the many possible …

Bioindicators of Reductive Dechlorination in a Dehalococcoides ethenogenes-Containing Mixed Culture: Transcriptional Trends With Respect to Substrate Type, Substrate Concentration, and Culture Operation
… (D2) capable of reductively dechlorinating tetrachloroethene (PCE) successively to trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), vinyl chloride (VC), and non-toxic ethene using H2 as electron donor. Gene transcripts associated with general cell activity, including those corresponding …

COMBINING GEOCHEMICAL AND NUMERICAL MODELING FOR CHLORINATED SOLVENTS GROUNDWATER CONTAMINATION
… chloroethene. The more chlorinated ones such as tetrachloroethene (PCE) and trichloroethene (TCE) are better degraded via reductive dechlorination (RD) under anaerobic conditions, while the less chlorinated compounds such as dichloroethene (DCE) and vinyl chloride (VC) are better degraded via …

Hydraulic and Electrokinetic Delivery of Remediants for In-situ Remediation
… leading to complete in-situ tetrachlorothene (PCE) degradation. To the authors’ knowledge, this study was the first to combine EK and ERH for persulfate delivery and activation for low permeability soil remediation.
