For enforcement of effective bioremediation, it is necessary to maintain the activity of organic pollutant-degrading microorganisms in soil where a great variety of microorganisms inhabit. A purpose of this study is to elucidate a factor necessary for microbial consortium to express ability for degradation of the target pollutant in actual contaminated soil stably. Chlorinated ethylene-degrading consortium, preferential aromatic hydrocarbon-degrading consortium, and highly-concentrated polycyclic aromatic hydrocarbon-degrading consortium are used in this research. Dynamics of microbial population and substances exchanging among microorganisms during the degradation of each pollutants were analyzed. In addition, the examination of a material exchanged between microbes was carried out. From those results, the importance of symbiosis system of microorganisms in the degradation process of pollutants was elucidated.

为了实施有效的生物修复，有必要保持土壤中有机污染物降解微生物的活性，土壤中有各种各样的微生物栖息。本研究的目的是阐明微生物群落稳定表达对实际污染土壤中目标污染物降解能力的必要因子。采用氯化乙烯降解联合体、优先芳烃降解联合体和高浓度多环芳烃降解联合体进行研究。分析了各污染物降解过程中微生物种群和物质交换的动态。此外，还进行了微生物间交换物质的检测。由此，阐明了微生物共生系统在污染物降解过程中的重要性。
