Summary The microbial communities of two field‐scale pilot sulfate‐reducing bioreactors treating acid mine drainage (AMD), Luttrell and Peerless Jenny King (PJK), were compared using biomolecular tools and multivariate statistical analyses. The two bioreactors were well suited for this study because their geographic locations and substrate compositions were similar while the characteristics of influent AMD, configuration and d...

Summary Aerobic, co‐metabolic bioremediation of trichloroethylene (TCE), cis ‐1,2‐dichloroethylene ( cis ‐DCE) and other chlorinated ethenes with monooxygenase‐expressing microorganisms is limited by the toxic epoxides produced as intermediates. A recombinant Escherichia coli strain less sensitive to the toxic effects of cis ‐DCE, TCE and trans ‐1,2‐dichloroethylene ( trans ‐DCE) degradation has been created by engineering a n...
