Abstract
Studies of the effective, homogeneous, dielectric constants of bacteria are used to show that the resistances of their cytoplasmic membranes are too great to explain the low-frequency conductivities which have been observed for these organisms. This reaffirms the conclusion that at low frequencies the conductivities of bacteria reflect properties of their cell walls. In the organisms studied, the conductivities of the cell wall region are as great as the conductivities of the cytoplasm. This is true even though the ion concentration in the environment is much less than that in the cells. The mobile ions of the wall are presumed to be counterions for fixed charges in this region.
摘要
对细菌有效、均匀介电常数的研究表明，其细胞质膜的电阻过大，无法解释这些生物体所观察到的低频电导率。这再次证实了一个结论，即在低频下，细菌的电导率反映了其细胞壁的特性。在所研究的生物体中，细胞壁区域的电导率与细胞质的电导率一样高。即便环境中的离子浓度远低于细胞内的离子浓度，情况依然如此。细胞壁中的移动离子被认为是该区域固定电荷的抗衡离子。
