(JP8140665-A)      A halogenated organic acid (I) is decomposed by culturing, in presence of (I), a microorganism (M) having a dehalogenase capable of decomposing (I).    An aliphatic organochlorine cpd. (II) is decomposed using two kinds of microorganism, (M1) and (M2), together; M1 introduces an oxygen atom into (II) to convert (II) into an epoxide, and M2 decomposes a halogenated organic acid into chlorine ion, carbon dioxide and water.    Also claimed is a biologically pure culture of a microorganisms having a dehalogenase able to decompose (I) hydrolytically, esp. Renobacter sp AC, FERM P-14641.    Further claimed is the treatment of a gas, soil or water with P-14641.    (I) is halogenated acetic or propionic acid, e.g. chloro-, dichloro-, trichloro- or bromo-acetic acid, or chloro- or dichloro-propionic acid (II) is trichloroethylene. (M) and M2 are of genus Renobacter. (M) is esp. P-14641. M1 is of genus Pseudomonas or Corynebacterium.    USE -   The methods are of use in remedying environments, e.g. soil or ground or waste water, polluted with (I) or (II).
