It is a promising candidate for bioaugmentation at cis-DCE-contaminated sites where cis-DCE has migrated downgradient into an aerobic zone. Addition of the strain can circumvent the problems associated with cometabolic oxidation as a bioremediation strategy because it catalyze

Bioaugmentation for the , Aerobic Cometabolism of Chlorinated Solvents,us transformation of the CAHs by nonspecific oxygenase enzymes. The process most commonly applied in the field is to stimulate indigenous microorganisms through additions of an appropriate cometabolic growth substrate and oxygen. This biostimulation strategy faces several challenges, including subst

The key to this strategy is that strain KC secretes a compound (pyridine-2,6-bis-thiocarboxylate, or PDTC) that promotes chemical dechlorination of CT outside the cell. Strain KC is a highly motile (chemotactic toward nitrate) facultative aerobe capable

Although the effort yielded important insights into the biodegradation of MTBE and its daughter product .-butyl alcohol (TBA), bioaugmentation for these contaminants is not used currently, and it is likely to remain a minor field of endeavor

Research Needs for Bioaugmentation,er provides an introduction to the future potential of bioaugmentation (and bioremediation in general), and seeks to identify the research needs that, if addressed, will help realize this potential. First, a discussion of bioremediation at the molecular, organismal, community and ecosystem scales is
