豆科植物通过根瘤菌共生固氮(SNF)将大气氮转化为可用氮,但作物品种与根瘤菌菌株间不兼容或次优互作常导致固氮率下降。为低成本、高通量筛选根瘤菌接种剂,作者建立了一种基于叶片打孔的全细胞生物传感器检测方法。该方法利用GlnLux生物传感器,即谷氨酰胺(Gln)营养缺陷型大肠杆菌菌株表达组成型lux操纵子,在检测到Gln后产生生物发光。...

本研究构建了一种用于检测谷氨酰胺(glutamine, Gln)的大肠杆菌全细胞生物传感器 GlnLux。该传感器以谷氨酰胺营养缺陷型大肠杆菌 JW3841-1(glnA732::Kan)为细胞换能器,通过转入由组成型 T7 启动子驱动的费氏弧菌 luxCDABE 发光操纵子质粒 pT7-lux 实现信号输出。由于菌株缺失谷氨酰胺合...
