Methods:The tests were based on the bacterial's recovery rate of colonies count and the colour show test by TTC gradient concentration in culture medium.

方法：用TTC梯度浓度培养基进行细菌菌数计数的回收率试验和菌落显色试验。

It is proposed that the cell might be used in applications which require relatively low power consumption, for example sensors of various kinds or emergency signaling units, and that the devices might be used best in desert or warm coastal regions where the water is readily evaporated from the cell, thus maintaining its concentration gradient.
