<p>The invention provides a method for removing a chlorinated hydrocarbon from soil or groundwater comprising the steps of adding to chlorinated hydrocarbon containing soil or groundwater a chlorinated hydrocarbon metabolizing microbial culture of the genus Arthrobacter and providing conditions supporting growth and reproduction of the microbial culture. The microbial culture removes chlorinated hydrocarbons including those selected from the group consisting of DDT, dieldrin, toxaphene, aldrin, 1,1,1-trichloroethane, 1,1-dichloroethane, 1,2-dichloroethene, trichloroethylene, methylene chloride, chloroform, or mixtures thereof. The soil or groundwater is treated in place, or removed, cleansed and returned. The invention provides a purified and isolated microbial culture of the genus Arthrobacter adapted to use chlorinated hydrocarbons as a sole carbon source.</p> |
