Measurements have been made of the modulated light-induced changes in conductivity and the associated relaxation times of bacteriorhodopsin in a variety of strong electrolytes, both unbuffered and buffered. The effects of pH and temperature variation have been studied as well as the effect of adding valinomycin. Two relaxation times can be distinguished: a fast lifetime associated with protonation-deprotonation, and a slow lifetime associated with ion binding. The ion-binding effects appear to be cation specific.
已对多种强电解质（包括未缓冲和缓冲的）中细菌视紫红质的电导率调制光诱导变化及其相关弛豫时间进行了测量。研究了pH值和温度变化的影响以及添加缬氨霉素的影响。可以区分出两种弛豫时间：与质子化 - 去质子化相关的快速寿命，以及与离子结合相关的缓慢寿命。离子结合效应似乎具有阳离子特异性。
