DEGRADATION BACTERIUM CAPABLE OF AEROBICALLY DEGRADING ORGANIC CHLORINATED COMPOUND IN SOIL, ACCUMULATION OR ISOLATION OF THE DEGRADATION BACTERIUM AND DEGRADATION BACTERIUM SUPPORT SUPPORTING THE DEGRADATION BACTERIUM

摘要

PROBLEM TO BE SOLVED: To provide a technique for improving conventional soil-recycling methods and accumulating and isolating bacteria capable of degrading a slightly degradable organic chlorinated pesticide: PCNB in a short period, and to provide the degradation bacterium capable of efficiently treating the PCNB. SOLUTION: This aerobic bacterium: Burkholderia cepacia KTYY97 (FERM P-16809) is obtained by mixing a soil containing a slightly degradable organic chlorinated pesticide: PCNB with the crushed product of a porous material having innumerable pores and having a larger adsorption force for the PCNB than that of the soil to form a soil layer 2 for accumulation and subsequently circulating an inorganic salt culture medium 3 containing only the PCNB as carbon and nitrogen sources to the accumulation soil layer 2 to accumulate the aerobic bacterium: Burkholderia cepacia KTYY97 (FERM P-16809) in the crushed porous material.
