SOIL REMEDIATION SYSTEM

摘要

A system for bioremediating soil and groundwater contaminated with high substituted chlorinated hydrocarbons, such a trichloroethylene and perchloroethylene, by a strain of Ralstonia eutropha with a non-cometabolic pathway for metabolizing chlorinated hydrocarbons, and does not require induction.

主权项

1. A method for remediating contaminated soil containing chlorinated hydrocarbons under a water table comprising:
injecting below the water table an oxygen-containing gas under conditions to dissolve oxygen into the water table; introducing nutrients below the water table; introducing Ralstonia eutropha bacteria with a non-cometabolic pathway for metabolizing chlorinated hydrocarbons below the water table to directly and non-inductively metabolize the chlorinated hydrocarbons as a non-cometabolic substrate; extracting gas the in a vadose zone above the water table that is derived from metabolism of the strain of Ralstonia eutropha bacteria with the chlorinated hydrocarbons.
