3.1.8.1 | agriculture |
agricultural soils are often co-contaminated with different types of pesticides. For example, organophosphates and pyrethroids usually are applied together for pest control. So far, microorganisms with both OP- and pyrethroid-degrading activity have not been isolated from natural environments. Alternatively, construction of engineered microbes with broad-spectrum pesticide-degrading activity may be a promising strategy for bioremediation of mixed pesticides-contaminated soil. To construct multifunctional pesticide degrading microorganisms, the co-expression of multiple degrading enzymes in a host strain may be a feasible approach. Both MPH and PytH are coexpressed in a soil bacterium Pseudomonas putida KT2440, resulting in an engineered strain with the capability to simultaneously degrade OPs and pyrethroids. Six pesticides (methyl parathion, fenitrothion, chlorpyrifos, permethrin, fenopropathrin, cypermethrin) can be effectively degraded by the engineered Pseudomonas putida KT2440. Therefore, the engineered Pseudomonas putida KT2440 could potentially be applied for in situ bioremediation of soil co-contaminated with organophosphates and pyrethroids |

3.1.8.1 | degradation |
a series of substituted phenoxyalkyl pyridinium oximes enhance the degradation of surrogates of sarin (i.e. nitrophenyl isopropyl methylphosphonate, NIMP) and VX (i.e. nitrophenyl ethyl methylphosphonate, NEMP). Neither NIMP nor NEMP is hydrolyzed effectively by paraoxonase PON1 if one of these oximes is absent. In the presence of eight novel oximes, PON1-mediated degradation of both surrogates occurs |
