Construction of a Bacterium Spingomonas paucimobilis UT26 Genetically Engineered for Degrading Methyl-parathion and γ-HCH Simultaneously

摘要

@@ Bioremediation of pesticide residues by microorganisms is an efficient and environment friendly method. However, multifunctional indigenous microorganisms of degrading broad-spectrum pesticides, such as organophosphorous and organochlorine pesticide, are rare. Advances in genetic techniques have opened up new avenues to move towards the goal of genetically engineered microorganisms (GEMs) to function as "designer biocatalysts", in which different desirable biodegradation characters from different organisms are brought together in a single host with the aim of specific performance.
