An organophosphorus pesticide, ethoprophos, has been widely used in agriculture to control major insect pests. As ethoprophos is a well-known neurotoxin, its accumulation in soils and groundwater is concerning worldwide. In this study, we constructed an artificial ethoprophos-enrichment soil system, and its active concentration in soils was measured by gas chromatography on 15-days intervals during 90 days after ethoprophos treatment. Furthermore, the changes in bacterial community and microorganisms responsible for efficient bioremediation were investigated while ethoprophos was degraded in soils. From 15 to 60 days after the treatment, ethoprophos was actively degraded in soils and members of genera Collimonas and Sphingobium appeared dominantly in a natural microbial community especially in 60-days-after-treatment soil. We isolated a bacterium EP60845 from this soil sample, showing significant ethoprophos biodegradation activity in vitro. When we challenged EP60845 strain into ethoprophos-enrichment soils (250 mg/kg of soil), most ethoprophos was removed within 5-days. Phylogenetic 16S rRNA gene sequence analysis and biochemical properties by API 20GN kit demonstrated that the EP60845 strain was a novel Sphingobium sp., which could be used as an efficient ethoprophos- degrading agents for bioremediation purposes.
