(JP7171548-A)      De-compsn. of an organochlorine cpd. (I) with a microorganism that is capable of decomposing (I) when activated by an aromatic cpd. is effected by contacting the microorganism with a water-soluble material (II) extracted from a lignocellulose-contg. plant or with p-coumaric acid (III) to activate the microorganism, the decomposing (I) with the activated microorganism.    Also claimed is a process for reducing the amt. of (I) in a (I)-polluted environment, comprising decomposing (I) with a microorganism using a process as above.    Further claimed is a process for decomposing (I) with a microorganism, comprising exposing the microorganism to a cpd. which induces it to express oxygenase and applying the activated microorganism to a locus polluted with (I).    USE -   The process is esp. useful for treatment of soil or effluents contaminated with chlorinated ethylenes, esp. trichloroethylene (TCE) and/or dichloroethylene (DCE).    ADVANTAGE -   In contrast to prior art inducers, (II) and (III) are harmless, readily available and stable in soil, waste water, etc.    (JP7178395-A)      decomposition of an organic chloride cpd. comprises contacting an inducer of a decomposing enzyme for the organic chlorine cpd. with a microbe having the enzyme in a system contg. the organic chloride cpd.. The inducer is p-coumaric acid. The organic chlorine cpd. is pref. a chlorinated ethylene, more pref. trichloroethylene (TCE) and/or dichloroethylene. The microbe is pref. a Pseudomonas genus microbe, esp. Pseudomonas cepacia or Pseudomonas putida.    ADVANTAGE -   The method decomposes organic chlorine cpds. effectively with no problem of environment pollution in the practical waste water treatment and the soil treatment.    (US5693527-A)      De-compsn. of an organochlorine cpd.
