土壌中における農薬分解菌の生態と農薬が及ぼす影響評価に関する研究

抄録

Ecological properties of microorganisms involved in aerobic degradation of 2,4-D, 2,4,5-T and salithion and in anaerobic degradation of chlorophenols were examined based on their phylogenetic classification, identification and characterization of genes and enzymes, and/or distribution, diversity and succession in the soil or sediment environment by culture- and molecular-based methods. Side effects of pesticides were evaluated on the soil microbial community by analyzing community-level physiological profiles, on duckweed proliferation considering long-term exposure, recovery potential from the damage and mixture effects of the pesticides, and on river biofilm by assembling a model river biofilm.
