A multi-channel bioluminescent bacterial biosensor for the on-line detection of metals and toxicity. Part I: design and optimization of bioluminescent bacterial strains.

本研究通过基因工程构建可诱导发光的工程大肠杆菌菌株，并对其进行表征与优化，用于重金属在线检测。首先比较丙酮酸、葡萄糖、柠檬酸、稀释Luria–Bertani和乙酸等碳源，发现乙酸培养基可获得最佳诱导比。所构建的三种诱导型菌株E. coli DH1 pBzntlux、pBarslux和pBcoplux在30 °C过夜培养14 h后可用...
