The electrical properties of the pleuropneumonia-like organism A 5969 have been determined over the frequency range from 0.5 to 250 Mcps. The frequency dependence of the dielectric constant and conductivity of PPLO suspensions is completely consistent with the existence of a membrane. The PPLO has an internal conductance which in part reflects its ionic equilibrium with normal nutrient and macromolecular constituents. But it is fairly independent from variation in external ionic strength.
已测定胸膜肺炎样微生物A 5969在0.5至250兆周/秒频率范围内的电学性质。胸膜肺炎样微生物(PPLO)悬浮液的介电常数和电导率对频率的依赖性与细胞膜的存在完全一致。PPLO具有内部电导,这部分反映了其与正常营养成分和大分子成分的离子平衡。但它相当独立于外部离子强度的变化。
