The isolated degrading bacteria of integrated methods and degrading bacteria retention support obtained by the integrated method, the method of the degrading bacteria retention carrier to use the contaminated soil recovery or groundwater pollution prevention

摘要

The present invention is aimed at, for example, by decomposing an organic compound in a soil contaminated with organic compounds such as agricultural chemicals by decomposing bacteria to recover soil and to prevent contamination of ground water. In order to achieve the purpose, the present invention integrates a decomposing bacterium of a kind capable of decomposing a specific organic compound and adsorbs the organic compound and accumulates the porous material having a small number of pores in which the decomposing fungus is easy to live In an accumulation method of an isolated decomposing bacterium, only the decomposing fungus is inoculated to the porous material, an accumulation layer comprising the porous material inoculated is formed, and the accumulation layer is recycled by the inorganic salt medium containing only the organic compound as carbon source and nitrogen source It is assumed that the decomposing bacteria are accumulated in the porous material in a state where the degree of accumulation is increased, and the thus obtained degrading bacteria holding carrier is directly buried in the contaminated soil.
