A technique for accumulating and isolating a bacterium capable of degrading a hardly degradable organic chlorine-based pesticide PCNB by improving the existing soil percolation method, and the bacterium capable of efficiently degrading/processing PCNB. To soil containing the organic chlorine-based pesticide PCNB are added pieces of a porous material having a number of pores and being superior in the PCNB-adsorbability to the soil to form an accumulation soil layer (2). Next, an inorganic salt medium (3) utilizing PCNB alone as the carbon source and the nitrogen source is percolated through the soil layer (2) so that an aerobic bacterium Burkholderia cepacia is accumulated on the …
