从活性污泥中分离的甲基对硫磷降解菌接种于含有甲基对硫磷的土壤中，表现了较强的降解农药残留的牛态效应。在盆栽试验中，处理的各叶片变黄程度比对照均要轻，统计差异显著，稻米与稻壳中甲基对硫磷处理比对照下降了８２．２－１００％。田间试验中，农药加菌，农药加有机肥加菌的处理，其稻米中的甲基对硫磷残留均检测不到，而对照（只施农药不加菌），稻米中的甲基对硫磷含量为０．０６５ｍｇ／ｋｇ，超过国家标准（０．０５ｍｇ／ｋｇ）。
Methyl parathion-degrading bacteria isolated from activated sludge were inoculated into the soil containing methyl parathion, which showed a strong effect of degrading pesticide residues. In the pot experiment, the degree of yellowing of each leaf was lighter than the control, the difference was significant, and the content of methyl-parathion in rice and rice husk decreased by 82.2-100% compared with the control. In field trials, pesticide plus bacteria, pesticides and organic fertilizer plus bacteria treatment, the rice parathion residues were not detected, while the control (only pesticides without bacteria), the methyl-sulfur in rice Phosphorus content of 0.065mg / kg, more than the national standard (0.05mg / kg).
