Construction of a sensitive and specific lead biosensor using a genetically engineered bacterial system with a luciferase gene reporter controlled by pbr and cadA promoters.

细菌生物传感器是指经遗传工程改造、在环境物理或化学刺激下产生可测量信号的细菌体系。本研究设计并评价了两种以荧光素酶报告基因（luc+）为输出元件的细菌生物传感器：pGL3-luc/pbr和pGL3-luc/cad。前者将来自铜矿杆菌Cupriavidus metallidurans CH34质粒pMOL30的pbr启动子与pbrR调...
