Abstract
It is an object of the invention to improve a conventional soil percolation technique to thereby provide a method of enriching and isolating decomposing bacteria decomposing an organochlorine agricultural chemical PCNB which is difficult to decompose, in a short time period, and to provide decomposing bacteria for efficiently processing PCNB. To practice the method, an enrichment soil layer is formed by mixing a soil containing an organochlorine agricultural chemical PCNB with a fragmented porous material having an infinite number of micropores and at the same time a greater adsorptivity for adsorbing PCNB than the soil, and an inorganic salt medium containing a carbon and nitrogen source, the carbon and nitrogen source being formed by only PCNB, is circulated through the enrichment soil layer , thereby enriching the aerobic bacteria in the fragmented porous material.
