Enhancement of trichloroethylene degradation in aquifer microcosms bioaugmented with wild type and genetically altered Burkholderia (Pseudomonas) cepacia G4 and PR1
Article Abstract:
Bioaugmentation is a new approach to increase the removal of the pollutant trichloroethylene (TCE) from groundwater. It employs bacterial cultures that can promote transformation of TCE in the absence of inducing compounds such as phenol or toluene. A bacterial strain that has been tested to work effectively in bioaugmentation is Burkholderia (Pseudomonas) cepacia G4. In comparison to conventional bioremediation techniques for groundwater, the use of B. cepacia cultures removes twice the amount of TCE from groundwater.

Effect of three chlorinated ethenes on growth rates for a methanotropic mixed culture
Article Abstract:
The growth rate of methanotrophic bacteria exposed to chlorinated aliphatic carbons (CAH) was analyzed in mixed cultures of methane-oxidizing bacteria. The net growth rate of the cultured methanotropic bacteria was reduced by the presence of CAH. Furthermore, the reduction in growth rate was caused by the inhibition of microbial methane metabolism due to the covalent bonding of CAHs such as 1,1-dichloroethylene and trans-1,2-dichloroethylene.

Electron beam atmospheric pressure cold plasma decomposition of carbon tetrachloride and trichloroethylene
Article Abstract:
A study has been conducted to determine the potential of a tunable plasma reactor in the treatment of air pollution. The device was applied to measure the decomposition of carbon tetrachloride and trichloroethylene under various conditions. The energy expense for the decomposition of chlorinated hydrocarbons was determined by measuring reactor exhaust concentrations.
