TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Process: The organic compounds decomposed by the microorganisms, are preferably chlorinated aliphatic compounds such as tri- or di-chloroethylene. The contaminated resource or environment that should be recovered is waste water, soil, industrial waste liquids or under ground contaminated water. The microorganism is preferably carried on a support. For recovering contaminated underground water/waste liquid, the contaminated sample is introduced into a container containing the support to which the microorganism is fixed, and the purified sample is received at the other end of the container. In case of recovering contaminated soil, the microorganism is introduced into the soil contaminated with the organic compound. Preferably, the microorganism is provided to an inoculation well provided in the soil. Alternately, the contaminated soil is introduced into the microorganism inoculum for the recovery process. The method is also carried out by mixing the inoculum and the contaminated soil or by contacting the support carrying a microorganism with the contaminated soil. For purifying contaminated air, the air is introduced into the inoculum containing microorganisms, or is made to contact with the support carrying the microorganism, where contaminated air is introduced from one end of the container containing support and purified air is recovered from the other end.    TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Microorganism: The microorganism which degrades organic compounds comprises a recombinant nucleic acid molecule which encodes the organic compound degradation enzyme. Preferably, the gene is of Burkholderia cepacia KK01 strain. Also the microorganism coexpresses a gene encoding recombinant alkylated DNA repair enzyme, of Escherichia coli K12 strain. Most preferably the microorganism is E.coli transformed with the above mentioned nucleic acids. The organo chlorine decomposing microorganism may be chosen from Pseudomonas, Burkholderia or Acinetobacter genus. SPECIFIC MICROORGANISMS - The microorganism that has organo-chlorine compounds decomposition ability, is JM1 FERMBP-5352, Burkholderia cepacia KK01 strain FERMBP-4235 (claimed).    EXAMPLE - No suitable example.
