1 引 言细胞传感器是微生物传感器的一个重要分支 .微生物传感器依据微生物响应机理的不同可分成如下两种 :一种是利用微生物体内的各种酶系及代谢系统来检测相应底物 ,这类统称为间接型微生物传感器 ;另一种是利用微生物本身能直接在电极上反应的特性来检测某一物质量 ,这类
1 Introduction Cell sensor is an important branch of microbial sensor.Microbial sensor based on the mechanism of microbial response can be divided into the following two: one is the use of microorganisms in vivo enzyme system and metabolic system to detect the corresponding substrate, collectively referred to as Indirect microbiological sensor; the other is the use of microorganisms themselves can directly react on the electrode to detect a certain amount of property, this type
