Observations of protoplasts of Micrococcus lysodeikticus show that removal of the cell wall of this organism decreases the dielectric constant by two orders of magnitude. The upper limit of the effective, homogeneous conductivity for the protoplast is 0.001 mho/m as compared with 0.045 mho/m for the intact cell. These results conclusively demonstrate the(More)
Mycoplasma, in particular species laidlawii and gallisepticum, are found to have a very small, low frequency conductivity as would be predicted by the dielectric model for bacteria and their apparent lack of cell wall structure. Membrane capacitance values for the two organisms are both about 0.9 muF/cm(2), although electron micrographs show that the(More)
Very high dielectric constants have been observed for bacteria at low frequencies. High dielectric constants such as these can be explained by a theory which has been developed for the low-frequency dielectric dispersion of porous charged particles and which has been tested successfully through measurements with ion exchange resins. The bacterial cell wall(More)
