Systematic evaluation of pigment-based whole-cell lead biosensors: challenges in genetic circuit engineering and critical considerations for background noise control.
尽管全细胞生物传感器在 Pb(II) 检测中取得进展,但背景泄漏和有限动态范围限制其现场应用。本研究系统评价四种不同 pbr 操纵子,并优化遗传电路架构,以开发高性能基于色素的 Pb(II) 生物传感器。将来自 Cupriavidus metallidurans、Pseudomonas aeruginosa 和 Klebsiella...
