Atrazine, a widely used herbicide, persists for a long period in the environment onced used. It causes metabolic disorders in both animals and humankind. Our team utilized the ribosome switch induced by atrazine, a QS system of Plux and a degrading enzyme to control E.coil’s motility through regulating it’s CheZ gene. Therefore, E.coli can recognize atrazine, recruit team workers, and degrade atrazine. Our team found a transporter of atrazine, which we call TRM. We also mutated the degrading enzyme, TrzN, making it better at degradation. We combined TRM and the TrzN to improve atrazine absorbance and degradation. Moreover, our team are trying to analyze and compare several systems with computer, hoping to find the best one which is equipped with faster moving and quicker degrading. Overall,we believe our system will boost the industrialization, universalization as well as standardization in the field of treatment for atrazine and other versatile small molecules ...more
