  • Method for conversion of a halogenated hydrocarbon using a pseudomonas sp
    Patent number: 6613558
    Abstract: A method of remediating an environment containing soil or water contaminated with a halogenated hydrocarbon, particularly carbon tetrachloride, by introducing a Pseudomonas sp. into the environment. In particular, the method converts carbon tetrachloride in the soil or water into carbon dioxide and a non-volatile water soluble fraction, rather than into a toxic chlorinated hydrocarbon with a lesser number of chlorines. Further, pH adjustment in a particular area provides a niche advantage for the Pseudomonas sp in the soil or water for the conversion.

  • Method and compositions for remediation
    Patent number: 5602036
    Abstract: A method and compositions using a metabolite(s) produced by Pseudomonas KC (DSM 7136) to degrade aliphatic halogenated hydrocarbons. The metabolite(s) is used with an enabling microorganism to degrade the aliphatic halogenated hydrocarbons. The method and compositions are particularly useful with aquifer solutions and soils for removal of carbon tetrachloride.
