Degradation of chlorinated alkenes such as trichloroethylene (TCE) by methanotrophic bacteria is a promising technology for the remediation of contaminated groundwater. Ultimately, the cost and the success of this approach may be dependent on the influence of groundwater chemistry on degradation rates and extent. TCE can rapidly be reduced to low levels in laboratory cultures growing on defined media. The goal of our research is to quantify the potential effects of groundwater chemistry on the biodegradation of TCE by methanotrophs and to define concentrations of methane that need to be added to the system. This includes work on major nutritional requirements (e.g. PO{sub 4}) but has focused on competitive inhibition and cofactors.
